If your fitness goals are to get strong and build hard, visible muscle, then you’re going to want to train in three phases according to Heath. Strength, conditioning, and a blend of the two that works for you. “If you can get to the gym 4-5 days a week, that would be perfect,” he says. “You can still do chest/tri’s, back/bi’s, legs, shoulders, and make the fifth day a cleanup day, meaning focus on body parts you may be weaker in.” Check out Heath’s guide to finding your best muscle-building routine.
I HATE that the resistance training community can be so tribal. I have been preaching to bodybuilders for years about the benefits of powerlifting, or Olympic lifting or kettlebells or even Crossfit style conditioning and many have been receptive. Learn from each other and achieve levels of fitness you simply could not have otherwise. Don’t brush off bodybuilding wisdom…it could be the missing factor in your program.
Sports where strength training is central are bodybuilding, weightlifting, powerlifting, and strongman, highland games, hammer throw, shot put, discus throw, and javelin throw. Many other sports use strength training as part of their training regimen, notably: American football, baseball, basketball, football, hockey, lacrosse, mixed martial arts, rowing, rugby league, rugby union, track and field, boxing and wrestling.
Creatine is produced endogenously at an amount of about 1 g/d. Synthesis predominately occurs in the liver, kidneys, and to a lesser extent in the pancreas. The remainder of the creatine available to the body is obtained through the diet at about 1 g/d for an omnivorous diet. 95% of the bodies creatine stores are found in the skeletal muscle and the remaining 5% is distributed in the brain, liver, kidney, and testes [1]. As creatine is predominately present in the diet from meats, vegetarians have lower resting creatine concentrations [2].
In regard to bioenergetics, phosphorylated cyclocreatine appears to have less affinity for the creatine kinase enzyme than phosphorylated creatine in terms of donating the high energy phosphate group (about 160-fold less affinity) despite the process of receiving phosphorylation being similar.[104][105] When fed to chickens, phosphorylated cyclocreatine can accumulate up to 60mM in skeletal muscle,[106] which suggests a sequestering of phosphate groups before equilibrium is reached.[105] Cyclocreatine still has the capacity to donate phosphate, however, as beta-adrenergic stimulated skeletal muscle (which depletes ATP and glycogen) exhibits an attenuation of glycogen depletion (indicative of preservation of ATP) with phosphocreatine.[102]

Weak, underdeveloped glutes can be a problem if you have a history of back pain and can compromise your hip mobility and set the stage for hip impingement (if you’ve ever gotten off your bike and couldn't stand up straight without some effort, you know how that feels). “Strong glutes can prevent those issues,” says McGill. But here’s the good news: You can build yours on and off the bike with a few simple moves.
These effects are secondary to creatine being a source of phosphate groups and acting as an energy reserve. The longer a cell has energy, the longer it can preserve the integrity of the cell membrane by preserving integrity of the Na+/K+-ATPase and Ca2+-ATPase enzymes.[241][235][236] Preserving ATP allows creatine to act via a nongenomic response (not requiring the nuclear DNA to transcribe anything), and appears to work secondary to MAPK and PI3K pathways.[226]
Injections of creatine are known to be neuroprotective against low oxygen levels (hypoxia) even to neonatal rats.[532] This is thought to be associated with the increased collective pool of phosphocreatine and creatine.[236] Since oral ingestion of creatine by the mother increases brain concentrations of creatine by 3.6% in the fetus prior to birth,[531] it is thought to be protective in the fetuses subject to hypoxic (low oxygen) stressors, such as a caesarean section. 

Whey Protein: This protein is a product of cheese making. Whey is the watery milk that’s separated and removed from the cheese curd. Through further processing, it’s turned into a powder. Whey protein is a great source of amino acids and nutrients. You can find whey protein from a number of manufacturers in different flavors including vanilla and chocolate.
Activation of NMDA receptors is known to stimulate Na+,K+-ATPase activity[218] secondary to calcineurin,[219] which which has been confirmed with creatine in hippocampal cells (0.1-1mM trended, but 10mM was significant). This is blocked by NMDA antagonists.[220] This increase in Na+,K+-ATPase activity is also attenauted with activation of either PKC or PKA,[220] which are antagonistic with calcineurin.[219][221]
Lie on your left side. Rest your head on your left arm. Bend your hips to approximately 45 degrees and bend your knees at 90 degrees. Make sure one hip is lying above the other so your knees are stacked perfectly and your feet are aligned with your back. Now, float the upper leg upwards while keeping your feet in contact with one another, then return. Repeat for required reps, then switch sides.
Bodybuilders often split their food intake for the day into 5 to 7 meals of roughly equal nutritional content and attempt to eat at regular intervals (e.g. every 2 to 3 hours). This method can serve two purposes: to limit overindulging in the cutting phase, and to physically allow for the consumption of large volumes of food during the bulking phase. Contrary to popular belief, eating more frequently does not increase basal metabolic rate when compared to the traditional 3 meals a day. While food does have a metabolic cost to digest, absorb, and store, called the thermic effect of food, it depends on the quantity and type of food, not how the food is spread across the meals of the day. Well-controlled studies using whole-body calorimetry and doubly labeled water have demonstrated that there is no metabolic advantage to eating more frequently.[38][39][40]

Similarly to complex training, contrast loading relies upon the enhanced activation of the nervous system and increased muscle fibre recruitment from the heavy set, to allow the lighter set to be performed more powerfully.[41] Such a physiological effect is commonly referred to as post-activation potentiation, or the PAP effect. Contrast loading can effectively demonstrate the PAP effect: if a light weight is lifted, and then a heavy weight is lifted, and then the same light weight is lifted again, then the light weight will feel lighter the second time it has been lifted. This is due to the enhanced PAP effect which occurs as a result of the heavy lift being utilised in the subsequent lighter lift; thus making the weight feel lighter and allowing the lift to be performed more powerfully.

How to do it: From your hands and knees, move your hands out from under your shoulders so your arms are extended at roughly a 45° angle. Tuck your toes under your feet. As you exhale, straighten your legs and lift your butt and midsection toward the ceiling. Your knees should be slightly bent, and you should be up on your toes. Now drop your head between your arms, straighten your arms and legs, and push back on your feet. Press your heels into the floor, or as far as you can go. Hold for two seconds.

In 1912, Harvard University researchers Otto Folin and Willey Glover Denis found evidence that ingesting creatine can dramatically boost the creatine content of the muscle.[5][non-primary source needed] In the late 1920s, after finding that the intramuscular stores of creatine can be increased by ingesting creatine in larger than normal amounts, scientists discovered creatine phosphate, and determined that creatine is a key player in the metabolism of skeletal muscle. The substance creatine is naturally formed in vertebrates.[6]
show that total testosterone levels increase after exercising, especially after resistance training. Low testosterone levels can affect your sex drive and your mood. The good news is that exercise improves mood and stimulates brain chemicals to help you feel happier and more confident. Exercise also boosts energy and endurance, and helps you to sleep better. Fitness experts recommend 30 minutes of exercise every day.
If you’re the kind of person who shops for popular dietary supplements like protein or collagen powder, you’ve probably seen another popular bottle on the shelves: creatine. This supplement, which can be taken as a powder or liquid (and usually in some kind of healthy shake), is a staple in the bodybuilding community thanks to its ability to help you pack on muscle and work out longer and harder. (1) While creatine is generally considered safe — and is one of the most researched supplements out there (according to a review published in July 2012 in the Journal of the International Society of Sports Nutrition) — it is still a supplement, which means it’s not regulated by the Food and Drug Administration (FDA) and product claims don’t necessarily need to be substantiated (though the FDA can pull products that are found to be unsafe). (2,3)
So, one way to make the soreness go away, at least temporarily, is to continue exercising.  This increases blood flow to the muscles and helps them heal.  However, remember that we still need them to heal. So if you’re sore from heavy squats, don’t turn around and do heavy squats again. Try doing squats with no weight or yoga/stretching to help bring the soreness down.
Researchers described the study as one of the first to examine how strength training can reduce the risk of cardiovascular disease, separate from the effects of aerobic activity like running or long walks. The point: for those who are not meeting recommended guidelines for aerobic activity—perhaps because they lack the time—bursts of weight training can be enough.
Whether you love or hate ‘em, squats are one of the best butt exercises for strengthening your backside. Experts say that if you want to run faster, jump higher and lift heavier, squatting low is the way to go. They might look easy, but prepare to work when you add a barbell, slam ball or heel raise to the mix. These squat variations not only add some power to your jumps and kicks, but they also help improve your knee stability and range of motion. So how low can you go? Try these exercises to find out.
Fatherhood decreases testosterone levels in men, suggesting that the emotions and behavior tied to decreased testosterone promote paternal care. In humans and other species that utilize allomaternal care, paternal investment in offspring is beneficial to said offspring's survival because it allows the parental dyad to raise multiple children simultaneously. This increases the reproductive fitness of the parents, because their offspring are more likely to survive and reproduce. Paternal care increases offspring survival due to increased access to higher quality food and reduced physical and immunological threats.[60] This is particularly beneficial for humans since offspring are dependent on parents for extended periods of time and mothers have relatively short inter-birth intervals.[61] While extent of paternal care varies between cultures, higher investment in direct child care has been seen to be correlated with lower average testosterone levels[62] as well as temporary fluctuations. For instance, fluctuation in testosterone levels when a child is in distress has been found to be indicative of fathering styles. If a father's testosterone levels decrease in response to hearing their baby cry, it is an indication of empathizing with the baby. This is associated with increased nurturing behavior and better outcomes for the infant[63].
Testosterone replacement therapy is currently only FDA approved for men who have been diagnosed with hypogonadism, but it’s also prescribed off-label for older men who take it in hopes that it will improve their libido. The use of testosterone therapy is increasingly common in the United States, with more than 2 million men receiving the therapy. Not every man benefits from taking testosterone supplements. Testosterone is available in different forms, including topicals such as gels, creams, and patches; injections; and pellets that are surgically placed directly beneath the skin. (7)
As scientific research progressed, it became apparent that the best types of protein came from milk and eggs. That led to the next great revolution in sports nutrition, namely the engineered food, pioneered by Scott Connelly, M.D., a critical care specialist from Northern California who teamed with a young entrepreneur named Bill Phillips from Golden, Colorado.
The gluteus medius muscle originates on the outer surface of the ilium between the iliac crest and the posterior gluteal line above, and the anterior gluteal line below; the gluteus medius also originates from the gluteal aponeurosis that covers its outer surface. The fibers of the muscle converge into a strong flattened tendon that inserts on the lateral surface of the greater trochanter. More specifically, the muscle's tendon inserts into an oblique ridge that runs downward and forward on the lateral surface of the greater trochanter.

After all, you’ve probably seen the countless workouts, diets, supplements, programs, products and people claiming that super fast muscle growth is possible. You’ve probably also seen the click-bait headlines (“How To Build 20lbs Of Muscle In Just 6 Weeks!”) and the unbelievable transformations of supposedly “natural” people (bodybuilders, celebrities, athletes, fitness gurus on social media, etc.) that clearly prove it can happen faster than this.

The specific mechanism of intestinal uptake for creatine is not clear, although transporters have been identified in rat jujenum, and confirmed at the mRNA level in humans.[129][130] The observation that creatine can be absorbed against a concentration gradient to a max ratio of 8:1 (8 times more creatine in the intestinal cell post absorption, relative to the lumen) supports transporter-mediated uptake, and the dependence on sodium and chloride implicate SLC6A8 (Creatine Transporter 1) as the operative transporter.[102]


If you have been struggling in the gym, getting over a plateau can seem very daunting. You are training hard, eating healthy, yet the results still aren’t coming. Creatine is a supplement which will help you gain strength, build muscle, lose fat, and give the energy you need to attack your workouts with an intensity that are guaranteed to give you results!
In fact, you could probably ride across Kansas (the pancake flat part anyway) while your butt muscles mostly snooze, explains kinesiologist Stuart McGill, Ph.D., Professor Emeritus at the University of Waterloo in Ontario, Canada, chief scientific officer at Backfitpro Inc., and author of Ultimate Back Fitness and Performance. “Typical cycling challenges the thighs—the quads and the hamstrings—but not really the gluteals,” he says. There are exceptions. “Sprinters use the glutes for acceleration. Hill climbers will use them when they’re out of the saddle. Otherwise, you will see most cyclists with hypertrophied [enlarged] legs, but the same could not be said for their glutes.”
How to do it: Balance on your right foot, keeping your midsection tight and shoulders back and down. Bend at the waist with both of your hands out to the sides and extend your left leg back as you fire the left glute. Your shoulder and heel should move together, forming a straight line. Return to starting position and switch legs, performing a set of 10 on each leg.
Bodybuilders may supplement their diets with protein for reasons of convenience, lower cost (relative to meat and fish products), ease of preparation, and to avoid the concurrent consumption of carbohydrates and fats. Additionally, some argue that bodybuilders, by virtue of their unique training and goals, require higher-than-average quantities of protein to support maximal muscle growth.[19][20][21][22][23][24][25] However, there is no scientific consensus for bodybuilders to consume more protein than the recommended dietary allowance.[18][26] Protein supplements are sold in ready-to-drink shakes, bars, meal replacement products (see below), bites, oats, gels and powders. Protein powders are the most popular and may have flavoring added for palatability. The powder is usually mixed with water, milk or fruit juice and is generally consumed immediately before and after exercising or in place of a meal. The sources of protein are as follows and differ in protein quality depending on their amino acid profile and digestibility:
Creatine also speeds recovery from exercise, enhancing adaptations such as strength and skeletal muscle hypertrophy. This has repeatedly been shown in teenagers, young adults, and the elderly alike. Accelerated recovery not only results from enhanced ATP restoration, for creatine also bolsters repletion of muscle carbohydrate stores, which may be related to protection against exercise-induced muscle damage. Such effects are especially germane to people undergoing short-term periods in which exercise training loads are substantially increased (“overreaching”).
Health-food stores sell creatine supplements in capsule, chewable, and powdered form, the most popular being the powder. One teaspoon of powder contains 5 grams (g) of creatine monohydrate. The recommended daily dose is 1-2 teaspoons dissolved in 8 ounces of water or sweetened beverage. Manufacturers and distributors suggest a five- to seven-day loading phase with intake of 10-20 g (2-4 scoops) daily to fill up the muscle. The maintenance phase of 5-10 g/day is recommended before and/or immediately following a workout. This protocol is claimed to increase creatine muscle stores by 20-50%.
Consuming sufficient high-quality protein is essential for building muscle. Current recommendations are to consume a minimum of 0.8g of protein for each kg of body weight, however, this is really only applicable to the average sedentary individual. Current evidence shows that to support muscle development, protein intake is the key, therefore the recommended 0.8g per kg should be increased to 1.5-2.0g of protein per kg of body weight. For an 80 kg individual, that would equate to 120-160 grams of protein per day.
Creatine is an energy substrate: a small peptide serving as a reservoir for high-energy phosphate groups that can regenerate ATP, the main currency of cellular energy. An increase in creatine intake (through food or supplementation) increases cellular energy stores, promoting the regeneration of ATP in the short term. Stores are limited, however, and glucose or fatty acids are responsible for ATP replenishment over longer durations.
As the name implies, the muscle power objective can be pursued if you want to achieve maximum size in your muscles or if you want them to be explosively strong (i.e. very powerful for short bursts at a time). In order to develop muscles this way you'll want to use no more than 3 sets in which no more than 8 reps are used. Muscle size and power is often used for muscles that are prominently displayed on the human figure, such as the pectorals, or the biceps and triceps.
Strong glutes also allow for movements such as bending over, squatting down, standing up straight, pushing off the ground (such as to run) and for maintaining other aspects related to proper posture. A 2005 report published in the Journal of Experimental Biology states that “The human gluteus maximus is a distinctive muscle in terms of size, anatomy and function compared to apes and other non-human primates …. Enlargement of the gluteus maximus was likely important in the evolution of hominid running capabilities.” (1)
Although weight training is similar to bodybuilding, they have different objectives. Bodybuilders use weight training to develop their muscles for size, shape, and symmetry regardless of any increase in strength for competition in bodybuilding contests; they train to maximize their muscular size and develop extremely low levels of body fat. In contrast, many weight trainers train to improve their strength and anaerobic endurance while not giving special attention to reducing body fat far below normal.

Most of us have lives, or jobs, or school, or family, or whatever else that puts some kind of limit on when and how often we can work out. For example, are there certain days that you are able to work out on, and certain days you aren’t? Are you able to train 5 days per week, or would 3-4 be more ideal? Choosing a split that suits your personal schedule and is as convenient for you as possible will be crucial for adherence, and without adherence, nothing is going to work.
Creatine supplementation has been noted to improve general wellbeing and health status (assessed by St George’s Respiratory questionnaire[582]) of people with COPD over two weeks loading (17.1g daily with carbohydrates) and ten weeks of 5.7g maintenance.[579] The studies that failed to find improvements with creatine supplementation on muscular performance also failed to find improvements in this rating scale, relative to placebo.[580][581]
The general strategy adopted by most present-day competitive bodybuilders is to make muscle gains for most of the year (known as the "off-season") and, approximately 12–14 weeks from competition, lose a maximum of body fat (referred to as "cutting") while preserving as much muscular mass as possible. The bulking phase entails remaining in a net positive energy balance (calorie surplus). The amount of a surplus in which a person remains is based on the person's goals, as a bigger surplus and longer bulking phase will create more fat tissue. The surplus of calories relative to one's energy balance will ensure that muscles remain in a state of anabolism.
The amount of testosterone synthesized is regulated by the hypothalamic–pituitary–testicular axis (see figure to the right).[133] When testosterone levels are low, gonadotropin-releasing hormone (GnRH) is released by the hypothalamus, which in turn stimulates the pituitary gland to release FSH and LH. These latter two hormones stimulate the testis to synthesize testosterone. Finally, increasing levels of testosterone through a negative feedback loop act on the hypothalamus and pituitary to inhibit the release of GnRH and FSH/LH, respectively.
Most weightlifters, athletes and bodybuilders know about creatine. They know it’s an important substance to take to give you an important edge in your workouts. Kaged Muscle made two different creatine products to give you the purest edge possible. They’re known as Kaged Muscle C-HCL Powder. There is a powder version and a capsule version. Keep Reading »

Creatine has demonstrated neuromuscular performance enhancing properties on short duration, predominantly anaerobic, intermittent exercises. Bazzucch et al [27] observed enhanced neuromuscular function of the elbow flexors in both electrically induced and voluntary contractions but not on endurance performance after 4 loading doses of 5 g creatine plus 15 g maltodextrin for 5/d in young, moderately trained men. Creatine supplementation may facilitate the reuptake of Ca2+ into the sacroplasmic reticulum by the action of the Ca2+ adenosine triphosphatase pump, which could enable force to be produced more rapidly through the faster detachment of the actomyosin bridges.
Low levels of testosterone in the body cause a number of symptoms including low sex drive, hair loss, fatigue, weakness, poor erection, loss of muscle mass, decreased bone mass, and infertility. However, low T can also cause emotional symptoms including depression, irritability, anxiety, mood changes, and sleep difficulty. Studies have shown, however, that depression does not affect only men. One study found that low T in women can also lead to depression. However, this is more common in post-menopausal women or women who are approaching the age of menopause.
Creatine is known to be present in the retina due to the expression of creatine kinase (CK)[466][39] and the GAMT enzyme of creatine synthesis, which is also present in the mammalian retina.[467] Creatine in the blood can be transported into the retina via the creatine transporter (confirmed in humans[468]), and inhibiting transporter activity (by depleting the medium of chloride and sodium) reduces uptake by 80%.[469] The fact that not all uptake was inhibited suggests that another transporter, such as the monocarboxylate transporter MCT12 (or SLC16A12),[470] plays a role, perhaps moreso in the lens, where its levels were comparable to that of the major creatine transporter SLC6A8.[470] 

Moreover, the Food and Drug Administration (FDA) has identified numerous products marketed as bodybuilding or muscle-building dietary supplements that contain hidden active ingredients, including prescription drugs and steroid and steroid-like ingredients. Not only do these ingredients pose serious health risks, they might cause you to pop positive on a drug test. The only way to be sure a product contains only what’s on the label is to look for one that has been evaluated by an independent, third-party organization. For more information, visit FDA’s Consumer Update about bodybuilding products.
Jason Ferruggia is a highly sought after, world renowned strength & conditioning specialist and muscle building expert. Over the last 17 years he has personally trained more than 700 athletes from over 90 different NCAA, NFL, NHL and MLB organizations. He has also worked extensively with firefighters, police officers, military personnel, Hollywood stars and entertainers. Most importantly, Jason has helped over 53,000 skinny guys and hard gainers in 126 different countries build muscle and gain weight faster than they every thought possible.
Beach muscles and Olympic lifts draw more attention. But the many little stabilizer muscles around your shoulders, hips, and midsection — collectively the core — provide a strong foundation. Challenging the stability and mobility of these key muscles with medicine balls, physioballs, mini-bands, and rotational movements (lifting, chopping) pays huge dividends.
Testosterone is the primary male sex hormone and an anabolic steroid. In male humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.[2] In addition, testosterone is involved in health and well-being,[3] and the prevention of osteoporosis.[4] Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss.
Creatine is vital for brain function, which has mechanisms to take up creatine, as well as regulate its intake. Although the diet appears to be the major source of creatine (and thus lack of dietary intake could cause a non-clinical deficiency) excess levels of creatine do not appear to “super-load” the brain similar to muscle tissue. Due to kinetics, creatine appears to be more “preventative” or acts to restore a deficiency in the brain. This is in contrast to creatine effects in muscle cells, where it can affect performance substantially on an acute timescale.
Weight training is primarily an isotonic form of exercise, as the force produced by the muscle to push or pull weighted objects should not change (though in practice the force produced does decrease as muscles fatigue). Any object can be used for weight training, but dumbbells, barbells, and other specialised equipment are normally used because they can be adjusted to specific weights and are easily gripped. Many exercises are not strictly isotonic because the force on the muscle varies as the joint moves through its range of motion. Movements can become easier or harder depending on the angle of muscular force relative to gravity; for example, a standard biceps curl becomes easier as the hand approaches the shoulder as more of the load is taken by the structure of the elbow. Originating from Nautilus, Inc., some machines use a logarithmic-spiral cam to keep resistance constant irrespective of the joint angle.

If you’re a beginner, you should train with three full-body workouts per week. In each one, do a compound pushing movement (like a bench press), a compound pulling movement (like a chinup), and a compound lower-body exercise (squat, trap-bar deadlift, for example). If you want to add in 1–2 other exercises like loaded carries or kettlebell swings as a finisher, that’s fine, but three exercises is enough to work the whole body.
Without supplementation, approximately 14.6mmol (2g) of creatinine, creatine’s urinary metabolite, is lost on a daily basis in a standard 70kg male ages 20-39. The value is slightly lower in females and the elderly due to a presence of less muscle mass.[35] This amount is considered necessary to obtain in either food or supplemental form to avoid creatine deficiency. Requirements may be increased in people with higher than normal lean mass.[35][198] Creatine excretion rates on a daily basis are correlated with muscle mass, and the value of 2g a day is derived from the aforementioned male population with about 120g creatine storage capacity.[35] Specifically, the rate of daily creatine losses is about 1.6%[199]-1.7%,[25] and mean losses for women are approximately 80% that of men due to less average lean mass.[35] For weight-matched elderly men (70kg, 70-79 years of age) the rate of loss of 7.8mmol/day,[49] or about half (53%) that of younger men.
For the sake of mental focus, it’s best to keep any carbs you eat low during the day when you’re working and active and get the lion’s share of them at night with dinner. A typical breakfast could include eggs, yogurt, and fruit, or a shake, and lunch could be meat or fish and steamed veggies. For dinner, have meat or fish again, along with sweet potatoes or rice, and vegetables.

Neurological and cognitive function has also been shown to be improved by creatine supplementation [47,48]. Rawson and Venezia [49] review the effects of creatine supplementation on cognitive function highlighting that higher brain creatine has been associated with improved neuropsychological performance. Creatine supplementation protocols have been shown to increase brain creatine and phosphocreatine contents. Cognitive processing hindered due to sleep deprivation and natural impairment due to aging can be improved by creatine supplementation. This review also highlights other possible benefits of creatine ingestion to older adults, such as improvements in: fatigue resistance, strength, muscle mass, bone mineral density, and performance of activities of daily living. Some of these benefits occur without concurrent exercise. The authors inform that discrepancies between studies do exist and are hard to explain but may be possibly due to differences in diet, race and/or supplementation protocols. However, the ideal dose of creatine to maximize brain uptake is not known. Patients have been supplemented with 40 g while in healthy adults positive results have been reported with around 20 g per day [49].
In males, testosterone is required for the development of male sex organs such as increased penis and testes size. The hormone also promotes the development of sexual male characteristics during puberty such as voice deepening and the growth of armpit, chest and pubic hair. Testosterone plays an important role in maintaining sex drive, sperm production, muscle strength and bone mass. A healthy level of testosterone is also protective against bone disorders such as osteoporosis.
You have to fuel your body with high-quality, real, wholesome food. Eating pizza, burgers, ice cream, and fast food just because it’s high in calories is a really bad plan. You’ll feel terrible, and while the extra calories will help muscle gains to an extent, most of them will turn to fat. It’s not worth it. Your recovery will be slower and you will be riddled with inflammation.

Creatine levels in the blood tend to return to baseline (after a loading with or without the maintenance phase) after 28 days without creatine supplementation.[152][200][201] This number may vary slightly from one individual to another, and for some may exceed 30 days.[202] Assuming an elimination rate of creatinine (creatine’s metabolite) at 14.6mmol per day,[35][201] six weeks of cessation is approaching the upper limit for serum creatine to completely return to baseline.
All muscles of the legs are more likely to become overused when repetitive movements are performed; this can be one behavior tied to overtraining, especially without proper rest or when not enough stretching is performed between workouts. Injuries of the gluteus maximus are most commonly due to repetitive movements of the legs that require motion in only one direction or plane.
Levels of testosterone naturally decrease with age, but exactly what level constitutes "low T," or hypogonadism, is controversial, Harvard Medical School said. Testosterone levels vary wildly, and can even differ depending on the time of day they're measured (levels tend to be lower in the evenings). The National Institutes of Health includes the following as possible symptoms of low testosterone:
Testosterone is significantly correlated with aggression and competitive behaviour and is directly facilitated by the latter. There are two theories on the role of testosterone in aggression and competition.[81] The first one is the challenge hypothesis which states that testosterone would increase during puberty thus facilitating reproductive and competitive behaviour which would include aggression.[81] Thus it is the challenge of competition among males of the species that facilitates aggression and violence.[81] Studies conducted have found direct correlation between testosterone and dominance especially among the most violent criminals in prison who had the highest testosterone levels.[81] The same research also found fathers (those outside competitive environments) had the lowest testosterone levels compared to other males.[81]

Bodybuilding became more popular in the 1950s and 1960s with the emergence of strength and gymnastics champions, and the simultaneous popularization of bodybuilding magazines, training principles, nutrition for bulking up and cutting down, the use of protein and other food supplements, and the opportunity to enter physique contests. The number of bodybuilding organizations grew, and most notably the International Federation of Bodybuilders (IFBB) was founded in 1946 by Canadian brothers Joe and Ben Weider. Other bodybuilding organizations included the Amateur Athletic Union (AAU), National Amateur Bodybuilding Association (NABBA), and the World Bodybuilding Guild (WBBG). Consequently, the male-dominated contests grew both in number and in size. Besides the many "Mr. XXX" (insert town, city, state, or region) championships, the most prestigious titles[according to whom?] were Mr. America, Mr. World, Mr. Universe, Mr. Galaxy, and ultimately Mr. Olympia, which was started in 1965 by the IFBB and is now considered the most important bodybuilding competition in the world.
Some of these medications that can harm the kidneys include cyclosporine (Neoral, Sandimmune); aminoglycosides including amikacin (Amikin), gentamicin (Garamycin, Gentak, others), and tobramycin (Nebcin, others); nonsteroidal anti-inflammatory drugs (NSAIDs) including ibuprofen (Advil, Motrin, Nuprin, others), indomethacin (Indocin), naproxen (Aleve, Anaprox, Naprelan, Naprosyn), piroxicam (Feldene); and numerous others.

Bench Press. The bench press is about as American as apple pie, fireworks, or bald eagles. If you’re in a gym on a Monday, then you can pretty guarantee at least 85% of the males in the building will be benching. With good reason though, variations such as the flat bench barbell or dumbbell press and the incline bench barbell or dumbbell press are very effective mass builders for the chest, shoulders, and triceps.

A proper warm-up is an important part of an effective strength workout. Start by foam rolling your muscles to wake 'em up. "Foam rolling loosens up tight muscles so that they work the way they're designed to," says Davis. A dynamic warm-up is another important part of your pre-workout routine, it preps your muscles for the work they're about to do and helps increase your range of motion. Increasing your range of motion allows you to go deeper into those squats and fully extend those bicep curls, which means more muscle recruitment and better results. "These two combined reduce your risk of injury and allow you to push harder during your workout," says Davis. Get started with this five-minute warm-up.

Testosterone is the principle sex hormone responsible for the development of reproductive function in male vertebrates. Testosterone is one of the hormones referred to as androgens, which are also known of as anabolic steroids. As a steroid hormone, testosterone is derived from cholesterol and the structure of this hormone is similar across all mammals, reptiles, birds and fish.
You may find this hard to believe, but some common breakfast foods like Kellogg’s corn flakes and Graham crackers were invented 100 years ago to lower male libido. Kellogg and Graham believed that male sexual desire was the root of society’s problems, so they set out to make bland foods that would take away libido (this is absolutely true; look it up). That low fat, grain-based thing absolutely works wonders for lowering testosterone.

In my late 20’s, I visited an anti-aging doctor who was one of the pioneers of what we now call functional medicine. I got a full hormone test. Shockingly, my testosterone was lower than my mother’s. No wonder I felt crappy and was overweight. My other sex hormones were out of whack too, especially my estrogen levels. They were high because the little testosterone I did make my body converted into estrogen. I went on a mix of topical replacement testosterone cream, plus small doses of pharmaceuticals like clomid and arimidex in order to keep my other sex hormones functioning properly.
Creatine citrate is creatine bound to citric acid, or citrate. Creatine citrate does not differ greatly from monohydrate in regard to absorption or kinetics.[83] Note that creatine citrate is more water-soluble than monohydrate,[84] but creatine absorption is generally not limited by solubility. The increased water solubility may play a factor in palatability.
For the bench press, start with a weight that you can lift comfortably. If you are a beginner, try lifting the bar along with 5lbs or 10lbs on each side. With arms at shoulder-width apart, grab onto the bar and slowly lower the bar until it's at nipple level; push up until your arms are fully extended upwards. Do 8–10 repetitions (reps) like this for three sets (3 x 8), adding additional weight each set. Once you have a few months of practice, slowly increase weight and go down to 6–8 reps per set, aiming to reach muscle failure at the end of the third set.
A typical creatine supplementation protocol of either a loading phase of 20 to 25 g CM/d or 0.3 g CM/kg/d split into 4 to 5 daily intakes of 5 g each have been recommended to quickly saturate creatine stores in the skeletal muscle. However a more moderate protocol where several smaller doses of creatine are ingested along the day (20 intakes of 1 g every 30 min) could be a better approach to get a maximal saturation of the intramuscular creatine store. In order to keep the maximal saturation of body creatine, the loading phase must be followed by a maintenance period of 3-5 g CM/d or 0.03 g CM/kg/d. These strategies appear to be the most efficient way of saturating the muscles and benefitting from CM supplementation. However more recent research has shown CM supplementation at doses of 0.1 g/kg body weight combined with resistance training improves training adaptations at a cellular and sub-cellular level. Creatine retention by the body from supplementation appears to be promoted by about 25% from the simultaneous ingestion of carbohydrate and/or protein mediated through an increase in insulin secretion. This combination would produce a faster saturation rate but has not been shown to have a greater effect on performance.
Bodybuilders may supplement their diets with protein for reasons of convenience, lower cost (relative to meat and fish products), ease of preparation, and to avoid the concurrent consumption of carbohydrates and fats. Additionally, some argue that bodybuilders, by virtue of their unique training and goals, require higher-than-average quantities of protein to support maximal muscle growth.[19][20][21][22][23][24][25] However, there is no scientific consensus for bodybuilders to consume more protein than the recommended dietary allowance.[18][26] Protein supplements are sold in ready-to-drink shakes, bars, meal replacement products (see below), bites, oats, gels and powders. Protein powders are the most popular and may have flavoring added for palatability. The powder is usually mixed with water, milk or fruit juice and is generally consumed immediately before and after exercising or in place of a meal. The sources of protein are as follows and differ in protein quality depending on their amino acid profile and digestibility:
The gluteus minimus is fan-shaped, arising from the outer surface of the ilium, between the anterior and inferior gluteal lines, and behind, from the margin of the greater sciatic notch. The fibers converge to the deep surface of a radiated aponeurosis, and this ends in a tendon which is inserted into an impression on the anterior border of the greater trochanter, and gives an expansion to the capsule of the hip joint.
Another supplement that’s ideal to take pre-workout is protein. Depending on your goals and your workout time, taking protein before your workout can help you keep your energy levels elevated while working out. Make sure you give yourself at least an hour between the time you take your protein and your workout time so that your body has time to digest.
Injections of creatine are known to be neuroprotective against low oxygen levels (hypoxia) even to neonatal rats.[532] This is thought to be associated with the increased collective pool of phosphocreatine and creatine.[236] Since oral ingestion of creatine by the mother increases brain concentrations of creatine by 3.6% in the fetus prior to birth,[531] it is thought to be protective in the fetuses subject to hypoxic (low oxygen) stressors, such as a caesarean section.
With a resistance band looped around your lower thighs, lay on your right side with your arm extended along the mat and your head relaxed on your arm. Bend both knees and draw them forward slightly to bring your feet in line with your glutes, ensuring that your hips are stacked and that you maintain a small gap between your waist and the floor. This is your starting position.

In standard dosages (5-10g creatine monohydrate) the bioavailability of creatine in humans is approximately 99%,[68][83] although this value is subject to change with different conjugates (forms) of creatine and dosages.[83] Coingestion of cyclocreatine (an analogue) can reduce uptake by about half[131] and coincubation of taurine, choline, glycine, or beta-alanine had minimal attenuation of absorption, which is likely not practically relevant.[131] The inhibition noted with cyclocreatine may be due to receptor saturation.


Creatine may preserve dopamine synthesis in the striatum of mice (while protecting against dopaminergic depletion) when fed to mice at 2% of the diet for one week prior to MPTP toxicity[230]. This is possibly secondary to increasing tyrosine hydroxylase activity, the rate-limiting step of dopamine biosynthesis.[210][235] Two percent creatine was as protective as 0.005% rofecoxib (a COX2 inhibitor), but the two were additive in their protective effects (highly synergistic in regard to DOPAC by normalizing it, but not synergistic in preserving HVA).[230]

Due to this relative deficiency-state in vegetarians and vegans, some aspects of creatine supplementation are seen as more akin to normalizing a deficiency, rather than providing the benefits of supplementation. In young vegetarians, but not omnivores, creatine supplementation can enhance cognition.[60][61] The increased gain in lean mass may be more significant in vegetarians, relative to omnivores.[59] Supplementation of creatine in vegetarians appears to normalize the gap in storage between vegetarians and omnivores.[62] This is possibly related to a correlation seen in survey research, where vegetarianism and veganism appear to be more commonly affected by some mental disorders like anxiety and depression.[63]


Beginners are advised to build up slowly to a weight training program. Untrained individuals may have some muscles that are comparatively stronger than others; nevertheless, an injury can result if (in a particular exercise) the primary muscle is stronger than its stabilizing muscles. Building up slowly allows muscles time to develop appropriate strengths relative to each other. This can also help to minimize delayed onset muscle soreness. A sudden start to an intense program can cause significant muscular soreness. Unexercised muscles contain cross-linkages that are torn during intense exercise. A regimen of flexibility exercises should be implemented before weight training begins, to help avoid soft tissue pain and injuries.
Creatine is not an essential nutrient[19] as it is naturally produced in the human body from the amino acids glycine and arginine, with an additional requirement for methionine to catalyze the transformation of guanidinoacetate to creatine. In the first step of the biosynthesis these two amino acids are combined by the enzyme arginine:glycine amidinotransferase (AGAT, EC:2.1.4.1) to form guanidinoacetate, which is then methylated by guanidinoacetate N-methyltransferase (GAMT, EC:2.1.1.2), using S-adenosyl methionine as the methyl donor. Creatine itself can be phosphorylated by creatine kinase to form phosphocreatine, which is used as an energy buffer in skeletal muscles and the brain.
Bodybuilders spend years and years of their lives focused on perfecting the human body through proper training and nutrition. You, on the other hand, might not have an interest in the sport of bodybuilding, but do want to know the secrets to six-pack abs, a wide back, and rounded shoulders. And what better place to score the tricks of the trade than from 3-time Mr. Olympia Phil Heath. 
Young adult athletes who reported creatine usage for over two years prior to the study (retrospective design) were not significantly different than controls.[501] Elsewhere, in a similar cohort of athletes reporting creatine usage for up to four years, failed to note significant differences in liver enzymes, although a nonsignificant reduction in LDH was noted.[502]
We hear this from 30 year olds and 60 year olds alike…and, like “I don’t have time,” it is a big fat lie! Even for the frail elderly, studies have shown that drastic results are possible in just 10 weeks of weightlifting (for both men and women in their 70s through their 90s). In fact, weight training has also been shown to delay Alzheimer’s and stave off dementia. So, if you think you might be “too old,” you’re probably the exact type of person that SHOULD be strength training!
In fact, most facilities offer special classes for seniors along with a knowledgeable staff that can guide you through proper exercise techniques. However, this 20-minute workout can be done anywhere, anytime. All you need is a light pair of dumbbells (3-5 pounds to start, 8-10 pounds as you get stronger) and a good pair of shoes and you’re ready to find the new active you! For best results, find a friend or partner to take this challenge on with you. You will keep each other accountable and safe while you get younger together!

Nutrient timing is a hot topic, especially for athletes and anyone looking for that extra edge in the gym or in body transformation. Part of this stems from science showing that the timing of carbohydrate consumption does influence important aspects, such as glycogen replenishment (and in limited cases, muscle protein synthesis). The other side is practical: You want the most bang for your buck when it comes to the nutritional products and supplements you purchase.
Prohormones are precursors to hormones and are most typically sold to bodybuilders as a precursor to the natural hormone testosterone. This conversion requires naturally occurring enzymes in the body. Side effects are not uncommon, as prohormones can also convert further into DHT and estrogen. To deal with this, many supplements also have aromatase inhibitors and DHT blockers such as chrysin and 4-androstene-3,6,17-trione. To date most prohormone products have not been thoroughly studied, and the health effects of prolonged use are unknown. Although initially available over the counter, their purchase was made illegal without a prescription in the US in 2004, and they hold similar status in many other countries. They remain legal, however, in the United Kingdom and the wider European Union. Their use is prohibited by most sporting bodies.
A: Depending upon your experience level, preference, recovery capacity, and time available, you’ll likely find that 3-5 strength training sessions per week is the sweet spot. If you’re just getting started with weight training, then you should stick with 3 days per week and work your way up. Novices and early intermediates can handle 4 days per week with a split such as an upper lower and seasoned intermediate lifters may be able to handle 5 sessions per week depending upon the programming, recovery, and nutrition strategies that are in place.
Free weights include dumbbells, barbells, medicine balls, sandbells, and kettlebells. Unlike weight machines, they do not constrain users to specific, fixed movements, and therefore require more effort from the individual's stabilizer muscles. It is often argued that free weight exercises are superior for precisely this reason. For example, they are recommended for golf players, since golf is a unilateral exercise that can break body balances, requiring exercises to keep the balance in muscles.[27]

The gluteus maximus arises from the posterior gluteal line of the inner upper ilium, and the rough portion of bone including the crest, immediately above and behind it; from the posterior surface of the lower part of the sacrum and the side of the coccyx; from the aponeurosis of the erector spinae (lumbodorsal fascia), the sacrotuberous ligament, and the fascia covering the gluteus medius. The fibers are directed obliquely downward and lateralward; The muscle has two insertions: Those forming the upper and larger portion of the muscle, together with the superficial fibers of the lower portion, end in a thick tendinous lamina, which passes across the greater trochanter, and inserts into the iliotibial band of the fascia lata; and the deeper fibers of the lower portion of the muscle are inserted into the gluteal tuberosity between the vastus lateralis and adductor magnus. Its action is to extend and to laterally rotate the hip, and also to extend the trunk.[citation needed]
Build an effective exercise routine. A good diet is required for your body to be able to maximize your potential, but there's no potential at all until you start the process of tearing down your old muscles and rebuilding them bigger, bulkier, and stronger. The best way to do that is to start at the beginning. If you're not sure where to begin, find a solid workout program online and try it out for a while. Don't immediately jump from one program to the next - you'll end up keeping yourself from making steady progress.

Although creatine supplementation has been shown to be more effective on predominantly anaerobic intermittent exercise, there is some evidence of its positive effects on endurance activities. Branch [28] highlights that endurance activities lasting more than 150s rely on oxidative phosphorylation as primary energy system supplier. From this meta analysis [28], it would appear that the ergogenic potential for creatine supplementation on predominantly aerobic endurance exercise diminishes as the duration of the activity increases over 150s. However it is suggested that creatine supplementation may cause a change in substrate utilization during aerobic activity possibly leading to an increase in steady state endurance performance.


It is prudent to note that creatine supplementation has been shown to reduce the body’s endogenous production of creatine, however levels return to normal after a brief period of time when supplementation ceases [1,6]. Despite this creatine supplementation has not been studied/supplemented with for a relatively long period. Due to this, long term effects are unknown, therefore safety cannot be guaranteed. Whilst the long term effects of creatine supplementation remain unclear, no definitive certainty of either a negative or a positive effect upon the body has been determined for many health professionals and national agencies [19,78]. For example the French Sanitary Agency has banned the buying of creatine due to the unproven allegation that a potential effect of creatine supplementation could be that of mutagenicity and carcinogenicity from the production of heterocyclic amines [78]. Long term and epidemiological data should continue to be produced and collected to determine the safety of creatine in all healthy individuals under all conditions [78].


This increased permeability is noted in glioma cells, where it exerts anti-cancer effects related to cell swelling,[99][100] and in other membranes, such as breast cancer cells[101] and skeletal (contractile) muscle cells.[102] The kinetics of cyclocreatine appear to be first-order,[101] with a relative Vmax of 90, Km of 25mM and a KD of 1.2mM.[103]
You see, there is only so much muscle that the human body is capable of building in a given period of time. So, if you supply your body with MORE calories than it’s actually capable of putting towards the process of building new muscle… it’s not going to magically lead to additional muscle being built. It’s just going to lead to additional fat being gained.
Stronger muscles improve performance in a variety of sports. Sport-specific training routines are used by many competitors. These often specify that the speed of muscle contraction during weight training should be the same as that of the particular sport. Sport-specific training routines also often include variations to both free weight and machine movements that may not be common for traditional weightlifting.

Don’t get us wrong—cardio is important for keeping your body fat down and keeping your heart health in check. (Bonus points if you run or bike, since outdoor exercise is linked to better energy and improved mental health.) But when it comes to building muscle, hitting the treadmill won't help you much. “Every component of exercise, minus cardio, can help with muscle hypertrophy,” which is the scientific term for muscle building, says Michelle Lovitt, an exercise physiologist and trainer in Los Angeles. “Cardio tends to burn calories and puts your body in a deficit, which is great for leaning out, but not building mass.”
These terms combine the prefix iso- (meaning "same") with tonic ("strength") and plio- ("more") with metric ("distance"). In "isotonic" exercises the force applied to the muscle does not change (while the length of the muscle decreases or increases) while in "plyometric" exercises the length of the muscle stretches and contracts rapidly to increase the power output of a muscle.
As the name implies, the muscle power objective can be pursued if you want to achieve maximum size in your muscles or if you want them to be explosively strong (i.e. very powerful for short bursts at a time). In order to develop muscles this way you'll want to use no more than 3 sets in which no more than 8 reps are used. Muscle size and power is often used for muscles that are prominently displayed on the human figure, such as the pectorals, or the biceps and triceps.
