Few supplements have the solid scientific foundation that creatine has. Studies show that it's effective for 80 percent of those who use it. Since creatine is found naturally in meat, the more meat you eat, the less likely you'll need creatine supplementation. Vegetarians or those who rarely eat meat, however, can get huge boosts from most creatine supplements.

Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than testosterone, so that its androgenic potency is about 5 times that of T.[118] The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.


It’s an amazing feeling when you graduate from lifting 10-pounders to 15-pounders. “Over time, you get better at something you’re doing, and you develop a sense of mastery and feeling that you’re getting stronger,” explains James Whitworth, a doctoral research fellow in the Biobehavioral Resistance Training Lab at Columbia’s Teachers College in New York City. “It helps your confidence, and that gives you a boost in self-esteem.”

It’s true—your genes can play a role when it comes to building muscle. In general, there are two types of muscle fibers: Type I, which are slow twitch, and Type II, which are fast twitch. Depending on which you have more of, you may have an easier or harder time gaining muscle. “Fast twitch muscle fibers are two times as thick as slow twitch muscle fibers, lending to the overall thickness of the muscle without any activity,” explains Lovitt. “Those people with a genetic predisposition of a high percentage of these fibers can increase muscle size very easily while the people with a higher percentage of slow twitch muscle fibers have to work really hard to put on mass.” It’s the reason why a world-class sprinter genetically has more fast twitch muscle fibers than a world-class marathoner—it comes down to what we’re born with.

A double-blind study provided 20 g/day of creatine monohydrate for 5 days to qualified sprinters and jumpers who performed 45 seconds of continuous jumping and 60 seconds of continuous treadmill running. Supplementation enhanced performance in the jumping test by 7% for the first 15 seconds and 12% for the next 15 seconds, but there was no difference for the final 15 seconds. There was a 13% improvement in the time of intensive running to exhaustion [12].
We’ll be talking more about this later, but for now, just give it a shot! In strength training you can see your progress so clearly that as you can do more and more, you’ll also be rewarded by seeing your strength progress from level 1 to level 50! If you aren’t a fan of the downtime, put on a book on tape or throw on your favorite playlist while circuit training to ensure you’re always moving (instead of sitting and waiting in between sets).

You’ll Feel Better: Not only will you find yourself with more energy and confidence, less stress and anxiety, and a better overall mood, but you’ll actually begin to think better (resistance training has been proven to help increase cognitive function). And while training too close to bedtime can be a bad idea, exercising earlier in the day has been proven to help prevent sleep apnea and insomnia. I even improved my posture – when I started lifting, I was 5’4”.  Now I’m 5’5.5”.

D-aspartic acid can also help to reduce cortisol levels. Cortisol is known as the “stress” hormone because its production increases during stressful situations. High cortisol levels can have many negative side effects, such as weight gain, muscle tissue breakdown, or increased blood sugar. Taking a supplement that includes cortisol can reduce stress and prevent excess fat storage or muscle loss.
Creatine concentration is normally increased in the placenta and brain in the midgestation phase until term, with further increases in the brain for another two weeks after birth.[529] This effect appears to be due to the fetus itself expressing the creatine enzymes of synthesis (AGAT and GAMT) after 5% of the gestation time has passed (0.9 days in spiny mice).[529] Despite creatine normally suppressing AGAT when supplemented at high concentrations,[29][30] it appears that maternal supplementation of the diet with 5% creatine from the halfway point of pregnancy until term does not alter creatine synthesis in the newborn (no alterations in either AGAT or GAMT), nor does it affect the creatine transporter.[530] 
Overload: The first thing you need to do to build lean muscle tissue is use more resistance than your muscles are used to. This is important because the more you do, the more your body is capable of doing, so you should increase your workload to avoid plateaus. In plain language, this means you should be lifting enough weight that you can only complete the desired number of reps. You should be able to finish your last rep with difficulty, but also with good form.
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.
Exercise is the original testosterone booster, and it’s one of the most powerful full-body hacks around. Men see a sharp increase in both testosterone and human growth hormone (HGH) after lifting weights, and the boost is greater with shorter rest time between sets (1 minute rest outperforms 3 minutes rest) [9]. With the shorter rest time, women also get a large boost in HGH.
Longer rest periods are more ideal for making progressive tension overload happen, and shorter rest periods are more ideal for generating metabolic fatigue. So, if you’re doing an exercise that is better suited for progressive overload (i.e. primary compound exercises), you’re going to want to rest longer between sets to maximize strength output. And if you’re doing an exercise that is better suited for metabolic fatigue (i.e. isolation exercises), you’re going to want to rest less between sets to make that happen. And if you’re doing an exercise that is suited equally for a combination of the two (i.e. secondary compound exercises), you’re usually going to want a moderate rest period somewhere in between.

Total levels of testosterone in the body are 264 to 916 ng/dL in men age 19 to 39 years,[169] while mean testosterone levels in adult men have been reported as 630 ng/dL.[170] Levels of testosterone in men decline with age.[169] In women, mean levels of total testosterone have been reported to be 32.6 ng/dL.[171][172] In women with hyperandrogenism, mean levels of total testosterone have been reported to be 62.1 ng/dL.[171][172]


Even if your focus is on a particular body part, say getting flat abs or losing fat around the hips, it's important to work all your muscle groups. Spot reduction doesn't work, so doing crunches for your abs or leg lifts for your thighs isn't going to help you achieve your goal. What does work is building more lean muscle tissue and burning more calories.

It also had a purpose. It turns out posing in powerful stances causes your testosterone to increase within 20 minutes [13,14]. In those two studies, power posing for just a few minutes also dropped cortisol and boosted confidence. It’s a great way to start your day, or to give yourself an edge before a job interview or a big presentation. They don’t call it “warrior pose” for nothing!


The structure of cyclocreatine is fairly flat (planar), which aids in passive diffusion across membranes. It has been used with success in an animal study, where mice suffered from a SLC6A8 (creatine transporter at the blood brain barrier) deficiency, which is not responsive to standard creatine supplementation.[97] This study failed to report increases in creatine stores in the brain, but noted a reduction of mental retardation associated with increased cyclocreatine and phosphorylated cyclocreatine storages.[97] As demonstrated by this animal study and previous ones, cyclocreatine is bioactive after oral ingestion[97][98] and may merely be a creatine mimetic, able to phosphorylate ADP via the creatine kinase system.[97]
“Imagine you've fasted for over eight hours,” he says. “At breakfast, you're firing your metabolism off really high. If you don't eat for another five hours, your metabolism starts to slow right down and you have to try and kickstart it again with your next meal. If you eat every two and a half to three hours, it's like chucking a log on a burning fire.”
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.
One of the studies noting a reduction in fatigue in healthy subjects given creatine (8g) for five days prior to a mathematical test noted a relative decrease in oxygenation hemoglobin in the brain and an increase in deoxygenated hemoglobin, which normally indicates a reduction in cerebral oxygenation.[245] The authors made note of how cytoplasmic phosphocreatine can increase oxygen uptake into cells (noted in vitro in a concentration dependent manner between 0-25mM[245]) and suggested that either cells were taking up more oxygen from hemoglobin, or that increased mitochondrial efficiency resulted in less of a need for oxygen.[245]
Although creatine is a natural component of food, the amount of food required to supersaturate the muscle with PCr may not be feasible. For example, it could require 22 pounds of meat daily [8]. If creatine monohydrate is proven to be a safe and effective ergogenic aid, creatine supplementation may be the simplest way to increasing muscle stores. It may be beneficial to avoid caffeine if taking creatine supplements. One study showed that caffeine diminished strength gains seen with creatine use [9].
There have also been concerns that creatine can cause kidney damage, and doctors warn that people with a history of kidney disease or conditions, such as diabetes, that increase the risk of kidney problems should steer clear of the supplement. Combining creatine with nephrotoxic drugs — drugs that might damage the kidneys — like nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (advil or motrin) and naproxen sodium (Aleve), should also be avoided, according to the U.S. Department of Health and Human Services.

As you've probably heard from any muscle-bound behemoth you've ever encountered, protein is the key to building muscle. Just because the shake-pounding meathead has become a trope, however, doesn't mean they're wrong; protein really is the fuel your muscles need to grow. That's real capital-S Science, not just bro-science manufactured by supplements companies.

Helping with running and other higher intensity activities that involve lift off — Some research has found that while the gluteus maximus supports lower levels of activity (like walking uphill or on an even surface) in certain ways, it’s strength is required much more for activities that require speed, such as jumping or running. In fact, some researchers believe that growth of the glutes in humans and other primates is tied to the evolution of running capabilities.
The body's pool of creatine can be replenished either from food (or supplements) or through synthesis from precursor amino acids. Dietary sources include beef, tuna, cod, salmon, herring, and pork [2]. The normal dietary intake of creatine is 1-2 g/day, although vegetarians may consume less [3,4]. Dietary creatine is absorbed from the intestines into the bloodstream. If the dietary supply is limited, creatine can be synthesized from the body stores of the amino acids glycine, arginine, and methionine. The kidneys use glycine and arginine to make guanidinoacetate, which the liver methylates to form creatine [1], which is transported to the muscle cells for storage. It is also stored in the kidneys, sperm cells, and brain tissue [5].
“Compared to training for strength, intensity is going to drop during the hypertrophy phase of a program, with intensity sitting between 50 and 75 percent of the person’s 1RM, the maximum weight he or she can lift for one rep,” says Ava Fitzgerald, C.S.C.S., C.P.T., a sports performance coach with the Professional Athletic Performance Center in New York.
A study using creatine at 0.02% of a face cream (confounded with 8% glycerol and 0.4% Guarana) was able to exert a skin-tightening effect over 6 weeks, reducing wrinkles and jowl volume.[541] Combination therapy has also been used with creatine and folic acid (both in vitro[543] and in vivo), resulting in increased skin firmness and reduced coarse and fine wrinkles.[544]
Lie on your left side and position yourself so that your bottom forearm is directly under your armpit and your legs are straight with feet stacked. Brace your core and lift your hips in the air, forming a straight line from ankles to shoulders. Next, raise your top leg, without bending your knee, a few inches into the air. Hold for 3-5 seconds, lower the leg, and repeat. Complete required reps then switch sides.

While I’m not well-versed in DNP, it is important to note that most supplements are not regulated by the FDA. The FDA has minimal standards for governing supplements before they make it to the shelves. All supplementation should be a case-by-case basis and under the discretion of a doctor and/or registered dietitian who knows your personal needs. Also, if you are consuming a well-rounded, healthy diet, supplementation may not be needed, even for making gains at the gym.
Back in the 1970s, scientists discovered that taking creatine in supplement form might enhance physical performance. In the 1990s, athletes started to catch on, and creatine became a popular sports supplement. The supplement is particularly popular among high school, college, and professional athletes, especially football and hockey players, wrestlers, and gymnasts. 
In addition to the HIIT sessions, it’s always a good idea to go for a 30–60-minute walk as many days per week as you can. I recommend getting a minimum of 10,000 steps every day. Use a phone app to track them. If you’re into jogging, swimming, hiking, or some other form of long-duration, fairly low-intensity cardio, that is fine to do as well, and as often as you like.
The pancreas is one of the extrahepatic (beyond the liver) organs that can synthesize creatine, alongside the kidneys.[486][487] Freshly prepared pancreatic β-cells will normally secrete insulin in response to glucose stimulation, and it appears that phosphocreatine is required for this effect, since phosphocreatine is increased in response to glucose[488] alongside an increase of the ADP:ATP ratio. They appear to close ATP sensitive potassium channels (KATP channels), causing a release of insulin secondary to calcium release.[488] Both phosphocreatine[488] and ADP[489] are implicated, but it seems that despite the channel being sensitive to ATP,[490] the concentration of ATP in a pancreatic cell (3-5mM[491][492]) is already above the activation threshold (in the micromolar range[493]) and thus a further increase would not have an appreciable effect.
The main consequence to using weight training exercises is the increase in muscle strength that you'll develop over time. You'll also develop stronger bones as well as gain a better general posture. In short, maintaining good muscle strength will allow your body to move more freely from the moment you wake up in the morning to the moment you fall asleep at night.
Yes, genetically some of us put on muscle faster than others, but even then it’s fractions of a degree, not DRASTIC sweeping differences. We tend to get this question from men or women who are so thin and have such fast metabolisms, they probably need to put on 40-50+ pounds of both fat and muscle, before they would ever even think to use the word “too bulky.”
A study showed that 100mg/kg creatine monohydrate daily over four months supplemented by boys with DMD is able to enhance handgrip strength in the dominant hand only (less than 10% increase) and increase whole-body lean mass. While the trend toward whole body strength reduction seen in placebo was ablated and there was no interaction with corticosteroids,[560] this study failed to find an influence on activities of daily living or lung function.[560] Elsewhere in children not on corticosteroids with DMD, supplementation of 5g creatine for eight weeks was confirmed to increase muscular phosphocreatine content[554] and according to a manual muscle test (MMT) there was a significant improvement in muscular function relative to placebo, with more parents reporting benefit with creatine (53.8%) relative to placebo (14%).[554]

Though weight training can stimulate the cardiovascular system, many exercise physiologists, based on their observation of maximal oxygen uptake, argue that aerobics training is a better cardiovascular stimulus. Central catheter monitoring during resistance training reveals increased cardiac output, suggesting that strength training shows potential for cardiovascular exercise. However, a 2007 meta-analysis found that, though aerobic training is an effective therapy for heart failure patients, combined aerobic and strength training is ineffective; "the favorable antiremodeling role of aerobic exercise was not confirmed when this mode of exercise was combined with strength training".[36]


There are countless reasons to lift weights and build strong muscles, including injury prevention, improved bone density, and a lower risk for type 2 diabetes and other diseases—not to forget that bad-ass feeling you get when you can haul a giant piece of furniture up the stairs all by yourself. Another often-cited benefit to strength training is that it will increase your metabolism. But how much does your metabolism increase with strength training? The answer depends on many different factors.
One case study exists of a man with focal segmental glomerulosclerosis who experienced an accelerated rate of GFR decline during supplementation (5g thrice daily for loading, then a 2g maintenance for seven weeks) which was partially reversed upon supplement cessation. This was deemed strong circumstantial evidence, and the brand of supplement was not named.[616] Elsewhere, interstitial nephritis associated with creatine supplementation has been reported in a man, although symptoms arose four weeks after supplementation started with no evidence to support correlation.[617] Some studies involving athletes and various dietary supplements have attempted to draw a correlation with creatine and cases of rhabdomyolysis.[618][619][620][621] Finally, one study in a diabetic person ingesting both metformin and creatine resulting in metabolic acidosis has attempted to place causation on creatine, but it did not establish causation or circumstantial evidence.[622]

Jager et al [60] observed 1.17 and 1.29 greater peak plasma creatine concentration 1 hour after ingesting creatine pyruvate compared to isomolar amount of CM and creatine citrate respectively. However time to peak concentration, and velocity constants of absorption and elimination, was the same for all three forms of creatine. Although not measured in this study it is questionable that these small differences in plasma creatine concentrations would have any effect on the increase of muscle creatine uptake. Jäger et al [61] investigated the effects of 28-days of creatine pyruvate and citrate supplementation on endurance capacity and power measured during an intermittent handgrip (15 s effort per 45s rest) exercise in healthy young athletes. The authors used a daily dose protocol with the intention to slowly saturate muscle creatine stores. Both forms of creatine showed slightly different effects on plasma creatine absorption and kinetics. The two creatine salts significantly increased mean power but only pyruvate forms showed significant effects for increasing force and attenuating fatigability during all intervals. These effects can be attributed to an enhanced contraction and relaxation velocity as well as a higher blood flow and muscle oxygen uptake. On the other hand, the power performance measured with the citrate forms decreases with time and improvements were not significant during the later intervals. In spite of these positive trends further research is required about the effects of these forms of creatine as there is little or no evidence for their safety and efficacy. Furthermore the regularity status of the novel forms of creatine vary from country to country and are often found to be unclear when compared to that of CM [62].

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.

It is possible that females could benefit more than males due to a combined lower creatine kinase activity as well as having altered purine metabolism during depression,[257] but no human comparative studies have been conducted yet. One rat study noted that creatine monohydrate at 2-4% of feed had 4% creatine able to exert anti-depressive and anxiolytic effects in female rats only.[228]
Another double-blind study supplemented with 18.75 g/day of creatine monohydrate for 5 days prior to high-intensity intermittent work to exhaustion, and then 2.25 g/day during testing. The workouts consisted of cycling to exhaustion using several protocols: (a) nonstop, (b) 60 seconds work/120 seconds rest, (c) 20 seconds work/40 seconds rest, and (d) 10 seconds work/20 seconds rest. Creatine supplementation significantly increased the total work time for all four protocols [13].
Older women with knee osteoarthritis given supplemental creatine at 20g for five days followed by 5g for the rest of the twelve week trial experienced improvements in stiffness (52% reduction), pain (45%), and physical function (41%) as assessed by WOMAC, despite no improvements in physical power output relative to placebo.[425] This study paired supplementation and placebo with a mild exercise regimen.[425]
A great analogy that I like is that the balance between training and recovery is like digging a hole. Each time you lift, you dig yourself deeper and make it harder to climb out of the hole. To get back out again, you have to fill in the hole to return to ground level, and the only way to fill it is with food and rest. If you overdo it in the gym by pushing too hard, you won’t be able to train as often or at a high capacity. Eventually, you’ll get injured. 

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.

You’d have to look hard to find a fitness expert who doesn’t recommend taking supplemental protein powder for building muscle. It’s one of the best supplements for building muscle on the market! In addition to serving as a muscle building supplement, protein powder can be the perfect complement to a successful weight loss plan. Studies show that the supplement can prevent loss of muscle mass, helping you lose fat exclusively instead.
Creatine monohydrate is regarded as a necessity by most bodybuilders. Creatine monohydrate is the most cost-effective dietary supplement in terms of muscle size and strength gains. … There is no preferred creatine supplement, but it is believed that creatine works best when it is consumed with simple carbohydrates. This can be accomplished by mixing powdered creatine with grape juice, lemonade, or many high glycemic index drinks.[36]
Testosterone is included in the World Health Organization's list of essential medicines, which are the most important medications needed in a basic health system.[111] It is available as a generic medication.[10] The price depends on the form of testosterone used.[112] It can be administered as a cream or transdermal patch that is applied to the skin, by injection into a muscle, as a tablet that is placed in the cheek, or by ingestion.[10]

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.

Carbohydrates play an important role for bodybuilders. They give the body energy to deal with the rigors of training and recovery. Carbohydrates also promote secretion of insulin, a hormone enabling cells to get the glucose they need. Insulin also carries amino acids into cells and promotes protein synthesis.[26] Insulin has steroid-like effects in terms of muscle gains.[27] It is impossible to promote protein synthesis without the existence of insulin, which means that without ingesting carbohydrates or protein—which also induces the release of insulin—it is impossible to add muscle mass.[28] Bodybuilders seek out low-glycemic polysaccharides and other slowly digesting carbohydrates, which release energy in a more stable fashion than high-glycemic sugars and starches. This is important as high-glycemic carbohydrates cause a sharp insulin response, which places the body in a state where it is likely to store additional food energy as fat. However, bodybuilders frequently do ingest some quickly digesting sugars (often in form of pure dextrose or maltodextrin) just before, during, and/or just after a workout. This may help to replenish glycogen stored within the muscle, and to stimulate muscle protein synthesis.[29]
Any type of running will help strengthen your glutes, but sprinting at a very fast speed is even more effective. You can perform sprints as part of a HIIT workout or simply increase your speed while running or briskly walking for a short distance. Start out with about 15–20 minutes of HIIT intervals and work your way up to 25–30 minutes if you’d like.  To perform intervals alternate slower running or resting for 1–2 minutes with 30–90 seconds of sprinting as fast as you can. Most experts recommend practicing HIIT workouts 2–3 times per week.
Hypogonadism (as well as age-related low testosterone) is diagnosed with blood tests that measure the level of testosterone in the body. The Endocrine Society recommends testing for suspected low T with a total testosterone test. It may be performed in the morning when testosterone levels tend to be highest in young men, although this isn't necessarily the case in older men. The test may be repeated on another day if the results show a low T level. (5)

For many people, appearance is the top priority when it comes to their posterior. But yoga practitioners also know that the glute muscles can do so much more than look great in jeans: They’re the primary players in many of the movements that make it possible to do yoga. The gluteus maximus, medius, and minimus—along with many other smaller, supporting muscles—act as a base of support for the pelvis and hips. What’s more, these hard-working muscles stabilize your femur (thighbone) in your hip socket, rotate your femur internally and externally, and draw your leg back. And yes, all of these actions also help us stand and walk, and even support us when we sit.
The rise in testosterone levels during competition predicted aggression in males but not in females.[90] Subjects who interacted with hand guns and an experimental game showed rise in testosterone and aggression.[91] Natural selection might have evolved males to be more sensitive to competitive and status challenge situations and that the interacting roles of testosterone are the essential ingredient for aggressive behaviour in these situations.[92] Testosterone produces aggression by activating subcortical areas in the brain, which may also be inhibited or suppressed by social norms or familial situations while still manifesting in diverse intensities and ways through thoughts, anger, verbal aggression, competition, dominance and physical violence.[93] Testosterone mediates attraction to cruel and violent cues in men by promoting extended viewing of violent stimuli.[94] Testosterone specific structural brain characteristic can predict aggressive behaviour in individuals.[95]
That pump is tangible, real-time biofeedback to let you know that blood is flowing to your muscle cells, beginning a chain of events that stimulates protein synthesis. Maybe that'’s why it's easy to overlook how important good nutrition is in the mass-building equation. When you choose to eat, say, chicken instead of ice cream, there'’s no immediate muscle gratification -- no pump to keep you motivated.

Homocysteine is an endogenous metabolite involved in methylation processes in the body. Mildly elevated homocysteine appears to be an independent risk factor for both cardiovascular[302] and atherosclerotic disease,[303] where if the 8-10μM normal range is elevated by around 5μM, it is thought to confer 60-80% greater risk of atherosclerotic disease[303]. Although it may not independently cause problems,[304] it may play a causative role in the context of the whole body system, since it is atherogenic by augmenting LDL oxidation[305] and promoting conversion of macrophages into foam cells.[306]
I know this goes against the recommendations you often see in stereotypical bodybuilding routines (i.e. the ones that involve having a single “chest day” or “arm day” or “shoulder day” once a week), but that’s just one of the many reasons why those types of routines suck for us natural, genetically-average people, and work best for steroid users with great genetics.
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.
Related to exercise and fitness, BCAAs are taken to help reduce muscle breakdown, which is why they may be known as muscle building supplements. Leucine, in particular, is known for playing an important role in muscle protein synthesis, which can help with muscle gain and maintenance. Some also claim that BCAAs can enhance performance, although many studies also refute this claim.
In addition to its role as a natural hormone, testosterone is used as a medication, for instance in the treatment of low testosterone levels in men and breast cancer in women.[10] Since testosterone levels decrease as men age, testosterone is sometimes used in older men to counteract this deficiency. It is also used illicitly to enhance physique and performance, for instance in athletes.

An isolation exercise is one where the movement is restricted to one joint only. For example, the leg extension is an isolation exercise for the quadriceps. Specialized types of equipment are used to ensure that other muscle groups are only minimally involved—they just help the individual maintain a stable posture—and movement occurs only around the knee joint. Most isolation exercises involve machines rather than dumbbells and barbells (free weights), though free weights can be used when combined with special positions and joint bracing.

The slider reverse lunge is simple to perform and doesn’t need much in the way of instructions. Simply grab a Valslide, or a similar tool that will allow you to move smoothly across the ground. Put the slide under one foot, and use that foot to slide into a reverse lunge, and then return to standing. Try doing this exercise after one of the ones above, and just wait until you feel the burn!
I'm 6'1" 175 pounds 27 years old. I would like to increase my general muscle mass and reduce my stomach fat. I would consider myself and ectomorph (hard gainer) as I have never really developed much muscle while I've always been very active in sports and periodic weight training. Over the past year I lost about 30 pounds (nearly all fat) by reducing my caloric intake effectively and regular whole body exercises. I was on my way to my ideal body composition until I became a bike courier. I've been a bike messenger for 9 months and recently my stomach fat has started to return. I'm riding 50+ miles each weekday riding for 9 hours a day. How many calories should I be eating? I've tried everywhere between 2400-3,500 cal/day. Is it possible for me to be eating too few calories while still accumulating stomach fat? Is it realistic for me to be able to maintain or even build muscle mass in this scenario? Please help, thanks.
In young rats given creatine in the diet at 2% of the diet for eight weeks, supplementation appears to increase bone mineral density (BMD) in the lumbar spine with a nonsignificant trend to increase BMD in the femur.[426] Despite the trend, the femur appeared to be 12.3% more resistant to snapping from mechanical stress associated with increased thickness.[426] Menopausal rats (ovarectomized) experience similar benefits, as supplementation of creatine (300mg/kg) for eight weeks during ovarectomy is able to increase phosphorus content of the bone and other biomarkers of bone health, although bone stress resistance was not tested.[427]
Homocysteine is produced after S-adenosyl methionine is used up (as donating a methyl group creates S-adenosylhomocysteine, which then produces homocysteine) mostly from phosphatidylcholine synthesis[307] and its reduction (via either methylation from trimethylglycine via betaine:homocysteine methyltransferase, urinary excretion, or convertion into L-cysteine via cystathionine beta-synthase[308]) is thought to be therapeutic for cardiovascular diseases.
In addition to conjugation and the 17-ketosteroid pathway, testosterone can also be hydroxylated and oxidized in the liver by cytochrome P450 enzymes, including CYP3A4, CYP3A5, CYP2C9, CYP2C19, and CYP2D6.[159] 6β-Hydroxylation and to a lesser extent 16β-hydroxylation are the major transformations.[159] The 6β-hydroxylation of testosterone is catalyzed mainly by CYP3A4 and to a lesser extent CYP3A5 and is responsible for 75 to 80% of cytochrome P450-mediated testosterone metabolism.[159] In addition to 6β- and 16β-hydroxytestosterone, 1β-, 2α/β-, 11β-, and 15β-hydroxytestosterone are also formed as minor metabolites.[159][160] Certain cytochrome P450 enzymes such as CYP2C9 and CYP2C19 can also oxidize testosterone at the C17 position to form androstenedione.[159]

When females have a higher baseline level of testosterone, they have higher increases in sexual arousal levels but smaller increases in testosterone, indicating a ceiling effect on testosterone levels in females. Sexual thoughts also change the level of testosterone but not level of cortisol in the female body, and hormonal contraceptives may affect the variation in testosterone response to sexual thoughts.[51]
While creatine's influence on physical performance has been well documented since the early twentieth century, it came into public view following the 1992 Olympics in Barcelona. An August 7, 1992 article in The Times reported that Linford Christie, the gold medal winner at 100 meters, had used creatine before the Olympics. An article in Bodybuilding Monthly named Sally Gunnell, who was the gold medalist in the 400-meter hurdles, as another creatine user. In addition, The Times also noted that 100 meter hurdler Colin Jackson began taking creatine before the Olympics.[12][13]
One case study exists of a man with focal segmental glomerulosclerosis who experienced an accelerated rate of GFR decline during supplementation (5g thrice daily for loading, then a 2g maintenance for seven weeks) which was partially reversed upon supplement cessation. This was deemed strong circumstantial evidence, and the brand of supplement was not named.[616] Elsewhere, interstitial nephritis associated with creatine supplementation has been reported in a man, although symptoms arose four weeks after supplementation started with no evidence to support correlation.[617] Some studies involving athletes and various dietary supplements have attempted to draw a correlation with creatine and cases of rhabdomyolysis.[618][619][620][621] Finally, one study in a diabetic person ingesting both metformin and creatine resulting in metabolic acidosis has attempted to place causation on creatine, but it did not establish causation or circumstantial evidence.[622]
Recently, studies are coming out that show a general decline in testosterone levels of men in the United States and around the world. The trend is across the board and doesn’t appear to be caused simply by a decline in health, aging or an increase in obesity rates. It could be caused because of chemicals or environmental factors. In any case, low levels of testosterone can affect many areas of your health, including your ability to build muscle. If you suspect that you have low testosterone levels, you can ask your doctor to test you for it. In addition to traditional hormone therapies, there are also many natural ways to boost your levels including through supplements, some of which will be discussed later in this article.

It’s not just about lifting—it’s about lifting safely and correctly. And if you’re not performing exercises properly, it’s impossible to make any progress. “When someone is just starting to work out, it can help to work closely with a knowledgeable personal trainer in order to learn proper form,” says Ingram. But that goes for experienced lifters, too. If you aren’t sure about a movement, it’s better to ask. “If you’re not working the correct muscles, you can’t expect them to grow,” explains Ingram.

You've got your equipment ready, now it's time to choose about eight to 10 exercises, which comes out to about one exercise per muscle group. Use the list below to choose at least one exercise per muscle group to start. For the larger muscles, like the chest, back, and legs, you can usually do more than one exercise. These involve a variety of equipment, so you can choose based on what you have available.

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.
2. What's your training like? Are you crushing 25 sets for chest like the average juiced out bodybuilder? If so, there's a pretty good chance you might be working above your MRV (maximal recoverable volume) and as such any physiological adaptation which could have taken place is going to be minimal given the cellular environment which occurs in a state of functional overreaching.

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.


For the best results, do the glute exercises and stretches listed below about three to four times per week. You can either aim for a specific number of reps (such as 10–20 reps per set, depending on your fitness level) or do the exercises in a circuit, performing each exercise for 45–60 seconds with a 15-second break between. For beginners, perform two sets or two rounds in total. And for advanced exercisers aim, for three to four sets/rounds in total.
