How long and how often? Two or three weekly 20- to 30-minute, weight-training sessions are sufficient to start reaping noticeable benefits within four to 12 weeks, such as improved energy and muscle tone. Within six months, most people increase their strength 40 percent or more. Give your body at least one recovery day between sessions (although some people may need more, especially in the beginning).

In patients with DM1 given a short loading phase (10.6g for ten days) followed by a 5.3g maintenance for the remainder of an 8-week trial noted that supplementation resulted in a minor improvement in strength (statistical significance only occurred since placebo deteriorated) and no significant difference was noted in self-reported perceived benefits.[565] Maintaining a 5g dosage for four months also failed to significantly improve physical performance (handgrip strength and functional tests) in people with DM1, possible related to a failure to increase muscular phosphocreatine concentrations.[566]
A child’s ability to regenerate high energy phosphates during high intensity exercise is less than that of an adult. Due to this, creatine supplementation may benefit the rate and use of creatine phosphate and ATP rephosporylation. However, performance in short duration high-intensity exercise can be improved through training therefore supplementation may not be necessary [54].

Children: Creatine is POSSIBLY SAFE in children when taken by mouth appropriately. Creatine 3-5 grams daily for 2-6 months has been taken safely in children 5-18 years of age. Creatine 2 grams daily for 6 months has been taken safely in children 2-5 years of age. Additionally, creatine 0.1-0.4 grams/kg daily for up to 6 months has been taken safely in both infants and children.
Makes You Healthier: If you’re looking for a workout in which you get the biggest bang for your buck, strength training is it. Strength training increases bone density, builds a stronger heart, reduces your resting blood pressure, improves blood flow, halts muscle loss, helps control blood sugar, improves cholesterol levels, and improves your balance and coordination (turning you from this, to this).

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.”

When it comes to training, I prefer to stick with the basics. People think they need 10 different exercises to fashion a fine pair of cheeks, but that's not what it takes. When it comes to toning your glutes, you only need two things: drive and dedication—and I mean real dedication. You must train your glutes hard and diligently to get a great response. If you stop every time it gets difficult or whenever it burns, you're not going to get anywhere.
Do standard squats with a weighted bar. Place enough weight on a bar and rack so that it's a little lower than shoulder height. It should be heavy enough that doing a squat is difficult, but not impossible. If you're a beginner, this may mean using a bar without any weight to start with. Duck under the bar and stand up so that the bar rests comfortably on your trapezius muscles, just below the neck. Keep your knees slightly bent and your legs slightly wider than shoulder width. Lift the bar up off the rack and move backwards one step.
While some supplements may in fact provide health benefits, generally speaking, consumers should purchase and use these products cautiously as they are not closely regulated by the Food and Drug Administration (FDA). Also, bodybuilders are advised to discuss supplementation plans with a registered dietitian or primary care physician prior to use to optimize effectiveness and minimize potential harmful consequences. 
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 bulking and cutting strategy is effective because there is a well-established link between muscle hypertrophy and being in a state of positive energy balance.[19] A sustained period of caloric surplus will allow the athlete to gain more fat-free mass than they could otherwise gain under eucaloric conditions. Some gain in fat mass is expected, which athletes seek to oxidize in a cutting period while maintaining as much lean mass as possible.
I get lost every time I walk into my neighborhood GNC… the people who work there know their stuff, but nobody knows my body better than me and that’s where it all falls apart, but I’m working on that. I agree, I rather have grass-fed and more natural options as opposed to anything containing GMO in the products… The point is to become healthier, not go the other way…. But I also don’t want to get too much soy in my diet either… My wife is doesn’t want it for me and it’s given me headaches too, so I’m not really one for those. I guess small amounts of soy should be okay, right? Could someone be allergic to soy? There’s tons of other options though and I’m going to have to really look more into these here coz it has everything I’ve been looking for! Thanks for putting this together!

This amino acid is actually produced by your body and so is considered a non-essential amino acid. However, in addition to taking it in supplement form, beta-alanine is also found in protein-heavy foods like meat and fish (9). This amino acid has been linked to performance enhancement outcomes, especially for weightlifters. Studies show increased performance when taking this supplement.

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] 
A loading phase of 10g creatine monohydrate for two weeks and 4g for the final week in subjects with MELAS (Mitochondrial Encephalomyopathy Lactic Acidosis and Stroke-like episodes) has been noted to increase physical strength relative to baseline, although the poor VO2 max seen in these subjects was not affected.[549] A case study exists in which a patient with a relatively novel mutation in their mitochondrial function (affecting cytochrome B) experienced benefits from creatine at 10g daily.[550] Researchers examining another case of MELAS found both cognitive and physical benefits with 5g creatine supplementation,[551] while four controlled case studies of 100-200mg/kg daily in children with myopathies found improved muscular endurance (30-57%) and muscular power (8-17%) after 100-200mg/kg daily for at least three months.[552]
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.
In addition to the proper amount of sleep, do not overdo your training regimen. While you might be tempted to think that "more is better," in fact the opposite is true. You can reach a point known as "over-training", in which you'll lose the ability to "pump" (engorge the muscles with oxygen-rich blood) your muscles, and this can even lead to muscle wasting—exactly the opposite of what you are trying to achieve. Here are some symptoms to be aware of if you think you may be falling into the over-training zone:
^ Southren AL, Gordon GG, Tochimoto S, Pinzon G, Lane DR, Stypulkowski W (May 1967). "Mean plasma concentration, metabolic clearance and basal plasma production rates of testosterone in normal young men and women using a constant infusion procedure: effect of time of day and plasma concentration on the metabolic clearance rate of testosterone".

Women who train hard and reach low body fat levels, say under 10 percent, may be at risk of losing their periods as a result of hormonal disruption to estrogen production. Exercise-induced estrogen declines can result in bone loss in a way similar to that which occurs at the menopause. Loss of periods from athletic training is not uncommon but does require that you see a doctor, or better still, a sports physician and sports nutritionist to assess what is required to address the problem. Calcium supplements may be a part of the solution if bone health is likely to be affected. 

Both testosterone and 5α-DHT are metabolized mainly in the liver.[1][155] Approximately 50% of testosterone is metabolized via conjugation into testosterone glucuronide and to a lesser extent testosterone sulfate by glucuronosyltransferases and sulfotransferases, respectively.[1] An additional 40% of testosterone is metabolized in equal proportions into the 17-ketosteroids androsterone and etiocholanolone via the combined actions of 5α- and 5β-reductases, 3α-hydroxysteroid dehydrogenase, and 17β-HSD, in that order.[1][155][156] Androsterone and etiocholanolone are then glucuronidated and to a lesser extent sulfated similarly to testosterone.[1][155] The conjugates of testosterone and its hepatic metabolites are released from the liver into circulation and excreted in the urine and bile.[1][155][156] Only a small fraction (2%) of testosterone is excreted unchanged in the urine.[155]
Contrast loading is the alternation of heavy and light loads. Considered as sets, the heavy load is performed at about 85-95% 1 repetition max; the light load should be considerably lighter at about 30-60% 1RM. Both sets should be performed fast with the lighter set being performed as fast as possible. The joints should not be locked as this inhibits muscle fibre recruitment and reduces the speed at which the exercise can be performed. The lighter set may be a loaded plyometric exercise such as loaded squat jumps or jumps with a trap bar.
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].
Even if you have a schedule that allows for a 5-day workout split, many people (I’d even call it the majority) simply don’t have the recovery capacity needed to make that work. This could be due to genetics, age, injury history, various lifestyle factors (sleep, stress, etc.) and more. In these cases, better results would be seen with 3-4 workouts per week instead.
In the following article I will outline the supplements that have helped me to add a massive 10 kilograms (22lbs) of solid muscle to my physique over the past year—taking my body weight from 80 kilograms (176lbs) to 90 kilograms (198lbs)—and explain how these have helped me to improve my performance and enhance my size as a natural bodybuilder, aged 35.

In otherwise sedentary and healthy men given a loading phase of creatine followed by 11 weeks of maintenance, the glucose response to an oral glucose tolerance test is reduced by 11-22% (measurements at 4-12 weeks with no time dependence noted) which was not associated with changes in insulin levels or sensitivity.[350] Elsewhere, a study in vegetarians (5g daily for 42 days) failed to find a reduction in postprandial blood glucose.[351]

1-3 Minutes Rest: Ideal for “tension and fatigue exercises,” which include most secondary compound exercises. This range is sort of the midpoint between being ideal for strength and being ideal for generating fatigue. So while it’s not entirely what’s best for either, it is what’s perfect for achieving an equal combination of the two… which is exactly what we want from these exercises.

Proceedings of the National Academy of Sciences of the United States of America. 106 (36): 15268–73. Bibcode:2009PNAS..10615268S. doi:10.1073/pnas.0907352106. PMC 2741240. PMID 19706398.
A maintenance phase of 2g daily appears to technically preserve creatine content in skeletal muscle of responders either inherently or after a loading phase, but in sedentary people or those with light activity, creatine content still progressively declines (although it still higher than baseline levels after six weeks) and glycogen increases seem to normalize. This maintenance dose may be wholly insufficient for athletes, a 5g maintenance protocol may be more prudent.
Discomfort can arise from other factors. Individuals who perform large numbers of repetitions, sets, and exercises for each muscle group may experience a burning sensation in their muscles. These individuals may also experience a swelling sensation in their muscles from increased blood flow (the "pump"). True muscle fatigue is experienced as a marked and uncontrollable loss of strength in a muscle, arising from the nervous system (motor unit) rather than from the muscle fibers themselves. Extreme neural fatigue can be experienced as temporary muscle failure. Some weight training programs, such as Metabolic Resistance Training, actively seek temporary muscle failure; evidence to support this type of training is mixed at best.[24] Irrespective of their program, however, most athletes engaged in high-intensity weight training will experience muscle failure during their regimens.
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.
Creatine supplementation appears to be somewhat similar to TMG supplementation in the sense that they both promote localized synthesis of phosphatidylcholine, effluxing triglycerides from the liver into serum and thus potently protecting from diet-induced fatty liver. The concentration at which this occurs is within the range supplemented by humans.
How to Take It: If you decide you want to take BCAAs as one of your weight lifting supplements, you can easily get them and take them much like you would protein powders. One scoop provides 2.5g of leucine, 1.25g of isoleucine and 1.25g of valine. Take it before a workout, during or after. As with all supplementation, the aim is to reach your overall daily needs and goals.
How to do it: Stand with feet just outside the shoulders and hands behind your head. Squat, keeping your knees behind your toes and squeezing your glutes. After holding this position for two seconds, jump vertically. Pull the toes to your shins in midair to prepare for landing. Land in the starting squat position, hold three seconds and repeat for 10 reps. Be sure to land softly, with the hips back and down.

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.
Over time, we naturally lose muscle mass in a process called sarcopenia. On average, men lose about 30% of their muscle mass during their lives. Usually, this begins in your 30s and progresses slowly as you age. But, don’t despair. You can rebuild and maintain muscle mass even as you age. Often, diet and exercise are enough. But, sometimes, if the above hormones play a role, your doctor may recommend medications and additional treatments (4).
A 2011 survey of 33 supplements commercially available in Italy found that over 50% of them exceeded the European Food Safety Authority recommendations in at least one contaminant. The most prevalent of these contaminants was creatinine, a breakdown product of creatine also produced by the body.[47] Creatinine was present in higher concentrations than the European Food Safety Authority recommendations in 44% of the samples. About 15% of the samples had detectable levels of dihydro-1,3,5-triazine or a high dicyandiamide concentration. Heavy metals contamination was not found to be a concern, with only minor levels of mercury being detectable. Two studies reviewed in 2007 found no impurities.[41]
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.
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.
Yes, genetically some of us put on muscle faster than others, but even then it’s fractions of a degree, not DRASTIC sweeping differences.

A: First, you have to realize that when one is gaining weight it’s nearly impossible (steroid discussion aside) to gain solely muscle without the acquisition of some body fat as well. That being said though, you can improve thedistribution of lean body mass to fat mass by ensuring that your calorie consumption isn’t too aggressive (i.e. 1000+ over your BMR). Also, it should go without saying, but you need to be training hard while focusing on progressive overload to ensure that the calories you’re ingesting are actually going towards muscle growth. You shouldn’t be neglecting cardiovascular work either; both HIIT and LISS each play a role in enhancing mitochondrial density, balancing neurotransmitters, improving oxidative capacity, and influencing brain plasticity.

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]

Perhaps 1 to 2% of intramuscular creatine is degraded into creatinine each day, which is excreted in urine. Therefore, approximately 1 to 3 g of creatine needs replenishing daily to maintain basal levels. Some of this replacement is fulfilled by the liver and kidneys, which can use the amino acids arginine and glycine to synthesize creatine. A tiny minority of people has gene mutations that result in impaired creatine synthesis or transport. These unfortunate people experience severe neurodevelopmental problems beginning early in life and benefit from consuming more creatine in their diets.


“I would really focus on learning how macros work, how your body works and how it reacts to certain foods, and what your body requires each day to maintain your weight,” he advises. “Then you can start playing around with increasing calories [to bulk up], and decreasing calories when you're dieting.” Our beginner's guide to macros will definitely help.
Citrulline Malate is an amino acid also known as L-Citrulline and is taken for many different medical conditions. There is some research that shows that the amino acid may help improve performance while exercising by reducing fatigue. What does that mean for you? In your muscle building efforts, you can use this supplement to help you make it through longer, harder workouts. This will spur more muscle building in response to the trauma your muscles experience in a tough workout. Not only that, but Citrulline Malate can also help reduce soreness after a workout. Who doesn’t want to avoid feeling sore? Reduced soreness means you can get back to the gym the next day with renewed enthusiasm.
Although creatine can be bought commercially as a standalone product it is often found in combination with other nutrients. A prime example is the combination of creatine with carbohydrate or protein and carbohydrate for augmenting creatine muscle retention [5] mediated through an insulin response from the pancreas [69]. Steenge et al [70] found that body creatine retention of 5 g CM was increased by 25% with the addition of 50 g of protein and 47 g of carbohydrate or 96 g carbohydrate when compared to a placebo treatment of 5 g carbohydrate. The addition of 10g of creatine to 75 g of dextrose, 2 g of taurine, vitamins and minerals, induced a change in cellular osmolarity which in addition to the expected increase in body mass, seems to produce an up regulation of large scale gene expression (mRNA content of genes and protein content of kinases involved in osmosensing and signal transduction, cytoskeleton remodelling, protein and glycogen synthesis regulation, satellite cell proliferation and differentiation, DNA replication and repair, RNA transcription control, and cell survival) [25]. Similar findings have also been reported for creatine monohydrate supplementation alone when combined with resistance training [71].

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.


Despite a possible decreasing creatine content in the muscles when maintenance is deemed suboptimal, the overall retention of weight and lean mass is merely additive over time. This is thought to be due to increases in skeletal muscle production (increase in body weight) compensating for the progressive declines in water and glycogen content (decreases in body weight).
Some people recommend first “loading” creatine (typically consuming 5 g 4 times a day for 5 to 7 days). This isn’t necessary though, for muscle stores will be saturated regardless after a few weeks. Remember that you can also use creatine as an alternative to things like caffeine to acutely to ward off some of the negative consequences of sleep loss.
Taking creatine supplements may increase the amount of creatine in the muscles. Muscles may be able to generate more energy or generate energy at a faster rate. Some people think that taking creatine supplements along with training will improve performance by providing quick bursts of intense energy for activities such as sprinting and weightlifting.
Three additional studies suggest that creatine supplementation may not be beneficial for running velocity, sprint swimming performance, or a maximal cycling effort [7]. Short bouts of repeated anaerobic activity have shown some potential benefits with creatine supplementation use in a laboratory setting. However, creatine supplementation has not been shown to enhance single-event performance such as stationary cycling [16-19]. Taken together, these studies do not support creatine supplementation to enhance aerobic activities such as distance running.
A: The literature supports roughly 0.8-1 gram per pound of bodyweight in young adults. Can you eat more? As long as you have healthy, functioning kidneys, yes. Will you receive any further physiological benefit from it? Most likely, no. Not only that, since our calories are set, if we choose to overconsume protein then we must reduce either carbohydrates and/or fat in order to keep caloric expenditure within our set range. Once protein needs are met (~0.8-1g/lb of bodyweight) you will likely see greater benefits from higher carbohydrate consumptions given the influence they have on anabolism and the anaerobic energy pathway. However, as I mentioned above, these recommendations will differ for older trainees given the blunted anabolic response from the ingestion of amino acids. 
A flat, atrophied butt doesn't just look bad in jeans or swimsuits—it’s also likely contributing to your tight hips and back problems. If not, it soon will be. That’s because a flat butt is a symptom of tight hips and hamstrings, the result of poor glutes activation. In an ideal world, they all work together to stabilize the pelvis and produce many years of fluid movement.
Anti-cancer effects have been observed with the creatine analogue cyclocreatine[456][104][457] and have been replicated with creatine itself. These effects tend to be a reduction in which the rate of implanted tumors progresses.[458][459] It is suspected that these observed effects (inhibition of growth or attenuation of the rate of growth) are not due to the bioenergetic effect of creatine, secondary to creatine kinase. These anti-cancer effects do not have a known reliability, as the expression of creatine kinase varies widely based on the type of tumor.[460] However, some studies suggest an inverse relationship between tumor progression in mice and concentrations of creatine in cells, with creatine depletion coinciding with tumor development.[460]

Antioxidants in the diet protect against natural and synthetic chemical fragments called free radicals that are a part of daily living. Lifestyle challenges may increase your requirements for antioxidants. Vitamin C and E are the main antioxidants in the normal diet although many other plant nutrients contribute to this effect. Pollution, stress, smoking, strenuous exercise, and illness may increase your requirements for antioxidant protection.

As I mentioned earlier, the exercises that come first in your workout (aka primary compound exercises) should usually be done in the 5-8 rep range. Exercises in the middle (aka your secondary compound exercises) should usually be done in the 8-10 rep range. Exercises done at the end of your workout (which is typically where isolation exercises belong) should usually be done in the 10-15 rep range.


Most experts recommend starting with your larger muscle groups and then proceeding to the smaller muscle groups. The most demanding exercises are those performed by your large muscle groups and you will need your smaller muscles to get the most out of these exercises. But, don't feel limited by that. You can do your exercises in any order you like and changing the order is a great way to challenge yourself in different ways.
However, a much more accurate determination of how much fluid is necessary can be made by performing appropriate weight measurements before and after a typical exercise session, to determine how much fluid is lost during the workout. The greatest source of fluid loss during exercise is through perspiration, but as long as your fluid intake is roughly equivalent to your rate of perspiration, hydration levels will be maintained.[14]

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 the 1970s, bodybuilding had major publicity thanks to the appearance of Arnold Schwarzenegger, Franco Columbu, Lou Ferrigno, and others in the 1977 docudrama Pumping Iron. By this time, the IFBB dominated the competitive bodybuilding landscape and the Amateur Athletic Union (AAU) took a back seat. The National Physique Committee (NPC) was formed in 1981 by Jim Manion,[7] who had just stepped down as chairman of the AAU Physique Committee. The NPC has gone on to become the most successful bodybuilding organization in America and is the amateur division of the IFBB. The late 1980s and early 1990s saw the decline of AAU-sponsored bodybuilding contests. In 1999, the AAU voted to discontinue its bodybuilding events.
