Research shows that starting as early as age 30, the body begins to slowly lose muscle mass, with women losing up to 15 percent of their total-body muscle per decade by age 50. Apart from declines in strength, that declining muscle mass comes with a declining metabolism, Emilia Ravski, D.O., a sports medicine specialist with Hoag Orthopedic Institute in California, tells SELF. This decline in metabolic rate is actually one driving factor of the weight that women generally tend to put on after we naturally hit our peak muscle levels in our 20s, research from Tufts University suggests.
Sculthorpe et al (2010) has shown that a 5 day (25g/d) loading protocol of creatine supplementation followed by a further 3 days of 5 g/d negatively influence both active ankle dorsiflexion and shoulder abduction and extension range of movement (ROM) in young men. There are two possible theories to explain these effects: 1) Creatine supplementation increases intracellular water content resulting in increased muscle stiffness and resistance to stretch; 2) Neural outflow from the muscle spindles is affected due to an increased volume of the muscle cell. The authors highlight that the active ROM measures were taken immediately after the loading phase and the reduced active ROM may not be seen after several weeks of maintenance phase [45]. Hile et al [46] observed an increase in compartment pressure in the anterior compartment of the lower leg, which may also have been responsible for a reduced active ROM.
It has also been noted that supplementing creatine (which reduces internal synthesis of creatine and methylation requirements) preserved folate and tetrahydrofolate status (42% and 23%),[312] which acted to preserve methyl groups for other processes. Despite this effect, global DNA methylation decreases by 22% (assessed by the 5-methylcytosine/cytosine ratio) following creatine supplementation, which is usually seen as an anti-cancer effect in developed mammals.[461] This study was unable to demonstrate why this reduction occured[461] and opposing effects have been noted in females with Rett syndrome supplementing 200mg/kg creatine for 1 year, during which global methylation increased, secondary to preserving other methyl donors.[462]
Creatine is most commonly used for improving exercise performance and increasing muscle mass in athletes and older adults. There is some science supporting the use of creatine in improving the athletic performance of young, healthy people during brief high-intensity activity such as sprinting. Because of this, creatine is often used as a dietary supplement to improve muscle strength and athletic performance. In the U.S., a majority of sports nutrition supplements, which total $2.7 billion in annual sales, contain creatine.
Several review studies assessing the safety of creatine supplementation tend to make note of increases in formaldehyde and possible carcinogenic results.[451][452] Specifically, creatine is metabolized into an intermediate called methylamine, which can be converted to formaldehyde by the SSAO enzyme.[453] An increase in urinary formaldehyde has been noted in youth given 21g of creatine for one week, during which both methylamine (820% increase) and formaldehyde (350%) were increased, relative to control.[454] However, a more prolonged study using 300mg/kg (loading dose of around 20g) in adults for ten weeks failed to replicate these effects.[455]
There are many camps within the weight training fitness community. We have bodybuilders, Crossfit athletes, powerlifters, Olympic lifters, and strongman athletes just to name the most popular ones off the top of my head. One thing they all have in common is that they all use resistance to achieve a particular goal. They all also “share” particular exercises. Most resistance-training athletes do barbell squats, overhead presses and deadlifts. I can write pages of differences between each of the disciplines I listed above and I can also write quite a bit about their similarities but one form of resistance training is MORE different than the others. Bodybuilding is the only sport that judges the appearance of the athlete rather than their performance. This may be why bodybuilders tend to get poked at the most.

The first open label trial on ALS failed to significantly alter lung function as assessed by FEV (when comparing the rate of decline pretreatment relative to treatment).[545] Creatine has elsewhere failed to benefit lung function at 5g daily for months relative to control[546] and failed to significantly attenuate the rate of lung function deterioration over 16 months at 10g daily[505] and 5g daily over nine months.[507]

Genetic deficiencies in the creatine biosynthetic pathway lead to various severe neurological defects.[26] Clinically, there are three distinct disorders of creatine metabolism. Deficiencies in the two synthesis enzymes can cause L-arginine:glycine amidinotransferase deficiency caused by variants in GATM and guanidinoacetate methyltransferase deficiency, caused by variants in GAMT. Both biosynthetic defects are inherited in an autosomal recessive manner. A third defect, creatine transporter defect, is caused by mutations in SLC6A8 and inherited in a X-linked manner. This condition is related to the transport of creatine into the brain.[27]

Our bodies store creatine in our muscles so that we have quick access to it for fast, high-intensity movements, like sprinting or powerlifting, explains Autumn Bates, a certified clinical nutritionist and sports nutritionist in private practice in Manhattan Beach, California. “It's a nonessential amino acid, meaning your body creates it and you don't need to primarily get it from food.”


It can be hard not to compare yourself to Schwarzenegger, with his action-star movie career, his stint as a president-appointed fitness ambassador and his election as governor of California. Chang said that Heath’s personality, including his charisma and outspokenness, is similar to that of Schwarzenegger, who is still omnipresent and beloved in the sport.
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 ethyl ester increases muscle levels of creatine to a lesser degree than creatine monohydrate.[72] It may also result in higher serum creatinine levels[73] due to creatine ethyl ester being converted into creatinine via non-enzymatic means in an environment similar to the digestive tract.[74][75] At equal doses to creatine monohydrate, ethyl ester has failed to increase water weight after 28 days of administration (indicative of muscle deposition rates of creatine, which are seemingly absent with ethyl ester).[76] 

However, don’t despair over the poor reviews. There are other ways to achieve a testosterone booster for muscle gain. One of them is simply Vitamin D. A deficiency in this vitamin can lower your levels of testosterone. Furthermore, you can get a very natural boost simply by weightlifting and engaging in HIIT (High Intensity Interval Training) exercise. In addition, you should avoid some foods like soy and alcohol which can lower testosterone levels (11). Through these natural solutions and lifestyle changes, you can influence your hormone profile, creating a balance that’s more favorable for muscle growth.

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.
If you stop getting the results you want after several weeks of working out, it's time to mix things up. You need to challenge or "confuse" your muscles often to keep them growing. You can do this by putting a twist on your basic moves. Do a biceps curl with a reverse grip, for example. Or find a bench for the step-up move shown here. Change up your workout at least every 4 to 6 weeks for the best results.
When endothelial cells have a higher creatine concentration, they appear to be mildly less permeable when incubated with 0.5-5mM creatine, while the higher concentration (5mM) is able to fully ablate TNF-α-induced neutrophil adhesion and both E-selectin and ICAM-1 expression.[316] This effect was prevented with ZM241385, an A2A (adenosine) receptor antagonist,[316] and since adenosine released by this receptor is known to be protective of endothelial cells,[317][318] it is thought that creatine works vicariously through this receptor and adenosine release, thought to be due to releasing ATP (occurs in response to stress[319][320]) which protects the cell via the A2A signaling system.[316]
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.
Weight training also requires the use of 'good form', performing the movements with the appropriate muscle group, and not transferring the weight to different body parts in order to move greater weight (called 'cheating'). Failure to use good form during a training set can result in injury or a failure to meet training goals; since the desired muscle group is not challenged sufficiently, the threshold of overload is never reached and the muscle does not gain in strength. At a particularly advanced level; however, "cheating" can be used to break through strength plateaus and encourage neurological and muscular adaptation.
Bodybuilders do cardio training such as running and using a StairMaster StepMill to burn fat and make their muscles more visible. “Do cardio throughout the year at least three days a week for at least 30-40 minutes, whether it be first thing in the morning on an empty stomach or after a post-workout protein shake,” says Heath. “Cardio won’t kill your gains as much as you think, you’ll see how much muscle you really have.” Break a sweat to stay lean ’round the clock.
However, caffeine does not negate the benefits of creatine loading when not coingested, but just taken before exercise in the same dosage.[593] This result indicates that loading creatine without caffeine on a daily basis, but saving caffeine for select workouts, may be an effective strategy, as creatine does not adversely affect caffeine’s ergogenic effects[593][594] and may enhance creatine’s effectiveness in anaerobic exertion if the two compounds are alternated.[595]

The right amount of workout: It is highly possible that the protein powder you are taking doesn’t work on your body. Supplements should only be taken if you have a rigorous workout schedule or else, it will turn out to be of no value. Most people just purchase a box of supplements without really doing the math, which is very important. Unless you find out the dosage that suits you, the amount of time you should dedicate for the workout and so on, you must not expect daydream the results. 
In weight training, as with most forms of exercise, there is a tendency for the breathing pattern to deepen. This helps to meet increased oxygen requirements. Holding the breath or breathing shallowly is avoided because it may lead to a lack of oxygen, passing out, or an excessive build up of blood pressure. Generally, the recommended breathing technique is to inhale when lowering the weight (the eccentric portion) and exhale when lifting the weight (the concentric portion). However, the reverse, inhaling when lifting and exhaling when lowering, may also be recommended. Some researchers state that there is little difference between the two techniques in terms of their influence on heart rate and blood pressure.[8] It may also be recommended that a weight lifter simply breathes in a manner which feels appropriate.
Side-Effects: While the signs of a great body may make one think that there cannot be anything wrong with bodybuilding supplements, the facts speak otherwise. Bodybuilding supplements do have side-effects and you must listen to your trainer before giving in to the thoughts of buying one. Creatine can cause heart problems, kidney problems, dehydration, diarrhoea and muscle cramping. You must also discuss your medical history with the trainer.

Need the motivation to push past your comfort zone and squeeze out one more push-up or bicep curl? Sure, it helps to remember that you’ll get stronger, rock more toned muscles and rev your metabolism, thanks to all that added muscle mass. But if that wasn’t enough, now comes news that all that pump-itude (yes, that’s an SNL reference) has psychological benefits, too.
Spero Karas, MD, assistant professor of orthopaedics in the division of sports medicine at Emory University, says that testosterone, the male hormone responsible for muscle growth, maxes out between the ages of 16 and 18. It reaches a plateau during the 20s and then begins to decline. As a result, muscle building after the adolescent years can be challenging, he says. 

Some of the most common minor side effects include stomach discomfort, nausea, and increased bowel movements. Other potential side effects may include headaches, bloating, and increased thirst. There is always the chance that a supplement could cause an allergic reaction. This can result in rashes, swelling, or difficulty breathing, depending on the severity of the reaction. This is another reason why starting out with lower doses of new products is advisable.
At the end of the day, you have to focus on how you feel. “Listen to your body,” says Davis. “It tells you when it needs a day off.” As a rule of thumb, take a rest day if your perceived pain is above a seven on a scale of 10, Davis advises. Or, focus on a different body part (say, if your legs are sore, focus on upper-body moves). Can't stop, won't stop—at least, till your next rest day.
Ghost Size takes the cake for muscle growth. The key to this formula is epicatechin, an antioxidant found in chocolate and certain plants that is linked to a wide array of benefits. These include increased nitric oxide produciton, better oxygenation to the brain, and muscle growth: epicatechin appears to inhibit myostatin, which suppresses muscle growth, and the dosage found in Ghost Size is in line with studies that examined this effect.

Most experts recommend starting with your larger muscle groups and then proceeding to the smaller ones. 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.

Studies conducted in vegetarians tend to show cognitive enhancement in youth, possibly due to a creatine deficiency, as compared to omnivores.[272][60][61] Vegetarian diets have lower levels of circulating creatine prior to supplementation, but attain similar circulating levels as omnivores when both groups supplement.[272][273] Building on the latter, supplementation of creatine monohydrate in a loading protocol (20g daily in orange juice) in omnivores does not alter levels of creatine in white matter tissue in the brain (test subjects: competitive athletes).[274] In most of the parameters that vegetarians experience benefits, omnivores fail to experience statistically significant benefits[275], except possibly when sleep deprived, where the cognitive improvements rival that seen in vegetarians.[276] Elderly people who are omnivorous may also experience increases in cognition to a similar level, in regard to long-term memory as well as forward number and spatial recall, although the study in question failed to find any significant benefit on backward recall or random number generation,[38] the latter of which is a test for executive working memory.[277]
In complex training, weight training is typically combined with plyometric exercises in an alternating sequence. Ideally, the weight lifting exercise and the plyometric exercise should move through similar ranges of movement i.e. a back squat at 85-95% 1RM followed by a vertical jump. An advantage of this form of training is that it allows the intense activation of the nervous system and increased muscle fibre recruitment from the weight lifting exercise to be utilized in the subsequent plyometric exercise; thereby improving the power with which it can be performed. Over a period of training, this may enhance the athlete's ability to apply power.[39] The plyometric exercise may be replaced with a sports specific action. The intention being to utilize the neural and muscular activation from the heavy lift in the sports specific action, in order to be able to perform it more powerfully. Over a period of training this may enhance the athlete's ability to perform that sports specific action more powerfully, without a precursory heavy lift being required.
There appears to be some potential for creatine supplementation. However, many questions remain. Are there any long-term harmful effects from supplementation? Is there a point where enhanced performance levels off from long-term supplement usage? What effect does "stacking" or taking two ergogenic aids simultaneously have on the body? What happens if you immediately stop taking the creatine supplement? Is the enhanced performance great enough to warrant the expense of the supplement? Until further research answers these questions, creatine is not recommended for the average athlete.
The genealogy of lifting can be traced back to the beginning of recorded history[1] where humanity's fascination with physical abilities can be found among numerous ancient writings. In many prehistoric tribes, they would have a big rock they would try to lift, and the first one to lift it would inscribe their name into the stone. Such rocks have been found in Greek and Scottish castles.[2] Progressive resistance training dates back at least to Ancient Greece, when legend has it that wrestler Milo of Croton trained by carrying a newborn calf on his back every day until it was fully grown. Another Greek, the physician Galen, described strength training exercises using the halteres (an early form of dumbbell) in the 2nd century.
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.
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.

You've figured out the exercises you should be doing, but what about the number of sets and repetitions? Your decision should be based on your goals. The American College of Sports Medicine recommends 4 to 6 reps for strength and hypertrophy, 8 to 12 reps for muscular strength and 10 to 15 reps for muscular endurance. They also recommend at least one set of each exercise to fatigue although you'll find that most people perform about 2 to 3 sets of each exercise. In general:

GLUTs are vesicle transporters that are the rate-limiting steps for bringing glucose into a cell, and GLUT4 is the most active variant.[327] Agents that reduce blood glucose (insulin or AMPK) are known to act via mobilizing GLUT4, and increased GLUT4 expression and activity is indicative of a greater ability to bring glucose into a cell, while reducing it impairs glucose uptake.[328] Rat studies have confirmed that creatine feeding increases muscular GLUT4 expression associated with increased insulin-stimulated glucose uptake.[329]
Some bodybuilders use drugs such as anabolic steroids and precursor substances such as prohormones to increase muscle hypertrophy. Anabolic steroids cause hypertrophy of both types (I and II) of muscle fibers, likely caused by an increased synthesis of muscle proteins. They also provoke undesired side effects including hepatotoxicity, gynecomastia, acne, the early onset of male pattern baldness and a decline in the body's own testosterone production, which can cause testicular atrophy.[42][43][44] Other performance-enhancing substances used by competitive bodybuilders include human growth hormone (HGH), which can cause acromegaly.

In muscle cells, the creatine transporter is predominantly localized to the sarcolemmal membrane. Western blot analysis of creatine transporter expression revealed the presence of two distinc protein bands, migrating at 55kDa and 70kDa on reducing SDS-PAGE gels.[147][148] The 73kDa band has been reported to be the predominant band in humans, with no differences based on gender.[148] A more recent report demonstrated that the 55kDa creatine transporter variant is glycosylated, forming the 73 kDa protein. Therefore, the 55 and 75kDa protein bands are actually immature and mature/processed forms of the creatine transporter protein, respectively.[149]
It is equally important, if not more so, to ensure that you supply your body with more protein than it is breaking down each day. Your body uses protein for many things daily, and when you are working out, your body may start to break down proteins to provide extra energy. But your body also requires proteins to create new muscle cells and repair damaged ones. Many bodybuilding supplements contain large amounts of protein to ensure that your body has plenty for all required processes. Jump to Our 10 Best Bodybuilding Supplement List
