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.
Generally, you should consume about 20 grams of protein with some carbs shortly after a workout. During the post-workout anabolic window, you’ll also want to limit fats, which can slow the absorption of protein. While there is some recent research that suggests the window may actually extend up to several hours following exercise, there’s no harm in getting nutrients in early as long as you’re sticking to your overall caloric and macronutrient goals.

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].

Elsewhere, it has been noted that in chronic progressive external ophthalmoplegia (CPEO, a progressive weakening of the muscles around the eye and a mitochondrial disorder), there was a failure of creatine supplementation to benefit symptoms when subjects were provided 20g daily for four weeks.[483] Creatine supplementation failed again at 150mg/kg for six weeks in people with either CPEO or another disorder associated with single gene deletions affecting the eyes (Kearns–Sayre syndrome, KSS) in improving muscular function.[484]
Great! Start with strength training 🙂 When you’re overweight, my guess is that you want to be preserving the muscle you have while losing the majority of your weight through fat. With strength training, your overall weight loss may seem slower, but you will lose inches faster. Strength training increases your metabolism; as long as you’re still eating in a deficit, you’ll lose weight.
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.
However, the basis of “take creatine after your workout” comes from a 2013 study published in the JISSN, which can be found here (open access too!). In this study, recreational male bodybuilders (19 men overall) were given five grams of creatine either before or after their workouts. They trained five days per week but were also directed to consume 5g on their rest days at any time they wanted. The workouts were fairly similar to most gym workouts, and the methodology (what they did and how they did it) suggests that the findings would apply to most weightlifters.

A: At the end of the day, the most important variable regarding weight gain or loss is calorie consumption. However, meal frequency and timing around activity can both influence workout intensity and duration thus potentially allowing for further improvements in body composition. Remember, muscle growth isn’t a pulsatile process, it doesn’t just acutely spike and then return to baseline so if there aren’t circulating amino acids within the blood stream then they’ll have to be broken down from muscle as this is the highest form of concentrated amino acids within the body. That being said, it would probably be a good idea to consume anywhere from 3-6 meals spread throughout the day depending upon your schedule and preference. Ideally, we want to stimulate anabolism through food every 3-5 hours.

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.
Your glutes serve as the main mover and power output to most of your major and accessory lifts—squat, deadlift, kettbell swings, box jumps—so the more you develop and stimulate your gluteal muscles, the more you’re able to maximize control, strength, and stability. (It doesn’t hurt that women love watching you do leg and glute work in the gym, either.)
Polyethylene glycol is a non-toxic, water-soluble polymer that is capable of enhancing the absorption of creatine and various other substances [66]. Polyethylene glycol can be bound with CM to form polyethylene glycosylated creatine. One study [67] found that 5 g/d for 28 days of polyethylene glycosylated creatine was capable of increasing 1RM bench press in 22 untrained young men but not for lower body strength or muscular power. Body weight also did not significantly change in the creatine group which may be of particular interest to athletes in weight categories that require upper body strength. Herda et al [68] analyzed the effects of 5 g of CM and two smaller doses of polyethylene glycosylated creatine (containing 1.25 g and 2.5 g of creatine) administered over 30 days on muscular strength, endurance, and power output in fifty-eight healthy men. CM produced a significantly greater improvement in mean power and body weight meanwhile both CM and polyethylene glycosylated form showed a significantly (p < 0.05) greater improvement for strength when compared with control group. These strength increases were similar even though the dose of creatine in the polyethylene glycosylated creatine groups was up to 75% less than that of CM. These results seem to indicate that the addition of polyethylene glycol could increase the absorption efficiency of creatine but further research is needed before a definitive recommendation can be reached.
How to do it: Lie flat on your back with your feet firmly planted on the floor, knees bent, as if you’re doing a standard bridge. Keeping one foot fixed to the ground, lift the other up, keeping the bend in your knee. Drive your hips up toward the ceiling, driving through your planted leg and using the raised leg to keep your pelvis even and balanced. Don’t let your non-working leg/side drop, Reames advises, and keep emphasizing the heel plant. Lower toward the ground, then repeat.
Extracellular creatine (creatine outside of a cell) appears to influence creatine uptake into a cell. It seems that prolonged and excessive levels of creatine actually suppress uptake (a form of negative regulation to prevent excessive influx).[180] In vitro studies in rat muscle cells have shown that including 1mM creatine into cell culture medium substantially reduces creatine uptake into cells. The inhibitory effect was partially negated by protein synthesis inhibitors, suggesting that high levels of creatine induce the expression of a protein that suppresses creatine transporter activity.[180] Similar findings were reported in a later study in cultured mouse myoblasts, which noted a 2.4-fold increase in intracellular creatine levels in the presence of the protein synthesis inhibitor cyclohexamide.[174]

When many people think of someone with a high level of testosterone, they may picture a man loaded with strength, sexual prowess, and machismo. But while high-T has been correlated with all those things, it’s also been correlated with aggression, sexual misconduct, and violence. One of testosterone’s most common uses—as a performance-enhancing steroid—illustrates both sides of the hormone. Injecting steroids can be a quick way for athletes to dramatically improve performance, but the side effects can also be extreme, and can include excessive body hair growth, sexual dysfunction, and the hard-to-corral anger known as “roid rage.”
Objective: Are you getting stronger? Increasing either weight or reps? If you're measuring individual markers on a daily basis like vertical jump, grip strength, or resting heart rate then what sort of trends are you noticing in these variables? If they're staying the same while your strength is increasing, then you're recovering well. If they're decreasing and you find yourself weaker over time then you're not recovering well.
Testosterone is necessary for normal sperm development. It activates genes in Sertoli cells, which promote differentiation of spermatogonia. It regulates acute HPA (hypothalamic–pituitary–adrenal axis) response under dominance challenge.[22] Androgen including testosterone enhances muscle growth. Testosterone also regulates the population of thromboxane A2 receptors on megakaryocytes and platelets and hence platelet aggregation in humans.[23][24]

Some protein powders are loaded with junk. We recommend this grass-fed protein isolate because it is a non-GMO product and contains no artificial sweeteners. It is a US-based product, and the whey protein is cultivated from American cows. With 28 grams of protein in one scoop, one spoonful of this powder may provide the equivalent protein profile of a whole meal. What’s even better is that one scoop is only 120 calories. This powder gives you quite a bit of protein for minimal calories, keeping you lean.
Creatine supplementation appears to attenuate decreases in GLUT4 expression seen with immobility and may increase GLUT4 expression during exercise. While it seems capable of increasing GLUT4 during resting conditions, it has failed to reach significance, suggesting that creatine supplementation works best with some stimuli associated with exercise.

How: Place a resistance band around both legs, just above or below your knees. Stand with feet just wider than hip-width apart, toes turned out slightly, hands clasped in front of chest. Keeping weight in your heels, send your butt and hips back as if sitting in a chair and lower down as far as possible, pressing your legs outward against the band. Return to starting position and repeat.


Perform the workout three days a week for four weeks, resting at least one day between each session. On the weight exercises, choose a load that allows you to complete a few more reps than the prescribed number (you may need to adjust this load between sets as you discover your strength levels). For instance, if an exercise calls for 12 reps, choose a load that you estimate you can perform 15 reps with before having to stop (but complete only 12).
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]
What kind of exercises? Work all major muscle groups, starting with the larger muscles. Always include exercises for opposing muscles: for example, work the biceps and triceps of your arms, and the quadriceps and hamstrings of your thighs. Avoid above-the-shoulder exercises if you have arthritis in your upper body, and talk to your doctor before using leg press machines if you have arthritis in your knees or hips.

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]
Researchers described the study as one of the first to examine how strength training can reduce the risk of cardiovascular disease, separate from the effects of aerobic activity like running or long walks. The point: for those who are not meeting recommended guidelines for aerobic activity—perhaps because they lack the time—bursts of weight training can be enough.

The failure of creatine to improve physical performance in these conditions is thought to be related to the myopathies in general, which are known to result in less phosphocreatine in skeletal muscle,[568] associated with reduced expression of the creatine transporter.[569] As creatine has once been noted to not accumulate in the skeletal muscle of people with DM1 given supplementation,[566] it is thought that the subjects did not respond to therapy.
Lie on your left side. Rest your head on your left arm. Bend your hips to approximately 45 degrees and bend your knees at 90 degrees. Make sure one hip is lying above the other so your knees are stacked perfectly and your feet are aligned with your back. Now, float the upper leg upwards while keeping your feet in contact with one another, then return. Repeat for required reps, then switch sides.
Creatine is classified as a "dietary supplement" under the 1994 Dietary Supplement Health and Education Act and is available without a prescription. Creatine is not subjected to FDA testing, and the purity and hygienic condition of commercial creatine products may be questionable [21]. A 1998 FDA report lists 32 adverse creatine-associated events that had been reported to FDA. These include seizure, vomiting, diarrhea, anxiety, myopathy, cardiac arrhythmia, deep vein thromboses and death. However, there is no certainty that a reported adverse event can be attributed to a particular product [22]. A recent survey of 28 male baseball players and 24 male football players, ages 18 to 23, found that 16 (31%) experienced diarrhea, 13 (25%) experienced muscle cramps, 7 (13%) reported unwanted weight gain, 7 (13%) reported dehydration, and 12 reported various other adverse effects [23].
Try this little exercise some time: follow the supplement plan provided above for at least three months. Then quit all supplement use for a further three months and watch what happens. Sure, most supplement marketing involves hype and some companies make laughably outrageous claims, but there is no secret as to why the supplement industry is booming. Supplements work.
Creatine is produced endogenously at an amount of about 1 g/d. Synthesis predominately occurs in the liver, kidneys, and to a lesser extent in the pancreas. The remainder of the creatine available to the body is obtained through the diet at about 1 g/d for an omnivorous diet. 95% of the bodies creatine stores are found in the skeletal muscle and the remaining 5% is distributed in the brain, liver, kidney, and testes [1]. As creatine is predominately present in the diet from meats, vegetarians have lower resting creatine concentrations [2].
In addition to being potentially harmful, some have argued that there is little evidence to indicate any benefit to using bodybuilding protein or amino acid supplements. "In view of the lack of compelling evidence to the contrary, no additional dietary protein is suggested for healthy adults undertaking resistance or endurance exercise".[18] In dispute of this, one more recent meta-analysis concluded that for athletes participating in resistance exercise training and consuming protein supplements for an average of 13 weeks, total protein intake up to 1.6 g per kg body weight per day would result in an increase in strength and fat-free mass, i.e. muscle, but that higher intakes would not further contribute. The muscle mass increase was statistically significant but modest - averaging 0.3 for all trials and 1.0 to 2.0 kg, for protein intake ≥ 1.6 g/kg/day.[3]
In males, testosterone is synthesized primarily in Leydig cells. The number of Leydig cells in turn is regulated by luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In addition, the amount of testosterone produced by existing Leydig cells is under the control of LH, which regulates the expression of 17β-hydroxysteroid dehydrogenase.[132]
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.
Testosterone is most commonly associated with sex drive in men. It also affects mental health, bone and muscle mass, fat storage, and red blood cell production. Abnormally low or high levels can affect a man’s mental and physical health. Your doctor can check your testosterone levels with a simple blood test. Testosterone therapy is available to treat men with low levels of testosterone. If you have low T, ask your doctor if this type of therapy might benefit you.
I bought this for my husband since he recently started lifting again. I knew that he wanted to gain as much muscle mass as possible and this looked like a pretty good product. It comes in a nice black bottle with good labeling. The bottle contains 90 capsules, which is about a month and a half worth of supplements. He has been taking 2 capsules before bed each night and for the past few weeks and has had no negative side effects. It's also really easy to remember since you take the both at the same time instead of spread throughout the day. He says that he has noticed a difference most of all in his muscle tone and just an overall feeling of being refreshed.
A good way to determine how much fat in grams you should be taking in is to multiply your calorie intake by 0.001 for maximum trans-fats; by 0.008 for maximum saturated fats; and by 0.03 for the "good fats". For example, for a 2,500-calorie diet, you would limit trans-fats to 3g or less, saturated fats to 20g or less, and up to 75g of mono- and polyunsaturated fats.
In addition to adequate protein, you need more calories (your protein intake contributes to your total caloric intake, so these two go hand in hand). Use the following formula to calculate the number you need to take in daily to gain one pound a week, and break down your diet using the macro guidelines listed above. (Give yourself two weeks for results to show up on the scale. If you haven't gained by then, increase your calories by 500 a day.)
In the stomach, creatine can degrade by about 13% due to the digestive hormone pepsin, as assessed by simulated digestion.[127] Although creatinine is a known byproduct of creatine degradation, simulated gastric digestion did not increase creatinine levels, indicating that other breakdown products were formed. However, creatinine was noted to increase in the presence of pancreatin, a mixture of pancreatic enzymes.[127]

In fact, in one new study comparing the effects of aerobic exercise versus resistance training on the psychological health of obese adolescents, researchers found that people in the resistance group experienced significantly greater self-esteem and perceived strength over four weeks. But what’s most interesting is that the feeling of getting stronger — rather than any measurable gains — was all it took to give them a boost.

Eating the right carbs is important too. Carbohydrate is stored in your body in the form of glycogen. Glycogen in the muscles is an important fuel reserve during intense physical exercise or in times of energy restriction – protein sparing. It is best to restrict or to keep away from junk carbohydrates such as sweets, cakes, and biscuits, and stick to foods like porridge, pasta (wholemeal), rice (brown), bread (wholegrain), and cereals (try to choose the versions with low or reduced sugar and salt). For more on carbohydrate and the effect of sugar on the body, click here.
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.

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]


While seasoned lifters may choose to do different exercises every day during a week-long period (and repeat the same moves the following week), there's no need to follow this type of program when you're just getting comfortable, says Davis. "Stick to the same basic moves two to three times a week to build a basic level of fitness and strength," says Davis. "Why complicate things if you don’t have to? Great results can be made by repeating the same workout but increasing weights as you become stronger." Switching things up can help you avoid a training plateau, explains Davis, but so can increasing weights while doing the same exercises.
So how does that play out in the real world? Well, if, for example, a woman adds 10 pounds of muscle and loses 10 pounds of fat, she’ll burn 40 extra calories per day. Forty calories a day isn’t nearly as significant as a dietary change could be, but for people who are looking to lose weight, it can still make a minor difference over the long term.
Competitive and professional bodybuilders, however, can often build up to two to three pounds of muscle per month during dedicated bulking periods. "But they are living and breathing muscle growth. They aren't just in and out of the gym like most people," Simpson says, noting that under extreme conditions, hyperplasia, or the growth in the number of muscle cells in a given muscle tissue, may actually occur, further adding to muscle growth results.
In nonelite swimmers conducting an intermittent sprint protocol (Six 50m sprints every two minutes), supplementation of a creatine loading period was able to reduce the decrement in speed during the third sprint (2% decrement rather than a 5% decrement) but not the sixth sprint. There were no changes in plasma lactate or other biomarkers of fatigue.[396] When examining a single 50m sprint in amateur swimmers, a creatine loading period is able to reduce the time to complete the sprint by 4.6%, while it had no benefit for the 100m sprint.[397] When the loading phase was followed by three weeks maintenance in youth, there was no apparent benefit to sprint performance (50m sprint with five minutes rest followed by a 100m freestyle) despite benefits to a swim bench test (30s sprints with a five minute break in between).[398]

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

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.


You don't need to design a fresh plan every three weeks. Scaling up weight and modifying reps are obviously both important for progression, but playing with different set styles will shock your body and keep things interesting. Remember, bodybuilding isn't meant to feel like a chore. Below, we explain eight different types of sets to help you build muscle more efficiently during bodybuilding training.

Put simply, "strength training means using resistance to create work for your muscles," says Hannah Davis, C.S.C.S. and author of Operation Bikini Body. So even if your mind jumps straight to those hardcore machines and massive weights, there are a lot of ways to create this resistance that require minimal equipment (or none at all). Bodyweight workouts can be an incredibly effective way to strength train. Squats and push-ups FTW. You can also use tools like dumbbells, medicine balls, TRX bands, resistance bands, kettlebells, and slider disks, to help get the job done, explains Davis. But if that sounds like gibberish don't worry about it. Keep it simple and focus on equipment-free routines first. No matter what you do, the most important thing is to find something that challenges you, says Davis.

In a sample of people with colorectal cancer given creatine supplementation for 8 weeks to assess its interactions with chemotherapy, creatine failed to benefit muscle function or quality of life. Benefits were observed in body cell mass and phase angle (indicative of cellular viability), but only in the subsample with less aggressive chemotherapy.[111]

Gain mass: One of the most popular reasons for people to take body building supplements is to gain weight and that is why protein powder is much sought after. Protein is the building block of muscles and therefore, bodybuilders use protein powder to help repair muscles, speed recoveries and preserve muscle mass. They usually consume 1 to 2 grams of protein per pound of body weight every day. 


Conflicting results have been obtained concerning the importance of testosterone in maintaining cardiovascular health.[29][30] Nevertheless, maintaining normal testosterone levels in elderly men has been shown to improve many parameters that are thought to reduce cardiovascular disease risk, such as increased lean body mass, decreased visceral fat mass, decreased total cholesterol, and glycemic control.[31]
If you're a beginner, just about any workout will be intense enough to increase protein synthesis. But if you've been lifting for a while, you'll build the most muscle quickest if you focus on the large muscle groups, like the chest, back, and legs. Add compound lifts like squats, deadlifts, pullups, bent-over rows, bench presses, dips, and military presses to your workout to work them the most efficiently.

The best way to know the real progress you’re making is by recording it on video or taking photos. “Photos mean everything because if you can take them in the same areas and in the same poses, you’ll see your strengths and weaknesses clearly,” says Heath. “Revise your training and diet programs to eliminate weaknesses.” Keep a file of your progress to see just how far you can take your fitness.


In people whose kidneys don’t function optimally, supplemental creatine seems to be safe, too.[513][518][313][528] However, studies in people with suboptimal kidney function are fewer than in healthy people, and they are short-term. People with kidney dysfunction, or at risk for developing kidney dysfunction (e.g., people with diabetes, high blood pressure, or family history of kidney disease; people over sixty; and non-Hispanic blacks), might wish to forgo creatine, or otherwise take only the lowest effective dose (3 g/day)[527] after talking to their doctor.
Creatine is a naturally occurring compound found in muscle in large amounts. Creatine monohydrate is the supplement form and combines is a combination of the amino acids arginine, glycine, and methionine. Creatine drives the important creatine phosphate energy pathway, which is important in high-intensity activity such as weightlifting. Creatine can improve body bulk and training performance in high-intensity activities. Be aware that not everyone responds to creatine supplementation and 30 percent of users may not see any improvement. Women may not benefit as much as men. In weight training, increased strength, bulk, and fat loss are reasonably consistent results.
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].

Aim to eat roughly 250 to 500 extra calories per day. To make sure that any weight gained is from muscle, Fitzgerald recommends that the bulk of those calories come from protein. In a 2014 Pennington Biomedical Research Center study, people who ate a high-calorie diet rich in protein stored about 45 percent of those calories as muscle, while those following a low-protein diet with the same number of calories stored 95 percent of those calories as fat.
Some ingredients found in dietary supplements marketed for bodybuilding or performance enhancement—such as whey protein, creatine, and caffeine—generally aren’t associated with any serious safety concerns (when used appropriately). However, they still have the potential for side effects. Before you take any dietary supplement, talk to your healthcare provider. You also can read the articles below about some of these ingredients:
Hook a velcro cuff to a low cable pulley and then attach the cuff to your right ankle. Face the weight stack from a distance of about two feet, grasping the frame for support. Keep your knees and hips bent slightly and your abs tight, contract your right glutes to kickback the leg. Slowly bring your working leg forward, resisting the pull of the cable until you reach the starting position. Repeat for required reps, then switch legs.
Chin-Ups. The chin-up is the easiest way to determine someone’s relative strength. If you can knock out sets of bench with your bodyweight but can’t perform at least 5 bodyweight chin-ups then it’s time to re-evaluate your priorities. Chin-ups are an excellent mass builder for the lats, biceps, and upper back so they should take the place of machine variations like lat pulldowns whenever possible.
In otherwise healthy bodybuilders, supplementation of creatine at 5g either immediately before or after a weight training session (with no directive on days without training) over the course of four weeks noted that while both groups improved, there was no significant difference between groups overall.[384] This null result has been found in another study with 0.1g/kg creatine thrice weekly over 12 weeks in otherwise healthy adults.[385] It has been suggested that post-workout timing may be favorable (based on magnitude-based inference) since more individuals experience benefits with post-workout when compared to pre-workout despite no whole-group differences.[384] 

Most people require around 20 calories per pound (or 44 kcal / kg) of bodyweight to gain muscle mass. Using a 180-pound (82kg) male as an example, the required daily calorie intake is 3600 calories (20 kcal x 180 lb = 3600 kcal). When it comes to gaining weight, it is likely that you may put on a few pounds of fat along the way, but if you do find your body fat increasing, either increase the amount of aerobic exercise (moderate intensity) you are doing or slightly reduce the total number of calories you are consuming. Remember you can’t force feed muscle gain!

Of course, cardio is an important part of fitness too, but the benefits of strength training are major. Strength training helps build muscle, and lean muscle is better at burning calories when the body is at rest, which is important whether you're trying to lose weight or maintain it. It also helps strengthens joints and bones, avoid injury, improve your muscular endurance, and will help you give it your all during your other workouts, whether that means setting a new PR if you're a runner or pushing (and pulling) a little harder with your legs during your favorite indoor cycling class.
Yes, you can pack on size while only doing bodyweight exercises – I did it while traveling the world – and gymnasts train mostly with bodyweight movements. However, this can feel like playing Halo on Legendary difficulty. It can be done, but damn it can be challenging – especially for lower body movements. If your sole goal is to get bigger as fast as possible, access to a barbell for squats and deadlift is almost a requirement.

COX-2, a pro-inflammatory enzyme, is sometimes a therapeutic target for both muscle soreness and some degenerative diseases that are exacerbated by inflammation. COX-2 inhibitors (in this study, rofecoxib) and creatine monohydrate both appear to protect dopaminergic neurons from being destroyed by toxins, and can protect in an additive manner, suggesting possible usage of both to reduce the risk of Parkinson’s disease.[230]
SAMe is the primary methyl donor in the human body, and supplements that preserve SAMe (such as trimethylglycine; TMG) promote a variety of benefits in the human body, like a reduction in homocysteine and reduced risk of fatty liver. Creatine has been implicated in both reducing homocysteine[124] and preventing fatty liver in rodents[125], thought to be secondary to preserving SAMe.
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]
“There is a lot of mixed research on creatine’s ability to improve muscle strength,” the government website says. “However, analyses of this research show that creatine seems to modestly improve upper body strength and lower body strength in both younger and older adults.” Creatine has also been shown to improve athletes’ performance in rowing, soccer, and jumping height.

Using too much weight, too soon; always start lower than your expected ability and work your way up that first workout. If your form suffers, you are swinging the weight, or using momentum, this indicates you may be using too much weight. Greater momentum increases the potential for injury and reduces the effectiveness to the muscle group being targeted.
In regard to practical interventions, concurrent glycogen loading has been noted to increase creatine stores by 37-46% regardless of whether the tissue was exercised prior to loading phase.[176] It is important to note, however, that creatine levels in response to the creatine loading protocol were compared in one glycogen-depleted leg to the contralateral control leg, which was not exercised.[176] This does not rule out a possible systemic exercise-driven increase in creatine uptake, and the increase in creatine noted above[176] was larger than typically seen with a loading protocol (usually in the 20-25% range). Consistent with an exercise-effect, others have reported that exercise itself increases creatine uptake into muscle, reporting 68% greater creatine uptake in an exercised limb, relative to 14% without exercise.[153]

I’ve previously written about Bacopa Monnieri and cocoa, two nootropics with strong studies showing their benefits in humans. Well, creatine is up there too. (In case you’re interested in specifics, on days each week when I need to be especially sharp I consume 350 mg Bacopa Monnieri, 75 g cocoa, and 5 g creatine monohydrate. It’s my favorite combination to date.)

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.”
Testosterone is an androgen hormone produced by the adrenal cortex, the testes (in men), and the ovaries (in women). It is often considered the primary male sex hormone. Testosterone stimulates the development of male secondary sex characteristics (like body hair and muscle growth) and is essential in the production of sperm. In women, testosterone plays a role in egg development and ovulation.
Testicular diseases which may cause low T include inherited conditions such as undescended testis, Klinefelter’s syndrome, and acquired conditions such as Mump’s orchitis, trauma to the testicles, and damage caused by cancer treatment. Conditions which may affect the regulatory functions of the hypothalamus and pituitary gland include medications such as opioid pain medications and steroids, kidney failure, tumors, tuberculosis, sarcoidosis, HIV/AIDS, obesity, and physical or emotional stress.
It doesn’t get more natural than getting a good night’s sleep. Research published in the Journal of the American Medical Association showed that lack of sleep can greatly reduce a healthy young man’s testosterone levels. That effect is clear after only one week of reduced sleep. Testosterone levels were particularly low between 2 and 10 p.m. on sleep-restricted days. Study participants also reported a decreased sense of wellbeing as their blood testosterone levels dropped.
