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. 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.
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.
If you’re the kind of person who shops for popular dietary supplements like protein or collagen powder, you’ve probably seen another popular bottle on the shelves: creatine. This supplement, which can be taken as a powder or liquid (and usually in some kind of healthy shake), is a staple in the bodybuilding community thanks to its ability to help you pack on muscle and work out longer and harder. (1) While creatine is generally considered safe — and is one of the most researched supplements out there (according to a review published in July 2012 in the Journal of the International Society of Sports Nutrition) — it is still a supplement, which means it’s not regulated by the Food and Drug Administration (FDA) and product claims don’t necessarily need to be substantiated (though the FDA can pull products that are found to be unsafe).

In the modern bodybuilding industry, the term "professional" generally means a bodybuilder who has won qualifying competitions as an amateur and has earned a "pro card" from their respective organization. Professionals earn the right to compete in competitions that include monetary prizes. A pro card also prohibits the athlete from competing in federations other than the one from which they have received the pro card. Depending on the level of success, these bodybuilders may receive monetary compensation from sponsors, much like athletes in other sports.
When it comes to finding the right meal plan, you have to start somewhere. Start with writing down what you eat in a food diary, calculate the calories you’re consuming daily (ex: 3,000 without protein shakes), and break those up into six meals (ex: 500 calories each), says Heath. Then, choose a macronutrient ratio. For example, the 40% protein, 40% carbs, 20% fat ratio is what Heath used to get bigger when he first started bodybuilding. “Buy a food scale, learn how to use it, and you may even have to learn to use the metric system, like grams instead of ounces,” Heath says. “You need to train your body to process food quickly, so eat every three hours.”
Today I want to share with you some quality advice on how to gain weight. Now I caution you that this is for the really skinny guy looking to really gain weight because they barely have any meat on their bones. I know what it is like when you feel like you eat all the time and have nothing to show for it. I have been there. I also understand the feelings that you feel when people start to resent you because you can eat whatever you want and not ever gain a pound. They don't realize that to skinny guys, this is a curse more than it is a blessing at times.

Nitrate-rich foods like beets, radishes, and pomegranates are a great way to boost the production of nitric oxide (NO). Although there's very limited research examining the effects of beet root juice and pomegranate extract on resistance training, these ingredients have previously been shown to increase skeletal muscle blood flow and lead to reduced soreness, which may ultimately lead to improvements in strength and performance.[9,10]
Although creatine supplementation has been shown to be more effective on predominantly anaerobic intermittent exercise, there is some evidence of its positive effects on endurance activities. Branch  highlights that endurance activities lasting more than 150s rely on oxidative phosphorylation as primary energy system supplier. From this meta analysis , it would appear that the ergogenic potential for creatine supplementation on predominantly aerobic endurance exercise diminishes as the duration of the activity increases over 150s. However it is suggested that creatine supplementation may cause a change in substrate utilization during aerobic activity possibly leading to an increase in steady state endurance performance.
Bodybuilding developed in the late 19th century, promoted in England by German Eugen Sandow, now considered as the "Father of Bodybuilding". He allowed audiences to enjoy viewing his physique in "muscle display performances". Although audiences were thrilled to see a well-developed physique, the men simply displayed their bodies as part of strength demonstrations or wrestling matches. Sandow had a stage show built around these displays through his manager, Florenz Ziegfeld. The Oscar-winning 1936 musical film The Great Ziegfeld depicts the beginning of modern bodybuilding, when Sandow began to display his body for carnivals.
Bodybuilders may supplement their diets with protein for reasons of convenience, lower cost (relative to meat and fish products), ease of preparation, and to avoid the concurrent consumption of carbohydrates and fats. Additionally, some argue that bodybuilders, by virtue of their unique training and goals, require higher-than-average quantities of protein to support maximal muscle growth. However, there is no scientific consensus for bodybuilders to consume more protein than the recommended dietary allowance. Protein supplements are sold in ready-to-drink shakes, bars, meal replacement products (see below), bites, oats, gels and powders. Protein powders are the most popular and may have flavoring added for palatability. The powder is usually mixed with water, milk or fruit juice and is generally consumed immediately before and after exercising or in place of a meal. The sources of protein are as follows and differ in protein quality depending on their amino acid profile and digestibility:
You may be wondering what conditions and medications contraindicate the use of creatine supplements. Creatine is contraindicated in people with kidney insufficiency or kidney disease. If you take diabetes medication, diuretics or acetaminophen, do not take a creatine supplement. Use caution if you regularly consume caffeine while taking a creatine supplement. Overall, if you are healthy and have gotten clearance from your doctor, consider this non-GMO creatine supplement.
In regard to the blood brain barrier (BBB), which is a tightly woven mesh of non-fenestrated microcapillary endothelial cells (MCECs) that prevents passive diffusion of many water-soluble or large compounds into the brain, creatine can be taken into the brain via the SLC6A8 transporter. In contrast, the creatine precursor (guanidinoacetate, or GAA) only appears to enter this transporter during creatine deficiency. More creatine is taken up than effluxed, and more GAA is effluxed rather than taken up, suggesting that creatine utilization in the brain from blood-borne sources is the major source of neural creatine. However, “capable of passage” differs from “unregulated passage” and creatine appears to have tightly regulated entry into the brain in vivo. After injecting rats with a large dose of creatine, creatine levels increased and plateaued at 70uM above baseline levels. These baseline levels are about 10mM, so this equates to an 0.7% increase when superloaded. These kinetics may be a reason for the relative lack of neural effects of creatine supplementation in creatine sufficient populations.
For the sake of mental focus, it’s best to keep any carbs you eat low during the day when you’re working and active and get the lion’s share of them at night with dinner. A typical breakfast could include eggs, yogurt, and fruit, or a shake, and lunch could be meat or fish and steamed veggies. For dinner, have meat or fish again, along with sweet potatoes or rice, and vegetables.

Creatine has been investigated for its effects on depression, due to the significant changes occurring in brain morphology and neuronal structure associated with depression and low brain bioenergetic turnover in depression, perhaps related to abnormal mitochondrial functioning, which reduces available energy for the brain. The general association of low or otherwise impaired phosphate energy systems (of which creatine forms the energetic basis of) with depression, has been noted previously. Due to associations with cellular death and impaired bioenergetics with depression, creatine was subsequently investigated.
A proper warm-up is an important part of an effective strength workout. Start by foam rolling your muscles to wake 'em up. "Foam rolling loosens up tight muscles so that they work the way they're designed to," says Davis. A dynamic warm-up is another important part of your pre-workout routine, it preps your muscles for the work they're about to do and helps increase your range of motion. Increasing your range of motion allows you to go deeper into those squats and fully extend those bicep curls, which means more muscle recruitment and better results. "These two combined reduce your risk of injury and allow you to push harder during your workout," says Davis. Get started with this five-minute warm-up.
Bodybuilding supplements are dietary supplements commonly used by those involved in bodybuilding, weightlifting, mixed martial arts, and athletics for the purpose of facilitating an increase in lean body mass. The intent is to increase muscle, increase body weight, improve athletic performance, and for some sports, to simultaneously decrease percent body fat so as to create better muscle definition. Among the most widely used are high protein drinks, branched-chain amino acids (BCAA), glutamine, arginine, essential fatty acids, creatine, HMB, and weight loss products. Supplements are sold either as single ingredient preparations or in the form of "stacks" – proprietary blends of various supplements marketed as offering synergistic advantages. While many bodybuilding supplements are also consumed by the general public the frequency of use will differ when used specifically by bodybuilders. One 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/kg of 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 kg for all trials and 1.0–2.0 kg, for protein intake ≥1.6 g/kg/day.
2-4 Minutes Rest: Ideal for “tension exercises,” which includes most primary compound exercises. I personally take 3 minutes for the big stuff, sometimes going into the 3-4 minute range depending on exactly what I’m doing and what I feel like I need at the time. Since making strength gains is the main focus of these exercises, longer rest periods like this will be optimal for making it happen.
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.)

Mini Reviews in Medicinal Chemistry. 16 (1): 12–8. doi:10.2174/1389557515666150722102613. PMID 26202197. The process of creatine synthesis occurs in two steps, catalyzed by L-arginine:glycine amidinotransferase (AGAT) and guanidinoacetate N-methyltransferase (GAMT), which take place mainly in kidney and liver, respectively. This molecule plays an important energy/pH buffer function in tissues, and to guarantee the maintenance of its total body pool, the lost creatine must be replaced from diet or de novo synthesis.
Creatine is normally metabolized into creatinine (note the difference in spelling), which is eliminated by the kidneys under normal conditions. When the kidneys fail and cannot clear the blood as effectively, many metabolites get “backlogged” in the blood. Creatinine is easy to measure and as such it is a biomarker of kidney damage. If serum creatinine levels are elevated, the doctor may suspect some kidney damage. Low-dose creatine (≤5 g/day) may not cause alterations in this biomarker in otherwise normal adults but high doses of supplemental creatine may cause a false positive (an increase in creatinine, due to creatine turning into creatinine, which does not signify kidney damage) and is a diagnostic error. Most studies, however, have noted only a small increase in creatinine levels even with doses ≈20 g/day.
One study on 27 otherwise healthy men supplementing creatine (0.3g/kg loading for a week, 0.05g/kg thereafter for 8 weeks) with a thrice weekly exercise regiment noted that alongside greater increase in lean mass and power relative to placebo at 4 and 8 weeks, myostatin in serum decreased to a greater extent with creatine (around 17% at 8 weeks, derived from graph) than it did with placebo (approximately 7%). Increases in GASP-1, a serum protein that inhibits the actions of myostatin by directly binding to it, were not different between groups.
Warm up sets are also important. For example, the same lifter working on his chest would also be advised to complete at least two warm up sets prior to hitting his "core tonnage." Core tonnage refers to the heavier lifts that actually strain your muscles. For example, if the lifter's main sets were at 205 lbs, 225 lbs and 235 lbs on the bench, then a warmup of 5 reps of 135 and 5 reps of 185 would be advisable. Some lifters will warm up with a 50/50 set for example 50% of the target weight for 50% of the target repetitions. When properly warmed up the lifter will then have more strength and stamina since the blood has begun to flow to the muscle groups.

Multivitamin supplements may help you reach the recommended daily intakes for vitamins and minerals if you have a less than ideal diet, travel impairs your diet, or strenuous exercise increases requirements. I consider a multivitamin good insurance in these circumstances against possible deficiencies. Choose a reputable brand. You should choose a good all-around supplement with a balanced formula.
In regard to the loading period, two reviews suggest that the range of weight gain associated with creatine supplementation at 20g for 7 days is in the range of 0.9-1.8kg (1.98-3.96lbs). The highest reported increase in water weight associated with creatine loading, although measured a month after loading started (after a maintenance phase) was 3.8kg (8.36lbs).
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.
The major controversies regarding creatine are its side effects and the best form to use. Nearly all side effects attributed to creatine, such as muscle cramps, kidney disease and gastrointestinal disturbances, haven't proved significant under controlled scientific scrutiny. Although various claims are made for a variety of creatine supplements, creatine monohydrate, which is 99 percent absorbed, is the best form to use.
One study investigating the effects of creatine supplementation on people with osteoarthritis undergoing knee arthroplasty (surgical procedure for osteoarthritis), who received creatine at 10g daily for 10 days prior to surgery and 5g daily for a month afterward, failed to find benefit with supplementation. This study failed to find any differences in muscular creatine stores or weight changes.
Exercise is highly effective in increasing your lean body mass, which is essentially muscle. In a study published in 2012, progressive resistance training helped men ages 50 to 83 gain an average of 2.4 pounds of lean body mass over an average of 20.5 weeks. Progressive resistance training involves performing weight bearing exercises. In addition, you must slowly increase the challenge of the exercise over time by increasing the weight, reps and/or sets. Studies show that either increasing reps or weight amount will work. So, if you don’t want to lift more weight, you can just do more reps and still build muscle.
In isolated striatal cells (expressing creatine kinase), seven day incubation of 5mM creatine (maximal effective dose) appears to increase the density of GABAergic neurons and DARPP-32 (biomarker for spiny neurons) with only a minor overall trend for all cells and showed increased GABA uptake into these cells, as well as providing protection against oxygen and glucose deprivation.
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 .
You can't scroll through Instagram without clocking a mammoth cheat day feast, but are real-life bodybuilders consuming such a crazy amount of calories every couple of weeks? Not quite. When he’s dieting for a competition, Terry incorporates ‘re-feed days’ into his schedule. This means he eats the exact same food, but essentially doubles the portion sizes.
Syrotuik and Bell  investigated the physical characteristics of responder and non-responder subjects to creatine supplementation in recreationally resistance trained men with no history of CM usage. The supplement group was asked to ingest a loading dosage of 0.3 g/kg/d for 5 days. The physiological characteristics of responders were classified using Greenhaff et al  criterion of >20 mmol/kg dry weight increase in total intramuscular creatine and phosphocreatine and non responders as <10 mmol/kg dry weight increase, a third group labeled quasi responders were also used to classify participants who fell in between the previously mentioned groups (10-20 mmol/kg dry weight). Overall, the supplemented group showed a mean increase in total resting muscle creatine and phosphocreatine of 14.5% (from 111.12 ± 8.87 mmol/kg dry weight to 127.30 ± 9.69 mmol/kg dry weight) whilst the placebo group remained relatively unaffected (from 115.70 ± 14.99 mmol/kg dry weight to 111.74 ± 12.95 mmol/kg dry weight). However when looking at individual cases from the creatine group the results showed a variance in response. From the 11 males in the supplemented group, 3 participants were responders (mean increase of 29.5 mmol/kg dry weight or 27%), 5 quasi responders (mean increase of 14.9 mmol/kg dry weight or 13.6%) and 3 non-responders (mean increase of 5.1 mmol/kg dry weight or 4.8%). Using muscle biopsies of the vastus lateralis, a descending trend for groups and mean percentage fiber type was observed. Responders showed the greatest percentage of type II fibers followed by quasi responders and non-responders. The responder and quasi responder groups had an initial larger cross sectional area for type I, type IIa and type IIx fibers. The responder group also had the greatest mean increase in the cross sectional area of all the muscle fiber types measured (type I, type IIa and type IIx increased 320, 971 and 840 μm2 respectively) and non-responders the least (type I, type IIa and type IIx increased 60, 46 and 78 μm2 respectively). There was evidence of a descending trend for responders to have the highest percentage of type II fibers; furthermore, responders and quasi responders possessed the largest initial cross sectional area of type I, IIa and IIx fibers. Responders were seen to have the lowest initial levels of creatine and phosphocreatine. This has also been observed in a previous study  which found that subjects whose creatine levels were around 150 mmol/Kg dry mass did not have any increments in their creatine saturation due to creatine supplementation, neither did they experience any increases of creatine uptake, phosphocreatine resynthesis and performance. This would indicate a limit maximum size of the creatine pool.
Creatine is not an essential nutrient as it is naturally produced in the human body from the amino acids glycine and arginine, with an additional requirement for methionine to catalyze the transformation of guanidinoacetate to creatine. In the first step of the biosynthesis these two amino acids are combined by the enzyme arginine:glycine amidinotransferase (AGAT, EC:22.214.171.124) to form guanidinoacetate, which is then methylated by guanidinoacetate N-methyltransferase (GAMT, EC:126.96.36.199), using S-adenosyl methionine as the methyl donor. Creatine itself can be phosphorylated by creatine kinase to form phosphocreatine, which is used as an energy buffer in skeletal muscles and the brain.

When lifting to complete fatigue, it takes an average of two to five minutes for your muscles to rest for the next set. When using lighter weight and more repetitions, it takes between 30 seconds and a minute for your muscles to rest. For beginners, working to fatigue isn't necessary, and starting out too strong can lead to too much post-exercise soreness.
It’s perhaps best known for the aesthetic benefits. Creatine increases muscle size relatively quickly and while that’s in part due to an increase in muscle water content — a good thing, since it means we’re better hydrated — it does indeed appear to lead to actual hypertrophy over time. And bigger muscles aren’t just aesthetic: larger muscles can improve work capacity, explosiveness, fat oxidation, injury resilience, and recovery.
So it was popular then, but is it effective now? Just because something is popular doesn’t mean it works. In the case of creatine supplementation, however, you can be confident that increased muscle strength and less fatigue is possible. All thanks to a critical chemical reaction taking place in your muscle cells. Read on and learn how creatine works and why it lives up to that nostalgic ‘90s hype.
If you have hit a plateau, a good supplement could be all you need to pull yourself out of a slump and make the progress you want to be making. Creatine is widely known as the most effective sports supplement. Scientific studies have proven that creatine maximizes ATP production which is responsible for energy in your body. Essentially, creatine will give you more energy to allow you to do the things that will make you stronger.
HMB supplementation is claimed to build muscle size and strength and promote fat loss in conjunction with a strength program. Studies of HMB have shown some benefit to strength athletes in building muscle bulk but the benefits are relatively small and the cost of HMB is high. The effective dose seems to be 3 grams/day divided into 1 gram three times a day. Probably not worth taking. Beta-alanine is the new guy on the block and has not been evaluated sufficiently in my view. It may provide some advantage in high-intensity sports like weight training but it’s much too early to know that it does. Some early studies are flawed. Save your money or try creatine instead.
Minor liver lesions (grade I, no grade II or III, pathology not indicative of toxicity) have been studied in SOD1 G93A transgenic mice (a research model for amyotrophic lateral sclerosis or ALS, but used in this study to assess a state of chronic pro-oxidative stress) for 159 days with 2% of feed intake and in CD-1 rats (seen as normal) over 56 days with 0.025-0.5mg/kg in CD-1 mice, although in Sprague-Dawley rats (normal controls) there were no significant differences noted even after 2% of feed intake for 365 days. These observations appear to be due to the strain of the rodents used, and human studies on amyotrophic lateral sclerosis (ALS; what the SOD1 G93A transgenic mice are thought to represent) lasting from nine to sixteen months with subjects supplementing with up to 10g of creatine daily have failed to find any abnormalities in serum biomarkers of liver or kidney health.
The lower the rep range (and therefore the higher the intensity and the heavier the weight), the more rest there should be between sets. So most of the time, exercises being done in the 5-8 rep range need longer rest periods than exercises being done in the 8-10 rep range, which need longer rest periods than exercises being done in the 10-15 rep range.
To succeed and thrive as a bodybuilder, it takes more than overwhelming muscular strength or athletic prowess. Judges select bodybuilding champions based on muscle mass, definition, proportion, symmetry, and an athlete’s stage presence. Given the criteria, it is no surprise that most serious bodybuilders consider supplementation to be an essential component of their training regimen.
Wilkinson, S. B., Tarnopolsky, M. A., MacDonald, M. J., MacDonald, J. R., Armstrong, D., & Phillips, S. M. (2007). Consumption of fluid skim milk promotes greater muscle protein accretion after resistance exercise than does consumption of an isonitrogenous and isoenergetic soy-protein beverage. The American Journal of Clinical Nutrition, 85(4), 1031-1040.
Bodybuilders also train small muscles with a similar volume, frequency and intensity of their larger muscles. Strength athletes laugh at this. “Curls are a waste of time” is a common phrase you will hear hurled at a bodybuilder. This is SILLY. Although big compound movements should be most people’s resistance training priority, smaller muscle group focus work has some benefits for every athlete. Bicep tears are quite common among strength athletes, especially strong men and powerlifters. This happens because these competitors will lift tremendous weights with their backs, but their biceps are the weak link. Many of these injuries could be prevented with some good old-fashioned bodybuilder type isolation work. If you are only as strong as your weak link, doesn’t it make sense to make those weak links strong ones?
This muscle-building, power-enhancing supplement has an extremely high safety profile and a plethora of evidence to support its efficacy. Creatine supplementation works by increasing the availability of creatine and phosphocreatine (PCr) within the muscle, helping to maintain energy during high-intensity exercise such as weightlifting. Furthermore, increasing the availability of PCr may help speed up recovery between sets.
When assessing the antioxidant effects of creatine, it does not appear to sequester superoxide and may not be a direct antioxidant. Additionally, creatine failed to protect neurons from H2O2 incubation to induce cell death via pro-oxidative means. These results are in contrast to previously recorded results suggesting creatine acts as a direct anti-oxidant.
You may have heard hardcore lifters talk about things like "leg day," but when it comes to a beginner strength workout that's only a few days a week, a full-body workout is often the way to go (rather than splitting your days up by body part). "Full-body workouts maximize your caloric burn and the muscles worked each session," says Davis. The best way to do this is to pair one upper body exercise with one lower body exercise. "This way, the lower body has time to recover while the upper body works and vice-versa," says Davis. You should also aim for a balance between movements that feel like pulling and ones that feel like pushing. For example, Davis suggests pairing these exercises together:
The muscle endurance objective is pursued when you want your muscles to be able to perform the same motions over an extended period of time or in other words when you want your muscles to be strong and not become tired rapidly. You'll want to use at least 4 sets from which at least 16 repetitions are performed. The muscle endurance objective is often used for muscles in your lower body, such as those located in your legs or your buttocks.
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. Other performance-enhancing substances used by competitive bodybuilders include human growth hormone (HGH), which can cause acromegaly.
When it comes to building muscle, your body only knows or cares about the tension, fatigue and damage an exercise is generating… not the type of equipment you were using when performing that exercise. It really couldn’t give the slightest crap about that. For this reason, ALL types of exercises and ALL types of equipment are capable of stimulating muscle growth.
One pilot study using 150mg/kg creatine monohydrate for a five day loading phase followed by maintenance (60mg/kg) for the remainder of the five weeks noted that supplementation was associated with fewer muscle symptoms and complaints alongside improved muscular function, yet a later trial trying to replicate the obsevations using 150mg/kg daily for five weeks noted the opposite, that creatine supplementation exacerbated symptoms.
