In humans, studies that investigate links between serotonin and creatine supplementation find that 21 trained males, given creatine via 22.8g creatine monohydrate (20g creatine equivalent) with 35g glucose, relative to a placebo of 160g glucose, was found to reduce the perception of fatigue in hot endurance training, possibly secondary to serotonergic modulation, specifically attentuating the increase of serotonin seen with exercise (normally seen to hinder exercise capacity in the heat[233]) while possibly increasing dopaminergic activity (conversely seen to benefit activity in the heat[234]).[155]
It’s not just about lifting—it’s about lifting safely and correctly. And if you’re not performing exercises properly, it’s impossible to make any progress. “When someone is just starting to work out, it can help to work closely with a knowledgeable personal trainer in order to learn proper form,” says Ingram. But that goes for experienced lifters, too. If you aren’t sure about a movement, it’s better to ask. “If you’re not working the correct muscles, you can’t expect them to grow,” explains Ingram.

Post workout, it’s important to restore your body’s energy by consuming protein and carbs. When you’re trying to build muscle, this is an especially important step. Protein powder is a great muscle builder for your post-workout routine, as long as you include a carbohydrate as well. You can get this by eating a banana or adding oats or banana to your protein shake. Or simply cook up a batch of healthy oatmeal muffins and include protein powder in your recipe. Then, enjoy your post-workout supplement as a delicious snack!
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.
Earlier during your workout, you might have thought you were starting to see some muscle definition. "Called transient hypertrophy, or a muscle pump, this physiological phenomenon occurs when blood rushes to your muscles to supply them with workout-powering fuel and even jump-start the recovery process," explains certified strength and conditioning specialist Samuel Simpson, co-owner and vice president of B-Fit Training Studio in Miami. He notes that this muscle pump often starts mid-workout and subsides within a few hours after leaving the gym. And as the muscle pump deflates, it's easy to lose determination.

It’s an amazing feeling when you graduate from lifting 10-pounders to 15-pounders. “Over time, you get better at something you’re doing, and you develop a sense of mastery and feeling that you’re getting stronger,” explains James Whitworth, a doctoral research fellow in the Biobehavioral Resistance Training Lab at Columbia’s Teachers College in New York City. “It helps your confidence, and that gives you a boost in self-esteem.”
Back in the 1970s, scientists discovered that taking creatine in supplement form might enhance physical performance. In the 1990s, athletes started to catch on, and creatine became a popular sports supplement. The supplement is particularly popular among high school, college, and professional athletes, especially football and hockey players, wrestlers, and gymnasts. 
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!
More recent studies on the regulation of CrT creatine transport activity have identified the protein kinase (Janus-Activating Kinase 2) JAK2, which suppresses the rate of creatine uptake via CrT without affecting creatine binding.[181] JAK2 is a regulatory protein involved in stabilizing the cellular membrane and controlling water concentrations in response to osmotic stress.[182][183] Similar to c-Src (a positive creatine transport regulator), Jak2 can also be activated by growth hormone signaling.[169][184] The growth hormone receptor seems to activate these two factors independently, as gh-mediated activation of c-Src does not require JAK2.[168] Given that c-Src is a positive regulator of CrT, JAK2 is a negative regulator, and the fact that downstream signals from both are induced by growth hormone, it is tempting to speculate that JAK2 activation downstream of the gh receptor may function as a homeostatic response to limit c-src induced creatine uptake. This has not been studied, however, and the effects of gh-induced JAK2 signaling on CrT activity have not been examined.
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 addition to ALL of the above, strength training is fun! Whether you are looking for the most effective 20-30 minute workout (to stay fit and look great naked), or are looking for a competitive sport that you can really get into, strength training can help you meet your goals. It’s easy and fun to see progress as you strength train, almost like leveling up. And if you’re looking to improve in other areas (a sport, traditional cardio, or an activity like rock climbing), strength training is an easy choice!

What you eat plays a big role in how much muscle your body can build. Proteins are especially important for building muscle. When you eat protein, your body breaks it down into amino acids which are the building blocks of muscle. How much protein you should include in your diet depends on a number of factors including your age and muscle building goals. Older adults who engage in resistance training and those hoping for maximum muscle growth should eat 1 to 1.3 grams of protein per kg of body weight (2, 3). If you weigh 150 lbs, that means you should take between 68 and 88 g of protein daily. Other recommendations are more modest, suggesting that .36 grams of protein per pound of body weight is enough.
Because the distribution of muscle strength is unique to each there is no short answer to this question. A personal trainer simply cannot tell all his/her customers to perform a bench press using 100 pounds because it will be too difficult for some and too easy for others. Rather the idea here is to use the right amount of weight that will make you successful in accomplishing the objective set previously (muscle power, strength or endurance).
A: First, you have to realize that when one is gaining weight it’s nearly impossible (steroid discussion aside) to gain solely muscle without the acquisition of some body fat as well. That being said though, you can improve thedistribution of lean body mass to fat mass by ensuring that your calorie consumption isn’t too aggressive (i.e. 1000+ over your BMR). Also, it should go without saying, but you need to be training hard while focusing on progressive overload to ensure that the calories you’re ingesting are actually going towards muscle growth. You shouldn’t be neglecting cardiovascular work either; both HIIT and LISS each play a role in enhancing mitochondrial density, balancing neurotransmitters, improving oxidative capacity, and influencing brain plasticity.

The muscle strength objective is pursued when you want your muscles to be effective when a high number of repetitions will be involved, or in other words when you want your muscles to be strong for a continued period of time. You'll want to use approximately 4 sets from which 10-12 reps are performed. The muscle strength objective is often used for muscles located in your back and your abdominals. 

Guanidoacetate (made by AGAT) then receives a methyl donation from S-adenosyl methionine via the enzyme guanidinoacetate methyltransferase (GAMT), which produces S-adenosylhomocysteine (as a byproduct) and creatine. Deficiencies in GAMT are more severe (although equally rare) relative to AGAT, resulting in severe mental retardation and autism-like symptoms.[31]
xEndurance’s Creatine-JB is a fantastic, all-natural creatine for athletes. It’s a little expensive at a dollar per serving, but it has a really pleasant citrus flavor and it contains a gram of lactate, which has been shown in some studies to improve time to exhaustion in short duration, high intensity workouts. It’s also third party tested by Labdoor and Informed Choice.

Another study found that one week of creatine supplementation at 25 g/day enhanced muscular performance during repeated sets of bench press and jump squat exercise. Creatine supplementation appeared to allow the subjects to complete their workouts at a higher intensity. The researchers concluded that, over time, working at higher intensities may provide a more intense training stimulus and improved muscular adaptations [10].

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]
Due to a combination of its neuroprotective effects and dopaminergic modulatory effects, creatine has been hypothesized in at least one review article to be of benefit to drug rehabilitation.[266] This study used parallels between drug abuse (usually methamphetamines) and traumatic brain injury[267][268] and made note of creatine being able to reduce symptoms of brain trauma, such as headaches, fatigue, and dizziness in clinical settings in two pilot studies.[269][270] No studies currently exist that examine creatine supplementation and drug rehabilitation.

A dose of 5g daily has strong evidence supporting it not causing any adverse side effects[605] and 10g has been used daily for 310 days in older adults (aged 57+/-11.1) with no significant differences from placebo.[519] Such a dose has also been demonstrated for long-term safety for people with Parkinson’s disease,[606] and at least one small retrospective study in athletes (surverying people taking creatine for up to or over a year) failed to find any significant differences in a battery of serum health parameters.[502] Other studies measuring serum parameters have also failed to find abnormalities outside the normal range.[607]

Getting comfortable with a steady running routine is definitely something to be proud of, but when you're on that cardio grind day-in and day-out, you might be ready to change things up and take on a new challenge. Time to throw some strength training into the mix. It can be a little intimidating at first if you don't know where the hell to start, but understanding the basics can help you feel confident in your refreshed fitness routine.


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. 

Key point: Past a certain number of sets, the marginal increases in protein synthesis NO LONGER outweigh the cost of doing more sets. If 8 sets of chest exercises produce 95% of possible muscle protein synthesis… then it makes very little sense to do ANOTHER 10 sets (like most chest workouts) to try and inch out the final 5% of stimulation. Those extra 10 sets are simply damaging your muscle unnecessarily and impairing your ability to recover.
According to the two meta-analyses on the topic, creatine significantly increases power when supplemented in both sexes over a period of time up to 8 weeks, during which improvement over placebo is maintained, rather than being enhanced further. The rate at which power is derived from a resistance training regimen appears to be up to 78.5% greater with creatine relative to placebo, and in active trained men who are naive to creatine, this can be quantified at about 7kg for the bench press and 10kg for the squat over 8 weeks.

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.”

A typical creatine supplementation protocol of either a loading phase of 20 to 25 g CM/d or 0.3 g CM/kg/d split into 4 to 5 daily intakes of 5 g each have been recommended to quickly saturate creatine stores in the skeletal muscle. However a more moderate protocol where several smaller doses of creatine are ingested along the day (20 intakes of 1 g every 30 min) could be a better approach to get a maximal saturation of the intramuscular creatine store. In order to keep the maximal saturation of body creatine, the loading phase must be followed by a maintenance period of 3-5 g CM/d or 0.03 g CM/kg/d. These strategies appear to be the most efficient way of saturating the muscles and benefitting from CM supplementation. However more recent research has shown CM supplementation at doses of 0.1 g/kg body weight combined with resistance training improves training adaptations at a cellular and sub-cellular level. Creatine retention by the body from supplementation appears to be promoted by about 25% from the simultaneous ingestion of carbohydrate and/or protein mediated through an increase in insulin secretion. This combination would produce a faster saturation rate but has not been shown to have a greater effect on performance.
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]
Cyclocreatine appears to be passively diffused through membranes and not subject to the creatine transporter, which can be beneficial for cases where creatine transporter function is compromised (creatine non-response and SLG6A8 deficiency). Similar to other forms of creatine, it buffers ATP concentrations, although its efficacy as a supplement in otherwise healthy people is currently unknown.
A: Let your symptoms be your guide. A slight sore throat or runny nose may require you to back off for a day or two but don’t confine yourself to your bed and assume the worst. However, you must also remember that prolonged, intense exercise can decrease immune function and make you more susceptible to bacterial and viral based sickness so it's equally as important to listen to your body and respond accordingly.

In recent years, the related areas of fitness and figure competition have increased in popularity, surpassing that of female bodybuilding, and have provided an alternative for women who choose not to develop the level of muscularity necessary for bodybuilding. McLish would closely resemble what is thought of today as a fitness and figure competitor, instead of what is now considered a female bodybuilder. Fitness competitions also have a gymnastic element to them. A study by the Clinical Journal of Sport Medicine found that female bodybuilders who are taking anabolic steroids are more likely to have qualified for substance dependence disorder, to have been diagnosed with a psychiatric illness, or to have a history of sexual abuse.[14]

A big clue is digestion. He does occasional cleanses. (“There’s no planes that week,” he said. “And no judgment at home.”) The slightest change in a muscle, just a stripe in a striation, is noticed. And while Heath does most workouts alone, he has a trainer, Hany Rambod, who is based in California. They see each other about once a month. In between, Heath sends photos and receives workout and dietary advice in return.
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. 
Glycogen synthesis is known to respond directly and positively to cellular swelling. This was demonstrated in an earlier study, during which rat muscle cells were exposed to a hypotonic solution in vitro to induce cell swelling, which increased glycogen synthesis by 75%. In contrast, exposing these same cells to a hypertonic solution hindered glycogen synthesis by 31%. These changes were not due to alterations in glucose uptake, but are blocked by hindering the PI3K/mTOR signaling pathway.[112] It was later noted that stress proteins of the MAPK class (p38 and JNK) as well as heat shock protein 27 (Hsp27) are activated in response to increasing osmolarity.[113][114] Furthermore, activation of MAPK signaling in skeletal muscle cells is known to induce myocyte differentiation[115] via GSK3β and MEF2 signaling, which can induce muscle cell growth.[116][117]

Great Paleo beef protein, why? Because it doesn't have any preservatives, fillers, Dairy, soy, yeast, corn, or any other additives. No artificial colorings/flavorings. That makes this product not just paleo, but also autoimmune paleo friendly, hard to find. That basically means anti alergic, you dont get the same digestive issues many people get with whey. I think beef protein is underrated, I just finished a batch and went back to my whey. The whey gives me bloating/gas that this product doesnt. Also if you don't like how the amino acid profile stacks up agains Whey protein powder you can add some BCAA to powder, at least thats what I do. In a 30 gram saving you get 28 grams of protein (zero fat and zero carb), not bad!
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.[503] These observations appear to be due to the strain of the rodents used,[504][503] 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.[505][506][507]
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
