A dipeptide protein of two amino acids (histidine and beta-alanine) produced naturally in the body. Carnosine is highly concentrated in the muscles (when under tension) and brain, but it also used by the heart, liver, and kidneys. It is believed to contribute significantly to muscle strength, muscle power, endurance, muscle growth, and possibly even fat loss. … Read more
A non-protein amino acid stabilized by a natural salt compound. Citrulline is the amino acid that is produced when another amino acid, ornithine, combines with carbamoyl phosphate during the urea cycle. Malic acid, or malate, is a natural salt compound found in fruit and other foods, and is often used as a food preservative. Supplementation … Read more
A grouping of sets where multiple exercises are performed in tandem without putting the weight down. A complex is a fast-paced form of weight training where you perform a sequence of back-to-back exercises without ever allowing the weight to hit the floor. Commonly referred to simply as a “complex”, the set will usually consist of … Read more
A grouping of sets where two exercises for the same muscle group are performed in tandem without rest. While a super-set trains opposing muscle movements, compound-sets use two different exercise to work the same muscle group. An example of this is a set of biceps curls followed immediately by a set a hammer curls with … Read more
The muscle movement (action) that occurs when the muscle force exceeds the resistance.
A non-essential protein-like compound found in muscle and the brain. It is synthesized in the liver from the two amino acids arginine and glycine, and then taken up from the bloodstream into the muscle where it becomes phosphocreatine. During exercise, phosphocreatine donates its high-energy phosphate molecule to create adenosine triphosphate (ATP), which is used by the muscle for … Read more
