Know Your Bodybuilding Supplement - BCAA'sWritten by Rick Mitchell
BCAA stands for branched chain amino acids and is increasingly being recognized as an important supplement in field of sports nutrition. In short term refers to three essential amino acids - leucine, isoleucine and valine.Amino acids are widely known as building blocks of protein. When protein food is eaten it gets digested into individual amino acids and short chains of amino acids that are sufficiently small to be absorbed into bloodstream. They are then used by body to build and repair tissues amongst other things. Amino acids are split between those classed as essential and those labelled non-essential. This simply means that essential amino acids cannot be made by body, whereas non-essential amino acids can. There are nine essential amino acids and each must be obtained from diet. The nine essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine.

Unlike other body parts though, shoulder is not designed for heavy lifting in all directions so beginners need to take care and use lighter weights than usual for shoulder-isolating exercises.The deltoid covers shoulder and consists of three distinct segments: 1. The anterior or front deltoid allows you to raise your arm to front. 2. The medial or middle deltoid allows you to raise your arm to side. 3. The posterior or rear deltoid allows you to draw your arm backwards when it is perpendicular to torso. The front delt usually receives plenty of work with chest exercises such as bench press and pushup, so you'll need to use common sense and listen to your body when performing exercises that specifically target this muscle. The recommended shoulder exercises for beginners are as follows:
