Somatotype refers to a particular build or type of body, based on physical characteristics. It is refers to Dr. William H. Sheldon "ectomorph" somatotype when he came up with the theory sometime in the 1940's. Sheldon's theory states that human bodies are divided into three main somatotypes; the ectomorph, the endomorph and the mesomorph. The ectomorph is the naturally skinny person who has trouble gaining weight, whether in the form of muscle or fat. The endomorph on the other hand has the opposite problem, it is too easy for a person with this body type to gain weight. While endomorphs are easy muscle gainers, provided they diet and train correctly, they are cursed with a slow metabolism, which makes it imperative that they be strict with their diet year round if they wish to have any abdominal definition. The mesomorph, however, is the naturally muscular person, who also has a higher metabolism than the endomorph. Mesomorphs make excellent bodybuilders and for them, gains in muscle and reduction in body fat come rather easily provided they maintain a great training and nutrition program. Somatotyping was first applied to criminology by William Sheldon and Eleanor and Sheldon Glueck.
