Samatotypes are a way of measuring body build or physique. There are three samatotypes; endomorph (fatness), ectomorph (thinness) and mesomorph (mascularity). The measurements are taken for height, weight, bone size, muscle girth and fat so a persons samatotype might be 2.6.2 which is 2/7 for fat, 6/7 for muscle and 2/7 for thinness.
