Our body size and structure reflects not only our eating and exercise habits but also our genetics. The role this latter factor plays in determining weight seems to vary greatly between individuals. We are all born with a certain body type inherited from our parents. Ectomorphs have a light build with slight muscular development. They are usually tall and thin with small frames and narrow hips and shoulders.
Mesomorphs have a husky, muscular build.
They often have broad shoulders, and their weight is concentrated in the upper body, making them look compact or stocky. Endomorphs are characterized by a heavy, rounded build with shoulders usually narrower than their hips. They have a round, soft appearance and are more often overweight or obese. When we understand and appreciate our bodies, we are able to work with them, not against them. Although many of us are a combination of two body types, we cannot become what we are not.
