Difference Between Ectomorph, Mesomorph, and Endomorph

Ectomorph, Mesomorph, and Endomorph are three different body types. The major differences between these categories are body size and structure.

In general, genetics, lifestyle, and history are the most vital factors in determining our body type. Disciplined exercise and dieting can help individuals change their body types. It is a continuous process that requires determination and willpower.

Ectomorphs possess thin bodies. They have small muscle bellies and long limbs. Their shoulders are less wide and thin. Additionally, they have lean muscles and small joints. Ectomorphs have a fast metabolism and burn calories quickly, making it difficult for them to gain weight.

In addition, ectomorphs are also termed, hard gainers.


The second body type, between ectomorph and endomorph, is mesomorph. Mesomorphs have a narrow waist, wide shoulder, round muscle bellies, comparatively thin joints. This body type is naturally muscular and strong.

They tend to have a shorter build, consisting of thick arms and short limbs. They also have wide hips and a thick ribcage.

Likewise, mesomorphs, this body type is fit and strong naturally.

In addition, the metabolism is slow.
