endomorphic

Endomorph, in the context of somatotype theory, refers to a body type characterized by higher relative body fat, a rounder or softer appearance, and a tendency toward weight gain. It is one of the three classic somatotypes proposed by psychologist William Sheldon in the 1940s (the others being ectomorph and mesomorph).

Typical features include a wider chest, hips and waist, a generally stockier frame, and a propensity to gain fat easily while muscle can be less pronounced on a lean body; fat distribution is often central in men and around the hips and thighs in women. Metabolic rate is a common assertion in popular discussions, but scientific support is mixed.

In sports and fitness, endomorph is used as a rough guide to tailor training and diet, emphasizing a higher emphasis on aerobic exercise, portion control, and resistance training to increase lean mass and metabolic rate; but individuals vary widely and there is no fixed rule.

Critique: The somatotype framework is considered oversimplified and reductionist; modern approaches emphasize that body composition depends on genetics, environment, and lifestyle, and that body types are not fixed or deterministic. Some sources discourage rigid categorization.
