Body Types: Are You Ectomorph, Mesomorph, or Endomorph?
Discover the three main body types—ectomorph, mesomorph, and endomorph. Learn how to identify your body type and tailor fitness and nutrition for best results.
Introduction
Have you ever wondered why some people gain muscle easily, others stay lean no matter how much they eat, and some struggle with weight gain despite exercise? The answer may lie in body types, also known as somatotypes.
The three primary body types—ectomorph, mesomorph, and endomorph—help explain differences in body structure, metabolism, and response to diet and exercise. While most people are a mix of types, understanding your dominant somatotype can help you make smarter fitness, nutrition, and lifestyle choices.
In this article, we’ll break down each body type, how to identify yours, and how to optimize your health based on it.
What Are Body Types (Somatotypes)?
The concept of body types was introduced by psychologist William H. Sheldon. Somatotypes classify people based on:
-
Skeletal frame
-
Muscle mass
-
Fat distribution
Although modern science recognizes that genetics, hormones, and lifestyle play major roles, body types remain a useful framework for understanding physical tendencies.

How to Identify Your Body Type

Where do I store fat?

Your lifestyle, diet, and training can also shift how your body behaves over time.
