The terms ectomorph, mesomorph, and endomorph are old body-type categories called “somatotypes.” They describe general body tendencies, but real people are usually a mix rather than fitting perfectly into one type.
The 3 Somatotypes
Ectomorph
Typically:
- Slim build
- Narrow shoulders/hips
- Faster metabolism tendencies
- Harder time gaining weight or muscle
Mesomorph
Typically:
- Naturally muscular or athletic build
- Broader shoulders
- Gains muscle more easily
Endomorph
Typically:
- Softer or rounder build
- Gains weight more easily
- May store fat more readily
Important Things to Know
- These categories are simplified and not strict science.
- Your health depends more on:
- sleep,
- nutrition,
- exercise,
- stress,
- and genetics.
- Body shape does not determine worth, attractiveness, or athletic potential.
Most people are combinations like:
- ecto-mesomorph,
- meso-endomorph, etc.
If you want, I can also explain:
- workout styles often recommended for each type,
- nutrition basics,
- or how accurate somatotypes really are scientifically.
