Ectomorph
- •Lean and long-limbed
- •Fast metabolism
- •Difficulty gaining weight
- •Narrow shoulders and hips
Focus on heavy compound lifts, eat in a calorie surplus, and prioritize protein. The body type calculator identifies ectomorphs so they can adjust nutrition upward.
Mesomorph
- •Naturally muscular
- •Medium frame
- •Gains muscle easily
- •Athletic build
Mesomorphs respond well to most training styles. Moderate calories with balanced macros work well. The body type calculator shows mesomorphs their natural advantage.
Endomorph
- •Wider build
- •Stores fat easily
- •Strong lower body
- •Slower metabolism
Emphasize metabolic conditioning and strength training. A slight calorie deficit with higher protein helps manage body composition. The body type calculator helps endomorphs focus their approach.
The Science Behind Body Types
The somatotype system was developed by psychologist William Sheldon in the 1940s. While the original theory linked body type to personality traits (which has been debunked), the physical classification remains useful for fitness and nutrition planning. Modern sports science recognizes that most people are a combination of two body types — a body type calculator shows your dominant and secondary type. The key insight is that body type reflects natural tendencies, not fixed outcomes. An ectomorph who trains consistently can build impressive muscle mass. An endomorph with the right nutrition plan can achieve very low body fat. Use the free body type calculator as a starting point for understanding your body, not as a label that limits your potential.
