Body Types: Are You an Ectomorph, Mesomorph, or Endomorph?

A body type, or somatotype, is a broad classification based on your natural frame, muscle development, and tendency to gain or lose body fat. Rather than placing people into strict categories, think of these body types as a spectrum.

Understanding your natural tendencies may help you make more realistic fitness and nutrition choices, but it shouldn’t limit your expectations. With consistent habits, people of every body type can improve strength, endurance, and overall health.
