You can get a good idea of your primary body type simply by looking in the mirror: is your body shape tall and slender (ecto), round and thick (endo) or aesthetic and athletic (meso)? Many studies even go by photos rather than physical measurements in person. Unless you’re an exercise scientist, there’s no need for this level of detail. This requires measuring various body dimensions with a measurement tape and mathematical formulas to compute the 3 dimensions. The most established somatotyping method is the Heath-Carter method. What’s your somatotype: endomorph, ectomorph or mesomorph? What does your somatotype tell you about how you should work out and diet? Let’s look at the science of somatotyping.
ENDO ECTOMORPH DIET SKIN
The 3 body type dimensions are named after the 3 layers of germ during our embryonic development: the inner endoderm develops primarily into our gut the middle mesoderm develops primarily into our muscles, and the outer ectoderm develops into other things like our skin and hair. Mesomorphs have the best of both worlds.Ectomorphs are tall and skinny hardgainers that effortlessly get ripped but have a hard time putting on muscle.Endomorphs are bulky: they have an easy time gaining muscle and strength but a hard time losing fat.Popular fitness wisdom holds that your primary body type dictates what you’re gifted at and possibly also how you should work out and diet.


Other scientists of course quickly discredited these ideas, but exercise scientists picked up on the classification.

Sheldon’s original works tried to connect our somatotype to our personality and some Nazi-like ideas of human worth. He found that our structure can be summarized on 3 dimensions: endomorphy, ectomorphy and mesomorphy. In the 1940s, psychologist William Herbert Sheldon used thousands of photos of naked Ivy League students without their consent to create a classification of the human body shape.
