Mésomorphe ectomorphique

The ectomorphic mesomorph has the muscle and bone of a mesomorph but with longer levers and less width — taller, thinner, more angular than the balanced mesomorph. Skinfolds are minimal.

This is the typical somatotype of the elite gymnast, the male swimmer, the road cyclist, the lightweight rower, the track sprinter. Power output is high but distributed across a leaner, longer frame. The body looks built more for repetition and reach than for collision.

Brahmin men in classical anthropometric surveys were grouped into this type; so are most male track cyclists and many high jumpers. The frame favours sports where leverage and strength-to-weight matter more than absolute mass.

Ectomorphic mesomorphs are often misclassified by laypeople as ectomorphs because of their height and visible vascularity — but their bone breadths and limb girths give them away. They build muscle readily; they just wear it differently.
