Mésomorphe équilibré

The balanced mesomorph is what most people picture when they hear the word athlete: square shoulders, thick limbs, low bodyfat, no extreme linearity. Endomorphy and ectomorphy sit roughly equal and both below mesomorphy.

This is the type that recurs across the broadest range of high-performance sports — football, gymnastics, rowing, decathlon, mixed martial arts. It tolerates training volume well, recovers quickly, and gives the appearance of being designed for athletic work.

The Manu tribe — studied in early physical anthropology as one of the most uniformly mesomorphic populations ever recorded — fall into this type, as do most male bodybuilders at competition lean (where endomorphy drops but mesomorphy stays very high).

The 'balanced' in the name refers to the relationship between the other two components, not to overall body balance. A balanced mesomorph is not in the middle of the triangle — they sit close to the mesomorph corner with a small base.
