American psychologist, William Sheldon, popularized three broad categories of body in the 1940s, and since then, it has become widely accepted that men’s bodies generally fall into those three main categories (or types), and they are:
- Ectomorph: Lean and long, with difficulty building muscle
- Mesomorph: Muscular and well-built, with a high metabolism and responsive muscle cells
- Endomorph: Big, high body fat, often pear-shaped, with a high tendency to store body fat
We stumbled across a great article on the Coach Mag website on these body types, here. It covers everything from the physical characteristics of the different body types to how to eat and how to work out for your specific body type — and even goes into sleep, muscle recovery and hormone balance.
