The 3 Body Types: Ectomorph, Mesomorph, and Endomorph

Did you know that our bodies are pre-determined to have different shapes? That “big boned” is actually a thing? Well, read and learn, my friends, read and learn…

Ectomorph, mesomorph, endomorph. Those three words may not mean a lot to you now, but they are about to.


Ectomorphs tend to be tall and lean. (Think models.)

With a thin build and long limbs, it tends to be harder for ectomorphs to gain weight, but that doesn’t mean they can become unhealthy. Ectomorphs simply have an incredibly high metabolism and a small frame.

To stay healthy and fit, ectomorphs should lift heavier weights with fewer reps with less cardio and eat foods with high protein to fat ratios (like almonds, avocado, and peanut butter).

Mesomorphs have both a larger body frame (like the endomorph) and the low body fat (like the ectomorph). They tend to be naturally muscularly toned individuals.

With a more “symmetrical” build, this body type tend to both put on muscle and lose fat easily. They’ll have a more athletic build (think swimmer’s body), with narrow waists and wide shoulders.

To stay healthy and fit, mesomorphs should do a mixture of resistance and cardio training, and eat enough calories throughout the day to maintain muscle mass.


Endomorphs are blockier and big boned.

Typically, these individual will have thicker rib cages and shorter limbs. They’ll find it hard to lose weight, try as they may. With larger frames, they’ll find they gain weight easily with a much slower metabolism than their ectomorph counterpart.

To stay healthy and fit, endomorphs should do as much cardio as possible and try to portion meals, as well as eat 5-6 smaller meals every day.

Typically, we’ll all be a mixture of at least two of these body types. Interested in what kind of body type you have? Take the quiz here.
