What are the characteristics of an ectomorph body?

Ectomorphs are naturally slim. They remain relatively slim no matter how much food they eat or the types of food they consume. While ectomorphs can accumulate fats, their body's ability to do so is still much lower than others.

Ectomorphs burn calories fast, their hair usually grow long fast and they hardly gain weight as a result.

Ectomorphs develop muscles at a slower rate than other body types because of their high calorie burning rate. 

Ectomorphs usually have long limbs compared to someone of their same size.

Ectomorphs usually have small joints and bones. As a result, their overall body looks small.

Some people believe that Ectomorphs have a more powerful nervous system and that they are more likely to become emotionally sensitive than others.

Ectomorphs have smaller muscles than others unless they exercise regularly.

The most common sign of an ectomorph is his thin leg and wrist compared to others of his same age.

Ectomorphs have slim shoulders, chest and hips.

Because of their ruler-shaped-body, ectomorphs appear to be taller than they are.

Ectomorphs are more sensitive to temperature changes because their bodies don't have enough muscles and fat. Ectomorphs are usually the first people to complain about the temperature.

Ectomorphs can lose weight very fast if they started doing extra activities or if they changed their eating habits.

Ectomorphs can sometimes be hyperactive due to their fast metabolism and fast energy burning rate.

Ectomorphs have very low body fat compared to Mesmorphs or Endomorphs.

Ectomorphs can get very emotional sometimes because of their overly active nervous system. They usually experience things in an intense way and are more likely to get emotionally affected than the other body types.
