Ectomorph

The extreme ectomorph physique is thin and linear. The bones are light, joints are small and muscles are slight. The limbs are long in proportion and lack muscle definition, though. The ectomorph is not naturally powerful and will have to work hard for every ounce of muscle and every bit of strength he or she can gain. An ectomorph can be described as lean, lightly muscled, small shouldered, thin.
