ectomorph 

The "hard gainer" of the fitness world since they have a hard time building muscle although it is not impossible.

They're naturally small built with long, lightly muscular limbs. The have a fast metabolism so the can stuff their faces without putting on weight.

To gain muscle they need to eat alot and do heavy weight training, its advised that they avoid cardiovascular activities since cardiovascular activities burn fat

Examples of ectomorphs are Lisa Kudrow, Kate Moss, Brad Pitt, Seth Green, Edward Norton and most NBA players

ectomorph 

Scrawny individual who has a difficult time putting on mass or gaining weight. Often used as a condescending term among weight-lifters to describe skinny, and thereby weaker, males. In the bodybuilding terminology, the antonym of ectomorph is endomorph - which is a fatter or heavier set individual who conversely has a difficult time losing weight.

Kevin: Look at that ectomorph over there Keith, he's about as skinny as a twig!
Keith: Yeah I would help him out, but I don't care. He can do whatever the F**K he wanna do!
