1) FUCK u
2) people with a lot of upper body strength tend to have smaller chests. when you gain muscle your upper body, breast tissue is replaced by muscle, making the chest appear to be smaller. if you look at afab olympic swimmers, you’ll notice that they generally have small chests and larger shoulders. it’s because of how strong your upper body has to be in order to do the strokes. peter does a lot with his upper body and obviously has a lot of muscle in that area. if he had a small chest to begin with, the added exercise could have made his chest look very flat.
