i have different shaped pectorals to my older brother. his are square and rounded a bit down the bottom whereas mine are shorter and more angled on the sides.
can anyone explain to me why we have different pectoral shapes? is it to do with genetics or with how we work out?
Pectorals grow the same shape in every person. If your's look different than his, then it means that one of you has either more muscle tone, muscle mass, different relative sizes of surrounding muscles, or fat surrounding the area, all of which can alter the appearance of any muscle.
