Pull-ups are no easy feat for me. I have dumb long ass monkey arms. So I have a greater distance to travel. I can’t change that. But I’ve made it a point to work very hard at doing them regardless. There are alot of things about your physique that you can’t change (genetically) but what you can do is make the most of what you were given and strive to be the best version of yourself. Don’t see your shortcomings as a disadvantage but rather a reason to strive to be better than you were yesterday.
