Ok, so there's a chin up bar right by a wall, which is often used for women to do their ball squats. I once had a woman ask me how much I have to go for chins because she needed to "squat." I don't watch, but I don't see them there for long, apart from doing maybe a few sets of 12 at bodyweight. How can that help anyone, even a woman, improve quad strength? It's fashionable as hell, but seems pointless if you're only using bodyweight for a few sets of 12.
