EDIT: Sry for the title, not a weight belt for dips or chins, a belt for bench/squats.
I really dont understand how this helps people in any exercises. Im sorry, Im a noob. Ive thought about it a lot and I just cant get it to make any sense. Ive seen people using them before and I still cant figure it out. Could someone explain to me how it helps you lift more?
Also, if anyone could explain any of the other devices and how they help you to lift more, itd be appreciated.
