Boxers often have a muscular back but I don’t know how it helps generate power. (English is not my first language, so sorry if I wrote something wrong)
In: Biology
A really solid punch starts in your feet. You push off your back foot, meaning your whole body is moving forward. Then you twist at the waist and back, pushing your shoulder forward faster. Then your shoulder and arm muscles punch forward, but they already have speed and force behind them. Everything adds up.
