Just a quick question, sorry to pull another one of these up. Ive noticed some boxers tend to do push ups with clenched fists rather than flat palmed, whats the benefit? I knocked out a couple and im guessing its working out the muscles in the hand and triceps more than usual, however it seemed an easier/more natural movement in the arms and shoulders. So does it work out different muscles at different levels? If so is it worth swapping between flat palmed and clenched fist position? Or does doing it with clenched fists work out the same muscles to the same level but adding on the hand? Also is there any difference between doing it with your finger tips tucked in with your hand in a figure 6 shape or tips out in a U shape?
