I'm doing overhead press excercises with a loose heavy bag. It only weighs 39 pounds so I'm not at any risk of pulling a muscle or injuring my back.
But... does it do any good for a boxer? All I care about his shoulder strength.
Which parts of the body are at work in this excercise? And which one is working the most?
