I’ve been wondering how much upperbody strength can contribute to sprinting, so I’m going to ask a question here. Does anyone have any real evidence of the force produced by sprinters in the arms/deltoids, pecs, etc? Because I am really debating whether or not I should waste my time working out my rear deltoids.
you doubting the strong use of anecdotal support in here?
