murray can definitely bench press more than djokovic.
also, with his thick legs you'd think he leads in the squat department.
Negative, the hitting the forehand with power requires the pectorals as prime movers.
Murray's forehand is powder-puff, one can only conclude he'd suck at the bench press as well.
Being as weaponless as he is, gives you an indication that Murray is by far the weakest physically of the top 4.
