I remember haye being criticised years ago (around the time of the Thompson loss) for his training methods. He was training in swanky gyms lifting loads of weights. I think it showed he was neglecting the boxing training but he does look to have improved. I dont think his stamina is amazing by any means but its a vast improvement on what it was.

Lets not forget, Klitschko does 12 rounds and makes it look easy but it's not the same when his fights are usually 1 way traffic after a few rounds. See if he starts running out of gas a bit quicker than usual and start to lose his composure.

Who here has boxed? Surely you have had sparring sessions where you are on top for the majority and you must know it's a lot easier than where you actually have someone battling back at you
