RE: POWER CLEAN or DEADLIFT?????
well if you are already doing a lot of sprinting, which is basically power work, then I would do SLDL for your hams. DL arent really recommended for sprinting cos they are very taxing with a limited carryover to actual running. squats and SLDL would be my idea. the 2 components are increase in max strength and increase in power output. sprinting should take care of the power output, so you should use max strength exs. If you feel you should use power cleans, then do, but I wouldnt use DL if you dont.
