I’ve always said, "if you’re trying to build strength, train like a powerlifter and/or a strongman. If you’re trying to buildi mass, train and eat like a bodybuilder. If you’re trying to develop explosive strength and power, train like an olympic lifter/jumper/shotputter. Obviously, there’s a little tongue in cheek with that statement, but there’s truth in at as well.
And again, as far as lifting too heavy while sprinting, Charlie has said many times the benchpress is not overly demanding on the CNS, and you don’t run with your legs. I would be more in line with Pioneer if you were talking about your squat, but since its your bench, and you’re not a sprinter, you have alot of off season pre-season to work on strength and mass without interfering too much with your sprint training.
