Yes, I agree. But you misunderstand the basis of my post. Building strength in the legs will increase power. Throw out traditional bodybuilding routines. Heavy low rep squats will build the power and functionality. Go to a football training camp. These guys are squatting.

Take champion sprinter Maurice Green. This guy squats, and employs different weight ranges and techniques - pauses, explosive reps, 1 1/3 reps, negatives, etc.

I also like to see athletes use a higher rep range to hit all muscle fibers, especially the endurance fibers.
