The key phrase in this thread is Max Strength Phase, i.e. Increasing Max Strength. Even as a maintenance phase, I don’t believe 2-3 @ 75% would accomplish much. Some sprinters don’t lift at all during comp, but that doesn’t make no lifting the best way to increase max strength.
@ Pioneer. I agree that it may not take a large percentage of reps in near-max intensity range, but it takes some, or you will need to push harder in terms of the number of reps left in the bank. And again, I’m talking about a true Max Strength phase, not maintenance or comp phases.
