gotcha. yeah I'd agree to a certain extent, although I'd caveat with the following: the build-up to 90% of max with higher (5 and 3) reps and lower intensity works more like a warm-up for me, saving pop for the high weights.
I think also the idea with the lower weight reps is that you build a base upon which to develop more pop.
But I could see having days where one omits the build-up and goes straight to high after warm up. maybe a few week cycle or somesuch.
And then apply this to climbing specific work-outs too, such as campusing, system board, bouldering, etc.
Right on--good way to get at it.
But remember that when building endurance, we are not necessarily improving our muscle power. Developing fast twitch muscle response will have little impact on slow twitch muscle cells. But you are right to say that alternating your workouts gives a better overall result. And building tendon strength occurs during almost any lifting workout--and that translates to more strength in everything else you do.
Lifting rocks.
