In reply to nw:
im not sure. i think for real world applications (depending on what ones 'real world' is of course), power production needs to be progressively stretched out towards endurance. especially for something like a plyometric as it pretty rapidly hits a threshold - the next step is to make that threshold last longer (for endurance based stuff at least).
but yeah, its gotta be based off solid actual power production first.
i think what the 5/10 clap-push sort of thing does is train recovery as much as power, in the context of power.
and agree - shits n giggles is needed to keep things interesting.
