Metabolic Acceleration Training

Alwyn Cosgrove writes about it here.

I've been doing circuits for the past few months and it's too bad I didn't read this first (because it would've been nice having some rest in those circuits!)... Alwyn preaches using your circuits as interval training instead of steady-state cardio. It's basically the difference between flying through all exercises without rest, and taking 15-45 seconds between exercises. I've been trying to figure out the cardio I'm going to be doing on my off days, and I think I'll adopt some of what he recommends to go along with my bike riding. I may have to go back and read his book again, the New Rules of Lifting. I'm still looking for a program that I can't live without...
