The workout itself is OK, but i love the conditioning of the second phase. I actually recommeneded that in a post from a few days ago about fatigued legs. Doing those 3 conditioning workouts on a bike or elliptical really did help me. Personally I did the 1st and 2nd phases and liked it but there are def. better workouts you can do but if you put in the time with this you will see results.
It looks incredibly intense, lots of hours in the gym. Reading ExRx.net, they prescribe no more than a couple sets per exercise. Interesting they link to studies that show that doing more than one set only gives up to 5% more gains.
I'd be interested to see what the conventional lifting theory would be in 20 years. Will it be higher rep, lower weight, higher sets...or will it be higher weight, fewer reps, fewer sets?
