I've done Strength I which rocked. It added Squat and DL strength.
Hyper I, which I liked, but kinda disagreed with the squats and DLs on the same day. It was a lot for the lower back to take, especially on the higher reps days. The upside is that I looked huge all the time while doing it. As Arnold would say I pretty much had a constant 'pump'
I'm back on Strength 2 now and it's good so far. Doing the heavy quarter squats and rack DLs really lets you 'feel' how much heavier the weight can get, and gets you used to it. I was doing quarter squats with 385 the other day and my mind is starting to think it's not so heavy anymore. Now if my body will catch up :p
