its very interesting, but for the last section on the dual factor training, does anybody have an example of a program already written up?? i'm more visual, and also i was reading and they were saying that if you reach into the regions of 10-15, more build up of lactic acid and fatigue, so my question is, if your doing 15 reps, should you switch and have a heavier weight and do lets say 10 reps??
Thx
