With the new STS coming out, I keep hearing to wait at least one day in between lifting weights. Is that just for heavy training, or does that apply to DVD's like the Hard Core and Intensity series? For example, if I do Pyramid Upper body Monday, then Pyramid Lower on Wed. could I still do a workout like Boot Camp or a Terminator workout in between on Tues., or is that too much weights. I really like to do workouts that have both cardio and weights, and alternate between those and only weights...is it counterproductive to do this every day? Any advice from some of you who are more experienced than me would be appreciated!
