OK, I don't think you caught the reason I asked about 4 days. I am on stronglifts 5x5, beginners. Means I do squats every workout, 3 times a week. WB tells not to do cardio on leg days, and you say the same thing, but see I have 3 leg days. That's why I'm at a bind here, it's not that I am trying to change what's prescribed, I am trying to integrate it.
