Thank you Trevor. I found a work out in a magazine that i like, it states a very similar theory and i wanted an opinion on it.
Its a weeks intensive workout which you follow on in less intensity. Starting with Day Ones Lower Body workout - Hamstring stretches, power lunges, crunches and similar 15/25 of each, whole work out repeated 3 times consequtively. Day Two Upper body, Weight works and similar, Day Three Peripheral Heart Action workout, then repeat upper body, then repeat lower body, etc...
I felt the muscles working, and it was intense, but it didnt feel painful afterwards. Is it intense enough for me?
