I have another approach to workouts- leave the crazy stuff to people whom have good insurance companies.. Sparkspeople as good middle of the road workouts for free..
Make exercise your friend, not so darn hard it becames a chore.. Also remember rest days, far too many people start up gangho and burn out before they have even started..
I personally experienced easier roads to get the same results. But thats humans in a nut shell gangho and hopes on looking like the instructor.. Remember folks half these instructors are born naturals..
