Well i saw this on TV like millions of others and i was compelled to buy it... Ive always been physically fit, played sports and have always worked out and done cardio, so i decided to give this a try. Needless to say this workout is absolutely nuts. Some of the workouts i could do right off the bat, like the chest and back, due to my fitness level. Than i tried the ploymetrics workout and i was completely humbeled, 20 minutes in and i basically had it. LOL. Well im on 30 days of this and im doing all the workouts fully through and im really getting back into amazing shape again. Only after 30 days, 60 days left, i cant even imagine. I was curious too see if anyone else has bought into the P90X hype like i have. Its an insane workout and you sweat like a stuck pig during it. For the real fitness freaks fast forward throguh the small breaks they give you and do the individual DVD's as one giant super set. Thats what ive been doing for chest and back. You'll be sore after every workout.
