I have a recent set.
The books are almost impossible to copy as they are white letters on black glossy background.
I think it is a great program which is doable and with which, the one which will follow thru, will have results.
The system is pretty much 50% or more cardio and fitness oriented, but will make you grow too.
You will need an acceptable level of fitness to do it however and there are tests included before you start.
It is a no-BS approach and, to the contrary to many other "systems" offered on TV or the Internet, it includes a sensate base ideology: Change routine, workouts and chronology often. The body adapts incredibly fast to most any exercise and thus people tend to hit "ceilings" pretty fast. The idea goes back to the old recognition: Everything works, nothing works forever. You need to surprise your body to keep it busy.
P90X addresses all that with a good group of movements which are interchanged in progression and also speeds.
I recommend you BUY the system, instead of trying to obtain an illegal copy. You NEED the books. There is a nutrition plan which goes along the progress and also some written instruction as the system can be tailored to your needs. The DVD's alone will NOT help you reach your goals.
I also recommend you get the PerfectPullUp rig. It adapts better to Dominican doorways than P90X's chin up bar which is designed for US (drywall) standard width walls around doorways.
You can buy direct or off e-bay and have it shipped thru a Miami forwarder... it's only a couple of pounds.
