I did px90 before I got preggo. I lost 30lbs but I was on a raw foods diet and hitting the gym too. I kinda went fanatic with it. I burned some of the DVDs for my dad. He doesn't do the program just the stretches and yogo. He has his own gym at the pad. He's 53 with a six pack. I haven't seen insanity I'm gonna ckeck it out and see if there's a torrent. You need a pull up bar in your doorway and some weights for px90. I need to go hard asap, can't hardly fit any of my jeans and my twins are one now, no more excuses!
