Looking for fitness pals loosing 100lbs P90x

Me and my wife just started p90X together and I'm trying to lose at least 60 pounds in the next 6 months. I'm doing it to feel better, sleep better and hope to look better than my friend at his own wedding! It will be hard to do, and I'm already soo sore. I hope we can stick to this thing. How long after p90x did you start training in Kung Fu? I am starting at almost 340 pounds here, which is a disgrace from my glory days at 215 and pretty chiseled. Its amazing what a sedentary job will do to you after getting out of the military and not in a good way. Good luck to us getting fit!
