Thought I'd rekindle this thread to report. I started the 'Lean' version of P90X on Feb 1 and finished yesterday. I lost 18 pounds and feel incredible. I didn't do all of the measurements prior to starting other than stepping on the scale, but I've 'gained' 2 whole notches on my belt. I've been getting a lot of compliments. I decided to start with the lean version as it seemed slightly less intense. I wanted to shed some weight and I wanted to finish the program, not get burned out and quit halfway through. The eating part wasn't too difficult for me. I followed their guidelines fairly strictly at first, but it really wasn't that different than what my wife and I already try to do (she's a registered dietitian so that helps). But I did eat better throughout -- no soda, pizza only twice, drastically less chips and mindful of portion sizes. I drank less beer and only on weekends (or at Brewer games). The most difficult aspect for me was the time commitment. A lot of nights I wouldn't start working out until 9 or later which was tough, but I plowed through. I printed out a calendar just for this and x'ing off each day in blue sharpie was so fun. It's amazing to think back to when I started, and how I couldn't get through all of the workouts, whereas at the end I felt strong pretty much throughout. I'm able to get through everything on Ab Ripper which made me want to puke the first month. Saturday I helped my Grandma move and everyone else was dropping like flies, I was going strong all day and came home and did Yoga X. Now of course I have to keep the momentum going. I'm pretty active in the summer with biking, tennis, and jogging, but I'll definitely mix in a few of these workouts each week. Then I'd like to start the classic version of this in late summer or fall. And continue to eat smart. Just wanted to give some encouragement to anyone that might be doing it, or thinking about it. Thanks for letting me brag a little :-)
