I think you'll find the p90x a challenge, even if you go the gym. After two weeks of it I felt better. I couldn't keep up with working out 1-1.5 hr a night for 6 nights a week. I felt like I was getting home from work, p90x, shower, eat, sleep. Repeat. It was hard to keep up with that, and I couldnt find the time to walk the dogs etc. So, if you have the time, and can do it, I think it is a great workout.
