In most of the weight workouts, you choose your own rep range and weights. Some of the workouts have women usiing lighter weights and doing 12-15 reps, while the guys do 8-10 reps for size. The workout I found most intimidating at first was "Chest and Back" because it is full of a variety of push-ups (I am...no, I take that back, WAS...a push-up weenie) and pull-ups (it was so intimidating for me on first viewing that P90X sat around unused for about 3 weeks! Then I jumped in, but with the SHoulders and Arms workout, which didn't scare me so much!).
The first time I did Chest and Back, I did most of the push-ups on my knees (using push-up bars) and substituted 1-arm rows and pullovers for the pull ups because I didn't have a pull up bar or heavy enough bands. It worked fine. The next time I did the workout, I could do more push-ups on my toes. By the third time, I was doing more on my toes, and I had gotten some bands and used those for pulldowns.
Tony's (the instructor's) whole philosophy is"Do your best, and forget the rest."
Most of the workouts are tough the first time (or second or third!) through, but they do get easier, and everything fits together so well.
