Quickly replying while my dh packs the car for the drive home....
As long as you can pass P90X's fit test, you can do the rotation based on your goals. The fit test can be downloaded online. Weights are selected based on what you can lift for 6-8 reps (increasing strength) or 12-15 reps for definition. The Lower body workout is high reps/bodyweight or low weights. They show modifications for cardio, assisted pull/chin ups, and bands instead of weights.
My dh bought the X back in March 07. Surprisingly, I passed the fit test since I could barely do any of Cathe's advanced workouts!!! I decided to do a classic rotation with him.
During Phase 1, I lifted 12 to 15 reps. Then I decided to not waste my time and lift to increase strength. I'm so glad I did. I got much stronger. Cathe's advanced workouts are much easier!!! That's saying a lot coming from someone who couldn't even do the warm up in Basic Step Jan. 2007!
I didn't gain any weight. I may have lost a couple of pounds, but I ate a ton!!! My thighs and waist measured smaller. I can see the difference in how my body looks. My legs looked great! (But, my tush didn't look as great as it does from some of Cathe's lower body workouts.) I know my body fat% went down as my breasts are slightly smaller.
I'm taking a break from the X and using Cathe instead. I used Cathe's endurance and circuit workouts to prepare for the Roadtrip. Soon, I'll use Cathe's SL and GS series lifting as heavy as I can until her new series is released. I'll probably do another X round in November with my Xer checkin buddies. You're welcome to join us!
I was going to do BBC. I forget why I decided to pass on getting it. I think it was because I had a lot of Cathe dvds I wanted to do. Also, I'm not a huge fan of puke my guts out cardio. For some reason, I got that impression. I'm probably wrong about it.
Okay, dh is tap tapping his foot.
