Hi Repo,
I am presently doing the P90X series, but use Cathe's cardio workouts in place of the cardio in P90X. I am on week 4. That series incorporates mostly various pull-ups. They do show modification with bands. Since I can't do (and don't like) pull-ups, I use the bands. I don't feel the bands are effective, probably because I'm not using the right tension and/or not doing them correctly. Lawn mowers with free weights work well. I'll be done P90X in time for STS release. I hope when Cathe gets back from Dallas she will give us some information on the back segment of STS. If there are pull-ups in STS, I know Cathe will get us through them.
