Hi, bzbnmom!
I've been mulling over your rotation, so I'm sorry it took so long to give you another response. You've put together a good rotation; I had a few ideas for tweaks that I hope you find helpful.
--I don't have a couple of the newer Firms you mentioned, so I'm not familiar with how much cardio they may actually contain. Since you do Cathe, and are new to the Firm, you may feel the need for more, or different cardio. I usually end up adding a day or 2 of non-Firm steady-state or interval-type cardio to any week of a Firm rotation.
--I second Casey's suggestion, for week 2. If you want to keep your original categories, switch Standing legs and Sculpted BHt, which (to me) is much easier. Plus, I like Upper Body and SL in the same week.
--Maybe switch Basics sculpting w/Tough Tape. Basics might serve as a good "intro" to Firming. But it would also be good for a day when you feel the need for something a bit lighter. I don't mean to imply that Tough Tape is a bad intro--Tracie Long uses great form and cues well.
--I like Fast Cheetah and Strong Bear in the same week; I did a rotation with just those 2 Fitprimes and some cardio and yoga last spring, and liked it.
--I'm not as familiar with the Fitprimes as with the Firms. I like them because they offer some very different movements and some interesting variations on familiar exercises. I didn't like them at all at first, but once I decided to keep an open mind, they're good workouts. So beware!
(btw, for me, these did not preview well at all! The busy set on the originals bothered me, but once I did them, I didn't notice it.)
--Casey makes a good point: 3 weeks of this has the potential to give you great results! But, (not meaning to be negative) it also has the potential for a bit of burnout--it's an ambitious regimen, even for an advanced exerciser, which I'm guessing you are. I would encourage you to pay attention to your body each day, and not hesitate to throw in a non-Firm or 2 when you feel the need.
Anyway, hope this helps. Thanks for sharing; you've encouraged me to put these together in a way I haven't tried before!
