I agree with Lorrie, start out with the CTX 6 day rotation, or make it 5 days if you're crunched for time. You can easily double up the weight training and do chest/back, bis/tris, and then shoulders so you hit them 2 times per week, like she said.
I worked out a really good 12 week rotation using the CTX series for the first 4 weeks, then switching to something totally different for 4 weeks, then switching again. You get great results when you keep your body confused.
For the second rotation, I'm going to do MIS twice per week and do cardio 4 times per week, using MIC and IntervalMax along with Cardio Kicks and Circuit Max. But you can use the cardio workouts you have. So, for an example, your second 4 week rotation, if you want to go that way, could be:
Mon- MIS
Tues- Interval Max
Wed- Step Fit or one of the Cardio Hits
Thursday- MIS
Friday- MIC
Sat- Bodymax
Then what I'm doing for a 3rd, 4-week rotation I'm going to switch to the PS series with cardio after. Switching the order of weights and cardio has given me great results in the past. So you could do:
Mon- Strong Legs and Abs
Tues- Chest/Shoulders/Tris plus Powermax after (all or 2 sections)
Wed- Back/Bis/Abs plus Stepfit
Thursday- Strong Legs and Abs
Fri- Ch/Sh/Tris plus half of MIC
Sat- Back/Bis/Abs plus Step Works
When you do the weight work first, by the time you get to the cardio you have already used so much fuel your body taps into stored fat for fuel much more quickly and you get more benefit in less time. So you can even do 2 of 3 step sections if you're too tired after weights for a whole step class and still get tremendous benefits.
So, hopefully that helps or at least gives you some ideas of how to play around with what you have. Variety of workouts and consistency of how often is the key to making changes. That and good nutrition to support your efforts.
You have a great selection of Cathe classes to choose from so you should see some great results. I have already and I just started my 12 week rotation!
Take care!
. Did you also post this up in the Ask Cathe area? She doesn't have tons of time to answer all rotation questions..but you could give it a shot. I hope you get tons of replys...like I said at VF..it helps us all;-).
