Thats a good question! I dont know, I look at all these rotations that you have here and its like I cant do a single one of them because there are workouts that I dont have.
This is what I DO have:
STS
Shock cardio when it comes out
CTX
Imax 2 and Cardio + weights
Step blast
Step, Pump, Jump
Kick, punch, crunch
Im also considering getting 4D split because its on sale. I feel like I have a pretty good collection considering I have about 80 Firm DVDs too. I just finished STS a week ago, so now Im throwing a whole hodge podge of workouts (both Cathe and The Firm) together in no particular order. I just want some sort of structure now.
Thanks!
