Hi Lulu,
I followed the rotation the Cathe created when these workouts were released. We did them three times a week, alternating. So one week you would do TTM twice and CF once, and the next week you would do CF twice and TTM once, alternating with weight work. That was a tough rotation. You can find it here,
http://cathe.com/forum/f100/july-2012-rotation-289653/. If you stick with this program for the entire month, there's no way you're not going to get results, whether you lose a few pounds, and/or increase your fitness level dramatically. If you don't have all the workouts, don't let that discourage you, just substitute something similar. I don't have IMAX 2, so I used IMAX 3. I also subbed some of the weight workouts as I don't have the Gym Style Workouts. I used STS Meso2 workouts for those, because that's what I had. I did buy Muscle Max, but I had wanted it anyways because I used it as an excuse to buy another full body weight workout that I had not already done a million times (High Reps).
If you decide to try this rotation, come back and share your results with us. We always like to hear about results!! That's what it's all about.
