I think burn 1 is the easiest of all the circuits.
I found the rotation as-is challenging the first time around because I never really lifted heavy. I used my weighted vest to increase the challenge so you may want to try that. After I completed 4 months of STS, I tried to go back to CLX and found it way too easy so I shelved the program.
I'm back to doing a CLX rotation, but I'm using it in a different way. I first started out doing the program as designed, and added insanity circuits in. That helped increase the challenge. Someone on the VF came up with this rotation and now I'm glad I didn't get rid CLX. I really like this rotation for fat loss. I'm doing 30-40 minutes of cardio after the CLX circuits.
This week, my full body workout is the 90 minute BM2. Next week, I'm going to do Cathe's Intensity series Bootcamp.
