I am having a VERY hard time letting go of continuing a rotation of the CTX series, but feel that I need to due to the interval nature of the workouts and the plyometrics--I know I can modify and I am doing that, but, it's time to try something else. So, I would like to ask: What kinds of rotations did you use early in your pregnancy? I know the goal is to maintain fitness now, but rotations help me stay committed to my workouts. I do have a treadmill, so walking is definitely an excellent option for me, but I'd still like to keep some Cathe tapes in my rotation. Any ideas/suggestions are greatly appreciated! Thanks
