I haven't done the home workouts on CIZE but have been certified as a CIZE Live instructor. I'm almost 45 years old and new to insteucting so I'm in the gym a lot working on my queuing which makes me dance a lot. I haven't had that problem but I would listen to your body and don't ever be afraid to modify any moves that are difficult for you. As long as you're moving, you're burning calories.

I recently got Cize and it is great fun, I was really surprised that my arms were sore from the workout!
