I am sorry to hear you are noticing some soreness and pain after the Cham fit workouts. Your suggestion of doing half of the workout one day and the other half the other is a great idea. Make sure you are getting in the mobility in the last 10min’s for each day though. You may be tight, causing extra pain in those joints. Do whatever you need to avoid injury! Staying healthy is always the top priority.
I hope that helps!
