I believe that this question has been asked before, but I am too lazy to do a search. I would like to know if anyone can tell me why or if it is okay to do a circuit workout the day after working a specific body part, or if you should wait 48 hours for that body part to rest. If you don't have to wait, can you please tell me why? Is it because the circuit workout is not focused specifically on that body part? I am working on the intensity series right now and I have Pyramid Upper the day before Boot Camp. I got the rotation from a thread Cathe posted, so I assume it is okay, but why? Thanks for any input. Have a great day.
