I recently hurt one of my knees doing something stupid and won't be able to do squats or lunges for a few weeks. My question is since i won't be lifting i decided to do a Firm Vol.1 floorwork for legs and am wondering if anyone has seen any kind of results from the firm floorwork. I also plan to walk alot the next 2 weeks for cardio since it doesn' seem to bother my knee. Just wondering about results. donam
