When you injured your knee how much time did you take off from lifting and cardio? Did you modify any at all or did you stay away from exercise completely? I injured my knee a couple weeks ago and have still been doing you step videos and light lower body work but my knee never seems to get better. I know that I probably just need to do nothing for the next few weeks but that would be sooo hard, considering I have 5 new DVD waiting for me to try:9 Thanks so much Cathe, you are my inspiration.
