Thanks for all the responses. I stopped doing plyo legs and went to squat rack legs and have been avoiding step cardio. That has helped a lot. I think plyo kicked me into a tailspin... I just need to alternate step with others and probably should avoid plyo altogether...
Are you feeling better, now? Is your knee still twingy at all? I'm thinking of getting some Classic Stretch DVDs along with that Total Body Solutions series.
Cathe - Can you give us old folks a DVD to use for our torn broken bodies?
