My knees give me more problems that anything else. The Rice Krispies (snap, crackle, pop) are always there but sometimes worse than others. My left, weaker, knee is often problematic. I know I must move my hip clockwise in an attempt to keep it under control. Sometimes successful. Sometimes not. The tubow forces me to concentrate on the problem.
I suspect that if all goes well by the end of March I will have surpassed or met my old pr levels. At least that's my goal.
