lunge and twist

Injury Report: today I realized that I have tendonitis in my knee from the combination of twisting and lunging. I have been doing lunges for a few years with no problem but as soon as we added twists, my knee started to hurt. My greatest love was taiji (taichi), especially fighting. But I had to stop because of the chronic tendonitis in my knee. Virtually every taiji movement requires a lunge and twist.

Practice Report: worked out at the gym for 1 1/2 hrs.
