我觉得以你的年龄与运动量，你的膝盖已经很好了

我右膝深弯时会疼，最近一年开始的，一开始觉得是spinning,后来觉得不一定和运动有关，因为天气不好时会疼

瑜伽我练多年了，没觉得对膝盖有任何影响。barre也在练，只要不深度屈膝，也没有使膝盖不适。spinning也还好

Golf I don't know, but tiger woods does have bad knee injury. All the twists should have an impact on knee

But again, my knee is ok with twist but hurts when deep bend, don't know about yours
