During high school I got really good at Dance Dance Revolution (i.e: a video game where you rhythmically stomp on four squares). Now 10 years later, I am trying to make a comeback.
When I play, I pivot in place, and the friction between my shoes and the dancepad causes torsional stresses on my knees. This strain on my knees quickly becomes a problem.
I'm not sure how one's knee fights such a stress. What can I do to strengthen my knees against torsional stress?
