I have something called Becker's muscular dystrophy. This basically means that I have very weak legs... or more precisely weak knees. It is pretty hard for me to walk upstairs, I can't really run and on a "bad knee day" my knees start to buckle. Before, when the sickness was in its early stages, it did not affect me as much, and so I used to study wushu. After my MD got worse, I stopped attending lessons. However, recently my interest in Chinese martial arts was renewed. Basically I wanted to find out your opinion on which Chinese martial art would be best suited for a person with such a condition. I personally was thinking of wing chun but maybe it isn't the best option for me.
