i hurt my ankle pretty badly running a 10k a little over a month tho......i freaked out thinking i couldnt do cardio for a while or train my legs............but i still was able to extentions and curls.......hurt too much to train calves tho for a couple weeks..........
as for cardio, you still should be able to use the stairmaster.......it shouldnt really affect your ankle........try a low intesity.......
Strength does not come from winning. Your struggles develop your strengths. When you go through hardships and decide not to surrender, THAT IS STRENGTH
