I’ve broken my ankle before when I was younger couple times, I haven’t broken them since but here’s some interesting findings that ankle sprains can easily be avoided with regular ankle exercise that really consists of you balancing yourself on one foot.
A growing body of research suggests that many of those second (and often third and fourth) sprains could be avoided with an easy course of treatment. Stand on one leg. Try not to wobble. Hold for a minute. Repeat.
