I love to play tennis. I'm not too good at it but, who cares? I love to play and playing with my son gives me a serious run for my money. A handful of times I have considered myself very lucky not to have injured myself after a supinated (outside side of the foot) rollout. It seems to be the only time I do this with my feet. Hearing this similar issue with clients who do this on occasion while running or just about anything, I'd like to share how we can strengthen the muscles in their feet and ankles in order to avoid such injury. I've worked on it myself for several months and have yet to roll my feet out to the side since! In addition to the attached article, now that the warmer months are amongst us, how about putting on some rollerblades and going for a cruise? Don't be afraid to hold on to something along the way for confidence when you start. Laugh at yourself! Have fun with it and know that others who you think may be laughing at you are probably admiring your perseverance. Rollerblading is great for developing ankle stability as your lower half is working really hard to keep you balanced. You're also burnin' up all parts of your legs and glutes propelling yourself forward.
So often we only train the anterior and posterior parts of our bodies as exercises focused on those areas are most familiar to us. However, we have to keep in mind that the lateral and medial muscles that surround the front and back of our bodies must be conditioned as well to uphold our muscles. So load up the outer and inner sides of your legs with weights or nothing at all by using your own body weight. Same goes for our core. Our obliques which encompass those lovely love handles need to be awakened and strengthened as well to support what working in the front and back of our core.
