Very interesting!
I have used a medball to work in and around the hips on the advice of my therapist. Since then, I’ve brought in a softball and lacrosse ball to work the hips on occasion, but only when necessary.
He also got me doing a few new things that seem to keep my calves and achilles from getting too jacked, specifically low walks forward / side / backward.
How often do you foam roll? I’ve been doing it every time pre-workout since the start of the indoor season in October.
