A new thing I’ve started doing is foam rolling. Where as stretching lengthens the muscles, foam rolling also works on the deep tissue fibers. Basically imagine getting a deep tissue massage every day you want/need one without having to fork out for it.
It does look kind of odd at times and some moves make you look like your humping the damn thing. So to save myself some embarrassment I bought one for home instead. Well worth the £20 it cost me. I always end up feeling a lot better after 5-10 minutes on one, working out all the knots in my muscles.
