I love my foam roller! If it wasn't for massaging my calves after my runs, I'd probably have to hang up my running shoes.
They're light weight, don't take up a lot of room and about $25 a pop. It may not be the same as an actual massage, but you can benefit from self massage and do it more frequently. Think of it as regular maintenance to your major overhauls if/when you get to an actual massage therapist. Enjoy!
