How to Use THe SMR Map:

Just click on an area of the body to learn about it’s function and how to release it on your own! Before you get started, you’re going to need some basic equipment. All you need is a foam roller and a tennis ball. If that doesn’t feel like it’s massaging deep enough, you’ll need a 6″ PVC pipe and a lacrosse ball.
