If you haven't taken a class and would like to learn some of the benefits of foam rolling and how you can add it to your current program, read about it here.
On another, but similar, note: Yamuna Body Rolling is another amazing restorative technique that I highly recommend. The flagship studio is in NYC - but if you're not in the area you can also buy the dvds on their website. Take a class with Yamuna if you can! She's definitely an inspiration.
