Massage

Back Roller 

and Alternatives

Thanks! to "turbo" for recommending!

To buy, search the web for "massage back roller" or for "massage ma roller", or visit your local massage / physical therapy supply shop.

SOFTER ALTERNATIVES

CAUTION that you don't roll on something so hard that you injure yourself.  The wooden roller might be a too hard for some bodies; there are alternatives.  Tennis balls in a sock, for instance (old ones are softer, and preferable, imo).  Playground balls, of various sizes, are inexpensive and excellent for rolling under your back.  (Thanks! to Spectrum.)
