Maxi backsie roller

This massage tool originated in the Orient, and is designed to 
be effective method to improve your awareness of your back, 
posture, and spine. It is fun and easy to use and invaluable to 
keep your back feeling toned and aligned.

Begin by lying 
still on a carpet or exercise mat, starting at the top of the 
spine in one place only (not meant to be rolled on). Each point 
needs 10 deep breaths. The erector muscles on either side of the 
spine can be reached at the same time, to facillitate stretching 
and elongating of the back. Relax, focus on one spot and 
breathe.
