Have you heard of the Chirp Wheel?
Do you carry your tension in your shoulders like I do? Then you need the Chirp!!
I've been having trouble with pain in my upper back and around my shoulder blades and wanted relief at home (instead of massage, the Chiro or PT). I got the back pain bundle (3 pack of Chirp wheels) and it has REALLY helped.
I tried a regular yoga wheel, but it about killed my back. The groove for your spine with the Chirp makes all the difference. Now that my pain and tightness are under control, I just roll on the wheel for a few minutes before bed. If I had to pick one, I would get the 12" gentle. The bundle is a great deal though!
