I've been having some back issues the past couple of years, including both sciatic problems and just general back pain. I've tried different things to help without much relief, so when I saw an ad online for the Plexus wheels, I thought I'd give them a try.
The first stretch was a bit uncomfortable, as I was putting the weight of my body on the wheel on my shoulders, but once I got a good full stretch, it was like night and day difference. The tightness and stress in my upper back was rolled away. I now do some stretches every day and my back just feels so much better overall!
