Up for sale is a Nubax back stretch device. I was using this daily until my shoulder, which had been separated in a motorcycle accident, started giving me problems. It works pretty well and gives a good stretch. It's fairly portable and doesn't take up much space. These got for over $225 on line at several vendors. I'm starting at $100. Instructions and videos on how to use it are available on line. If interested, please respond to this posting and I'll get you contact information. I'm near 120th and Sheridan. Cash and local only please. Thanks for looking.
