Hi there! I am so happy to see there are a few of you that are begining to use the bar in 2012! Mine should be arrving in a week. I too, have a back probelm,,a Spinal Fusion..I got tired of my Aero PIlates machine..it gave me a headache..seriously..the laying down jumping, made my neck and head hurt..I have 30 days of which to do this 3 times a week plus whatever else I can throw in the mix. Truth be told,I hate exercising.. Its boring and I' d rather be hiking..but since its winter and freezing cold, I decided on this. Lets bond together and kept eachother updated.
