I had a multi-level spinal fusion in November 2010, then a revision to extend the fusion in November 2011. I am looking for something to do so that I don't feel so stiff. I do walk every day, but am looking for something else. My mom does Bikram yoga every day and I am considering going with her. She said I would talk to the instructor before class so that they know my limitations (I'm not suppose to bend at the waist, but was wondering if anyone has done this after surgery.
