But I'm not going to throw away my Swiss ball, Veronica! It's just so nice and comfy to sit on and relax while meditating and doing breathing exercises. But that's all it's good for: It sure didn't get rid of my lower lumbar pain, no matter how many sets of core exercises I did with it. At least, I don't have any lumbar support pads in the racing seats of my little Beamer. I remember a PT telling me that sitting in those racing seats was "bad for my back". BS! Racing seats are ergonomically designed for comfort. I've driven back from Yosemite in them many times without so much as a twinge of lower back pain.
