Exercise certainly seems to be a key for us all. I've seen the commercials for pilates and it looked good. Well, the taunt, super firm smiling people made it look good. Best wishes for continued success with it. I tend to stray off exercises after a few weeks. Another option is the 20 to 30 inch exercise ball. Roll around on one for a day or so and wow, lotta spinal crack'in! It seconds as a chair to boot.

Keep exercising and staying healthy!
