I am truly stunned by the negative comments as my experience has been so different!! Are we talking about the same place?? I have to admit I was pretty skeptical that Pilates would do much for me, but when my doctor recommended steroid shots for my herniated disk, I had to make the decision to help myself. At the advice of a friend, I signed up for a package of machine pilates at Body Vision. After 10 sessions, I felt virtually pain-free and I lived with back pain every minute of everyday. And, people told me I looked as if I lost 10 lbs. which was a total bonus!! All the instructors are very knowledgeable--from the yoga to the pilates to the kettlebell instructors. If you really want to see a change in your body (even at middle age), this is the regimen to try. I will be doing this for a long time, esp. if it keeps me out of the doctor's office.
