I had to have back surgery a real long time ago and haven't had problems since....until now. When I had surgery, the doctor told me not to do high impact aerobics or lift more than 10 pounds. I LOVE to work out and have gradually increased my workouts to include high impact aerobics and I have definitely been lifting more than 10 pounds. (Perhaps this was a bad decision) I started to have a sharp pain in my back so I started doing what my doctor used to suggest. (All low impact and lifting only 10 pounds) The pain totally disappeared. Are there any workouts you recommend? I LOVE hard workouts, especially dance aerobics ones...I also REALLY enjoy step and I do not care for kickboxing. I have Low Max, High Step Challenge, IMAX 2, Cardio and Weights and Ab Hits. What should my next purchase be? I like to work out an hour a day.
