Hey Debi,
I have scoliosis and osteoarthritis in my spine. My main reason for getting into fitness is my curved back. My doctor told me that if my muscles are strong, my bones are better supported, and weight-bearing exercises also help build bone. I used to be on three different prescription medications pre-exercise. Now, I'm off of them.
My PT told me I don't have to use heavy weights to get stronger, and for a while I believed him. But when I discovered Cathe I just had to see how far I could take myself. I'm starting my sixth month with my Cathe workouts and the weight I use just keeps increasing. I do pause my DVD's a lot to stretch my back after every set, especially when I'm doing leg work, where I put a heavy barbell on my back. Sometimes I worry about using so much weight because I fear that doing so might make my back worse. But so far, I only feel good. Better, stronger, energized. I don't remember the last time I took a muscle relaxant or pain killer because my back was ailing me. If anything, I take ibuprofen usually after doing chest work or those plie squats. I think that STRETCHING a lot even on days when I'm not working out has helped me greatly. That's why I tack on 10-15 minutes of very basic yoga after my Cathe workouts.
Just remember to keep proper form while working out and to listen closely to your body and let it rest. This has worked very well for me.
