Are there any workouts for someone to get in shape if they have a curved spine?

Yes: Emphasize non-jarring sports, avoid both arms overhead or twisting with speed. Most people with spinal difficulties benefit from working with a physiatrist and physical therapist to learn a safe weight workout. Weight machines which provide a stable platform for arm and leg exercises can be helpful. Core strengthening routines are essential, whether done in water, pilates class or home mat.
