Could you tell me what's the best workouts for your back at home?

See below: There are many great exercises to strengthen the core. I would recommend a visit with a physical therapist or personal trainer to learn proper technique. One of the best exercises are called planks. To do this lay on your stomach and lift your belly and legs off the ground with your forarms and toes on the ground. Try holding this postion for 15-30 seconds at a time.

Back exercises: Recommend that you do gentle range of motion exercises daily. Also a good neutral spine core stability program to include front and side planks, birddog position, and pull-ins can be great exercise to strengthen the support of the spine. Videos of these exercise can be found in numerous web sites including youtube.
