I have just finished a physical therapy program for my back. But my therapist wants me to keep doing exercises at home. How long do I have to keep this up?

Living with back pain can be a lifelong project. Once you've had a bout of back pain, you have a 90% chance that it will come back some day. Keeping your back strong and flexible and improving your overall fitness can help prevent recurring back pain. Exercise and staying active are also ways to help you decrease pain.
