3. Strengthen key muscles.

People can live fairly pain free if they continue to move like they did when they were younger. Lack of exercise and movement leads to decreased flexibility, which leads back to less movement, creating a vicious cycle. The solution? Get more exercise.

By finding one or two simple exercises, says John McKenzie, a physical therapist with Heartland Rehabilitation Services in New Jersey, sufferers can build up the core muscles their bodies need to support their daily movements and increase their flexibility. If pain is severe or the result of injury, it's important to consult a doctor who will likely recommend working with a physical or occupational therapist to develop an exercise plan. Those intent on preventing pain can follow a self-directed exercise course, though an initial consultation with an experienced athletic trainer or physical therapist can insure that you're doing the exercises properly.

What you can do:

• Write down one simple goal -- like taking a walk several times a week -- and post it in a visible place, says Indiana University certified personal trainer Scott Catanzaro.

• Tell a friend or family member about your exercise goals, however small, and encourage that person to ask you about your progress regularly. This is especially helpful if you're not working with a physical or occupational therapist who provides built-in support.
