If you have osteoarthritis, the ”wear and tear” form that can affect knees, shoulders and other joints, you’ve got company. An estimated 27 million people in the U.S. have it, and your chances of getting it increase with age.

One key to living well with osteoarthritis is being more active. While “Go, exercise!” may be the last thing you want to hear when you have OA, experts say that it really can help. Too little movement makes stiffness worse, while boosting movement improves joint function, strength and endurance. And as your muscles strengthen, your risk of falls—and fractures—declines, because your joints are better protected.

According to the CDC, physical activity can reduce pain and improve physical functioning in adults with arthritis by about 40 percent. But one in three adults with arthritis are inactive. Expert also say that you can actually reduce your arthritis symptoms by participating in a disease management education program. However, only one in 10 adults have participated in this type of program.

So, a little exercise and a little education can translate to better, less painful movement and functioning—but of course, you need a plan. If you’re motivated, check out our picks of the best mobile apps, websites and classes designed specifically for people with OA; most of these include exercises along with a disease management component.
