“As with many forms of arthritis, ‘motion is lotion,’ meaning that some form of physical activity and exercise is beneficial,” says Makol. People with arthritis who exercise regularly have better daily functioning, more energy, and less pain, according to the American College of Rheumatology.A sedentary lifestyle can harm your health in many ways, from increasing your risk for heart disease to further damaging your joints. “A lack of muscle strength can mean a lack of joint protection,” Deane says. “Exercise and physical activity also seem to have some anti-inflammatory effects that may have benefits for people with RA.”You don’t need to run a marathon to reap the benefits of exercise. “Low-impact aerobic exercises incorporating some strength training, joint protection principles, and stretching for flexibility are most optimal for people with RA,” says Makol. Talk to your doctor or physical therapist about creating a personalized exercise plan that works for you.
