Many people with rheumatoid arthritis avoid exercise, fearing it will worsen their joint pain. But regular physical activity is one of the most effective ways to lessen the pain, stiffness and disability often associated with rheumatoid arthritis.

If you have rheumatoid arthritis, regular exercise can boost strength and flexibility. Stronger muscles can better support your joints, while improved flexibility can aid joint function.

Exercise can lessen fatigue and ease depression. And better overall fitness helps reduce the risk of heart disease and diabetes, two serious conditions that are common in people with rheumatoid arthritis.

Rheumatoid arthritis speeds up the loss of muscle mass that typically occurs as people get older. That's why it's important to do exercises that can build muscle along with aerobic exercises that can strengthen the heart and lungs.

Weight-bearing exercises such as walking can help prevent osteoporosis. Osteoporosis is a condition in which bones become weak, brittle and more prone to fractures due to loss of bone density and strength. People with rheumatoid arthritis are at higher risk of osteoporosis.

Studies show that exercise does not worsen rheumatoid arthritis symptoms. But if the condition has severely damaged your hips or knees, you may want to choose low-impact exercises, such as swimming, water aerobics, walking or bicycling.
