Arthritis in the knees can cause pain, stiffness, and reduced mobility. However, engaging in regular, appropriate exercise can help alleviate symptoms, improve joint function, and enhance overall quality of life. Here are specific exercises you can do to manage arthritis in your knees.

Types of Exercises for Knee Arthritis
Low-Impact Aerobic Exercises
Low-impact aerobic exercises increase heart rate without putting excessive stress on the knees. These exercises help maintain cardiovascular health, improve joint function, and aid in weight management.
Walking
Walking is a simple, effective way to keep moving without straining the knees. Aim for 30 minutes of walking most days of the week. Use supportive shoes and opt for flat, even surfaces.
Swimming and Water Aerobics
Exercising in water reduces the impact on your joints while providing resistance that strengthens muscles. Swimming, water walking, and water aerobics are excellent choices.
Cycling
Cycling, whether on a stationary bike or outdoors, is a low-impact activity that strengthens the quadriceps and hamstrings, improving knee stability. Adjust the seat height to ensure a comfortable ride.
Strengthening Exercises
Strengthening exercises target muscles around the knee, providing better support and reducing stress on the joint.
Quadriceps Strengthening
Straight Leg Raises:
Lie on your back with one leg bent and the other straight.
Lift the straight leg to the height of the bent knee.
Hold for a few seconds, then lower it slowly.
Repeat 10-15 times for each leg.
Wall Squats:
Stand with your back against a wall, feet shoulder-width apart.
Slowly slide down into a squat position, keeping your knees over your ankles.
Hold for 5-10 seconds, then slide back up.
Repeat 10 times.
Hamstring Strengthening
Hamstring Curls:
Stand behind a chair, holding onto the backrest for support.
Slowly lift one foot towards your buttocks, keeping your knees together.
Hold for a few seconds, then lower your foot.
Repeat 10-15 times for each leg.

Consult a Professional
Work with a physical therapist or fitness professional to develop a safe and effective exercise plan tailored to your needs.
