How much exercise is safe for someone with severe arthritis?
My father has advanced knee arthritis and his doctor said to stay active, but any movement seems to hurt him for days afterward. How much exercise is actually safe, and how do we find the right amount?
✓ Accepted answer
For someone with severe arthritis, the safest approach is low-impact exercise totaling about 150 minutes per week, divided into manageable sessions of 10 to 15 minutes several times a day rather than one long workout.
- Prioritize Gentle Motion: Focus on range-of-motion exercises and low-impact activities like swimming, water aerobics, or stationary cycling. The Arthritis Foundation emphasizes that movement reduces stiffness, and water-based exercises provide buoyancy that takes pressure off damaged joints.
- Use the "Talk Test": You should be able to hold a conversation while exercising. If you cannot talk, you are working too hard. Stopping when pain begins is crucial; aim for discomfort that fades after cooling down rather than sharp pain that lasts for days.
- Warm Up and Cool Down: Spend five to ten minutes warming up with gentle walking or light stretching to increase blood flow to the joints. Always follow with a cool-down to reduce inflammation and muscle tension.
- Consult a Physical Therapist: A referral from your doctor to a physical therapist can help you learn proper form. They can customize a routine that strengthens the muscles around the knee to provide better support without aggravating the cartilage.
- Listen to Your Body: If pain persists for more than 24 hours after a session, reduce the intensity or duration of the next workout. Flare-ups are common, so having a backup plan for low-activity days is normal and safe.
