If you live with arthritis, the idea of exercising can feel intimidating. The natural instinct is to rest painful joints, but countless studies show that movement is the essential “lotion” your joints need. Consistent, low-impact exercise can reduce pain, increase mobility, and strengthen the muscles that support your knees.
The key is choosing the right activities—ones that offer great benefit without the harmful pounding of high-impact motion. Here is your guide to the best exercises for arthritis without straining knees, built around the three main components of a safe workout for arthritis: aerobic activity, stretching, and strength training.
I. Low-Impact Aerobic Activities: “Motion is Lotion”
Aerobic exercise is crucial for managing weight, boosting mood, and delivering nutrients to your joints. The goal is to move your body and elevate your heart rate without joint-jarring impact.
| Exercise Type | Why It’s Arthritis Friendly | Key Tips for the Knees |
| Water Aerobics / Swimming | Water buoyancy supports your body weight, drastically reducing stress on the knees, hips, and spine. | Focus on gentle, continuous movement. Water walking is excellent. If swimming, avoid the vigorous flutter-kick if it causes strain. |
| Cycling (Stationary/Recumbent) | Cycling is a controlled, non-weight-bearing movement that lubricates the knee joint with minimal impact. | A stationary or recumbent bike (where you sit back) is ideal. Use light resistance and keep the seat high enough so your knee has only a slight bend at the bottom of the pedal stroke. |
| Walking | Simple, natural movement that improves circulation and function. | Choose smooth, flat surfaces and wear supportive, well-cushioned shoes. Break your walk into shorter 10-15 minute sessions if a full 30 minutes is too much. |
| Elliptical Trainer | Provides a fluid, gliding motion that mimics walking or running but keeps one foot on the pedal, reducing joint impact. | Use the handles to help support your balance and distribute weight. Start at a slow speed and low resistance. |
II. Flexibility and Stretching: The Power of Knee Arthritis Stretching
Range-of-motion (ROM) and stretching exercises are vital for fighting the stiffness caused by arthritis. They keep your joints moving through their full, available arc, which helps improve flexibility and reduce morning stiffness.
Gentle Stretches You Can Do Daily:
- Heel Slides (Lying Down):
- Lie on your back with both knees bent.
- Slowly slide one heel along the floor, moving it toward your buttocks, bending your knee as far as comfortable.
- Hold for a count of 5, then gently slide it back out. Repeat 10 times per leg.
- Quad Sets (Isometric):
- Sit or lie on the floor with your leg straight.
- Tighten the thigh muscle (quadricep) on top of your leg, pressing the back of your knee down toward the floor. You should see your kneecap move up.
- Hold the contraction for 5-10 seconds, then release. Repeat 10 times. This strengthens without moving the joint.
- Calf and Hamstring Stretches: Gently stretching the muscles that surround and support the knee can relieve tension that contributes to pain. Use a strap or towel to assist with hamstring stretches while seated or lying down.
- Mind-Body Practices (Yoga/Tai Chi): These practices are considered excellent arthritis friendly exercises. They combine gentle movement, deep breathing, and meditation to improve balance, reduce stress, and enhance joint mobility. Look for “gentle” or “restorative” classes.
III. Strength Training: Building a Foundation of Support
Strong muscles act as shock absorbers for your joints. By strengthening the muscles around the knee (quadriceps, hamstrings, and glutes), you can take stress off the joint itself.
Safe Strengthening Moves:
- Straight Leg Raises (Lying Down):
- Lie on your back with one knee bent and the foot flat on the floor. Keep the other leg straight.
- Tighten the thigh muscle of the straight leg and slowly lift the leg 6-12 inches off the floor.
- Hold for a few seconds, then slowly lower. Repeat 10 times per leg.
- Wall Slides / Mini-Squats:
- Stand with your back against a wall, feet shoulder-width apart.
- Slowly slide down the wall until your knees are only slightly bent (never below a 45-degree angle). Avoid going low if it causes pain.
- Hold for 5 seconds, then slowly slide back up. This is a controlled movement that works the quads without deep knee bending.
- Glute Bridges:
- Lie on your back with knees bent and feet hip-width apart.
- Squeeze your glutes (butt muscles) and lift your hips off the floor until your body forms a straight line from your shoulders to your knees.
- Hold for 3-5 seconds, then slowly lower. This is excellent for strengthening the muscles that support your hip and knee alignment.
Essential Exercise Guidelines for Arthritis
Before starting any new routine, consult with your doctor or physical therapist. They can help you design a personalized safe workout for arthritis.
- Start Slowly and Gradually: Begin with short sessions (5-10 minutes) and build up the duration and intensity over several weeks.
- Listen to Your Body: A little muscle fatigue is normal, but sharp, stabbing joint pain is a signal to stop. If a joint is hot, red, or swollen, skip exercise for that day and use ice/rest.
- Warm Up and Cool Down: Always start with 5-10 minutes of gentle movement (like a slow walk) and end with 5-10 minutes of gentle stretching.
- Prioritize Form: Good form prevents injury. If you’re unsure, ask a physical therapist to demonstrate the proper technique for key movements.
