Why Exercise Helps
It’s tempting to avoid moving altogether when your knees are stiff and achy, but that actually makes things worse. Joints love movement. It keeps them lubricated, strengthens the muscles around them, and helps prevent stiffness from taking over. Think of it like this: motion is lotion for your knees.
Now, don’t worry—I’m not about to tell you to start sprinting or jumping. We’re talking about gentle, low-impact exercises that help keep your knees strong and flexible without adding more stress. Let’s dive in.
1. Seated Leg Lifts

Perfect if standing for long periods isn’t your thing. Sit in a sturdy chair, straighten one leg, hold for a few seconds, then lower it back down. Switch legs and repeat. This strengthens your thigh muscles, which take some of the pressure off your knees. Bonus: You can do this while watching TV.
2. Heel and Calf Stretch

Tight calves can actually contribute to knee pain. Who knew? Stand facing a wall, step one foot back, and press your heel into the floor while keeping your back leg straight. Hold for about 20-30 seconds and switch sides. Simple, effective, and a great way to keep things flexible.
3. Hamstring Stretch (Without the Fancy Yoga Poses)

You don’t have to be a yogi to get a good stretch. Sit on the edge of a chair, extend one leg straight with your heel on the floor, and lean forward slightly. You should feel a nice stretch along the back of your thigh. Hold for a few seconds, then switch. Easy and super helpful.
4. Step-Ups (A Mini Workout That Pays Off Big Time)

Find a low step or sturdy platform. Step up with one foot, then bring the other foot up to meet it. Step down and repeat, alternating legs. This is a great way to strengthen your quads and improve balance—just be sure to hold onto something for support if needed.
5. Water Walking (Because Everything Feels Easier in Water)

If you have access to a pool, take advantage of it. Walking in water provides resistance without the impact of walking on hard surfaces. Plus, it feels great, especially on sore joints.
A Few Things to Keep in Mind
- Start Slow: Your knees need time to adjust. Don’t overdo it on day one.
- Listen to Your Body: A little discomfort is normal, but sharp pain? That’s a no-go.
- Stay Consistent: A few minutes a day adds up over time.
- Mix It Up: Doing a variety of exercises helps prevent boredom and keeps all the right muscles engaged.
The Bottom Line
Knee arthritis doesn’t have to mean giving up movement—it just means moving smarter. These exercises can help keep your knees happy, reduce pain, and improve mobility without pushing them too hard.
