Knee Arthritis: Exercises to Avoid for Less Pain and Stronger Joints

Knee Arthritis: Exercises to Avoid for Less Pain and Stronger Joints

August 11, 2025

Knee arthritis can make everyday tasks feel hard. Climbing stairs, getting up from a chair, or walking around can lead to pain and stiffness. At Simply Physio, we help people manage knee arthritis so they can stay active and enjoy life.

Exercise is key to managing knee arthritis, but not all exercises are safe for arthritic knees. Some moves can make pain worse or cause swelling. Knowing which knee arthritis exercises to avoid can help you stay safe while keeping your knees strong.


Understanding Knee Arthritis

Knee arthritis happens when the cartilage in your knee wears down. This makes the bones in your knee rub together, which can cause pain, swelling, and stiffness. The most common type is osteoarthritis, which usually happens as we age.

Good movement and exercise can help manage arthritis. It keeps the joint moving, strengthens the muscles around the knee, and helps you stay independent. However, certain exercises can stress your knees and lead to more pain.


Why Exercise Matters for Knee Arthritis

Even if your knees hurt, avoiding all movement is not the answer. Staying active can help you:

  • Reduce stiffness
  • Improve your strength
  • Support your knees during daily tasks
  • Reduce pain over time

But it is important to choose the right exercises to avoid making your pain worse.


Exercises to Avoid with Knee Arthritis

While exercise is helpful, these are exercises you should avoid if you have knee arthritis. These moves can put too much stress on your knees, leading to pain and swelling.

Deep Squats
Squatting too low can put high pressure on your knee joints. This can increase pain and risk of injury, especially if your knee muscles are weak.

Lunges
Lunges place high stress on the front of your knees, especially if your form is off. They can increase pain and discomfort.

High-Impact Exercises
Running, jumping, and high-impact aerobics can increase stress on your knees. These activities can lead to more pain and swelling.

Stair Running
Running stairs is hard on your knees due to the high force with each step. This can lead to flare-ups in knee arthritis.

Leg Extensions with Heavy Weights
Using heavy weights on the leg extension machine can increase pressure in your knee joint, leading to pain.

Full Arc Knee Extensions
Extending your knees fully with heavy resistance can stress the joint, leading to discomfort.

If you are unsure whether an exercise is safe, speak to your physiotherapist before trying it.


Why Avoid These Exercises?

These exercises can:

  • Increase the pressure inside your knee joint
  • Lead to swelling and pain
  • Cause inflammation
  • Delay your progress in managing arthritis

Protecting your knees while staying active is key to managing arthritis.


What Happens if You Do These Exercises?

Doing these exercises may lead to:

  • Sharp or dull pain during or after activity
  • Swelling in your knee joint
  • Stiffness the next day
  • More pain that limits your daily activities

If you notice these signs, it may mean you are doing exercises that are too hard for your knees.


Signs an Exercise Is Too Hard for Your Knees

It is important to listen to your body when you exercise. Stop the exercise and seek advice if you notice:

  • Pain during the exercise that does not go away after stopping
  • Swelling in your knee after activity
  • A feeling of instability in your knee
  • Pain that lasts longer than two hours after exercise

Your physiotherapist can help guide you to safe exercises that will help, not hurt, your knees.


Safe Exercise Alternatives

While there are exercises you should avoid, there are many safe exercises you can do to help strengthen your knees and reduce pain. At Simply Physio, we guide clients to build safe, effective programs.

Here are safe alternatives you can try:

Straight Leg Raises
This helps strengthen your thigh without putting weight on your knee.

Mini Squats
Squatting only halfway can strengthen your legs with less knee stress.

Seated Knee Extensions (No Weight)
Gently extend your knee while seated to improve range of motion.

Swimming or Water Aerobics
Water reduces joint stress while letting you move safely.

Cycling on a Stationary Bike
This helps improve knee mobility with low impact.

Always check with your physiotherapist before starting new exercises to ensure they are safe for your condition.


Importance of Strength and Mobility

Strengthening the muscles around your knee helps protect your joint. Strong muscles take pressure off your knees, making it easier to move without pain. Mobility exercises keep your knee moving well, reducing stiffness.

Combining safe strength and mobility exercises can help you:

  • Walk and move with less pain
  • Improve balance
  • Maintain independence
  • Reduce arthritis progression

Building a Safe Routine

A safe exercise plan for knee arthritis should include:

  • Warm-up with gentle movements
  • Strengthening exercises for your thighs and hips
  • Low-impact cardio activities
  • Flexibility exercises for your legs
  • Cool down with light stretching

Avoid pushing through pain. If something hurts, stop and adjust. Your physiotherapist can help you create a plan that fits your needs.
