Knee pain is one of the most common problems people deal with every day. Whether it comes from sitting for long hours, old age, sports, or a past injury — the knee takes a lot of pressure throughout your life. The good news is that the right exercises for knee pain can make a big difference. They help reduce stiffness, build strength around the joint, and make daily movement easier and more comfortable.
At Mahi Hospitals, our team of orthopaedic specialists and physiotherapists work closely with patients to create personalised exercise plans. These plans are safe, practical, and built around each person’s condition. This guide covers everything you need to know — from warm-ups to targeted movements — to help you move better and feel better.
Why Exercise helps Knee Pain
Many people think resting is the best solution when their knee hurts. While rest is sometimes needed, staying still for too long can actually make things worse. The muscles around the knee become weak, the joint becomes stiff, and pain tends to increase over time.
Exercise works differently. When you move regularly in the right way, several good things happen:
- The muscles around the knee — especially the quadriceps and hamstrings — get stronger and take pressure off the joint itself.
- Blood flow improves, which helps the knee receive nutrients and heal naturally.
- The cartilage inside the knee stays healthy because movement helps it absorb fluid and stay nourished.
- Flexibility improves, which means less stiffness in the morning or after sitting for a while.
- Your overall body weight is better managed, which reduces the load placed on both knees with every step.
Research consistently shows that people who do regular, guided movement recover faster and have less pain than those who avoid activity. At Mahi Hospitals, physiotherapy exercise for knee pain is always part of a patient’s recovery plan — and most people notice improvement within a few weeks.
When to Avoid Certain Exercises
Exercising is helpful, but there are moments when you should slow down or stop completely. Pushing through the wrong kind of pain can lead to injury or make an existing problem worse.
Stop your exercise and speak with a doctor if you notice:
- Sharp or stabbing pain that gets worse while moving
- Sudden swelling in the knee during or after exercise
- A clicking or locking sensation in the joint
- Knee giving way or feeling unstable
- Significant increase in pain the day after exercising
If your knee is swollen or inflamed, it is better to rest until the swelling goes down. Gentle movements like ankle pumps or seated stretches may still be safe, but anything weight-bearing should wait. The team at Mahi Hospitals can guide you on exactly which movements are right for your stage of recovery.
Best Warm-Up before Knee Exercises
Warming up before any exercise is not optional — it is essential. A proper warm-up gets blood flowing to the muscles, loosens up the joint, and prepares the knee for the movements ahead. Skipping this step is one of the most common reasons people hurt themselves.
A simple warm-up routine for knee pain takes just 5 to 10 minutes and can include:
- Marching in place — Lift your knees gently while standing or sitting. Do this for 2 minutes to get your circulation going.
- Ankle circles — Rotate each ankle 10 times in each direction. This warms up the lower leg and improves flow towards the knee.
- Gentle knee bends — Stand and slowly bend your knees just a little — not a full squat — and straighten again. Repeat 10 times.
- Heel slides — Lie on your back, slowly slide one heel toward your body, then slide it back. Do 10 repetitions per leg.
After warming up, your muscles are ready. After you finish exercising, spend another 5 minutes cooling down with slow walks or gentle stretching.
Low-Impact Exercises for Knee Pain
Low-impact exercises are the foundation of any safe knee rehabilitation programme. They allow you to stay active and build strength without putting heavy stress on the joint.
Walking
- Walking is one of the simplest and most effective exercises for knee joint pain. It keeps the joint mobile, builds leg muscle, and improves overall cardiovascular health. You do not need equipment, a gym membership, or a lot of time.
- Start with flat, soft surfaces — grass or a track is better than concrete. Begin with 10 to 15 minutes a day and gradually increase as your comfort improves. Wear supportive shoes with a cushioned sole. Avoid hills or uneven ground in the early stages.
- Walking every day, even a short amount, is far better than occasional long sessions.
Stationary Cycling
- Cycling on a stationary bike is excellent for people with knee pain because it allows the knee to move through a controlled range of motion without bearing full body weight. It strengthens the quadriceps, hamstrings, and calves — all muscles that directly support the knee.
- Set the seat at a height where your leg is almost fully extended at the bottom of the pedal stroke. Keep the resistance low when starting. Aim for 15 to 20 minutes and increase gradually over weeks. Avoid leaning forward aggressively, as this can strain the knee in a bent position.
Swimming and Water Aerobics
- Water reduces the effect of gravity on your joints. When you exercise in a pool, your body feels much lighter, which means less pressure on the knee. This makes swimming and water aerobics one of the best exercises for knee pain, especially for older adults or people with severe pain.
- Simple water movements like walking in the pool, water kicks, and gentle aqua aerobics can significantly improve strength and mobility without discomfort.
Strengthening Exercises for Knee Support
The muscles around your knee are its best protection. Strong quadriceps, hamstrings, and glutes act like a natural brace — absorbing shock and stabilising the joint. These strengthening movements are a key part of physiotherapy exercise for knee pain.
Straight Leg Raises
- This exercise builds the quadriceps without bending the knee at all, making it very safe even in early recovery.
- How to do it: Lie on your back with one knee bent and the other leg straight. Tighten the thigh of the straight leg and slowly raise it to the height of the bent knee. Hold for 3 seconds, then lower slowly. Do 3 sets of 10 repetitions per leg.
Wall Sits
- Wall sits build strength in the thighs and glutes without any movement through the knee joint. They are particularly useful for people who want to improve endurance in the supporting muscles.
- How to do it: Stand with your back flat against a wall. Slide down slowly until your thighs are at a 45-degree angle (not a full squat). Hold this position for 20 to 30 seconds. Rest and repeat 3 times. Increase the hold time as you get stronger.
Step-Ups
- Step-ups simulate everyday movements like climbing stairs and help train balance along with strength.
- How to do it: Stand in front of a low step. Step up with one foot, bring the other foot up to meet it, then step back down with control. Do 10 repetitions per leg. Start with a very low step — even a thick book works — and only increase height when comfortable.
Hamstring Curls
- The hamstrings run along the back of the thigh and play a vital role in stabilising the knee. Weak hamstrings are one of the most common contributors to knee pain.
- How to do it: Stand behind a chair and hold it for balance. Slowly bend one knee, lifting your heel toward your buttocks. Hold for 3 seconds, then lower. Do 3 sets of 10 per leg. For added resistance, use a light ankle weight.
Calf Raises
- Though they target the lower leg, calf raises improve the stability of the entire leg, reducing strain on the knee during walking and standing.
- How to do it: Stand behind a chair, hold it lightly for balance, and slowly rise up onto your toes. Hold for 2 seconds, then lower slowly. Do 3 sets of 15. The slow lowering phase is just as important as rising — do not drop down quickly.
Stretching Exercises for Knee Flexibility
Tight muscles around the knee increase stress on the joint. Stretching keeps these muscles long and flexible, which reduces that tension and improves the range of motion.
Hamstring Stretch
- Tight hamstrings pull on the back of the knee and cause pain. This stretch relieves that tension.
- How to do it: Sit on the edge of a chair or lie on your back. Extend one leg straight and hold the back of the thigh. Gently flex the foot and hold for 20 to 30 seconds. Repeat 3 times per leg. Never force the stretch.
Quadriceps Stretch
- The quadriceps run along the front of the thigh and connect to the knee. Stretching them relieves pressure on the kneecap.
- How to do it: Stand next to a wall for support. Bend one knee and bring the heel toward the buttock. Hold the ankle gently. Keep the knees together and the back straight. Hold for 20 to 30 seconds. Repeat 3 times per side.
Calf Stretch
- Tight calves limit ankle movement, which in turn changes how the knee is loaded during walking. Keeping them flexible protects the knee indirectly.
- How to do it: Stand facing a wall. Place both hands flat against it. Step one foot back, keeping that heel flat on the floor. Lean gently into the wall until you feel a stretch in the back lower leg. Hold 20 to 30 seconds. Repeat 3 times per side.
IT Band Stretch
- The iliotibial band runs along the outer thigh and into the knee. When it is tight, it causes pain on the outer side of the knee — a very common complaint among walkers and runners.
- How to do it: Stand with one leg crossed behind the other. Lean sideways toward the back leg until you feel a stretch on the outer thigh. Hold 20 to 30 seconds. Repeat 3 times per side.
Exercises for Specific Knee Conditions
Different conditions require slightly different approaches. The best exercises for knee pain vary depending on what is actually causing the discomfort.
Exercises for Arthritis Knee Pain
- Arthritis causes inflammation and cartilage wear inside the knee. Exercises for arthritis should focus on gentle movement, not heavy resistance.
- Recommended: Water walking, seated leg extensions, gentle cycling, and range-of-motion exercises. Avoid anything that causes sharp pain or heavy impact. Warmth before exercise (like a warm towel on the joint) can help loosen the joint before movement.
Exercises for Runner’s Knee
- Runner’s knee (patellofemoral pain) is caused by the kneecap not tracking correctly. It responds well to quadriceps strengthening and hip abductor work.
- Recommended: Straight leg raises, clamshells (lying on your side and lifting the top knee like a shell opening), side-lying leg raises, and terminal knee extensions using a resistance band.
Exercises for Meniscus Pain
- The meniscus is the cushioning cartilage inside the knee. When it is irritated or torn, exercise must be gentle and avoid deep bending.
- Recommended: Straight leg raises, gentle heel slides, mini squats (bending only to 30 degrees), and gentle walking. Avoid lunges, deep squats, and twisting movements until cleared by your doctor.
Exercises after Knee Injury Recovery
- Post-injury rehabilitation focuses on gradually restoring full function. This follows a progression: range of motion first, then light strengthening, then functional movements.
- Recommended: Heel slides, quad sets (tightening the thigh muscle while the leg is flat), gradually increasing walking, step-ups, and balance training on a wobble board when stability returns.
- At Mahi Hospitals, our physiotherapy team designs structured recovery programmes after injuries and surgeries to ensure safe and complete healing.
Chair Exercises for Seniors with Knee Pain
For older adults with limited mobility, chair-based exercises are an excellent way to stay active and build strength without any risk of falling.
- Seated Leg Extensions Sit upright in a sturdy chair. Slowly extend one leg until it is straight, hold for 3 seconds, and lower it. Do 10 repetitions per leg. This works the quadriceps safely with no weight-bearing.
- Ankle Pumps Sit with both feet flat on the floor. Flex your foot upward, then point it downward. Repeat this pumping motion 15 times per foot. This simple exercise improves circulation and reduces stiffness — excellent for people who sit for long periods.
- Seated Marching Sit upright and alternately lift each knee as if you are marching in place. Keep the pace moderate and the movement controlled. Do this for 1 to 2 minutes. It activates the hip flexors and keeps the joint mobile without any impact.
Yoga and Mobility Exercises for Knee Pain
Yoga, when done carefully, can be highly beneficial for knee pain. It improves flexibility, builds body awareness, and reduces stress — which plays a role in how we experience pain.
- Child’s Pose Kneel on the floor and slowly sit back toward your heels as far as comfortable. Extend your arms forward and rest your forehead down. This gently stretches the hips, lower back, and knees. Hold for 30 seconds and breathe deeply. If kneeling is uncomfortable, fold a blanket under the knees.
- Bridge Pose Lie on your back with knees bent and feet flat. Slowly raise your hips off the floor until your body forms a straight line from shoulders to knees. Hold 5 seconds, then lower. This builds the glutes and hamstrings, which support the knee significantly.
- Gentle Knee Mobility Drills Sit in a chair or on the floor. Slowly bend and straighten the knee within a comfortable range. Do not force it — just move it gently through the range that feels okay. Repeat 10 to 15 times per side. This is especially useful in the morning when the joint is stiff.
Exercises to Avoid with Knee Pain
Just as important as knowing what to do — is knowing what to avoid.
- Deep Squats Deep squats place enormous pressure on the knee joint, especially the cartilage and the tendons around the kneecap. Unless specifically prescribed by a physiotherapist, avoid squatting below a 90-degree angle when you have knee pain.
- High-Impact Jumping Jumping — whether skipping, jumping jacks, or plyometric exercises — sends sharp, sudden force through the knee. This can worsen inflammation and damage already-stressed cartilage. Avoid until you are pain-free and your physio clears you for impact activities.
- Running on Hard Surfaces Running on concrete or hard tiles is jarring to the knee joint. If you want to run, choose soft surfaces like a running track or grass. Better yet, switch to walking or cycling until your knee is fully comfortable.
Tips for Exercising Safely with Knee Pain
- Proper Form and Posture Good form protects the knee. When doing any lower body exercise, keep your knee aligned over your second toe — never let it collapse inward. Engage your core for stability. If you are unsure about your form, ask a physiotherapist to check your technique.
- Using Ice and Rest After Exercise After exercising, if your knee feels warm or slightly sore, apply an ice pack wrapped in a cloth for 15 minutes. This reduces any post-exercise inflammation. Do not apply ice directly to skin. Allow at least one rest day between strengthening sessions so the muscles can recover.
- How Often to Exercise For most people with knee pain, exercising 4 to 5 times a week is ideal. Strengthening exercises should not be done every day without rest — muscles need recovery time. However, gentle mobility exercises and stretches can be done daily. Gradually increase duration and intensity over weeks, not days.
When to Consult a Physical Therapist
If your pain has lasted more than a few weeks, is getting worse, or is affecting your daily life, it is time to seek professional guidance. A qualified physiotherapist can assess your specific condition, identify the exact cause of your pain, and design a safe, personalised programme.At Mahi Hospitals, our orthopaedic and physiotherapy team provides expert, compassionate care for all types of knee conditions.
