12 Essential Knee Exercises for Pain Relief and Stronger Joints
Build muscle support and flexibility to keep you active without discomfort.
Knee pain can impact everyday life, from walking and standing to working out and pursuing favorite activities. Whether you’re recovering from injury or aiming to prevent joint problems, strengthening and stretching your knees—and the muscles that support them, like the quadriceps, hamstrings, and glutes—can make daily movements easier while reducing discomfort. Below are the best expert-backed knee exercises, with form tips, modifications, and essential information for safer, stronger joints.
Why Exercising Your Knees Is Critical
The knee is the largest joint in the body and plays a vital role in supporting weight and enabling movement. Knee pain can stem from injury, overuse, or weakness in surrounding muscles. Regularly performing targeted knee exercises is an effective way to build joint stability, reduce risk of injury, and manage pain.
- Improved stability: Stronger knee-supporting muscles, such as the quadriceps and glutes, help absorb impact and protect the knee from stress.
- Better mobility: Increased knee flexibility and strength make daily tasks and workouts easier.
- Pain prevention and relief: Targeted exercises reduce pressure on the joint, minimizing aches during walking, cycling, or running.
Before You Begin: Safe Exercise Guidelines
- Warm up with gentle movement (such as walking) or dynamic stretching before starting strength exercises.
- Maintain proper form and avoid rapid movements that strain the joint.
- Modify exercises with props or alternative positions if needed.
- If you experience sharp pain (as opposed to mild discomfort), stop and consult a healthcare professional.
12 Top Exercises for Strong and Pain-Free Knees
1. Butt Kickers
Why it works: Butt kickers are a simple warm-up that boosts blood flow and gently mobilizes the knee joint before strength exercises. This helps loosen the joint and reduces injury risk. Ideal for activating muscles and prepping for more intense movements.
How to do it: Stand straight, optionally near a wall for balance. Alternate quickly bending each knee to bring your heel to your glute. Perform 20 repetitions per side for two rounds, with 30–45 seconds rest between sets.
2. Sit-to-Stand (Chair Squats)
Why it works: Standing up from a seated position engages the quadriceps, hamstrings, glutes, and even core stabilizers. This move mimics daily activities, making it highly functional and protective for the knees.
How to do it: Sit on a sturdy chair with feet flat on the ground. Cross your arms or hold out in front of you for balance. Stand up slowly, pressing through your heels and squeezing your glutes at the top. Lower yourself back down slowly. Perform three sets of 15 repetitions, using a higher seat if needed to reduce difficulty.
3. Glute Bridges
Why it works: Glute bridges target the glute muscles, which help take stress off the knees, reducing risk of incorrect knee movement (like caving in). Strong glutes support overall leg alignment.
How to do it: Lie on your back with knees bent and feet hip-width apart. Push your heels into the ground and lift your hips until your body forms a straight line from shoulders to knees. Squeeze your glutes at the top; lower down slowly. Complete three sets of 15 reps.
4. Hamstring Stretch
Why it works: Flexible hamstrings can relieve tension that impacts knee movement. This stretch also involves the core and hip flexors, improving lower body posture and stability.
How to do it: Lie on your back with one knee bent and the other leg straight. Lift the straight leg to a 90-degree angle, keeping toes pointed up. Lower slowly. Repeat three sets of 15 reps per leg.
5. Squats
Why it works: Squats are a cornerstone for building quadriceps strength—which is directly connected to knee stability. They also strengthen hamstrings, glutes, and hips.
How to do it: Stand with feet hip-width apart, spine straight. Lower your hips until knees form about a 90-degree angle (thighs parallel to the floor). Press through your heels to return to standing without letting knees move past toes. Use a chair for assistance if needed. Aim for three sets of 10–15 reps.
6. Leg Extensions
Why it works: Leg extensions strengthen the quadriceps while stretching the hamstrings. This dual action supports knee flexibility and resilience.
How to do it: Sit on a chair or bench with legs at 90 degrees. Straighten both legs until parallel to floor, then lower back down. Three sets of 15 reps are recommended. Add ankle weights for increased challenge if desired.
7. Monster Walk (Lateral Band Walks)
Why it works: This exercise strengthens the hip abductors and glutes, crucial for knee tracking and stability.
How to do it: Place a resistance band just above your knees. Stand with feet shoulder-width apart and toes forward. Take slow, controlled steps to the side (monster walk) for 10–15 steps, then return. Repeat for three rounds.
8. Deadlift (Romanian Deadlift)
Why it works: Deadlifts build strength in hamstrings, glutes, and the lower back, taking load off the knees during walking and running.
How to do it: Stand holding weights or household objects (like gallon water bottles), feet shoulder-width apart. Keep back straight; bend at hips to lower weights toward floor, slight bend in knees. Return to standing by driving hips forward. Three sets of 10–12 reps recommended.
9. Squat Sit Hold with Ball Squeeze
Why it works: Isometric holds enhance muscular endurance and knee joint stability. Inner thigh engagement provides extra support.
How to do it: Sit on a chair with a small ball or pillow between knees. Feet flat, arms extended forward. Shift weight and slightly lift hips, squeezing ball with inner thighs. Hold for 30 seconds, rest, and repeat three times.
10. Inner Rotation Leg Press
Why it works: This exercise works both the quadriceps and medial thigh, aligning knee tracking to reduce excessive stress.
How to do it: Use a resistance band or adjustable machine; press with feet angled inward to focus on the inner thighs. Three sets of 10–12 reps.
11. Bridge Ball Squeeze
Why it works: Combines glute bridge and inner thigh engagement, maximizing lower body activation and knee protection.
How to do it: Lie on your back, knees bent, feet flat, ball or pillow between knees. Lift hips to bridge, squeeze the ball at top, lower down. Three sets of 12–15 repetitions.
12. Hamstring Ball Rollout
Why it works: Targets hamstrings and calf muscles, improving knee movement and lower-body stability.
How to do it: Lie on your back, heels on exercise ball, legs straight. Lift hips and roll ball toward glutes by bending knees, then roll back out. Three sets of 10–12 reps.

Frequently Asked Questions (FAQs)
Q: What causes most knee pain?
A: Common causes include overuse, lack of strength in supporting muscles (quads, glutes, hamstrings), arthritis, injuries, and poor joint alignment.
Q: How often should I do knee exercises?
A: Most experts recommend 3 to 5 times a week, allowing for rest days in between sessions.
Q: Can I do these exercises if I have arthritis?
A: Yes, but start gently, avoid high-impact moves, and consult your doctor or physical therapist for customized advice.
Q: What should I do if I feel pain during an exercise?
