Your knees are the hinge joints that connect your upper and lower legs. They help you to bend, straighten and twist your legs. The parts of the knee include:
- Bones — There are three bones that meet at your knee:
- Femur — Thighbone
- Tibia — Shinbone
- Patella —Kneecap
- Cartilage — Cartilage is a smooth, rubbery tissue that covers the ends of the bones. It helps reduce friction and protect the bones.
- Ligaments — Ligaments are tough bands of tissue that connect the bones. They help to stabilize the knee and prevent it from moving too far in any direction.
- Tendons — Tendons are strong bands of tissue that connect muscles to bones. They help the knee move.
When you bend your knee, the femur slides over the tibia. The patella moves up and down in a groove on the femur. Muscles in your thigh and leg help to move your knee. You use your knees for many activities, including walking, running, jumping and even sitting.
It’s essential to take care of your knees to prevent injuries and keep them healthy. One step you can take to accomplish this is to do knee strengthening exercises.
Why knee strengthening exercises may be recommended
When you have knee pain or weakness, your doctor or physical therapist may recommend knee strengthening exercises. These exercises can help you to:
- Reduce pain — Stronger muscles can better support your knee and reduce pain.
- Improve stability — Strengthening the muscles around your knee can help improve its stability and prevent injuries.
- Increase range of motion — Knee strengthening exercises can help you improve your knee’s range of motion, making it easier to bend and straighten your leg.
- Improve function — Stronger knees can help you to perform daily activities more easily, such as:
- Walking
- Running
- Climbing stairs
If you have knee pain or weakness, it’s important to see a health care professional to help determine the underlying cause and to get personalized recommendations for treatment, such as physical therapy. Knee strengthening exercises, when done correctly under the guidance of a health care professional, can be a valuable part of your recovery or maintaining your knee health.
How often should you do knee strengthening exercises?
The frequency of your knee strengthening exercises will depend on your specific situation and goals. However, a general guideline is to aim for two to three days of exercises per week. This allows your muscles to have time to recover between workouts. When doing knee strengthening exercises, it’s essential to remember to:
- Listen to your body — If you experience pain, stop the exercise and rest.
- Consult a health care professional — Your doctor or physical therapist can provide personalized guidance based on your condition.
- Start slowly — Gradually increase the intensity and duration of your exercises.
Consistency is key to building and maintaining knee strength. By sticking to a regular exercise routine, you can gradually improve your knee strength and reduce pain.
Knee exercises that can help strengthen your knees
When it comes to strengthening your knees, it’s important to focus on exercises that target the muscles surrounding your knee joint. These muscles provide stability and support, helping to reduce pain and improve overall function.
Here are some strengthening exercises your physical therapist may have you perform during sessions to improve stability and support around the knee:
- Straight-leg raises — Lie on your back with one leg straight and the other bent. Slowly raise your straight leg a few inches off the floor. Hold this position for a few moments and then slowly lower. Repeat with your other leg. This exercise targets your quadriceps muscles in the front of your thigh.
- Wall squats — Stand with your back against a wall with your feet shoulder width apart. Slowly slide down the wall as if you were going to sit on a chair. Keep your back straight and core engaged. Hold the position for a few moments and then slowly push back up. This exercise helps work your quadriceps, hamstrings and glutes.
- Heel slides — Sit on a chair with your feet flat on the floor. Slowly slide your heels away from the chair as far as comfortable, keeping your toes on the floor. Hold for a few moments; then slide your feet back to starting position. This exercise targets your hamstrings.
- Calf raises — Stand with your feet shoulder width apart and hold on to a sturdy object for balance. Rise up onto your toes, hold for a few moments and then slowly lower back down. This exercise helps strengthen your calf muscles.
- Side leg lifts — Lie on your side with your legs stacked on top of each other. Slowly lift the top leg a few inches off the floor, hold for a few moments and then slowly lower back down. Repeat on the other side. This exercise targets the hip abductor muscles.
- Hamstring curls — Lie on your stomach with your knees bent. Lift one heel toward your buttocks, squeezing your hamstrings. Hold for a few moments and slowly lower back down. Repeat with the other leg.
- Mini squats — Standing with your feet shoulder width apart, lower your body as if you were going to sit on a chair. Go down as far as comfortable, keeping your back straight, and then return to starting position. This exercise works the quadriceps, hamstrings and glutes.
- Leg circles — Lie on your back with one leg extended and the other bent. Make small circles with the extended leg, gradually increasing the size of the circles. Repeat with the other leg. This exercise helps improve your legs’ range of motion.
- Resistance band exercises — Use a resistance band to add extra challenge to exercises like hamstring curls and side leg lifts. This can help increase your strength and stability.
- Clamshells — Lie on your side with your knees bent and stacked on top of each other, and open your knees like a clamshell. Keep your feet together while you open your knees. This exercise helps target the hip abductors.
- Single-leg balance — Stand on one leg and try to maintain your balance for as long as possible; then switch legs and repeat. This exercise helps improve your stability and coordination.
- Step-ups — Step up onto a small platform or step with one leg; then step down with the same leg. Repeat with the other leg. This exercise helps work your quadriceps and glutes.
- Bicycle crunches — Lie on your back with your knees bent and your hands behind your head. Bring your right elbow forward and try to touch your left knee. Switch sides. This exercise targets your core muscles, which help support your spine and pelvis.
By following the directions of your doctor or physical therapist, you can effectively strengthen your knees and improve your overall well-being.

Knee strengthening exercises can be beneficial for individuals with various conditions that affect the knee joint, including:
- Osteoarthritis
- Rheumatoid arthritis
- Knee sprains

How knee strengthening exercises help the knees:
- Muscle support — Stronger muscles provide better support for the knee joint, reducing stress on the bones and cartilage.
