Knee injuries like runner’s knee and patellofemoral pain syndrome are common among runners due to the repetitive stress on the knee joint. This stress can lead to overuse injuries, ligament strain, and pain in the front of the knee. For runners, having strength in the quadriceps, hamstrings, glutes, and hip flexors is key to preventing knee pain and keeping their joints stable.
Strong muscles around the knee act as natural shock absorbers, reducing stress on the patella and supporting healthy movement. While many runners focus on cardio training, adding knee-strengthening exercises to their routine is key to avoiding injury and performance.
Devices like Motive can help strengthen the knee joint by targeting the quadriceps and gluteal muscles, so runners can build resilience and stay injury-free.
In this article, we will look at the exercises to prevent knee injuries and increase your body strength for a smooth run.
Common Knee Injuries in Runners
Here are the most common knee injuries runners face.
Patellofemoral Pain Syndrome (Runner’s Knee)

Patellofemoral pain syndrome (also known as runner’s knee) is when the kneecap (patella) rubs against the thigh bone due to muscle imbalances or poor movement patterns. It often causes pain in the front of the knee, especially when running downhill or after sitting for long periods. This injury is caused by weak quadriceps and hip muscles allowing the kneecap to move out of alignment.
Iliotibial Band Syndrome (ITB Syndrome)
Iliotibial band syndrome (ITB syndrome) is irritation of the iliotibial band, a thick band of tissue that runs along the outside of the leg from the hip to the knee. This condition is caused by overuse and can cause pain on the outside of the knee, especially after long runs. Tight hip flexors or glutes can contribute to this injury by putting extra stress on the IT band.
Meniscus Tears

The meniscus is a cushion-like cartilage in the knee joint that absorbs shock and stabilizes the leg. Tears in the meniscus can occur from sudden twisting movements or gradual wear and tear from running. Pain, swelling, and difficulty bending the knee are common symptoms.
Tendinitis
Tendinitis is when the tendons around the knee become inflamed, often from overuse or repetitive strain. The quadriceps tendon and patellar tendon are prone to this in runners. This can cause pain above or below the kneecap, especially during exercise.
Why Strong Knee Muscles are Important for Runners
Strong knee muscles are important for runners because they provide stability and shock absorption to protect the knee joint when you hit the ground. The repetitive pounding of running can put a lot of stress on the kneecap, ligaments, and surrounding tissues if the muscles around the knee are weak.
The key muscle groups, quadriceps, hamstrings, and glutes, are responsible for keeping the knee stable. The quadriceps, the main muscle group in the front of the thigh, controls the movement of the kneecap and makes sure it tracks properly.
The glutes and hamstrings at the back of the leg work together to absorb the shock of each footstrike and distribute the impact away from the knee joint. When these muscles are weak, the knee takes more of the impact and you’re more likely to get overuse injuries like iliotibial band syndrome or meniscus tears.
Finally, imbalances between muscle groups like tight hip flexors or weak glutes can cause poor movement patterns and put stress on the knee. Fixing these imbalances with targeted knee-strengthening exercises can prevent IT band syndrome and keep your knees strong and resilient.
Effective Knee Strengthening Exercises
Strengthening your quads, hamstrings, calves, hip flexors and core will give the knee joint the support it needs for stability and shock absorption. Here are the best knee exercises to know.
Quadriceps Exercises
Quads are the main stabilizers for the kneecap and are crucial for knee alignment. These exercises focus on strengthening the quads to reduce pressure on the knee joint and prevent injury.
-
Squats: Stand with your feet shoulder-width apart and lower your body down into a sitting position, keeping your knees behind your toes. Do 10-15 reps.
-
Lunges: Step forward with your right foot, bend both knees to a 90-degree angle, return to the starting position, and switch legs. Do 10 reps on each side, a single leg at a time.
-
Leg Extensions: Using a resistance band or bodyweight, sit with your legs bent, straighten, and slowly lift your right leg. Do 10-12 reps and then switch to the left leg.
Hamstring Exercises
The hamstrings help stabilize the knee joint and balance out the work with the quads to prevent imbalances.
-
Hamstring Curls: Lie face down with legs straight. Bend left knee to 90 degrees, then lower back down. Do 10-15 on each side.
-
Bridges: Lie on your back with your knees bent and flat feet. Lift your hips up towards the ceiling, and engage your hamstrings and glutes. Do 15 reps.
Calf Exercises
Strong calf muscles help reduce strain on the knee joint when running. One of the best exercises to strengthen these muscles is calf raises.
Stand with feet shoulder-width apart and slowly raise up onto toes, hold for a few seconds then lower back down. Do 15-20 reps.
Hip Flexor Exercises
Weak hip flexors can contribute to knee pain by overloading the knee during running. Strengthening these muscles can reduce knee stress.
Hip raises - Lie on your back with knees bent and feet flat on the floor. Raise one leg up into the air, and keep it straight, while lifting your hips. Do 10-12 reps on each leg.
Core Exercises
A strong core helps with balance and posture so your body stays stable and your lower back is protected during runs.
-
Planks: Hold a plank with your elbows on the ground and body in a straight line. Engage your core for 30-60 seconds.
-
Russian Twists: Sit with knees bent and feet flat, lean back slightly, and twist your torso from side to side with a dumbbell or resistance band. Do 20 reps.
Incorporating Knee Strengthening Exercises into Your Running Routine
To get the most out of knee strengthening exercises and prevent knee injuries you need to add them into your running routine strategically.
-
Frequency and Intensity Recommendations: Do these exercises 2-3 times a week. Start with lower intensity if you’re new to strength training and gradually increase the number of reps or resistance (add dumbbells or use a resistance band) as your muscles get stronger. Don’t overdo it, too much strain on the knee joint can lead to overuse injuries like runner’s knee.
-
Warm-up and Cool-down Exercises: Warm-up exercises like dynamic stretches, lunges, and leg swings will increase blood flow and flexibility around the knee. Post run do a cool-down with static stretches like hamstring and quad stretches to ease muscle tension and prevent stiffness.
-
Proper Form and Technique: Doing these exercises properly is key to not getting hurt. Make sure your knees, hips, and ankles are in line during movements like squats, lunges, and leg raises. For example, when squatting keep your knees behind your toes and your spine neutral. Improper form can put too much stress on your kneecap and ligaments and increase the risk of injury.
-
Listening to Your Body and Avoiding Pain: You need to listen to your body and stop if you feel any sharp or unusual knee pain during your exercises. Mild discomfort is normal when starting new strength exercises but consistent or severe pain is a sign of an underlying issue like patellofemoral pain syndrome or tendinitis. Consult with a physical therapist or running coach if you’re unsure of your form or if the pain persists.
The Role of Motive in Knee Strengthening
Motive is the solution for runners who want to strengthen the muscles around the knee joint and prevent injuries or pain. Using FDA-cleared technology, Motive is designed to increase muscle strength and overall knee stability which is critical for runners who suffer from runner’s knee, IT band syndrome, and tendinitis.
How Motive Strengthens the Muscles Around the Knee Joint

Additional Tips for Preventing Knee Injuries
Here are some additional tips that can make a big difference in preventing knee injuries while running.
-
Proper Running Form and Technique: Keep your body aligned by landing with your feet shoulder-width apart to reduce the impact on the kneecap, keep your knees slightly bent to absorb shock and prevent overuse injuries, and don’t overstride putting extra stress on the patella increasing the risk of runner’s knee.
-
Gradual Progression of Training Intensity and Mileage: A gradual increase in training volume gives your knee ligaments and thigh muscles time to adapt. The general rule of thumb is to increase your weekly mileage by no more than 10% to not put unnecessary stress on your IT band and quads.
-
Cross-Training to Reduce Stress on the Knees: Cross-training in your weekly routine can help reduce the repetitive stress on your knee joint. Low-impact activities like cycling, swimming, and yoga are great alternatives to running and strengthen the quads, hamstrings, and glutes. This helps to correct imbalances in your lower body and improve overall stability.
-
Adequate Rest and Recovery: Schedule rest days and consider adding cool-down stretches and strength exercises after your run to prevent injury. Leg raises, hamstring curls, and lunges during recovery can help keep your knee strong.
-
Appropriate Footwear and Running Surfaces: The right shoes can make a big difference to your knee health. Invest in running shoes that have sufficient cushioning, support, and stability for your foot type. Replace them every 300-500 miles so they continue to provide adequate protection. Running on softer surfaces like grass or a track can reduce the impact on your knees compared to concrete or asphalt.
