The knee joint is the largest joint in the body, connecting the thigh to the lower leg. The knee joint consists of the end of the femur bone connecting with the tibia and fibula. The two main actions of the knee are flexion and extension. Flexors, or muscles that pull the knee in, include the articularis genus, rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis. Extensors, or muscles that extend the knee out, include the biceps femoris, semitendinosus, semimembranosus, and gastrocnemius. Hip flexor muscles are also important for lifting the knee when running, and weak hip flexors can impact running speed and increase the risk of injury. Tightness in the glutes and hamstrings can also restrict the range of motion in the hips and impact the ability to lift the knee.

Hip flexor muscles: strengthen hip flexors to lift your knee when running
The hip flexors are a group of muscles responsible for flexing the hip, or bringing the leg upward toward the body. The primary hip flexors are the psoas major and the iliacus, which, collectively, are often called the iliopsoas. The psoas originates from the lower six vertebrae of your spine, while the iliacus originates from the inside bowl of your pelvis. They meet and insert at the top of the femur, or upper leg bone. The iliopsoas works to stabilize the trunk during activities such as lifting, pushing, and pulling. The iliopsoas also draws the knees toward the chest, which is important when running or performing kicking movements in sports.
If your hip flexor muscles are weak, they won't be able to lift your knee and leg up in front of you as you run. The upward knee movement is important for producing a more powerful leg drive that can propel you forward when running. According to certified strength and conditioning specialist Kevin O'Neill, the stronger your hip flexors, the faster you'll be able to run. Additionally, because the hip flexors act as breaks to the hamstrings, they help reduce the risk of injury.
To improve the strength of your hip flexors, incorporate strengthening exercises into your regimen two to three days per week. Here are some exercises to target the hip flexors:
- Hanging knee raises: Lie on your back with one knee bent. Extend the opposite leg, keeping the knee straight. Tighten your abdominals as you lift the leg up so the thigh is in line with the opposite bent knee. Hold for a count of 2, then slowly lower to the starting position. Repeat with the other leg.
- Straight-leg situps: Lie on your back with your legs straight. Bring one knee toward your chest. Grip your thigh to pull it into your chest to feel the stretch. After you're finished, switch legs.
- Lunges: From a standing position, look straight ahead and take a generous step forward with your right foot.
- Lying leg raises: Lie on your back with your arms at your sides, knees bent, and feet on the floor, hip-distance apart. Try to position your feet so your fingers can touch your heels. While squeezing your glutes, press into your heels and lift your hips off the floor toward the ceiling.
In addition to these targeted exercises, it is important to include dynamic stretches before your runs and static stretches after your runs to improve flexibility and mobility in the hip flexors. High knee jogs, walking straight-leg kicks, and high-knee skips will warm up the hip flexors while simultaneously stretching the glutes and hamstrings. Static stretches such as the lying knee-to-chest stretch and the hamstring stretch can be held for 30 seconds to effectively target the glutes and hamstrings.

Leg raises: strengthen hip flexors with exercises like straight-leg situps
The knee joint is the body's largest joint, connecting the thigh to the lower leg. The knee supports the body's weight and enables leg movement. The hip flexors are a group of muscles responsible for flexing the hip, or bringing the leg upward toward the body. The primary hip flexors are the psoas major and the iliacus, which, collectively, are often called the iliopsoas. The psoas originates from the lower six vertebrae of the spine, while the iliacus originates from the inside bowl of the pelvis.
If the hip flexor muscles are weak, they will be unable to lift the knee and leg up in front of you while running. The upward knee movement is important for producing a more powerful leg drive that can propel you forward when running. To improve hip flexor strength, incorporate strengthening exercises into your regimen two to three days per week.
Straight-leg sit-ups are an effective way to strengthen the hip flexors. To perform this exercise, lie on your back with one leg resting straight on the floor and the other bent at the knee, with your foot flat on the ground. Raise your straight leg toward the ceiling, focusing on keeping your leg straight. This exercise targets key muscles that support walking, stair climbing, balance, and core stability.
Other exercises that strengthen the hip flexors include lunges, which work the lead glute and quad muscles, including the rectus femoris, which is also a hip flexor. They also stretch the hip flexors on the rear leg. From a standing position, take a generous step forward with your right foot. Keep your trunk upright and bend your extended knee, transferring your weight onto your right leg. Slowly lower yourself into the lunge until your left knee hovers just above or softly touches the floor. Your right knee should be directly above your right ankle. Step back into a standing position and repeat with the left leg in front.
Additionally, side-lying banded hip flexion can be performed by lying on your side and replicating the swing phase of running when the hip flexors are most active. This exercise is best done through a doorway, as the wall helps stabilize your back and pelvis and prevents it from rolling backward. Ensure a good lumbopelvic position by not letting the pelvis tilt forward when the hip is extended behind you.
Incorporating these exercises into your routine can help improve hip flexor strength and overall athletic performance while reducing the risk of injury.

Glutes and hamstrings: stretching these muscles can improve your range of motion
The glutes and hamstrings are two muscle groups that play a crucial role in various everyday movements, such as walking, climbing stairs, or even standing up from a seated position. Stretching these muscles can provide numerous benefits and improve your overall range of motion in several ways.
Glutes
The gluteal muscles, located in the buttocks region, are attached to bones in the hips, pelvis, back, and legs. Tightness in the glutes can lead to tension and pain not only in the buttocks but also in the surrounding areas, including the back, hips, and pelvis. Glute stretches can help ease muscle tightness and tension, improving your flexibility and range of motion. For instance, the seated figure-four stretch helps loosen the glutes and surrounding muscles. Additionally, glute stretches can reduce lower back pain and improve overall mobility, making it easier to perform daily tasks.
Hamstrings
The hamstrings are muscles that run along the back of the thigh and play a crucial role in various lower body movements. Hamstring stretches are beneficial for athletes and non-athletes alike. These stretches help improve blood flow, keeping the muscles energised and flexible. By practising hamstring stretches, individuals can improve their flexibility and range of motion, reducing the risk of injury.
Precautions
It is important to note that stretching should be done correctly to avoid injury. Warming up before stretching is crucial, as it increases heart rate and blood flow, supplying the muscles with oxygen and preparing them for movement. Dynamic stretching, which involves performing similar movements to a sport or exercise at a slower pace, is an effective way to warm up the glutes and hamstrings. Additionally, individuals should be mindful of their limits when stretching and avoid overstretching, as it can cause muscle strain or tear. Consulting a doctor or physical therapist before starting a stretching routine is advisable, especially for those with injuries or specific health conditions.

Leg-hip raises: strengthen rectus abdominis and internal/external oblique muscles
Leg-hip raises are an excellent way to strengthen the rectus abdominis, internal, and external oblique muscles, which are crucial for raising the knee and improving overall stability. The rectus abdominis is a deep abdominal muscle that runs vertically along the stomach, providing support and facilitating various movements. By performing leg-hip raises, you can target and strengthen this muscle, enhancing core stability and improving your ability to control movements that involve raising the knee.
To perform a basic leg-hip raise, start by lying on your back with your legs extended. Engage your core to stabilize your spine and pelvis. Then, simultaneously lift your legs and hips off the ground, forming a "V" shape with your body. Keep your legs straight and your core engaged throughout the movement. Lower your legs and hips back down to the starting position, controlling the movement. Aim for 2-3 sets of 10-15 repetitions.
As you become more comfortable with the basic leg-hip raise, you can increase the challenge by adding weight to the exercise. Hold a small dumbbell or medicine ball between your feet to intensify the workout. Additionally, you can perform the exercise in a suspended position to allow for more freedom of movement in the pelvis, further engaging the target muscles.
It's important to maintain proper form throughout the exercise to ensure effectiveness and avoid injury. Focus on engaging your core and stabilizing your spine and pelvis during each repetition. Avoid compensating by using momentum or other muscle groups. If you feel any discomfort or strain, adjust your form or consult a fitness professional for guidance.
In addition to strengthening the rectus abdominis, leg-hip raises also target the internal and external oblique muscles. These muscles are crucial for providing lateral support and facilitating movements that involve twisting and rotating the torso. By strengthening these oblique muscles, you improve your core stability and enhance your ability to generate power from your midsection during athletic activities.

Extensors: muscles that extend your knee out
The knee joint is the largest joint in the body and is made up of several bones, muscles, ligaments, and nerves. The knee joint is a synovial joint, which means it has the most freedom to move. The knee joint consists of the end of the femur bone (thigh bone) connecting with the tibia (shin bone) and fibula. The two main actions of the knee are flexion and extension.
Extensors are muscles that work opposite to flexors, allowing you to extend your knee out. The extensors that control the knee include the biceps femoris, semitendinosus, semimembranosus, and gastrocnemius. These muscles enable movements that require extending the knee, such as kicking or straightening the leg.
The biceps femoris is one of the two heads of the biceps muscle in the back of the thigh. It is responsible for flexing the knee and extending the hip. The semitendinosus and semimembranosus are two muscles located at the back of the thigh that work together to extend the knee and flex the hip.
The gastrocnemius is a large muscle located at the back of the lower leg. It is one of the two muscles that make up the calf, with the other being the soleus. The gastrocnemius is involved in both flexion and extension of the knee, as well as ankle plantar flexion, which is pointing the toes downward.
Strengthening the extensors and other leg muscles can be achieved through various exercises, such as leg raises, lunges, squats, and calf raises. These exercises can improve stability, balance, and overall leg strength, which is essential for activities like running, jumping, and sports that require lower body strength and endurance.
