Did you know that about 5% to 28% of injuries among high-risk sport-specific groups are related to hip flexors? You are probably not an athlete in a high-risk sport-specific group, but if you want to enjoy exercise and avoid injuries during resistance training, it’s expedient to perform some hip flexor exercises. 

There are many exercise options to strengthen your hip flexors, especially since you use this muscle group every day when you move around. To make things easier for you, we’ve outlined some of the most effective ones that can help you make progress faster. Let’s get into it!

What are the hip flexors?

The hip flexors are a group of muscles located near the top of your thighs that allow you to lift your knees toward your torso and bend at the waist. According to the American Hip Institute, the hip flexors are primarily made up of five muscles: the psoas major, the iliacus, the rectus femoris, the pectineus, and the sartorius. 

Together, these muscles support a wide range of movement. If you don’t strengthen or stretch them properly, they can become tight or weak, potentially leading to discomfort or injury.

Improved athletic performance 

Strong hip flexors contribute to better speed, agility, and power in sports that involve running, jumping, or kicking. They help you generate more force when lifting your knees, leading to faster sprints and higher jumps. Research shows that increased hip flexion strength can also improve the speed and agility performance of physically active, untrained individuals.

Enhanced stability and balance 

Hip flexors support the pelvis and lower spine, helping maintain stability during movements, such as walking, running, and standing on one leg. This means that stronger hip flexors will increase the body’s stability, making such activities even easier. 

Better posture 

Hip flexors play a key role in maintaining proper posture. Strong, balanced hip flexors can help prevent the pelvis from tilting forward, reducing the risk of developing lower back pain and improving body alignment.

How to tell if your hip flexors are weak

There are signs that are indicative of weak hip flexors. Some of them are difficulty lifting your knees, lower back pain, hip pain or tightness, poor posture, an imbalanced gait, and difficulty with physical activities that involve hip flexion, like running and squatting. 

These signs may not always mean that a person has weak hip flexors. Nonetheless, if you experience any of these, incorporating some hip-strengthening exercises would be erring on the side of caution.

5 exercises for stronger hip flexors

Kettlebell swings

Instructions:

  • Stand with feet at least shoulder-width apart and place the kettlebell in front of you. 
  • Bend your knees slightly and hinge at the hips to pick it up. 
  • Swing back, pulling the kettlebell between your legs. 
  • Swing forward, pushing your hips forward to swing the kettlebell up to chest height.
  • Return to the starting position with the kettlebell in between your legs and continue swinging back and forth. 

Recommended sets and reps: 3 to 4 sets of 10 to 15 reps

Iliopsoas march

Instructions:

  • Lie on your back, resting on the floor with your knees bent and feet flat on the ground. You could place a band around your ankles for extra resistance. 
  • Tighten your abdominal muscles to stabilize your lower back. 
  • Slowly raise one knee toward your chest, keeping your lower back flat. 
  • Bring your foot back to the starting position and repeat the movement with the other leg. 
  • Continue alternating legs in a controlled, marching motion. 

Recommended sets and reps: 2 to 3 sets of 10 to 12 reps for each leg

Banded hip flexion

Instructions:

  • Secure one end of a resistance band to a low anchor point, like the leg of a heavy table or a sturdy piece of furniture. 
  • Step into the band with one foot, placing it around the top of your foot or ankle. 
  • Face the anchor point and stand tall with your core engaged and feet hip-width apart. 
  • Slowly raise the leg with the band, bringing your knee toward your chest while keeping your back straight. 
  • Gradually return your leg to the starting position. 
  • Complete the reps for one leg, then switch to the other leg. 

Recommended sets and reps: 2 to 3 sets of 12 to 15 reps for each leg

Hip flexor march

Instructions:

  • Stand with your feet hip-width apart, and keep your core engaged. You could place a band in between your legs for added resistance. 
  • Raise one knee as high as you can toward your chest, balancing on the opposite leg. 
  • Slowly bring your leg back down to the ground. 
  • Raise the opposite knee in the same way. 
  • Continue alternating knees in a controlled, marching motion.

Recommended sets and reps: 2 to 3 sets of 10 to 15 reps

Mountain climbers

Instructions:

  • Get into a plank position with your hands straight, directly under your shoulders. 
  • Quickly pull one knee toward your chest while keeping your core tight. 
  • As you extend the first leg back to the starting position, bring the other knee forward. 
  • Continue alternating legs in a running motion, keeping the hips low and your back flat. 

Recommended sets and reps: 3 to 4 sets of 20 to 30 reps per leg

Frequently asked questions

Should I stretch a sore hip flexor?

Stretching a sore hip flexor will help alleviate tightness and improve flexibility. Focus on light, pain-free stretches and avoid overextending the muscle to prevent further strain.

Does walking strengthen hip flexors?

Walking can help strengthen hip flexors, especially when you focus on lifting your knees higher with each step. However, targeted exercises are more effective for building strength in these muscles.

How long does it take to fix weak hip flexors?

Noticing improvements in weak hip flexors could take anywhere from weeks to months, depending on how consistently you train and stretch the muscles. Other factors, like the individual’s fitness levels, may also affect progress.

Fitness gurus recommend growing those glutes with the hip thrust — here’s why
Research shows the hip thrust is more effective at training the glutes for sprinting compared to the split squat or back squat.

The hip thrust lights up your glutes and hamstrings to strengthen and sculpt these major muscles. It’s a weighted variation of the glute bridge where your back is elevated up off the floor. Fitness gurus recommend the weighted hip thrust to primarily work your gluteus maximus, gluteus medius, and hamstrings while also engaging your quads, core, and adductors.
How to do the hip thrust

It’s best to start by mastering the basic bridge before attempting the weighted hip thrust. Always start with lighter weights and work your way up as you develop strength over time.

Should your muscles shake during a workout? Is it healthy or harmful?
To shake or not to shake? Should you stop or continue?

Some fitness instructors and enthusiasts say you should push through the shaking when you're working out because it’s a sign you’re making progress, while others warn that it’s a ‘yellow light’ or even a ‘red light’ that means you should stop. To shake or not to shake? Should you stop or continue? 
A sign of weakness or muscle fatigue?

I had a personal experience with this when I was going through physical therapy, trying to strengthen atrophied muscles in my left side that were far weaker than my right side. I wasn't able to walk on that left leg for a year and a half, so the muscles were definitely a lot weaker at the time. My quad muscles would shake even trying to balance and lower down on my left leg or perform a simple heel tap on that one side. I even began quietly singing to myself the 1960s ‘Jump in the Line Shake, Senora’ calypso song by Lord Kitchener, while watching my quad muscle shake and trying to balance.

Train like a pro: Jack Nunn’s tips for using rowing to boost your fitness
The rowing machine is a low-impact cardiovascular workout that engages multiple muscle groups

Rowing on the gym machine or the glossy water is an excellent low-impact cardiovascular workout that engages and strengthens multiple muscle groups in your arms, legs, core, and back. Ergometers or rowing machines simulate the resistance and the movement of rowing on water, and they remain one of the most popular workout machines at almost every gym you go to for good reason. 

As well as providing benefits like torching calories and enhancing strength, flexibility, and endurance, I also love the feeling of stretching and working my shoulders and back. The next time you try rowing on the water, you’ll notice a boost in your rowing abilities. Plus, it’s an interesting change from the treadmill, elliptical, or exercise bike. Research shows that rowing five days a week for six weeks reduces total body fat percentage, fat mass, and cholesterol and increases back strength and trunk flexion.
