The psoas, our primary hip flexor, is usually the weakest of the five flexors, and the other four hip flexors have to work more as a result. To test if this is the case for you, lift one knee well above 90 degrees and hold it there, ensuring that you do not compensate by moving your pelvis or leaning forward. If holding this for more than a few seconds is painful or impossible for you, your psoas suck. You are going to have serious trouble squatting to parallel or lower if these muscles can't do their job properly.
Your skeletal, smooth and cardiac muscles work together to keep your body running like a machine. Within this muscular system there are various parts, from muscle fibers to ligaments. You may know about hamstrings, quadriceps and abdominal muscles, but there hundreds of muscles that move within your body. Some are involuntary, like parts of your digestive system, while you control others whenever you go for a walk or lift weights.
While leg lifts, certain ab exercises, and even hula hooping can all help work the hips, the hip flexors can still be a tricky part of the body to stretch Kinetics of hula hooping: An inverse dynamics analysis. Cluff, T., Robertson, D.G., and Balasubramaniam, R. School of Human Kinetics, University of Ottawa, Ottawa, Ontario, Canada. Human Movement Science, 2008 Aug; 27 (4): 622-35.. To get them even stronger and more flexible, try these five simple hip flexor stretches:
Other muscles that can be recruited to assist with hip flexion include the tensor fascia latae (TFL), the pectineus, the adductors, the gracilis, and the anterior aspects of the gluteus medius and the gluteus minimus. The contribution of these secondary hip flexors largely depends on the position of the hip at the time at which movement is initiated.

Apply the above concept to your hips. When you sit, your hips are in a "flexed" position. Therefore, the muscles that flex your hips are in a shortened state. You probably spend at least a third of your day sitting down. Think about how much time those hip flexor muscles stay shortened. A lot. Over time, they become tighter and tighter until you look like the old man in the picture. So unless you want to look like that, perform the stretches shown below.


#BulletProofMobility RELEASE IN NINE DAYS!!! This bridge variation takes the standard glute bridge to the next level. Much more glute activation when performed with the opposite hip held close to your body. Great strengthener and glute activation warm up movement.

Start in a runner’s lunge, right leg forward with knee over ankle and left knee on ground with top of your foot flat on the mat. Slowly lift torso and rest hands lightly on right thigh. Lean hips forward slightly, keeping right knee behind toes, and feel the stretch in the left hip flexor. Hold here, or for a deeper stretch, raise arms overhead, biceps by ears. Hold for at least 30 seconds, then repeat on opposite side.
Like quadriceps, the hamstrings are 2-joint muscles. Unlike the quadriceps, though, the hamstrings reside at the back of your thigh. They attach at the siting bones, which are located on the underside of your pelvis. When the hamstring muscles contract, the effect is a pulling of the back of the pelvis down toward the back of the thigh, or a bringing of the lower extremity back behind you.
Like most of us in the profession, I did not previously make any distinction among members of the hip flexor group. All of the hip flexor muscles seemed to work together to flex the hip and that, at the time, was enough for me. However, my recent reading into the work of physical therapist Shirley Sahrmann has changed my thinking about hip flexors, as it has about many other muscle groups.
If you suffer from tight hips, I’ve compiled the best stretches and exercises to help you get the relief you need! Whether your hips are tight from sitting all day or from killing your last workout, these hip flexor stretches should help you get some relief. Tight muscles can potentially be shortened, and tight hips might mean your abs are weak or you have some instability in your back. Let’s stretch these babies out and help you work to get balanced and feeling better!
Start in a runner’s lunge, right leg forward with knee over ankle and left knee on ground with top of your foot flat on the mat. Slowly lift torso and rest hands lightly on right thigh. Lean hips forward slightly, keeping right knee behind toes, and feel the stretch in the left hip flexor. Hold here, or for a deeper stretch, raise arms overhead, biceps by ears.

The primary hip flexors are the rectus femoris, iliacus, psoas, iliocapsularis, and sartorius muscles. The rectus femoris muscle has two distinct origins proximally: the direct head and the reflected head. They originate at the AIIS and the anterior acetabular rim (in close proximity to the anterior hip capsule), respectively. The tendinous fibers of the rectus femoris coalesce distally and become confluent with the other quadriceps musculature in the thigh. The quadriceps consists of four distinct muscles: 1) the vastus intermedius; 2) the vastus lateralis; 3) the vastus medialis; and 4) the rectus femoris. The rectus femoris is the only quadriceps muscle that traverses both the hip and the knee joint. The rectus femoris is a powerful hip flexor, but it is largely dependent on the position of the knee and hip to assert its influence. It is most powerful when the knee is flexed, whereas significant power is lost when the knee is extended. The rectus femoris is innervated by the femoral nerve (i.e., the posterior division of L2 to L4).

The term iliopsoas refers to the iliacus and psoas muscles, which are grouped together because they function collaboratively and share a common tendon. The psoas originates from your lower spine, and the iliacus arises from the inside of your hipbone. The muscles come together as they cross through the pelvis and insert on the inner thighbone below the hip joint. The iliopsoas is the most powerful hip flexor.


Located deep in the front of the hip and connecting the leg, pelvis, and abdomen, the hip flexors— surprise, surprise— flex the hip. But despite being some of the most powerful muscles in our bodies (with a clearly important role), it’s easy to neglect our poor hip flexors— often without even knowing it. It turns out just working at a desk all day (guilty!) can really weaken hip flexors since they tend to shorten up while in a seated position. This tightness disrupts good posture and is a common cause of lower back pain. Weakened hip flexors can also increase the risk of foot, ankle, and knee injuries (especially among runners) Hip muscle weakness and overuse injuries in recreational runners. Niemuth, P.E., Johnson, R.J., Myers, M.J., et al. Rocky Mountain University of Health Professions, Provo, VT. Clinical Journal of Sport Medicine, 2005 Jan; 15 (1): 14-21.. So be sure to get up, stand up every hour or so! And giving the hip flexors some extra attention is not just about injury prevention. Adding power to workouts, working toward greater flexibility, and getting speedier while running is also, as they say, all in the hips The effect of walking speed on muscle function and mechanical energetics.

The wisdom that Sahrmann shares in her book Diagnosis and Treatment of Movement Impairment Syndromes explains many of the injury riddles of the Strength and Conditioning field, particularly the “hip flexor pull” or “quad pull.” The key to understanding the motion of hip flexion comes from looking at the anatomical leverages of the different muscles involved. There are five muscles that are capable of assisting in hip flexion:
Lie faceup with knees bent and feet flat on the floor, arms resting at sides. Press into heels and engage glutes to lift hips. Transfer weight to left leg and extend right leg straight out for five breaths. Inhale as you lower right leg to hover over floor for five breaths, then exhale as you lift it back up. Perform 8 reps, then repeat on opposite leg.
I like to think of myself as a powerful, modern Highland warrior, or maybe a Viking. Had I been born 1,100 years ago I would have leapt first off the longboat to battle hundreds of enemies with a giant axe, or so the fantasy goes. But, it didn't take strength coach Matt Wattles long to put a pin in that balloon. All he had to do was ask me to raise my toes all the way up to his hands, and in an instant, I felt like a senior citizen with a hip replacement. That movement was hard.

Hey Sunny! I’m so sorry you’ve been experience hip pain since your C-section! I hope these help! :) I actually have an exercise program to help women recover properly from C-sections (mainly rebuilding their core and pelvic floor) if that sounds like something you might be interested in, let me know! I’m wondering if we could get your strength balanced some of that hip pain would go away? Thanks so much for your comment!
Come into a lunge position with your right knee forward, and lower your left knee to the ground, releasing so the top of your left foot is flat on the floor. Place your hands on the ground under your shoulders, keeping them both to the inside of your right leg. Keep your arms straight and press your chest forward to increase the stretch. Sink into your hips, but try to keep the weight balanced between them. Be aware that your front knee doesn’t go over your toes. Repeat on the opposite leg.

Keep adjusting your position until you find a hot spot ("A what? I don't know what you're ... Oh! My God! There one is!"), and then hold that position for at least 30 seconds. Your first impulse will be to tense up when you feel tenderness, but it's important that you relax and continue to move around the area. Keep it up, and don't hurry. The more slowly and more often you can do this, the better.

This stretch targets the abductors, opens the hips, and stretches the outer length of the legs and hips. Begin on all fours, with your palms flat on the floor and your toes raised behind you. Extend your right leg straight out to the side, resting your right foot flat on the floor. Press your hips down toward the floor to increase the stretch. Hold this pose for 30 seconds before releasing and performing with the other leg.
