Sit on floor with knees bent and shins stacked with right leg on top. Use your hand to position right ankle on left knee. Ideally, the right knee will rest on the left thigh, but if your hips are tight, your right knee may point up toward the ceiling (overtime, as your hips become more open, your knee will lower). Keeping your hips squared to the front of the room, hinge at the hips and slowly walk hands slightly forward. If this is enough of a stretch, hold here, or fold your torso over your thighs to go deeper. Hold for at least 30 seconds, then repeat on opposite side.
The sartorius supports the more powerful iliopsoas and rectus femoris in accomplishing hip flexion. This long, narrow muscle arises from the front of your hipbone, crosses your front thigh and inner knee and inserts at the top of your shinbone. The unique position of the sartorius enables it to support other leg motions, including knee extension, leg rotation and outward thigh movement. Sartorius strains, which commonly occur in runners and hurdlers, usually occur where the muscle arises at the hipbone. Pain and leg weakness are common symptoms. As with the other hip flexors, stretching and strengthening exercises serve as good preventive measures.
Fun fact: I was hoping I could rename this because I have a phobia of butterflies. But.. I want you to be able to easily recognize this gym class favorite, so here we are. When it comes to hip flexor stretches, this is hands-down the most embarrassing for me- your knees should be much lower to the ground than mine, but that takes time. Work in progress, friends.
Luckily, you don’t have to quit your day job or forgo spin class to loosen them up. Simply stretching those hips can get your body back in alignment, increase your mobility (and thus your exercise performance) and maybe even ease pesky back pain, Moore says. “Given the amount of time we sit [each] day and the stress we put our bodies under, hip-opening moves are a necessary party of our daily routine.”
Well, most of us work the hip flexors (including the psoas and iliacus) most of the time- sitting, practicing while seated, cycling, driving...but only in a limited range, i.e. knees and hips bent to 90 degrees. We need to balance out the movements of the hips a bit more- add more extension and more varieties of flexion. For example, sitting cross legged, sitting on the floor, squatting, kneeling, etc. all require more varieties of hip movement. To get more hip extension in your life, you can add some restorative exercises like standing apanasana, lunges (lots of lunges!) and go walk (not on a treadmill). That way, you don't lose your capacity to move those joints to their full capacity, and you will have loaded the tissues in more diverse ways.
There is no simple orthosis for the management of isolated paralysis of the hip flexor muscles. While the hip guidance and reciprocating gait orthoses mechanically assist hip flexion (see p. 115), neither is prescribed solely for this purpose. Rather they are prescribed for patients with extensive bilateral lower limb paralysis who also require orthotic support around the knees and ankles.
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.
When a muscle contracts, it shortens. Take the biceps for example. Without getting too technical, the biceps are attached at the forearm and shoulder. When your biceps contract, they shorten and bring those two points closer together. When you rest, the muscle returns to its normal length, and the two points move farther away. Constantly contracting your biceps over a long period of time would cause them to get shorter, even at rest.
The hip flexors in particular can be troublesome little cusses. These muscles are crucially tied to the functionality of everyone from elite athletes to senior citizens, but working them can make anyone feel silly. After all, you never see videos of Ronnie Coleman walking with his arms extended in front of him like a zombie, attempting to raise his toes up to his hands.
The top of the sartorius muscle attaches to the anterior superior iliac crest. Anterior is the portion toward the front of the body, superior is the part toward the head, and iliac crest is the top border of the ilium. The muscle crosses the upper leg to attach to the tibia, also known as the shin bone. The femoral nerve supplies the sartorius muscle with nerves. The sartorius muscle aids in knee and hip flexion and rotation of the thigh and tibia.

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.
The hip flexors are the group of muscles that allow you to lift your knees toward your chest and bend forward from the hips. What is collectively referred to as the hip flexors is actually a group of muscles that includes the iliopsoas, the thigh muscles (rectus femoris, Sartorius and tensor fasciae latae), and the inner thigh muscles (adductor longus and brevis, pectineus and gracilis).
The iliopsoas is another powerful hip flexor that begins in two distinct regions proximally. The iliacus has a broad origin, arising from the inner table of the iliac wing, the sacral alae, and the iliolumbar and sacroiliac ligaments. The psoas originates at the lumbar transverse processes, the intervertebral discs, and the adjacent bodies from T12 to L5, in addition to the tendinous arches between these points. Distally, the two large muscular bodies converge to become one distinct structure—the iliopsoas—and subsequently jointly insert at the lesser trochanter of the proximal femur. The nerve to the iliopsoas (i.e., the anterior division of L1 to L3) supplies the iliopsoas muscle.
Start in a runner’s lunge with right leg forward, right knee over right ankle and back leg straight. Walk right foot over toward left hand, then drop right shin and thigh to the floor, making sure to keep right knee in line with right hip. Allow left leg to rest on the floor with top of left foot facing down. Take a moment to square your hips to the front of the room. Hold here, or hinge at hips and lower torso toward floor, allowing head to rest on forearms. Hold for at least 30 seconds, then repeat on opposite side. You want to feel a moderate stretch in the outside of the right thigh, but if this pose hurts your knees or feels too uncomfortable, stick with Thread the Needle.
The hip is a very stable ball and socket type joint with an inherently large range of motion. The hip contains some of the largest muscle in the body as well as some of the smallest. Most people lack mobility due to a relatively sedentary lifestyle. Periods of prolonged sitting results in tightness of the hip flexors and hamstrings. Tightness in the muscles and ligaments can created joint forces that result in arthritis, postural problems, bursitis, and mechanical back pain.
Iliopsoas muscle and tendon strains may occur with activities that require repetitive hip flexion, such as hurdling, uphill running and playing soccer. Deep hip pain is the primary symptom. Hip flexor stretching and strengthening exercises reduce the likelihood of iliopsoas strains. Weighted or unweighted leg raises from a standing, sitting or lying position strengthen the iliopsoas and other hip flexors.
