Extension (as a definition) increases the angle between the bones in a joint. When you extend your knee, you are straightening your knee from the bent position, increasing the angle between the femur and the shin bones. When you are extending your hip, your leg is essentially moving backwards in space, say 10-20 degrees. When you walk, run, or lunge, you have one hip passing through extension. Now why the fuss about these two words?
My increased knowledge of the biomechanics of hip flexion is one of the most valuable things that I have learned in the past five years. The problem with understanding hip flexion, in general, and the psoas muscle, in particular, is that we use the term hip flexor as a generic term to apply to five muscles, four of which have distinctly different leverage positions from the other one.
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:
Widen your knees ever so slowly until you feel a stretch in your inner thighs. Make sure your ankles are in line with your knees, your hips stacked over your knees, and your feet and calves should be grounded and toes pointed out. Relax your shoulders, and if you’re able to, lower down to your forearms. If you have a yoga block, resting your chest on it will help you release your hips.
Get down on floor and bring your feet together in front of you, bending your knees out to the side. Sit down into your hips, while keeping your back tall and core tight, and push your knees down to the ground. You can place your hands on your feet or the floor behind you, whatever you need to keep your back tall. If your hips are really tight, gravity might be painful enough for you, no extra pushing required.
Keeping your abs engaged, make sure your head is over your heart, and your heart over your hips. Your hips should be centered, which means your back shouldn’t be arched nor your butt tucked under. Try to keep the weight displaced evenly between your hips. Sink into the lunge as your hips relax. Draw your back heel towards the wall behind you. You can lift your hands up, palms facing each other if you’re able. Repeat on the other side.
This stretch opens the abductors and deeply opens the hips and lengthens the adductors while improving balance. Stand straight, holding the back of a chair at your left side. Lift your right knee into your chest, and grab hold of your foot with your right hand. Slowly straighten your leg up along your side, into a standing split. Keep your hand on your foot and lean your torso to the left. Hold this pose for 30 seconds before alternating sides.
I think you should mention that for some people, stretching is not the solution and that it will deteriorate their posture. Some people need stretching, but most people I know need to strengthen their "overstretched" hip flexors. Many people can't do a single hanging leg raise.

While each muscle functions slightly differently, their overall combination allow them to flex the hip joint, anteriorly rotate the pelvis, and extend the lumbar spine. Due to its’ attachment on the vertebral bodies of the lumbar spine, the psoas also plays an important role in lumbar spine stabilization (1), an often forgotten function of this muscle.
When these muscles are under constant tension because of ergonomics and habitual postural positioning, they may become tight and shortened. This can result in pulling forward on the lumbar vertebrae, creating hyperlordosis and causing the pelvis to tilt anteriorly. This is commonly seen in people who maintain a seated position for a prolonged period such as office workers, computer programmers, and others who find themselves sitting at a desk for hours every day. It is important to provide education on proper ergonomics, movement, and self-care to these individuals.
Approximately 15 degrees of hip extension is required to walk normally. If hip flexors are tight then in order to walk, compensatory movement needs to take place through the lower back causing back pain and premature disc degeneration. Like other joints, if we fail to take them through their full range on a regular basis we eventually lose mobility.
3. Hug it out. Start the supine hip flexor stretch the same as the glute bridge, but keep the right leg relaxed on the floor. Pull shoulder blades down and back to lift hips. Grab the back thigh of the left leg and pull the knee toward the chest. Keep the right leg straight and push its heel into the floor (to feel it in the butt). Hold for 30-45 seconds and switch legs.
I’m a runner and started experiencing some familiar tightness in my hip and started getting worse everyday I ran. It’s always gotten sore after running for a long extent for the last 4 years or so. I’m glad I found this page because all of these stretches helped me realize what needed to be stretched and how tight I really was! I hope this will fix my overwhelming soreness. Thank you!
