The psoas is truly an admiral foe. If you overuse it, it will fight back with a vengeance, spasming and leaving you standing crooked and in pain; if you ignore it and allow it to get short and tight it can lead to years of cascading muscle imbalances and injuries. The psoas can be a tough muscle to understand. In part, this is due to the fact that you can’t really understand a muscle in isolation, you need to understand the company that it keeps. What most people think of as one large muscle, is really two. The Iliacus and psoas have different origins, but insert into the same point on the inside of the upper thigh. The psoas originates off of the front of the last thoracic vertebra, and each of the five lumbar vertebrae. The iliacus originates off the inside of the rim of the pelvis. When the psoas is short it pulls the vertebrae forward, and accentuates the backward arch in the low back. When the iliacus is short, it pulls the pelvis forward. Muscles don’t get out of balance on their own. It’s a combination of poor postural habits, sitting for hours at a time, and  weakness in the muscles on the opposite side of the body.
Muscles become strained when they are always taking on too much work. I often seen people with a strained iliacus and psoas and long overstretched hamstrings, weak buttock muscles and weak muscles in the lower belly.  These three groups of muscles help to support the pelvis and spine. Many yoga sequences can excessively over stretch the hamstrings with too many forward folds and ignore the psoas with very few backward bends that control the movement of the pelvis.
Here are three strategies to tame that unruly psoas and bring it back into balance.

  1. evolution_yoga_Psoas_ReleaseGive Your Psoas a Break – For the strained and reactive psoas, you can’t stretch it. It’s already sore and overworked. Stretching the psoas will only cause more irritation to the muscle. Your best strategy is to relax the muscle. Lie on the floor with your legs supported on a chair. Use each exhale to allow the hip creases to become heavy. Imagine the legs sinking into the floor and the low back releasing. Hold this position for 5 minutes. Placing sand bags or bags of rice on the hip creases assists the psoas and iliacus to release. Perform this 1-3 times a day.
  1.  evolution_yoga_psoas_buttStrengthen Your Butt – In order to reduce the work your iliacus and psoas have to do, you need to bring them some help. Think of the hamstrings and gluteus maximus as supporting cast members. When they are shorter (especially important for those over stretched hamstrings), and stronger, the psoas and iliacus don’t have to work as hard. Bridge pose – Lie on your back, bend your knees and bend your elbows to 90 degrees.  Press down with your feet and the upper arms, squeeze your buttocks as you lift your hips.  Gently draw in your belly to keep your back from arching. This lengthens your iliacus and psoas as you strengthen your gluteus maximus.  In order to engage the hamstrings, energetically draw the heels towards the buttocks.  Hold for 5 breaths and lower.  Repeat 3 times or until you feel a slight burn in the buttocks or back of the thighs.
  1. Evolution_yoga_psoas_Vira_oneLengthen your hip flexors – The muscles on the front of the hips and thighs are called your hip flexors. These are the muscles that lift your legs and are comprised of the Iliacus, psoas and rectus femoris (middle muscle on the front of the thigh).  If you spend most of your day sitting, it’s likely that your hip flexors have become short. Gently stretching them can take tension out of your low back and hips. Only try this if stretching your psoas feels good. Step your right leg forward into a high heeled warrior I with both hips facing straight forward. Draw your belly in, to support your spine in a neutral position. Bend the back knee to stop the pelvis from tipping forward.  With the belly engaged, slowly straighten the back knee and push the left hip forward. You should feel a gentle stretch in the front of the left hip. Hold for 5 breaths. Repeat this on either side 3 times per day.
