The psoas is one of the largest muscles in the body and connects the lower portion of the spine to the femur (thigh bone). There is one on either side for each leg.
This muscle is so large simply because this is the only muscle that comes into play when your raise your foot. Every single time you lift your knee, the psoas muscle contracts.
There is a link between a tight psoas muscle and chronic back pain. As the psoas muscle connects the spine to the thigh, any tightness in this muscle can alter the shape of the spine. A psoas which is tight will therefore pull the vertebrae of the lower back out of alignment putting pressure on the spinal column.
When one psoas is tighter than the other, it is even worse. This is because, not only will it pull the spine forward but sideways as well, causing excruciating pain.
Every time you lift your knee or lift your body forward, keeping your leg straight, the psoas muscle contracts. Also, every time your leg stretches behind you, the psoas muscle lengthens. Exercises that pull your leg behind you will therefore stretch your psoas muscle. Below we give you a few exercises that will help relieve tight psoas muscles.
The warrior pose is one of the best ways of relieving a tight psoas muscle.
The Kneeling Lunge is also very effective at relieving a tight psoas. It is easier to do than the Warrior Pose and is probably better for older or overweight people.
The Thomas Stretch is used by doctors to check the flexibility of the hip. It is, however, a very good psoas stretch when held for 30 to 60 seconds.
Below are a few tips to avoid tight psoas
Many people pay no regard to the wear and tear which the body goes through when performing strenuous exercises. Unless you have a good trainer who knows how to help your relax after a session of core exercises, you may very well end up injuring your psoas muscles, which, in turn, will lead to considerable back and spine-related injuries and pain.
