Work on the Psoas in Session 5

Work on the Psoas in Session 5

The psoas (pronounced so-az) is one of the most important muscles in the body, yet perhaps you've never heard of it. In a cow, it is the cut of meat called the tenderloin. The psoas starts on the front of the lower back vertebrae and attaches on the upper inner leg, very close to the adductor muscles from Session 4. One purpose of Session 5 is to continue the line of support from the inner leg up to the front of the spine. Another important purpose is to get the psoas functioning properly, so it can lengthen and then fire appropriately as you walk.
