The Psoas
The psoas muscle is made up of the ‘psoas major’ and ‘psoas minor’, and originates on the lumbar region of the spine and inserts on to the lesser trochanter. In other words…it attaches the lower back (lumbar region) to the inside of the thigh (lesser trochanter). The psoas major assists with flexion and external rotation (bringing the knee up and turning it out) and is also considered a muscle of the hip flexors. A common problem associated with the tightening of this muscle is lower back pain.
Check out the video link below to see where the psoas is located.
