You’re probably most used to noticing the psoas after sitting for an extended period of time (when it tightens up), or doing ab work on your back that involves a lot of leg movement (when it fires up). Psoas weakness and tightness often also manifest in unexpected places, like chronic low-back pain, poor posture, leg-length discrepancy, limited internal/external rotation, sciatica, pelvic floor dysfunction, and even painful sex. Knowing what’s going on in your own body is not only empowering but allows you to focus on what is actually going to make a difference in how you feel long term. Giving your psoas what it needs can not only help improve the efficacy of your fitness routine but also improve your overall quality of life. Below, I’ve compiled some of my favorite moves to both stretch and strengthen that psoas, for some much-needed hip relief.
