What are the hip flexors, and more important, what do we need them for? There are two important muscles in your hip flexors: one that runs from the spine to the thigh bone that is called the Psoas (pronounced “so-as”) and the other that runs from the pelvic bone to the thigh bone, called the Iliacus. Your hip flexors are critical to perform movements like bending the knee, bringing it close to the chest or stepping forward and walking. They play an important role in your daily activities and that’s why it's important to strengthen and stretch them so you can move uninhibited, pain free and smoothly. Furthermore, because the Psoas is connected to our lumbar spine (lower back), it is common for it to be the source of lower back pain, when it is too weak. In this short video (10m), you will learn how to strengthen your hip flexors and get rid of the pain in your lumbar spine
