Hip flexors are a group of muscles that run down the front of your upper thigh. The iliacus, psoas major, rectus femoris, and sartorius are among them. The primary hip flexors are the iliacus and psoas major, which work together to flex and stabilize your hip and pull your thigh and torso together when you walk, run, sit, or stand. The rectus femoris aids in hip flexion and knee extension, whereas the sartorius aids in hip flexion, external rotation, and knee flexion. Tight hip flexors make it difficult for your pelvis to rotate properly, which can affect several other areas of your body because the hips connect the lower back to the legs. Pain or discomfort in the front of your hip that worsens with prolonged sitting or repetitive hip-flexion movements like running and cycling are symptoms of tight hip flexors.
