💪Hip flexors are not a single muscle group, but five muscles responsible for flexing the hip.
📏The TFL, Rectus Femoris, and Sartorius muscles attach at the hip level, while the Soas and Iliacus muscles can flex the hip higher.
💥Tight hip flexors, particularly the Soas and Iliacus, can cause back pain by pulling on the lumbar spine.
🏋️♀️Testing flexibility and knee bending can determine if tightness exists and if it's due to the quad or hip flexors.
🤔Cramping in the outside of the hip during lifts indicates weakness in the hip flexors.
