The hanging leg hip raise is an advanced bodyweight core exercise performed from a pull-up bar, raising the legs and then curling the pelvis upward. The hip raise portion is what separates it from a plain leg raise: posterior pelvic tilt at the top is driven by the lower fibers of the rectus abdominis rather than the hip flexors. It also builds serious grip and shoulder stability from the dead hang.
