What actions of the abdominal muscle is being exhibited when doing hanging leg raises?

When performing hanging leg raises, the primary action of the abdominal muscles involved is hip flexion, which occurs as the legs are lifted towards the torso. This movement primarily engages the rectus abdominis and the hip flexors, while also activating the obliques for stabilization. As the legs rise, the core muscles contract to maintain balance and control throughout the exercise. Additionally, the hanging position challenges the abdominal muscles to stabilize the pelvis and spine.
