Instructions

1

Lie supine on a flat surface with legs extended horizontally, body suspended or supported with hands behind head or across chest, maintaining a neutral spine alignment throughout the movement

2

Engage core muscles and establish a stable position with hands either supporting the head lightly or crossed over the chest to avoid neck strain; ensure legs remain straight and parallel to the ground

3

Lower the torso and legs simultaneously in a controlled manner by extending the hip flexors and lengthening the abdominal muscles, creating a hollow body position as you descend toward the starting supine position

4

Drive through the abdominal muscles to flex the spine and lift the torso toward the thighs while simultaneously raising the legs, bringing knees toward chest and shoulders off the ground, returning to the hollow body position at the top

Reduces the likelihood of Waist injuries by reinforcing connective tissue strength.

Common Mistakes

Failing to achieve a full range of motion, which drastically limits Rectus Abdominis engagement.
Using excessive momentum to swing the Body weight rather than controlling the eccentric phase.
Shrugging the shoulders or compensating with secondary muscles rather than isolating the Rectus Abdominis.
Rushing the repetition tempo instead of focusing on the mind-muscle connection with the Waist.

Muscle Anatomy
