1
Start in a prone horizontal plank position with body fully extended, arms at sides or slightly forward, legs straight and together, and core engaged to maintain a neutral spine alignment.
2
Prepare by tensing the abdominal muscles and establishing a stable core foundation. Ensure the body forms a straight line from head to heels with no sagging or hyperextension.
3
Lower the body by flexing at the hips and waist, bringing the chest and torso downward in a controlled manner while maintaining core tension and allowing the legs to remain relatively extended or slightly bent.
4
Return to the starting position by extending at the hips and engaging the rectus abdominis to lift the torso upward, returning to the initial prone plank alignment with controlled movement.
