1
Lie supine on a mat or floor with knees bent and feet flat on the ground, positioned hip-width apart. Place hands behind head with elbows extended or crossed over chest. Maintain neutral spine alignment with lower back in contact with the floor.
2
Engage core muscles and prepare for movement. Ensure chin is tucked slightly to maintain neutral neck alignment. Feet should remain anchored to the ground throughout the exercise.
3
Slowly lower legs toward the ground in a controlled manner by extending hip and knee joints. Allow the torso to remain stationary while legs descend. Lower legs until they reach a comfortable position just above the floor, maintaining core tension to prevent lumbar spine hyperextension.
4
Drive through core engagement to lift legs back up to starting position. Use abdominal muscles to flex hips and return legs to bent knee position. Move in a controlled manner without momentum, squeezing abdominals at the top of the movement.
