1
Lie on your back on a mat with knees bent and feet flat on the floor, positioned hip-width apart. Head and neck are neutral, arms extended along sides or crossed over chest.
2
Engage your core by drawing the abdominal muscles inward. Position yourself to prepare for leg and torso movement through abdominal contraction rather than momentum.
3
Lower the legs with control toward the floor while keeping the lower back pressed to the mat, maintaining tension in the abdominals throughout the eccentric phase. Lower only as far as proper form allows without arching the spine.
4
Drive the legs upward and curl the torso toward the legs through abdominal contraction, lifting the shoulder blades off the floor and bringing knees toward chest. Return to starting position with controlled movement.
