1
Sit on the floor with knees bent and feet flat. Lean back slightly with torso at approximately 45 degrees. Place hands behind head with fingers lightly supporting the neck, elbows wide.
2
Ensure feet remain in contact with the floor throughout. Maintain a neutral spine position without pulling on the neck. Engage core muscles before initiating movement.
3
Lower the torso backward by extending the spine, allowing the upper back to approach the floor while maintaining bent knees. This is the eccentric or lengthening phase of the abdominal muscles.
4
Contract the abdominal muscles and curl the torso forward, lifting the shoulders off the floor while keeping the lower back in contact with the ground. Return to the starting seated position with knees bent.
