1
Sit on the floor or mat with your back supported on an incline bench or declined surface. Position your body at approximately 45 degrees with knees bent and feet firmly planted on the ground or secured under a support.
2
Place your hands behind your head with fingers interlaced, elbows out to the sides. Alternatively, cross arms over your chest. Engage your core and prepare for the movement by taking a deep breath.
3
Slowly lower your torso backward by extending through the abdominal muscles, allowing your back to recline toward the bench while maintaining tension. Keep your neck neutral and avoid pulling on your head. Lower until you reach a comfortable range of motion or slight stretch in the abs.
4
Contract your abdominal muscles and pull your torso forward and upward using your core strength, lifting your shoulders toward your hips. Return to the starting seated position with controlled movement, exhaling as you crunch upward. Avoid using momentum from your neck or arms.
