1
Start in a prone plank position with hands placed shoulder-width apart on a decline bench, feet elevated on the bench behind you, body forming a straight line from head to heels.
2
Secure grip on the bench with hands directly under shoulders, engage core muscles, maintain neutral spine alignment, and prepare for controlled flexion movement.
3
Slowly lower your torso toward the bench by extending through the hip flexors and allowing the spine to extend, creating a controlled eccentric contraction of the abdominals over 2-3 seconds.
4
Drive through the abdominals to flex the spine and lift your torso back to the starting plank position, creating a crunching motion while maintaining stable hip and leg position on the bench.
