Adjust the seat height so that your shoulders are aligned with the top of the padding. Hook your feet under the foot pads and grip the handles securely.

Start the crunch by activating your core and hinge your torso forwards as far as comfortable, then slowly return to the starting position. Keep your lower back constantly against the padding. To target the obliques adjust the Repeat for the desired amount of repetitions.

Avoid using the arms to pull the weights down or rushing repetitions.
