Crunch (on Bench)

Instructions

1. Sit on the edge of a flat bench and lean back slightly, gripping the sides for support.
2. Place your feet flat on the floor or elevate them slightly for extra challenge.
3. Curl your torso forward, contracting your abdominals and rounding your upper back.
4. Hold at the top for a brief squeeze, then slowly lower back to the start.
5. Keep the movement controlled and avoid using momentum.
