Lying Crunch (Straight Legs)

Instructions

1. Lie on your back with legs fully extended and hands lightly behind your head.
2. Exhale and curl your upper body off the floor, bringing your chest toward your thighs.
3. Keep your legs straight and on the floor throughout the movement.
4. Hold briefly at the top, then lower your shoulders back with control.
5. Avoid pulling on your neck — use your abs to initiate each rep.
