Straight-Leg Crunch

Setup

1. Lie flat on your back on a mat.

2. Extend your legs straight up toward the ceiling, keeping them together and locked if possible.

3. Extend your arms straight up toward your feet, palms facing in.

Execution

1. Engage your core by drawing your belly button toward your spine.

2. Exhale as you lift your shoulder blades off the floor, reaching your fingertips toward your toes.

3. Focus on contracting your abdominal muscles at the top of the movement.

4. Inhale as you slowly lower your shoulders back to the floor, maintaining control throughout the return phase.

5. Keep your legs as still as possible throughout the movement.
