Instructions:
- 1Lie down on your back with your legs extended straight into the air
- 2Place your hands behind your head, engage your abs, and lift your shoulders off the floor
- 3Twist your upper body to the right as you pull your right knee in as fast as you can
- 4Switch sides and repeat on the left side, keeping your core engaged throughout the movement
- 5Continue alternating sides for the desired number of reps
Tips:
- Keep your lower back pressed into the floor during the entire movement

- Don't clasp your hands tightly behind your head. This can strain your neck
- Ensure your movements are being controlled by your abs, not your neck or head
