How to do it
Stand tall, then step one foot back into a slight lunge while swinging both arms up and out to the sides like a flapping motion. Return to center as you lower the arms, then alternate the stepping leg in a continuous rhythm. Keep your chest up and your core engaged throughout.
- 1Your glutes and quads loading as you step back
- 2Your shoulders and upper back driving the arm flap
- 3A smooth, coordinated rhythm between legs and arms
Common mistakes
- Letting your front knee collapse inward
- Swinging the arms so hard you lose posture
- Slouching or rounding the upper back
