1. Hold a dumbbell in each hand and stand with your feet shoulder-width apart.
2. Bend your knees slightly and lower the dumbbells down to just above your knees.
3. In one fluid motion, fire your legs and glutes to explosively straighten your hips and shrug your shoulders. Use that momentum to straighten your arms and press the dumbbells above your head.
