Stand with the feet about shoulder-width apart and grip one kettbell in each hand while they are on the ground inside the feet. Pick up both at the same time. Hold one kettlebell in each arm on the chest near the shoulder, with the elbows close to the rib cage and the wrists bent to keep the kettlebell held firmly to the forearm. Keep the back tall and bend the knees to dip slightly at the hips before explosively pushing both feet into the floor and snapping the hips forward to punch both arms straight into the air. As the arms reach full extension, stand straight up. Slowly lower both weights by pulling the elbows down to the rib cage to bring the kettlebells back to the original racked position on the chest and shoulders.
