Stand with your feet wider than hips-width apart, toes slightly pointing out. Squat down, and hold a kettlebell with both hands between your legs. Make sure your back is flat and your abs are engaged.
As you inhale, press into your feet and explode up, straightening your legs and swinging the kettlebell in front so your hands are in line with your shoulders.
Exhale, and with control, come back to the starting position, allowing the kettlebell to swing back between your legs.
