Stand with your feet hip width apart, holding a kettlebell in your left hand between your legs. Keep your core braced and your gaze straight ahead as you lean forward, bending at the knee and hingeing your hips back until the kettlebell is hovering just a few inches off the floor. This is your start position. Begin the movement by extending at the knees and hips then driving yourself up as you pull the kettlebell up. At the top, rotate your wrist so the kettlebell flips to the other side of your hand. Bend at the knees again with a slight lowering of the hips then drive yourself back up to create momentum. Drive the kettlebell straight up overhead. Carefully reverse the movement, bringing the kettlebell back to the floor and then alternate arms and perform the sequence again. Continue alternating arms for the required number of reps (or time).
