Lying on the floor on your back with the kettlebell on one side, grab it by the handle with your hand on that side while supporting the other on the floor. Bend your leg on the same side as you have the kettlebell and stretch your arm completely. Use the other arm as support to slightly rotate the trunk and raise it. Finally use the bent leg as support to lift the hips and hold for a second, before returning to the starting position.
