Lie on the floor on your back with the kettlebell at your side

Grab it by the handle with the hand on that side while resting the other on the ground

Bend the leg on the same side as the kettlebell and fully extend the arm

Use the other arm as support to slightly rotate the trunk and raise it

Finally, use the bent leg as support to raise the hip and hold for a second, before returning to the starting position.
