Lie on the ground with your feet about two feet from your glutes with your knees bent and a kettlebell in both hands with your arms fully extended.
Engage your core, and begin to lift your shoulders and back off the ground, keeping your arms straight the entire time. Lift up as high as you can, contracting your abdominal muscles throughout the entire movement.
With control, slowly lower your body back down to the starting position, making sure your arms are fully extended and the kettlebell remains above your chest.
