Lie on your back with your knees bent, holding a kettlebell in each hand.
Face your palms inwards with the weight of the kettlebell resting on the back of your forearms.
Your elbows should be on the floor with the weight directly above.
Drive the kettle bells straight up in line with your shoulders until your arms are locked out.
Return the kettlebells back down to the starting position in a controlled manner and repeat.
