Assume a standing position while holding a kettlebell in each hand with a neutral grip.
Hinge forward until your torso is roughly parallel with the floor (or slightly above) and then begin the movement by driving the elbows behind the body while retracting the shoulder blades.
Pull the kettlebells towards your body until the elbows are at (or just past) the midline and then slowly lower the kettlebells back to the starting position under control.
Repeat for the desired number of repetitions.
