Set-up: With two dumbbells set your feet to roughly shoulder width. Brace your core with a neutral spine, and using an overhand, shoulder-width, grasp the dumbbells and lift them to your shoulders.
Lift: Bracing through your core, push the weights overhead, just shy of locking your elbows at the top. Return the weights to your shoulders under control.
Emphasis: Keep your core and back strong while maintaining natural spine position. While your legs, core and back should work to stabilize the movement, do not drive through the legs or use momentum to complete the lift.
