Set-up: Set up a barbell on in a power-rack at roughly shoulder height. Face the barbell and set your feet to roughly shoulder width. Alternatively the weight can be picked up from the floor or racks. Brace your core with a neutral spine, and using an overhand, shoulder-width, grasp the weight and rest it gently at your shoulders.
Lift: Bracing through your core, push the weight overhead, just shy of locking your elbows at the top. Return the weight 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 - using a leg-drive will turn the exercise into a push-press, which is an exercise for another day.
