Stand with your feet hip-width apart behind a box or step. A bar is placed on top of posterior shoulder muscles and trapezius (low position) or above posterior shoulder muscles at the base of the neck (high position). Shoulders are pinned back and down. Hands are just outside shoulders or slightly wider.
Step one foot up onto the box and stand up, then lift back leg up and drive knee forward and up. Then lower the leg back on the floor and step off the box.
