Begin with an overhand grip and your hands just outside shoulder width apart on the bar.
When starting the movement, begin by leading with your elbows and treat your hands as hooks for the bar.
While leading with your elbows towards the ceiling, you want to try and come up to where the bar is just below your chin at the top, and then begin to slowly lower back down to the relaxed position before repeating the movement for the designated amount of reps.
