Attach a pair of resistance bands to a door anchor and place the door anchor at the bottom of a door. Attach the workout bar to the other ends of the resistance bands. Grab handles with shoulder width apart using overhand grip.
With elbows to side, lower the workout bar until the bar nearly touches thighs and return to the original position. Repeat.
When elbows are fully flexed, they can travel froward slightly allowing forearms to be no more than vertical. This additional movement allows for relative release of tension in muscles between repetitions.
