Bent-Arm Pullover (Barbell)
Also called Bent-Arm Barbell Pullover, BB Bent-Arm Pullover
How to do it
Lie on a flat bench holding a barbell over your chest with a shoulder-width grip and the elbows bent to about 90 degrees. Keeping that elbow angle, lower the bar back over your head until you feel the stretch through the lats, then pull it back over the chest.
