Lie on a flat bench and grasp a barbell using a medium grip (about 15” apart).
Place the barbell on your upper thighs and lock your arms straight with a slight bend in your elbows.
Draw your abs in and keeping your back flat on the bench, raise your arms up in an arc over and behind your head (as if you were performing a reverse pullover).
Slowly return the barbell to the starting position on your thighs.
