Step by step

Set the bench to a slight decline and lock your feet under the foot pads.
Lie back with a dumbbell in each hand and press them up over your chest with palms facing each other.
Tilt your upper arms slightly back toward your head so the dumbbells sit just past vertical.
Bend at the elbows to lower the dumbbells slowly toward the sides of your head.
Stop when you feel a strong stretch across the back of the upper arms, with the elbows still pointed up.
Extend the arms back to the start by driving through the triceps, keeping the upper arms in place.

Log your sets. After a few weeks you will see whether it is moving. Free.
