Main muscles working (thicker lines)
Hook your legs under the pads of a decline bench and lie back, holding an EZ bar with a narrow grip and arms straight above the shoulders.
Keep the upper arms still and the elbows in.
Bend the elbows to lower the bar in an arc toward the forehead.
Stop just short of the head.
Extend the elbows to return the bar to lockout.
Breathing: Inhale as you lower, exhale as you extend.
Elbows point at the ceiling
Move only at the elbows
Squeeze at the top
Turning it into a press
Elbows flaring out
Dropping the bar fast toward the head
Use a spotter for the hand-off; the bar travels toward your face.
