Main muscles working (thicker lines)
Lie back on a bench set to 45–75 degrees, holding a barbell or EZ bar with a slightly narrower than shoulder-width overhand grip, arms straight and in line with the torso above the head.
Keep the upper arms close to the head and still.
Bend the elbows to lower the bar in an arc behind the head.
Go until the forearms meet the biceps or the stretch stops you.
Extend the elbows to press the bar back overhead and squeeze.
Breathing: Inhale as you lower, exhale as you extend.
Elbows in
Upper arms stay put
Deep stretch, strong lockout
