Stand straight, holding EZ-bar with a pronated grip (palms facing forward) from each other. Your wrists are closer than shoulder-width apart. Feet are shoulder-width apart.
Elevate your arms with barbell above your head. Keep your elbows in. This will be your starting position.
Keep your upper arms and the elbows close to your head, perpendicular to the floor. Your elbows should face the torso. Inhaling, lower the barbell in a semicircular motion behind your head. Keep moving until your forearms touch your biceps.
Exhaling, return the barbell to the starting position by contracting the triceps.
