Arnold Press

Description

Sit on a low straight-back bench with your feet firmly planted on the floor holding a pair of dumbbells at shoulder height. Begin with your palms facing your shoulders and your elbows down and forward. Push the weights straight up, pronating your hands once the dumbbells reach eye level so that your palms face forward at full arm extension. Control the dumbbells all the way back down in the reverse motion to the start position.
 
Tips
The motion of the arms is sort of a "corkscrew" motion as you press the dumbbells up and lower them back down.
