Decline Triceps Extension

Lie on your back on a decline bench, your feet securely hooked under the supports. Grab (or have someone hand you) an EZ-curl bar with an overhand grip, your hands a bit narrower than shoulder-width apart. Hold the bar over your chin at arm’s length.  
 
Lower the bar to your head by bending your elbows while keeping your upper arms still.
 
Pause, then raise the bar back to the starting position by straightening your arms.
