The Pec Deck Press machine, or machine fly, is a great piece of gym equipment that allows the user to focus on developing his or her pectoral muscles in the safest way possible. Gripping the pec deck handles, pull your arms toward your body while contracting your pectoral muscles. Bring the handles or arm pads in front of your chest, hold the position for a couple of seconds, and then slowly release back to starting position.

The pec deck press machine is made specifically to isolate the chest muscles, or pectoral muscles during the exercise, thus allowing one to really develop those muscles in particular.
