Pec Dec Machine
Most gyms will have one of these machines. They are used to help with chest development, in a similar way to dumbell flyes. Set the machine up so that when you are in the relaxed position, arms stretched back, there is still tension on the weight. This will ensure that throughout the movement there is always tension on the muscle and thus stop the muscle from being able to take a break at the end of each rep. The best way to do this exercise is slowly, with good form, and hold when your arms are out in front of you for a couple of seconds, getting a good contraction in the chest.
