Sometimes you want to work out your chest without loading heavy plates onto a bar or heaving bulky dumbbells. In that case, turn to the pec fly machine, also sometimes referred to as the pec deck.
This machine features a padded seat and back rest from which two levers protrude. You sit in the seat and place your arms into the padded levers, drawing your elbows together like you're flapping your wings.
The machine emphasizes your pectoralis major muscle, the broad muscle of the chest, as well as a few helper muscles. It has minimal reach when it comes to muscle activation, though, as it's an isolation exercise, activating just one joint.
