Pec Dec Fly Gym Machine

A machine fly, alternatively called a seated lever fly or "Pec Deck" fly is a strength training exercise based on the free weight chest fly. As with the chest fly, the hand and arm move through an arc while the elbow is kept at a constant angle.“The pec deck works both your chest and its supporting muscles, primarily your pectoralis major, which is the muscle that allows you to swing and bring your arms together,” explains Caleb Backe, a certified personal trainer and health and wellness expert for Maple Holistics.The fly machine is ideal for increasing chest strength and muscle mass by targeting the pectoralis muscles. You have two sets of pectoral muscles on each side of the front of your chest: the pectoralis major and the pectoralis minor.
