    Does anyone know what a Pec Dec Machine is good for?

    (See here if you don't know what I'm referring to: http://www.pro-fitness.com/photos/pec_dec_machine.jpg).

    Of course I know that it builds the chest, but does anyone know specifically what part of the chest it's good for?

    Is it true that this machine creates a movement which is impossible to replicate with free weights?

    Many thanks for your thoughts.

    Off the top of my head...pectoralis major then minor with some inclusion of the deltoids, serratus anteriors, lats and if form is correct, your abdominals should always be tight.
    Just a warning, you should take it easy until perfect form is second nature, as with any weight machine. Rotator cuf and other shoulder as well as back injuries can come from using this machine improperly.

    I'm curious about the pectoral dec machine too. I hardly ever use it unless I am away from my own gym and have nothing else to access. Typically, I use free weights for my chest- bench press, incline bench press and dumbbell press. I always thought the machines were good for obtaining muscle definition, but not building muscle. Interested to hear what others say.

    One of the advantages of using a pec dec over doing dumbbell flyes is that there is a greater time under tension. When using the machine your chest muscles are under tension throughout the entire range of motion. When using dumbbells your chest muscles are under little to no tension as the dumbbells come closer together.
