Pec Decks or Butterfly machines

This video shows the basic pec deck exercise. As described the “Butterfly” machine typically has pads where you rest your forearms and the Pec Deck machine uses handles you hold with your hands. Both are effective for isolating the chest muscles. Some believe the Cable Crossover exercise achieves the same exact muscle contraction. It is our belief that the Pec Deck, due to it’s specific circular range of motion, can isolate some parts of the chest in a different way from the standard Cable Crossover, which is also an excellent chest exercise!
