LANCE BUMGARNER: Now, I am going to show you how to do peck deck butterflies. Right here we have a chest fly machine. Most machines are referred to as a peck deck. The peck decks typically have the arm pads on your forearm, so you are bringing the weights around to your chest. I would like to demonstrate how to do a peck deck fly, a chest fly on this machine. You have to adjust the seat to the proper height, making sure the weight is based on your fitness needs. Arms are going to come straight out from your chest. In a slow and in control manner, you are going to want to bring the weights straight around to the middle. Inhale in the return; exhale on the way out. Notice I am not jerking. I am not slinging the weights. Everything is nice and in control. Finish up your set, repeat several more. This is how to do peck deck butterflies on a chest fly machine working your chest and your shoulders.
