Ferrigno begins his tricep workout with pushdowns. Stand facing the cable machine at the gym. Grasp the handle of the machine with both hands and pull it down to the lower-middle of your chest. Bring your elbows in to your sides and your wrists into line with your forearms. As you exhale, straighten your arms to pull the handle down. As you inhale, bend your elbows again to return to the start position. Keep your elbows tightly against your sides throughout the exercise to work the triceps rather than the lats.
