Reverse Grip One Arm Cable Triceps Pushdowns
Pin the pulley height to its highest setting, pin a suitable weight and position yourself adjacent to the stack.
Take hold of the cable handle with the hand that is closest to the stack, palms facing upward. You should be facing in towards the stack so that the cable handle moves down and toward your legs when you perform the movement. Your core is tight and your feet are flat on the floor at shoulder-width. Your elbow is locked to your side and when you take the weight, your forearm will be angled up toward the cable pulley. This is the starting position.
Commence the movement by squeezing the triceps and extending your arm in a large arc from the chest around to the groin. The elbow acts as a hinge joint - the upper arms should remain stationary, elbow pinned to the side and the movement comes only from the forearm. You should feel a large contraction through the triceps. Exhale through the movement.
When the arm is fully extended and the handle approaches your groin, reverse the movement by returning the arm back to the starting position without lifting your elbow, inhaling as you do.
