Attach a rope to a high pulley and face away from the machine, rope handles gripped overhead with elbows bent and pointing up toward the ceiling. Keep your elbows close to your ears and stationary as you extend your forearms forward and down, straightening your arms without letting your elbows drift out to the sides. Lean your torso slightly forward for balance, but do not use your back to help move the weight. Pause briefly with arms extended, then let your elbows bend back under control, keeping tension on the cable rather than letting the weight stack rest between reps.
