Triceps cable rope pushdown

Instructions

Attach a rope to the high pulley and grasp it with both hands. Your upper-arms should stick to your body and your forearms should be parallel to the ground.
Push the rope down until your arms are stretched (your hands should be at your sides now). Only the forearms move: the elbows are still and glued to your body.
Hold this position for one second then slowly move up to the starting position.
