Exercise Advice: Attach a v-bar to the top portion of a cable machine. Grab the v-bar with your palms towards each other and position the v-bar at about chest level. Slowly lower the v-bar downward, making sure to keep your elbows in while extending your arms and have a slight bend in your arms when you reach the bottom of the movement. Slowly let the v-bar come back up to the starting position while keeping your elbows in.
