cable alternate triceps extension

Stand facing the cable machine with your feet shoulder-width apart. Hold the cable handle with your right hand and bring your arm up so that your upper arm is parallel to the ground and your elbow is bent at a 90-degree angle. Keep your upper arm stationary and extend your forearm backward, fully straightening your arm. Pause for a moment, then slowly return to the starting position. Repeat with your left arm. Continue alternating arms for the desired number of repetitions.
