Stand tall holding a barbell overhead with hands about shoulder-width apart. Keeping your upper arms steady and close to your head, bend at the elbows to lower the bar behind your head, then extend the elbows to press the bar back up. Focus on slow, controlled movement to maximize triceps engagement and maintain good posture.
