The overhead press is one of our four core upper body lifts. It primarily works your deltoids and triceps. By doing it from a standing position, you’ll also be activating your core to keep your body in a strong, balanced position. Bracing your body by tightening your core is important for every lift and every sport. Since the angle of the overhead press focuses the movement on your shoulders instead of your chest, it’s the most important exercise for your shoulder development. Make the overhead press part of your regular routine for a strong, balanced upper body.
