In addition, your shoulder and core muscles work as stabilizers during this movement. Thus, in the overhead tricep exercise, when the weight is at its lowest point, your triceps are stretched to their greatest length. The tricep muscles attach above the shoulder joint and below the elbow joint. Yet, the overhead tricep extension works the triceps at their most lengthened position. One recent study compared the two exercises and found similar activation of the tricep muscles during the raising and lowering phases (the concentric and eccentric motions, respectively) ( 3). The overhead tricep extension is comparable to performing a tricep pulldown with your elbows at your sides. How it compares with other tricep exercises The overhead tricep extension is an excellent exercise to work this muscle. The triceps extend, or straighten, the elbow, as well as aid the shoulder muscles to extend the arm. Still, overhead tricep extensions are an excellent way to target all three heads, and a great exercise to add to your fitness routine. During overhead tricep presses, the long head tends to be most active during the entire movement ( 2). There are 3 heads to the triceps: the medial, lateral, and long heads. It runs the length of the back of the upper arm to attach to the tip of the elbow, which is called the olecranon process of the ulna ( 1). The muscle originates at the back of the scapula and on the back of the upper arm bone, which is known as the humerus. Additionally, the triceps are important stabilizers in the shoulder joints. The second is helping pull the arm down from an overhead or front-of-body position (shoulder extension). The first is extending, or straightening, the elbow. The triceps brachii is a three-headed muscle that’s involved in two primary actions.
