Overhead Press Behind Head Standing

A standing overhead barbell press, performed behind the head, is a compound resistance exercise, which targets the middle deltoids. This exercise can be performed with an Olympic bar or other barbell alternative. It is performed standing and with the barbell lifted behind the head.

The concentric portion of the lift is elbow extension, shoulder flexion and upward rotation and elevation of the scapula as the bar is pressed upward. The eccentric portion is elbow flexion, shoulder extension and scapular depression/downward rotation as the bar is lowered.

The purpose of the standing overhead barbell press, performed behind the head, is to strengthen the middle deltoids while also promoting the hypertrophy (increases in size) of the middle deltoids.

Overhead barbell presses provide a variation in the overhead press that stresses the middle deltoids, promoting increases in their size and strength. When performing behind-the-head presses, the middle deltoids are activated as the elbows flare out to the sides.

Individuals with healthy shoulder joints can greatly benefit from performing overhead barbell presses with the barbell lifted behind the head. The behind-the-head overhead press is a staple exercise for developing the deltoids. Activating the middle deltoids can significantly contribute to overall deltoid aesthetics. Performing this exercise in a standing position increases the difficulty of this lift, requiring optimal trunk strength and stability to execute the exercise safely.

In addition to serving as an exercise that enhances the aesthetics of the deltoids, overhead barbell presses also complement athletic performance as the lifter’s overhead and pushing mechanics are optimized.

The deltoid is a thick, multipennate muscle that forms a curtain around the shoulder. It is the primary muscle involved with arm abduction. When developed, the deltoids give the shoulder their round shape. The external rotation and flexion of the shoulder in this exercise causes the elbows to flare out to the sides, activating the middle fibers of the deltoid. The origin of the deltoid is located at the insertion of the trapezius, lateral third of the clavicle and the acromion spine of the scapula. Its insertion is located at the deltoid tuberosity of the humerus.

The triceps brachii, the primary elbow extensor, is located on the back of the upper arm, originating at the shoulder and inserting in the elbow joint. It consists of three heads, the long, medial and lateral head. The medial head lies beneath the long and lateral head. The long head origin is located at the infraglenoid tubercle of the scapula (shoulder blade). The original of the lateral head is located at the posterior shaft of the humerus. The medial head origin is located at the radial groove of the posterior humeral shaft. The long and lateral heads make up the “horseshoe” portion of the triceps. All three heads merge, sharing insertion into the olecranon process of the ulna, located at the elbow joint.

The anconeus is a short, triangular muscle located at the elbow joint. It is the triceps brachii’s synergist with elbow extension. Its origin is located at the lateral epicondyle of the humerus, inserting at the lateral aspect of the olecranon process of the ulna.

The pectoralis major assists the deltoid with shoulder flexion. The pectoralis major originates at the sternal end the clavicle, sternum and rib cartilage (ribs 1-6) with fibers converging at the insertion located at the greater tubercle of the humerus. The coracobrachialis assists the pectoralis major with shoulder flexion. It is a small muscle originating at the coracoid process of the scapula and inserting half way down the shaft of the humerus. The biceps brachii also assists with shoulder flexion. The biceps brachii is a weak shoulder flexor, however.

The trapezius is the most superficial muscle of the posterior thorax. It is a flat and triangular-shaped muscle. The upper fibers of the trapezius elevate the scapula during this exercise. The origin of the trapezius is located at the occipital bone of the posterior skull, the ligamentum nuchae located behind the neck, and at the spines of C7 and all thoracic vertebrae. Its continuous insertion points are located along the acromion and spine of the scapula and lateral third of the clavicle.

The levator scapulae assists the upper fibers of the trapezius with scapular elevation. It is a strap-like muscle deep to the trapezius located at the back and side of the neck. Its origin is located at the transverse processes of C1-C4. Its insertion is located at the medial border of the scapula, superior to the spine.

The serratus anterior is responsible for upward rotation of eh scapula during this exercise, aiding in arm abduction. It is a fan-shaped muscle that lies deep to the scapula. It also runs deep to pectoral muscles on the lateral rib cage. When well-defined, you can see the serrated/sawtooth appearance of this muscle below the axilla. Its origin is located at rib 1 through 8 (sometimes 9) by a series of muscle slips. Its insertion is located at the vertebral border of the scapula, covering the entire anterior surface.

The wrist flexors and rotator cuff muscles play an essential role in stabilizing the wrists and shoulder joint, respectively, during this exercise.

Seated overhead barbell press, overhead barbell press (in front of the head), overhead dumbbell press, cable shoulder press, shoulder press machine.

Strategically incorporating exercises that strengthen the wrists and, in particular, the rotator cuff muscles into your training regimen will promote optimal performance and safety with overhead press exercises.

Performing seated overhead presses behind-the-head will help isolate the effort of your upper extremity, improving your overall performance of this compound lift.

Focus on the concentric portion of the contraction, concentrating on “squeezing” as bar reaches its highest level overhead.

Emphasis on eccentric contractions, prolonging the eccentric portion of the contraction, may also be incorporated in a training program focused on increasing strength. This should be implemented accordingly and with adequate muscle recovery as eccentric contractions cause substantial damage to muscle tissue.

It’s important to note that your repetition and set volume will depend on your goals (e.g. strength, hypertrophy, muscular endurance). It is also important to allow adequate recovery days in between triceps and chest training to allow muscles to repair.

Starting this exercise with the bar too low behind your head can place the shoulder in a compromising position (increasing the risk of injury) as the bar is lifted. Lowering it too low on the eccentric portion can also increase the risk of injury. Preventing the bar from going to low not only prevents injury, but also optimizes the activation of the middle deltoids when the barbell is pressed behind the head.1

Avoiding overhead barbell presses behind the head because they are dangerous is a common misconception. Lifting the bar behind your head places the shoulder in an externally rotated position. If you have a history of shoulder injury or perform the exercise incorrectly, this position can increase the risk of injury and may opt for dumbbell overhead presses or in-front-of-the-face overhead presses. Behind-the-head overhead barbell presses are recognized as a safe exercise for men and women with a healthy shoulder girdle, uncompromised shoulder range of motion (ROM) and an uninjured and stable trunk when adhering to proper technique.2
Avoid bending your torso backward as the bar is lifted. Not only does this minimize the contraction of working muscles, but also places stress of the vertebral column, increasing the risk of lower back injury.

Do not use body momentum to lift bar during concentric phases. The concentric and eccentric phases should be slow and controlled.

If proper technique is not adhered to the likelihood of injury increases. If the lifter has a compromised range of motion with the shoulder joint, this exercise can increase the risk of injury and/or exacerbate a previous injury. It is also important that the lifter has proper trunk stability to perform this exercise to prevent back or neck injury.

If proper technique and recovery are not adhered to, impingement syndrome, rotator cuff injuries, and glenoid labrum tears may result. Therefore, it’s best to avoid overhead press exercises when addressing impingement syndrome/rotator cuff injury unless advised by a physical therapist.
