Bench Press Incline

An incline bench press is a resistance exercise, which involves the primary horizontal shoulder adductor, the pectoralis major. It is a variation of the traditional bench press. This exercise can be performed with an Olympic bar or other barbell alternative. It is performed lying face up on an incline bench.

The concentric portion of the lift is horizontal shoulder adduction and elbow extension, which involves the lifting of the weight. The eccentric portion is horizontal shoulder abduction and elbow flexion, which involves the descent of the weight.

The purpose of the incline bench press is to strengthen the upper portion of the pectoralis major while promoting hypertrophy (increases in size) of this muscle.

Incline bench presses increase the size and strength of the upper (clavicular) head of the pectoralis major. Therefore, the incline bench press helps develop the upper portion of the chest. The triceps and anterior deltoid are also activated in this movement.

The incline bench press serves not only as an exercise to improve aesthetics of the pectoral muscle, but also as a valuable training tool for sports that entail pushing and throwing.

The pectoralis major is a large, fan-shaped muscle that spans across the chest, forming the front portion of the axillary fold (arm pit). It is divided into two parts: clavicular and sternal. Its origin is located at the sternal end of the clavicle, the sternum, rib cartilage (ribs 1-6 [or 7]), and the aponeurosis of the external oblique. The fibers of the pectoralis major converge at the point of insertion located at the greater tubercle of the humerus. The pectoralis major aids in pushing movements as the shoulder adducts the arm against resistance. The shoulder adducts as the barbell is pressed upward.

The inclined positioning of this exercise induces greater activation of the clavicular head of the pectoralis major.1 Therefore, incline bench presses are an effective exercise for developing the upper chest.

The triceps brachii 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 triceps brachii extend the elbow joint. The long head assists in arm adduction as with the bench press pushing motion.

The deltoid is a thick, multipennate muscle that forms a curtain around the shoulder. It is the primary muscle involved with arm abduction and the anterior fibers are a primary shoulder flexor. The anterior deltoid is a primary synergist of the pectoralis. When developed, the deltoids give the shoulder their round shape. 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 anconeus is a short, triangular muscle located at the elbow joint. Its origin is located at the lateral epicondyle of the humerus, inserting at the lateral aspect of the olecranon process of the ulna.

Like the anterior fibers of the deltoid, the coracobrachialis is a synergist pectoralis major with horizontal shoulder adduction. It is a small muscle originating at the coracoid process of the scapula and inserting half way down the shaft of the humerus.

The wrist flexors and extensors stabilize the wrists, the abdominals stabilize the torso and the rotator cuff muscles stabilize the shoulder girdle.

To minimize negative stress on your shoulder joint, it is best to not flare your elbows to the sides when lowering the bar. Maintain your elbows closer to your sides while lowering the bar to prevent shoulder injury. This technique also activates the pectoralis major fibers to a greater extent. Keeping your elbows tucked in your sides will have the bar descending lower in the upper chest area as opposed to the higher level it reaches when elbows are flared out to the sides. Another way to measure this is by having your upper arms at an approximate 45-degree angle from your torso as opposed to keeping arms perpendicular to torso when elbows are flared out to the sides.


Utilizing a spotter can ensure the safety of bench press execution. They can also monitor your technique.

Focus on the concentric portion of the contraction, concentrating on “squeezing” as arms are fully extending as you push the barbell upward.

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.

In order to improve pushing performance through “sticking points”, partial repetition ranges may be implemented to improve full range of motion of the incline bench press. Strategically varying your grip width (narrow, standard and wide grip) and hand positioning (supinated grip, pronated grip) can improve overall bench press performance.

Varying your bench press angles (e.g. flat bench, decline bench) can optimize fiber activation of all portions of the pectoralis major. In addition, strategically incorporating heavy elastic bands and weighted chains in a periodized training program may increase upper body strength and power for experienced lifters and elite athletes.2

It is 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 chest and triceps training to allow muscles to repair.

Lowering the barbell too low should be avoided as it results in excessive shoulder extension and horizontal abduction, which can place great stress on the shoulder joint. Ensure that the upper arms do not pass the level of the torso when lowering the barbell towards your chest. 3

It is very common to observe an individual arching their back in efforts of lifting the weight with more ease. This technique should only be performed by weightlifting professionals and can compromise the safety of lifters.

Lifting heavier weight without a trained spotter. With moderate to heavy weight loads, a trained spotter should monitor the lifter throughout their set for optimal safety. In heavy weight cases, two spotters at each end of the barbell may be appropriate.

If proper technique is not adhered to (e.g. arching of the back, lowering the upper arms past the level of the torso, dropping the weight quickly instead of controlling the descent on the eccentric portion of the lift), the likelihood of injury increases.

If proper technique and recovery are not adhered to, impingement syndrome, rotator cuff injuries, biceps tendonitis/biceps tendinosis and glenoid labrum tears may result. It is best to avoid bench press exercises when addressing impingement syndrome/rotator cuff injury unless advised by a physical therapist.
