The bench press is a popular exercise for building strength in the upper body, particularly the chest, shoulders, and arms. It is a compound exercise that targets multiple muscle groups, with the specific muscles worked depending on the variation performed. The bench press can be performed with different angles, hand positions, and equipment, each of which will activate different muscles to varying degrees.

What You'll Learn
Chest muscles
The bench press is a popular exercise for building strength in the chest, arms, and shoulders. It is a compound exercise that targets numerous muscles in the upper body, but the chest muscles are the prime movers and receive the most activation.
The chest muscles that are targeted during a bench press include the pectoralis major and pectoralis minor. The pectoralis major is a large muscle that takes up most of the chest and is responsible for pushing the weight off the chest and back to the starting position. It is also useful for the functionality of the arms. The pectoralis minor, which sits behind the sternum, assists in the rotation of the arms and stabilizes the shoulder. This muscle is activated when the shoulder blades lift off the bench after each repetition.
The incline bench press is a variation that emphasizes the upper chest muscles. Typically, a slight decline of about 30 degrees is enough to elicit this effect. Conversely, the decline bench press emphasizes the lower chest muscles. This variation comes with a higher risk of injury due to the head being tilted downward, which increases blood pressure in the brain.
The bench press can be performed with either a barbell or a pair of dumbbells. Dumbbells allow for greater external rotation of the shoulder, helping to prevent shoulder injuries, and studies have shown that they activate the pectorals more, leading to increased muscle growth. The grip width and bench incline can also be adjusted to target specific muscle groups. For example, a narrower grip will emphasize the triceps and forearms, while wider hand spacing places greater emphasis on the pectorals.

Triceps
The bench press is a compound exercise that targets the muscles in the upper body, including the triceps. The triceps muscle constitutes about 57% of the upper arm muscle mass.
The bench press does work the triceps, but not very well. It only works two of the three muscle heads, and not always optimally. The lateral and medial heads of the triceps activate well during bench presses and grow quite well. However, the long head of the triceps lags behind in growth. This is because it crosses the shoulder joint, interfering with pressing movements.
Some variations of the bench press are better than others for targeting the triceps. For example, a narrower grip bench press will put extra emphasis on the triceps. The close-grip bench press sees the triceps contributing about 37% to the weight lifted, while the chest and shoulder muscles contribute about 63%.
If you are looking to target the long head of the triceps, exercises such as skull crushers or tricep extensions are a better option. Skull crushers are similar to the bench press, but you press the weight up with your triceps instead of your chest. This works the long head of the triceps through a deeper range of motion, stimulating more muscle growth.

Shoulder muscles
The bench press is a popular exercise for building strength in the upper body, including the shoulders. It is a versatile exercise that can be adapted to target specific areas of the body.
The bench press primarily targets the pectoralis major, or chest muscles. The pectoralis minor, located behind the sternum, also helps to stabilise the shoulder.
The anterior deltoids, or front delts, are also activated during the bench press. These muscles are located near the upper chest muscles and are used when reaching the arms out in front of the body or pushing an object away.
The bench press also works the triceps, which are located on the posterior portion of the upper arm. While the biceps are involved in the bench press, they are more effectively trained during back exercises.
The serratus anterior muscles, located below the pectoral muscles on either side of the upper abdominals, are responsible for bringing the shoulder blades forward.
To target the medial and posterior heads of the shoulders, it is necessary to perform additional movements such as lateral raises and rear delt flyes.

Upper body strength
The bench press is a highly effective exercise for building upper body strength. It is a compound exercise that targets numerous muscles in the upper body, including the chest, shoulders, and arms.
The bench press primarily works the pectoralis major, a large muscle that takes up most of the chest and is crucial for arm functionality. The pectoralis minor, located behind the sternum, also plays a significant role in stabilising the shoulder and assisting in arm rotation. These pectoralis muscles work together with the deltoids and triceps to generate the force required to push weights during the bench press.
The deltoids, particularly the anterior deltoids, are important muscles activated during the bench press. They are responsible for reaching the arms forward and pushing objects away from the body. The triceps, specifically the triceps brachii, are also highly active during the bench press, especially at the end of the press to complete the elbow lockout.
Different variations of the bench press can be performed to focus on specific muscle groups. For example, the incline bench press emphasises the upper chest and anterior deltoids, while the decline bench press targets the lower chest. The close grip bench press, with hands closer together on the bar, shifts the focus to the triceps and forearms.
The bench press is a versatile exercise that can be performed with a barbell or dumbbells, and with varying grip widths and bench angles, to target specific upper body muscles and improve overall upper body strength.

Arm muscles
The bench press is a compound exercise that targets multiple muscle groups in the upper body, including the chest, arms, and shoulders. While the pectoralis major and minor muscles of the chest are activated during a bench press, the exercise also engages the arm muscles, including the triceps, biceps, and forearms.
The triceps brachii is a muscle group located on the back of the upper arm between the shoulder and elbow. Its main function is elbow extension, which is critical for "locking out" the elbows during the bench press. The triceps are most crucial at the end of the press to help complete this movement. A narrow grip bench press will put extra emphasis on the triceps and forearms.
The biceps brachii, on the other hand, help to stabilize the upper arms and shoulders during the bench press, especially when using a wider grip. While the bench press does recruit the biceps to some degree, it is recommended to perform exercises that specifically target the biceps, such as bicep curls or chin-ups, for better bicep gains.
Additionally, the single-arm bench press variation involves lifting a single dumbbell with one arm. This unilateral exercise helps ensure that both arms perform the same amount of work, reducing any excessive muscle imbalances. It also allows each arm to work at its full capacity and promotes more even strength development between the right and left arms.
The bench press provides a comprehensive workout for the upper body, targeting multiple muscle groups and improving strength, endurance, and muscle development. By varying the grip width and equipment used, such as barbells or dumbbells, individuals can further focus on specific muscle groups in the arms and upper body.

Frequently asked questions
Bench press is a compound exercise that targets numerous muscles in the upper body, including the chest, shoulders, and arms.
The prime movers during a bench press are the chest muscles, triceps, and the front of the shoulder muscles, or the anterior deltoids.
The pectoralis minor is one of the main stabiliser muscles in the chest and assists in the rotation of the arms around the axis of the body.
Dumbbells allow greater external rotation of the shoulder, helping to prevent shoulder injuries. Studies have also shown that dumbbells activate the pectorals more, leading to increased muscle growth.
Wider hand spacing places greater emphasis on shoulder flexion, while narrower hand spacing utilises more elbow extension. Narrower hand spacing is associated with training the triceps and can be achieved using a close grip bench press.
