Push-ups are a versatile exercise that targets multiple muscle groups, making them a valuable addition to any workout routine. While they are particularly effective for strengthening the upper body, including the chest, triceps, and shoulders, they also engage the core and lower back, contributing to improved functional fitness and overall strength. With various modifications available, push-ups can be tailored to different fitness levels, from beginners to advanced, making them accessible to a wide range of individuals.

What You'll Learn
Triceps
Push-ups are a great way to target and strengthen your triceps. The tricep muscle is made up of three distinct heads, the anterior, lateral, and posterior heads, all of which are active during a push-up.
The anterior head is targeted the most during a standard push-up due to its location on the front of the shoulder joint. This head originates from the frontal part of the clavicle bone and inserts onto the outer part of the upper arm. During the upward phase of the push-up, the anterior deltoids help bring the arms inward towards the chest.
The lateral head of the tricep is the outermost part of the muscle, giving your arms a sharp, defined look when flexed. This head is responsible for elbow extension, helping to straighten your arm during the upward movement of a push-up. To emphasize this head, keep your elbows tucked in and maintain proper form throughout the downward movement.
The medial head, or the middle head, of the tricep runs along the back of your arm and is active during all push-up variations. It is the stabilizer muscle that keeps your movements controlled.
To ensure your triceps are engaged during a push-up, focus on proper form. Keep your elbows tucked in and your core muscles engaged. Avoid letting your chest muscles take over the movement.
If you want to target your triceps even more, try a modified tiger push-up or a diamond push-up. These variations increase tension on your triceps while reducing the load on your chest.

Pectoralis muscles
The pectoralis major and minor are the prime mover muscles during a push-up. The pectoralis major is the largest of the chest muscles, and it serves as the agonist during a push-up. It is thick and fan-shaped, found just under the breast tissue. It consists of two heads: the clavicular head, which originates from the medial part of the clavicle, and the sternocostal head, which originates from the sternum and upper ribs. During a push-up, this muscle controls the descent of the torso towards the floor and pushes the body back up to the starting position.
The pectoralis minor, on the other hand, is a smaller, triangle-shaped muscle that lies under the pectoralis major. It originates from the front third to fifth ribs. During a push-up, the pectoralis minor keeps the scapulae, or shoulder blades, in position, allowing for correct posture of the shoulders and upper back.
While the standard push-up targets the pectoralis muscles, there are variations that can increase the intensity and target the upper pecs, or pectoralis, more. For example, decline push-ups, where the feet are elevated, create more tension for the chest muscles, making the movement harder. Additionally, narrow palmar width during push-ups increases the muscle activity of the pectoralis major and minor.
The push-up is a versatile exercise that can be modified to challenge the pectoralis muscles in different ways. By varying hand spacing, incorporating pauses, or focusing on negative contractions, individuals can maximize the activation of the pectoralis muscles and stimulate muscle growth in the chest.

Deltoids
Push-ups are a versatile exercise that can be adapted to target different muscle groups. While they do not work the rear delts, push-ups do target the anterior deltoids, which are the front delts.
The anterior deltoids are synergists, or helper muscles, in a push-up. They assist with elbow extension and shoulder flexion. During the upward phase of the push-up, the anterior delts help adduct the shoulder joint, bringing the arms inward towards the chest. They also help to stabilise the shoulders during the downward phase.
The deltoids are targeted more during some variations of the push-up. For example, the standard push-up targets the chest muscles, but the incline push-up, performed with the hands positioned higher than the feet, targets the deltoids more. Push-ups with the feet elevated also produced more force than other variations, according to a study by Ebben et al. (2011), which may increase the intensity for the deltoids.
The posterior deltoids, or rear delts, are not targeted by push-ups. These are the muscles that sit on the back of the shoulders and help to stabilise them. People with sedentary lifestyles tend to have poor posture, which causes the posterior chain muscles, like the rear delts, to become weaker than the anterior muscles. To strengthen the rear delts, pulling exercises like rows, pull-ups, and face pulls are recommended.

Abdominal muscles
Push-ups are a compound bodyweight exercise that targets several muscles in the upper body. While they are predominantly known for working the muscles of the chest, shoulders, and arms, they also engage the abdominal muscles.
The abdominal muscles, or abs, are a group of five main muscles: the rectus abdominis, transversus abdominis, internal and external obliques, and the pyramidalis. These muscles are intrinsic to stabilising the torso during a push-up, helping to keep the body parallel to the floor. The rectus abdominis forms the front sheath of the abs and acts as a stabiliser, while the transversus abdominis is a deep core muscle that also helps with stabilisation. The internal and external obliques are located at the sides of the waist and assist in maintaining balance.
To increase the activation of the abdominal muscles during a push-up, you can modify the exercise by placing your feet on a stability ball, performing one-leg push-ups, or trying push-ups with shoulder taps. These variations not only challenge your balance but also require greater engagement of the abdominal muscles for stability and control. Additionally, performing push-ups with a controlled tempo, by slowing down the lowering and pressing phases, can help increase the time under tension for the abdominal muscles, enhancing their development.
While push-ups do activate the abdominal muscles, they may not be sufficient on their own to create a highly defined midsection. Incorporating other abdominal-specific exercises, such as plank holds, crunches, and torso twists, in combination with a consistent push-up routine, can help to develop a more toned and defined abdomen.

Shoulder joints
Push-ups are a versatile exercise that can target several muscles in the shoulder joints, depending on the variation performed.
The shoulder joint is a complex structure comprising various muscles, tendons, and bones. The primary muscles in the shoulder joint include the deltoids, which have three heads: anterior, lateral, and posterior. During a standard push-up, the anterior deltoids are targeted the most as they help adduct the shoulder joint, bringing the arms inward towards the chest during the upward phase. Additionally, the anterior deltoids contribute to shoulder stability during the downward phase of the push-up.
The rotator cuff muscles, another crucial component of the shoulder joint, play a vital role in keeping the head of the humerus bone firmly within the glenohumeral joint. Push-ups, particularly those performed with proper form, can strengthen these muscles and improve shoulder stability.
Furthermore, the upper trapezius muscles assist in the upward rotation of the scapulae, contributing to the overall stability of the shoulder joint during push-ups.
For individuals with shoulder dysfunctions or pathologies, a modified version of the push-up, known as the "push-up plus," is recommended. This variation involves protracting the scapula while maintaining the same starting position as a traditional push-up. By avoiding full lowering to the floor, this exercise helps build shoulder strength while reducing the load on the muscles.
Additionally, wall push-ups are suitable for beginners or those with shoulder injuries. This variation involves standing in front of a wall and performing a push-up against it, which helps build shoulder strength while placing less stress on the joints.
In summary, push-ups and their variations can effectively target and strengthen the muscles surrounding the shoulder joints, including the deltoids, rotator cuff, and upper trapezius. These exercises improve shoulder stability, range of motion, and overall functional fitness.
