Push-ups are commonly used as a strength building exercise. You perform push-ups by placing yourself in a horizontal position balancing on the hands and toes while facing down, then using the arms to raise and lower yourself. This may also be known as a press-up. Physical education or civilian athletic training will frequently incorporate push-ups into their routine. Push-ups help to train the midsection of the body while strengthening the core.

Benefits of Push-Ups for Certain Parts of the Body

• Scapula. Push-ups move the scapula through a full range of motions while exercises such as bench presses limit the amount of movement the scapula performs. This exercise helps retract and depress the scap muscles to create a stable platform that can be used during other variations of this exercise.
• Serratus anterior. Performing push-ups correctly will allow you to activate the serratus anterior while you are at the top of this motion. This muscle is usually inactive during other activities, but those that regularly perform motions over their head will need this muscle to be in good shape to prevent injury. If the serratus anterior is not performing properly, it may cause your scapula to wing which may jeopardize your stability and ability to rotate your arm upwards. In order to exercise this muscle during push-ups, make sure you are pushing yourself up off the floor as much as possible, perhaps even until the arms lock and do not let the torso sag. This can also help you build back strength that can limit your risk of back pain later.
• Torso stability. Push-ups help you develop stability that will help you avoid lower back pain or injuries to this area. Push-ups allow you to activate your obliques more effectively than other exercises, allowing you to build strength within the torso and core musculature. This will help you develop the strength necessary to take pressure off the lower back.
• Shoulder. Push-ups help you stabilize your shoulder girdle. Performing blast strap or medicine ball push-ups increases this benefit. Push-ups help you activate the prime movers in the shoulders so you can increase strength and function in these areas.
