The body parts that benefit the most by a regular routine of push-ups include the chest, shoulders, forearms and wrist area. Push-ups also help in developing a proper posture and a good torso.
The primary reason behind push-ups gaining such popularity is the fact that it does not require any exercise equipment! Push-ups target six important muscles in the body - the pectoralis, triceps, deltoid, serratus anterior, abdominal and coracobrachialis.
Muscles Targeted By Push-ups
This muscle lies in the chest of the human body. The pectoralis major makes up most of the chest area in the male body, whereas in the female body it lies just under the breast. Under the pectoralis major lies the pectoralis minor - a thin triangular muscle. It is an adductor muscle which facilitates the upward lift and downward push movements in push-ups.
The deltoid is a major shoulder-joint which works prominently during the upward movement of the push-up. Although weak as a set, the deltoid muscles are needed for the shoulder's motion to be proper. Well-defined deltoid muscles are the reason behind rounded, broad shoulders that bodybuilders usually have.
The triceps lie at the back of the upper arm. Their primary function is to extend the arm outward. Triceps make up about 65% of the mass in the upper arm and are the most exerted muscle during push-ups. The intensity of strain on the triceps will depend on the type of push-ups one opts for.
The serratus anterior muscle is located at the back of the chest, just under the armpit. If while performing push-ups, the scapula has a winged look, it means that the serratus muscle is weak or virtually inactive. A strong serratus suctions the scapula during the movement, eliminating the winged look.
The serratus anterior is usually an inactive muscle, but performing push-ups cause these muscles to activate. A regular push-up routine will strengthen this muscle further. A strong serratus anterior muscle helps in smooth, forward movement of the shoulder blade during push-ups or other similar exercises.
The coracobrachialis is a narrow muscle that runs from the shoulder blade to the biceps. It pulls the upper arm against the body during push-ups. A well-formed and worked coracobrachialis contributes in a big way while developing upper body strength.
Abdominal muscles contract during push-ups to hold the body above the ground, while keeping the legs and the torso balanced and straight.
Variations of Push-ups
While normal push-ups work the shoulders with a little attention to other muscles, this variation impacts the chest and triceps more.
How to Do Push-ups
- Now slowly exhale and push your body up to the starting position.
- Repeat this exercise after a brief pause of about 2 seconds.
It is important to note that if you perform different variations of the exercise, the focus will shift to different muscle groups. Before you try any of the variations, it is recommended that you talk to your trainer so that you do not injure yourself.
