Push ups with variations... 

A push-up is a common calisthenics exercise beginning from the prone position. By raising and lowering the body using the arms, push-ups exercise the pectoral muscles, triceps, and anterior deltoids, with ancillary benefits to the rest of the deltoids, serratus anterior, coracobrachialis and the midsection as a whole. 
Pushups are an exercise in which a person, keeping a prone position, with the hands palms down under the shoulders, the balls of the feet on the ground, and the back straight, pushes the body up and lets it down by an alternate straightening and bending of the arms[1].

Traditional pushups are beneficial for building upper body strength. They work the triceps, pectoral muscles, and shoulders. Using proper form, they can also strengthen the lower back and core by engaging (pulling in) the abdominal muscles.Pushups are a fast and effective exercise for building strength. They can be done from virtually anywhere and don’t require any equipment[2].

Muscles Involved

￼

The agonist (prime mover muscle): pectoralis major. As you lower yourself toward the floor, the pecs lengthen and control the speed of your descent. As you push back up again, they shorten. The lowering and lengthening phase of the exercise is called an eccentric contraction while the lifting and shortening phase is called a concentric contraction.

Antagonists (the muscle which opposes the agonist): the main ones are the middle fibers of the trapezius muscle, the posterior deltoids and the rhomboids (all on the opposite side of the torso in relation to your pecs).

Synergists (helper muscles): Although not the target muscle of the exercise, these muscles are important as they assist the agonist. The main synergists in the pushup are the triceps and the anterior deltoids. They assist with elbow extension and shoulder flexion, respectively.

Fixators: rotator cuff (keep the head of your humerus firmly located within the glenohumeral joint), the upper traps help with upward rotation of the scapulae, and core muscles (hold the spine straight). Other fixators include latissimus dorsi muscles (aid in shoulder stability) and quadriceps, which work to keep your legs straight and rigid[3].

Push-ups offer many health benefits, including:
Burning calories.
Protecting your shoulders and lower back from injuries.
Improving your balance and posture.
Improving your flexibility.
Improving your performance in sports and athletic activities.
