The push up may just be the perfect exercise that builds both upper body and core strength if Done properly, it is a compound exercise that uses muscles in the chest, shoulders, triceps, back, abs, and even the legs. A pushup uses your own body weight as resistance, working your upper body and core at the same time. A push-up (or press-up) is a common calisthenics exercise performed in a 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. Push-ups are a basic exercise used in civilian athletic training or physical education and commonly in military physical training. They are also a common form of punishment used in the military, school sport, or in some martial arts disciplines. How To Perform PUSHUP? 1.
