Performing push-ups works a variety of muscles in your upper body, including specific muscles within your abdomen, chest, shoulders and upper arms. You can vary your technique by placing your hands at different widths to emphasize one area over another.
A push-up not only helps you to get a stronger upper body, but also a stronger midsection. It incorporates the stabilization muscles of your core, combining an upper-body pushing movement with a plank. It is, in fact, one of the best and most basic exercises for your midsection.ush-ups are traditionally used to work your chest muscles, but by altering your technique slightly, you can work different muscle groups, including your abs.
