The plank (also called a front hold, hover, or abdominal bridge) is an isometric core strength exercise that involves maintaining a difficult position for extended periods of time. The most common plank is the front plank which is held in a push-up position with the body’s weight borne on forearms, elbows, and toes.
Many variations exist such as the side plank and the reverse plank. The plank is commonly practiced in pilates and yoga, and by those training for boxing and other sports.
The plank strengthens the abdominals, back, and shoulders.
A push-up, or in British English a 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.
