Isometrics, << `y` suh MEHT rihks, >> is a method of exercise that involves little or no visible movement. To perform isometrics, people push or pull against an immovable object, such as a wall, a heavy desk, or another part of their body. This pushing or pulling activity contracts (tightens and shortens) the muscles. If the muscle contraction moves the object, the exercise is called isotonic, or dynamic.
Isometrics, if practiced for a few minutes daily, will rapidly strengthen the muscles as well as maintain muscle tone. Most isometric exercises require no special equipment.
