Workouts using the isometric method include contracting (or tightening) a single muscle or a group of muscles. Workouts that focus only on isometric contractions do not result in any perceptible lengthening of the muscle. As a result of the injury, the affected joint is completely immobile. Isometric exercises may help keep your strength at a steady level. They are also capable of fortifying themselves, but not very successfully. In addition to this, they are portable and may be used in almost any environment. The plank position and the leg lift are two excellent examples. Workouts that are classified as isometric are ones in which your muscles contract while remaining in a stationary position.
