What is isometric exercise?

“Isometric” is the Latin word literally meaning “equal measurement.” As this relates to exercise, isometric exercise is the type of muscle contraction in which the muscle is tensed and working, but not actively shortening or lengthening (with no joint movement).

Comparatively, concentric contractions are the type of contractions in which a muscle, or muscle group, is shortening (such as the abdominal muscles during a sit up) and eccentric contractions are the type of contractions in which a muscle, or muscle group, is lengthening (such as in the relaxation of the sit up motion).

While all forms of exercise provide benefits, isometric exercise is unique in the benefits it provides. Isometric exercise is also ideal for people who suffer from chronic joint pain.
