Definitions for "isometric exercise"
A system of exercise to strengthen specific muscles of the body by pushing parts of the body (such as the two hands) strongly against each other, or against a fixed object, so that the muscles are strongly stressed, but are stretched only a little. It is claimed to produce strength in the muscles thus exercised. Also called isometrics.
Muscular contraction where muscle maintains a constant length and joints do not move. These exercises are usually performed against a wall or other immovable object.
tensing of a muscle against an immovable outer resistance, which does not change muscle length or produce joint motion
