Isometric exercise is a type of strength training that involves the tightening (contraction) of a specific muscle or group of muscles without any visible movement in the angle of the joint
. During isometric exercises, the muscle doesn't noticeably change length, and the contraction strength may be varied
. This form of exercise is designed to hold the body in a specific position for a set period of time, which can help build muscular strength and endurance
. Isometric exercises are ideal for low-impact training, require limited space, and may aid in the recovery from certain injuries
. They are also recommended for people who have or have had damaged muscles, as isometrics can help rehabilitate injuries and reduce recovery time
