Isometrics is the term used to describe exercises that involve the static contraction of muscles. This type of exercise is popular for building strength and improving flexibility without putting excessive strain on the joints. Some synonyms for isometrics include tension exercises, static holds, and resistance training. Isometrics can also be called static resistance exercise or isometric contraction. The focus of isometrics is to maintain a static position rather than moving through a range of motion. This type of exercise is versatile and can be done using body weight or equipment such as resistance bands. Incorporating isometrics into your fitness routine can be a great way to challenge your muscles and improve overall strength and stability.
