According to Healthline, isotonic exercises include those used while weight lifting, circuit training and resistance training. Isotonic exercises are usually done with dumbbells, barbells or resistance bands, but push ups may be substituted when such equipment is not available. The Harvard Medical School states that bench presses or chin ups are examples of isotonic exercises.
According to Healthline, isotonic exercises strengthen muscles and improve joint mobility through training that involves contractions in which tension is the same throughout the range of motion. This muscle training technique involves eccentric movements when the weight is lifted and concentric movements when the weight is returned to starting position.
According to the Harvard Medical School, isotonic exercise is usually the foundation of strength training because it builds muscle strength and endurance without overtaxing the cardiovascular system. Isotonic exercises are those that rhythmically and repetitively use large muscle groups without making the muscles work against heavy resistance. These exercises include walking, bicycling, rowing and other common activities. Regular exercise helps protect the body against heart attack, diabetes, stroke and high blood pressure.
Healthline advises individuals to begin with a warm-up routine and end with a cool-down segment that includes stretches that each last about three to five minutes. According to Healthline, exercise conditions the body, improves health, maintains fitness and helps rehabilitate injured parts of the body. Anyone with pre-existing injuries or chronic pain is advised to consult a physician before engaging in rigorous exercise.
