What is Isotonic Exercise?

An Isotonic exercise is a form of weight training. It is performed using free weights to condition a muscle group and build them stronger. Isotonic exercises focus on overall fitness and are quite common among those who are looking to lose weight, tone their body, increase muscle power and build larger muscles. Dumbbell curls, bench press are some of the classic examples of isotonic exercises.

It is your everyday workouts performed at the gym using weights at variable speeds. The method basically focuses on the isotonic contraction of muscles during the workout. Using a static weight, tension is created in muscle throughout the motion. This impacts the muscle and eventually, the muscle cells enlarge and the amount of weight it can pull also increases. In simple words, it is a form of muscular exercise performed to increase muscle strength and endurance.

The term Isotonic is derived from Greek words: ‘Iso’ meaning equal and ‘Tonos’ meaning maintaining equal tone.

Types of Isotonic Exercise

Isotonic exercises are of two types, based on contraction of the muscles: concentric and eccentric. The concentric contraction occurs when the muscle shortens, while eccentric contraction occurs when the muscle lengthens. Lifting weights is a typical example of concentric contraction and putting them down is an example of eccentric contraction. In simple words, concentric contraction takes place when the muscle is working actively and manipulating the resistance. As for eccentric it is usually when the muscle is working passively.

Researchers and scientists suggest a combination of concentric and eccentric movement found in Isotonic exercise, when performed regularly is quite beneficial. Weight lifting, elliptical training, climbing stairs, push-ups, and squats are examples of a perfect combination of concentric and eccentric movements in an isotonic workout.

Meanwhile, isometric exercise involves exerting resistance, but the muscle remains unmoved. The word isometric comes from the Greek words ‘iso’ meaning equal and ‘metron’ meaning measure. It means maintaining the same measure or length. It is said that most of the gym workouts consist of isotonic movements and the yoga workout is more about isometric movements.
