Everyone wants to look good and feel healthy in present times and can go to any extent to achieve it. What if I offer you a routine involving a decent work-out for a short span ensuring absolute achievement of your health goals? Where this might particularly pertain to women, it certainly hails good news for men because strengthening muscles through isotonic exercises is the in thing today and people are loving it. Let’s find out why!

Isotonic way of putting the muscles to work has caught great popularity off late. It primarily involves a mechanism in which the size of the muscles changes but the tension levied on them remains unchanged. Some of its examples include lifting an object off a desk, walking or running. These activities involve isotonic contractions in which the magnitude of pressure put on the muscles does not undergo any apparent change. These isotonic movements are also called as Auxotonic contractions.

There are mainly of two types:

• Concentric: In this the tension in the muscles is raised to meet the resistance offered. It is then continued to remains the same even as the muscle shortens.
• Eccentric: In this the muscle size increases because the resistance offered is greater than the force produced by the muscle.

As every muscle moves along its full range, isotonic contractions create tension with full effort at the beginning as well as the end of each exercise. Isotonic exercises are carried out using dumbbells or fixed equipment like barbells. The difference between both mainly lies in the magnitude of resistance used in both.

Both forms of isotonic contractions are of great advantage in strengthening the muscles and the fact that they are highly inexpensive makes them more popular among people now a days. However another reason that makes them so high in demand is that they help put all muscles in use by employing a wide range of exercises.
