Description

There are differences between isotonic and isometric exercise, one is that in isotonic exercises or dynamic it involves weights and must be done in specific ways to avoid injury. While isometric or static exercises don't need weights and can be done by any person, as they involve very little movement. What we mean by that is that isotonic exercise are the everyday workouts you do at the gym which involves a range of motion. It involves your muscles contracting – either shortening or lengthening. While isometric exercises are strength exercises where your muscles contract while you hold a still position. For example, when you’re in a gym your most workouts will be isotonic exercises. But If you do yoga, you would do a little more isometric exercises. If you are into calisthenics, most of your workouts will be based around isometric exercise, where you would need to hold positions for little longer. Other than building strength, all have their own advantages. To further explain and give emphasis on their differences these are their advantages: Isometric 

One can attain maximum muscle contraction



Improve bone density



Improve cholesterol level



Improve digestion



Maintain muscle tone and shape



Recovery and rehabilitation

Isotonic 

More range of workouts



Relatively cheaper



More blood is pumped which increases muscular endurance



All major muscle groups can be exercised



Needs fewer repetitions



Build strength on the full range of motion...
