Isometric Exercise

Isometrics is nothing new in fact; the military in many countries have used isometrics as a fast and simple method to strengthen the core muscles in their fighting forces. Schools have used isometrics as a form of exercise in their physical education requirements. The name isometrics is formed from two Latin roots meaning “equal length”. You will understand the meaning better when we get into the actual exercise descriptions.

Mechanics of Isometric Exercise

There are many ways to perform isometrics. Once you have a more complete understanding of the exercise you can create your own custom exercise routine and even make the experience more fun for you. So let’s quickly run through the few terms you need to know about certain muscle groups in the body.

Benefits of Isometric Exercise

Ok, now that we have the basics of the mechanics in the body that isometrics deals with, we can now move on to the further benefit of isometrics.

Examples of Isometric Exercises

Let’s cover first what a set means in case you are not familiar. A set means you have completed one repetition of the exercise a certain number of times. So when a set of 10 repetitions is asked for then this is what a set means. Ok now that we have that down, let’s get sweating.

Strength Exercises

  6. Now slowly tilt head down so chin is as close to the chest as possible. If you can touch your chin to chest that is great only make sure you don’t hyper-extend it.

Warning: Never tilt your head to the back because it puts a ten pound pressure on the upper spine. This can cause injury and therefore be counterproductive to the exercise.

Disadvantages of Isometric Exercises

For the most part if you are in good health with no major issues such as high blood pressure or cardiac issues, you can do isometrics safely and reap the benefits. Isometrics is as safe as any other exercise with one minor concern. You should seek a physician’s approval prior to beginning any exercise regimen.

However, when you have high blood pressure you should do so especially. This is because isometrics can cause a spike in blood pressure and affect the heart rate for a short period of time that may, in rare cases prove a bit dangerous to some.
