I wanted some exercises I could do without equipment. Moreover, I had read that isometric exercises were, in many ways, superior to isotonic, such as weight lifting.
I know that power yoga, a combination of isometric and isotonic, is a wonderful, dynamic workout. But, I wanted something totally isometric and powerful.
What is the secret of the isometric contraction and isometric exercises in general.
According to the author, "Now, instead of performing biceps curls with weights, what happens when you work your muscles against each other? Imagine you place your hands together palm-to-palm in front of your chest and you start squeezing as hard as you can. Your brain is getting the message that it is trying to move your right arm leftward and your left arm rightward. In order to do this it needs to contract muscles in both arms. It starts to do this but because there is no movement, no contraction occurs. How does your brain respond? It keeps recruiting more and more muscle fibers together in an attempt to contract the muscles and move the arms. It has no idea that this is a futile exercise as the arms are acting against themselves! In a way with an isometric contraction you are tricking your brain into using ALL of the available muscle fibers at the same time. This is why it is possible to exhaust ALL of the muscle fibers in 7 to 12 seconds." That, he says, is the secret to isometric exercising.
To illustrate the power of isometrics the author tells the story of Alexander Zass. He writes, "A world famous strongman at the beginning of the last century, he was known by his stage name "The Mighty Samson". He is also considered by many to be the father of isometric exercises. This is his story.
Young Alexander was born in Poland but raised in Russia. When he was a boy his grandfather took him to the circus. Of all the sights he saw there, it was the circus strongmen that impressed him the most. He vowed to become as strong as they were and join the circus himself one day. He started training immediately, doing such activities as climbing trees and lifting barbells and dumbbells.
It wasn't long before he was strong enough to join a circus. Once there he learned even more from the strongmen he worked with. He built his physique up and he was widely known for his great strength. During World War I, however, Alexander Zass was captured and imprisoned by the Austrians.
Confined to a cell and bound by shackles, Zass became despondent. How could he train when he could barely move? He feared that without exercise he would rapidly lose the incredible strength that he had worked so hard to acquire.
Out of sheer frustration he began straining against the shackles that bound him and the prison bars that confined him. Without knowing it he began exercising using isometric principles.
Much to his surprise he found that this method of training allowed him to become stronger than ever before!
How strong did he get? So strong that when the opportunity presented itself he was able to bend and break the shackles that bound him BY HAND. Next he ripped out the prison bars, bent one of them into a J hook for scaling the wall, and was able to make his escape!
After the War, Alexander Zass toured Europe performing amazing feats of strength as the "Mighty Samson". He was known for bending bars, breaking chains with his chest, lifting 500 pound girders with his teeth and carrying small horses. The only training method he used was isometrics - he never lifted weights. Later he published a training book of isometric exercises that sold well throughout Europe."
Actually, as the story says, Zass did lift weights at least in the beginning of his career. But apparently he did not after his stint in prison.
But, the important thing is this story illustrates the real power of isometrics. I might add that the late Bruce Lee is said to have used isometrics to a very large extent, as do most martial artists.
The author has a FAQ in the book. He takes the time to answer lots of questions. My one and only concern was that I was not convinced he is truly qualified to write this book. He has no credentials that I can discover. On the other hand, he seems to have done his research.
Finally, he tells us that if we follow the program for a month we can expect the following:
"Your entire body will be stronger, firmer and more defined. You'll have more endurance and mentally you'll be more focused and alert than ever before. You'll feel more alive and your confidence will soar as well."
I rather think he may be right. For the most part, when done correctly, isometric exercises are powerful and safe. He tells you exactly how to do each exercise and offers pictures.
If you're looking for a good book on isometrics, this is a good one. I must say, however, the part of isometric exercises only takes up about one-half the book. The rest is bonus material --- useful but not related to the subject. At least this is true in the Kindle version, which I have.
Having said that, not much more is needed to be said than what he presents. He covers everything.
Highly recommended.
