Isometrics are a type of strength training that is usually performed in a static position in which the muscles are worked against an immovable object. Isometric exercise and training were used thousands of years ago. The Greeks classified this type of training as soft exercise. Yoga and martial arts incorporated the use of static holds which, in modern days, are considered to be a part of isometrics. The techniques and training associated with isometrics became very popular in the early days of bodybuilding. Some of the more famous bodybuilders that used isometrics in their training regimen were Eugen Sandow, Charles Atlas, Bernarr McFadden and Alexander Zass (better known as the amazing Samson).

Alexander Zass was a Russian prisoner of war that was held in Austrian prison camp during the first World War. During his imprisonment, he had no access to any physical activity and feared he would lose his strength. He would pull and push his prison bars and shackled chains that he wore all of the time. To his amazement, Alexander grew in strength and developed his techniques with isometrics. This is when Alexander Zass developed his first use of isometrics. As time passed, Alexander increase his strength to the point where he was able to break his chains are bend his cell bars to escape from prison. Later, Alexander Zass was known as “The Father of Isometrics.”

The popularity of isometrics has declined over time for various reasons. However, the pioneers of isometrics have left their mark and you can still find aspects of its use in today’s physical and weight training programs. Isometric exercises are still great techniques to use in conjunction with traditional exercises today.
