We have some highlights for you today from “How To Exercise Without Moving A Muscle -Isometrics For Everyone” by Victor Obeck.

“The word isometric comes from the Greek iso, meaning ‘the same’, and metric, meaning ‘length’. Isometric contraction refers, therefore, to the tightening of a muscle without changing its length.”

“There are some people in the field of physical education who will tell you that if you get enough isotonic exercises, you do not need isometrics. I disagree–and for very good reasons. For one thing, isometrics exercise muscle fibres that would otherwise remain idle. For another, they tone up muscles far more efficiently than do isotonics–they do a better job in less time. And lastly, how many people do you know who have the time to devote to a complete regimen of vigorous exercise? You can run through the whole set of isometric exercises in 90 seconds a day–in your spare time. But a full set of the necessary isotonic exercises may take up to ten times as long–and usually you can’t be doing something else at the same time.”
