If you’re familiar with Charles Atlas or other self-resistance exercise systems (sometimes called “Dynamic Self Resistance” or “DSR”) Dr. Schwartz’ IsoTonoMetrics may still seem baffling to you. Don’t worry, many people are similarly baffled at first!

Look at it this way, if you’re familiar with a variety of self-resistance exercises already, you’re half way there!

The difference between a classic dynamic self-resistance exercise and an “IsoTonoMetric” is that in addition to the basic self-resistance movement other movements are added to

A. Activate all four limbs
B. Involve as much muscle as possible
C. To build strength and endurance simultaneously

Ok so let’s get more specific and turn a classic dynamic self-resistance exercise into an “IsoTonoMetric”!

In a recent post the way in which Leonard Schwartz’ “IsoTonoMetrics” related to Charles Atlas and Dynamic Tension was mentioned.

Since then, some new information has come to light from Dr. Schwartz’ “Fitness Method” patent that is worth sharing on this topic, especially if people want to understand the inner dynamics of Schwartz’ “IsoTonoMetrics” and practice it for themselves.

Remember that in Schwartz’ IsoTonoMetrics, the hands are clasped or otherwise pushing together or pulling apart in various ranges of motion to activate different upper body muscles.

Bends, knee dips, torso twists, steps, head and neck rotations, various dance like moves, lunges, posture changes, body positions and toe raises are used to create a “whole body” aerobic exercise.



Isotonometric Handclasps

In a previous post on Isotonometrics, the question was asked: “So was this “isometrics”? Or “dynamic tension”? Or something else? That will be explored in a future article!” This is that article.

Dr. Schwartz’s extant writings interact from time to time with the systems advocated by other fitness experts who are mentioned by name, like Charles Atlas.  He is always courteous but clear about how his viewpoint differs and what advantages he believes it to have.

So how did Leonard Schwartz see his work in relationship to Charles Atlas’ “dynamic tension” and “isometrics’? The answer is found in his patent filing on “Fitness Method” with some observations drawn from the Charles Atlas course itself.
