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.

The title “Panaerobic Walking” is a bit misleading. After all, “HeavyHands” was by Dr. Schwartz’ definition “panaerobic”, i.e. seeking to mobilize as much muscle tissue as possible to process oxygen by using all four limbs simultaneously in a series of “inefficient” motions (i.e. motions unnecessary to accomplish the basic tasks of walking, jogging or running).

Still, the term “Panaerobic Walking” or “Strength Endurance Walking” may be useful to describe an adaptation of “Heavyhands” or “Panaerobics” some users (like the curator of this blog) enjoy using. Here’s the blog curator’s personal experience:


schwartzvidToday, “High Intensity Interval Training”  (abbreviated “HIIT”) is the “rage”.  Some claim it even burns 9 times more fat than “steady state cardio”! (see below for the misquoted research!)

The common line is… “Stop working out so long! Work out hard and intense using intervals!”

As a result, people who yesterday were blobs of blubber sitting on the couch are now told to be in the gym doing “high intensity interval training” with no preparation or foundation whatsoever!

One recent article even promised people they could get fit with a “10 Minute workout“. Unfortunately the research article quoted in support of that contention was mis-interpreted! The scientist behind the study contended sedentary people could greatly improve their overall fitness with 10 minute workouts – if they had 15 of those 10 minute workouts per week! OOPS! Slight oversight there, eh? A recommendation of 150 minutes per week is a bit different than 30 minutes a week isn’t it?  (more…)

ISO1 (1) It’s true! You can get started in IsoTonoMetrics in ONE STEP! Here’s how…

(To be honest, I’m assuming you already know how to WALK!

If you don’t already know how to walk, you’ll need two steps!)


plslogo A previous post started defining panaerobics. Here is some more in the way of definition from Dr. Schwartz’s Panaerobics website:

This was in response to the question: “How does ISO generate such enormous strength and aerobic workloads?”

The answer given below. Another definition of panaerobics is in bold, but the whole passage is worth considering:



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.


What exactly are “Isotonometrics”?

Basically they are Dr.Schwartz’ combination of “Isotonics” and “Isometrics” in one movement… a “moving isometric” or what some call “isomotion” today…

The “isometric resistance” was produced by a variety of “handclasps” where one arm resists the other through pushing or pulling in varying directions. Unlike traditional isometrics or “dynamic tension”, the arm movements were incorporated into larger body movements to activate as much muscle simultaneously as possible.  Body twists, knee dips, waist bends, lunges, etc where mixed with hand resistance moves.

It was not only the arms that were involved …
