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”!
