In brief: Motion-No Motion
Isometric exercise is where muscle force is exerted without changing the length of the muscle fibers.
This is accomplished by pushing or pulling against an immovable object or by simultaneously contracting opposing muscles, such as by pressing the hands together. There is no joint movement. Isotonic occurs when a contracting muscle shortens against a constant load, as when lifting a weight.
