What Is Toning? When most people say that they want to “tone up,” what they usually mean is that they want to become leaner. Basically, they want to lose fat, and add a little muscle definition—but not so much muscle mass that they look like a bodybuilder (much more on that later).
In the fitness world, there is no real definition for toning that is greatly recognized. Rather, toning is a term used to describe the end goal, which usually results from a combination of basic weight-lifting and fat-burning.
Toning, on the other hand, typically refers to aerobics instructors and Hollywood starlets who have lower amounts of body fat and some visible muscle, but not huge muscles. So now that we have our definitions straight, let’s move on to facts and the fallacies about toning up and bulking up.
