What comes to mind when we hear the word “exercise?” The definition of exercise varies from person to person. Here are three examples. Colleen views exercise as a means to lose weight and shape her body. She only exercises when she is dieting, and then she pushes her body to its limit. She is sore from grueling workouts, cranky because she is not fueling her body sufficiently to give her energy, and often injured from the wear-and-tear on her body. To her, exercise is exhausting, taxing, and depleting. Roberto views exercise as a way to manage his appearance. He runs sixty miles a week, even when injured, and lifts weights for several hours every day, afraid that he will lose his lean body mass. Exercise has become compulsory for Roberto, something he feels he “has to do.” If he doesn’t maintain his routine, he thinks of himself as a “failure” and feels guilt and anxiety. Jasmine walks, hikes, dances, or engages in yoga nearly every day, and she determines which activity to do based on her interest.
