Something that keeps me wanting to exercise is acquiring and developing fitness skills. I first really experienced how satisfying it is during my years at a CrossFit gym, where my training built towards achieving certain skills or addressing weaknesses.
While not everyone is like me—some people just want to work out occasionally for general fitness or weight management—few are completely immune to the satisfaction of achieving a physical feat that was once beyond them. I’ve seen it firsthand with the people I train.
