Try viewing fitness as a gift to yourself. Working out is not punishment for some make believe personal shortcoming. It is a healthy habit that will improve your mental outlook, your self esteem and your physical well being.
Make healthy choices - like eating right and exercising - because they make you feel better about yourself and truly improve your health, not because you are required to do so by your guilt, your doctor or your scale.
So, does your schedule today include an exercise session? Yes? Aren't you lucky!
