Schedule exercise with a friend or a group beforehand. You then become socially obligated to show up. Exercise in a group such as a CrossFit class. If you waver, the group will keep you going. Sign a commitment contract with an organization like StickK.com that sends money to an organization you dislike if you don’t exercise (a stick) or to one you like if you do (a carrot). Sign up (and pay) for a race or some other event that requires you to train. Post your exercise online so others see what you are (or are not) doing.
