Make Money a Factor
Allow money to be your motivator in moving your tush off the couch. When you join a gym or sign up for fitness classes, you sign a contract for the most part. If you are paying for something like this every month, you will get moving and show up. You will be more likely to stick to the commitment when money is leaving your account every month as no one wants to give money away. But it is more than this, by joining a gym under a contract you are forcing to make a commitment to yourself as well.
