3. Write up a contract. Make a solid commitment to yourself by drafting up a contract. You can add all the details about your fitness resolutions in a simple document, then sign and date it. Place the contract in a visible area like your refrigerator or near your desk so you know what you're working towards on those really tough days.

4. Work out at the same time. Schedule exercise into your calendar just like you would schedule an important appointment. Make sure you're making your "appointment" each day so that you can get into the fitness habit and continue on with your commitment to get fit! Just make sure you're changing up the exercise routine and keeping track of your workouts to stay motivated.

For example, if you commit to working out at the gym four times this week, allow yourself to go on a weekend shopping trip or take that cooking class you've always wanted to take. You'll be more motivated to stick with the exercises when there's an extrinsic goal waiting at the end of the week; plus, you'll benefit from the natural side effects of your workout!
