* Subscribe to a fitness magazine or online fitness newsletter. New tips and exercises can be inspirational and alleviate boredom.
* Create a competition with co-workers or friends. For example, the team whose members exercise for 30 minutes, three times each week for three months wins a prize. You decide what the prize is.
* Change into your workout clothes. Sometimes, it's just a matter of getting dressed that causes the biggest barrier. Take your changing clothes with you to the office and keep an extra pair in the locker (n case the office has its own gym), so that there is no question of you forgetting clothes or giving yourself an excuse.
* Erase the concept that if you can't do at least 30 minutes of exercise you're wasting your time. Exercise burns calories, increases energy, and improves your health - even in small doses.
* Try a new sport or class. Adding variety, a group support and competition can increase your likelihood of exercising.
