Take the stairs instead of the elevator at work everyday and it will help you lose as much as 10 pounds a year. Taking the extra 5 minutes out of your day to take the stairs means you will not have to force yourself to exercise later when you will be easily distracted.
A good way to help you lose weight is to share your progress and results with your friends and family. Having that external motivation will push you to strive even harder to continue with your fitness goals. It's also nice to be able to inspire someone else to lose weight.
