As you travel along your fitness journey, you shouldn't wait to reward yourself until you reach your final weight loss goal. You should reward yourself for the little achievements along the way. Pat yourself on the back every few pounds you're down or for every minute you shave off of your mile.
One of the first rewards you should give yourself is some new fitness gear. Treat yourself to a new pair of running shorts or a new yoga matt. This type of reward can help motivate you to continue your active ways.
