I haven't set up rewards for myself for this time, only because I am very motivated by the changes in my body and hopefully on the scale.
Last time I rewarded myself with each ten pounds gone. One was a bike shirt, one was a pair of spin shoes. Oops, I didn't get much past that. I never rewarded myself with food or a "cheat" day because it felt silly to do that and go against my own principles.
I have to wear a cocktail dress in April for a black tie optional event that falls on my birthday weekend. I think getting my sexy back will be a good reward. And the red dress and killer shoes.
