I figured it out! I've been fretting over my reward for reaching my 25-pound goal by the end of the 12-week BetterU program.
I'm going to get a Wii AND the Wii Fitness game AND the new Wii Active! I've wanted the Wii and Wii Fitness for months but have not been willing to spend the money (being laid off is NO fun!). Well, I'm going to get the whole shebang when I reach my 12-week goal! That's a reward that will help me make it to my final goal. Win-win...wiiiiiiii!
