Need a little inspiration? Amid earthquakes, hurricanes, the impending cancellation of our final summer vacation, and the thought of slipping back into our skinny jeans, we surely do. So, meet our FITiST of the week. Tiffani worked her butt off to trim, tone, buff and burn to look smokin' in that Jenny Peckam dress at her recent wedding in Mexico. There's nothing like a good goal to get us motivated, and Tiff is a solid example of where ambition and focus can take you. Bring it on.
