The Biggest Loser Ultimate Workout brings a healthy lifestyle into the family living room as never before, providing new ways to play together and motivate each other through exercise, diet, stat comparisons and light-hearted competition.

As an added bonus, for 24 hours following the May 10 episode, the Pilates Exercises add-on pack will be available free (it's normally 400 MS points...$5) on Xbox LIVE Marketplace.
