You’ve seen her kick butt as a personal trainer on TV’s “The Biggest Loser,” now see what she can do for you! She’s designed this game to help you get fit, and stay fit, using a boot-camp Hell Week style, set on a rugged tropical island. I love it… it’s such a great workout, and I really liked the built-in calendar to track my progress!
