Jillian Michaels is a tough cookie when it comes to training, and I love her hardcore attitude. The Biggest Loser trainer teamed up with Nintendo to create her workout for Wii Fit called Jillian Michaels' Fitness Ultimatum 2009 ($37), and the final product looks like a fun way to get fit.
She visited ABC News to discuss the game and explained that she "got fat" as a kid playing video games, and hopes the Fitness Ultimatum will be an effective solution for combating childhood obesity. She's targeting kids by making the game fun and interactive, complete with cool graphics, but it's something the whole family can use. Jillian says eventually you can burn 300 to 400 calories an hour doing things like kickboxing, running, and squats.
