If you think trainers Bob Harper and Jillian Michaels are relentless on NBC's "The Biggest Loser," wait until they're actually inside your living room.
The Wii and Nintendo DS version of "The Biggest Loser," coming this fall, seems to promise everything except someone who will come over and do the workouts for you: Set at "The Biggest Loser" ranch, the game features Harper and Michaels coaching you through workouts and challenges.
Interactive features include using the Wii Balance Board to monitor your movements as you perform more than 60 exercises such as squats, lunges, cardio and -- Harper's favorite -- yoga. There's also diet and fitness advice and recipes. There are multiplayer options and the ability to set goals and pick a four-, eight- or 12-week program to get there. The Wii will go for $39.99 and the DS/DSi version for $29.99.
