Since the advent of the Wii Balance Board, it seems that everyone wants to jump into the ring to get people in shape with video games. Jillian Michaels' Fitness Ultimatum 2010 is the second effort from Collision Studios at making a fitness game for the Wii. This year's edition has smartly decided to ditch events like jumping between logs on a river, opting instead to have the on-screen characters mimic your movements. The developers have created a game that centers entirely on workouts and their associated benefits. The end result is an effort that feels simple, but it has a solid foundation to build on so that the Fitness Ultimatum series can make a dent next year in the genre leaders of Wii Fit and EA Sports Active."
