This game kicks my butt every time and its fun! I should add; though, that it doesn't register sometimes, mostly when you are doing steps. It will tell you to step forward or backwards, but it makes you miss a lot because it doesn't recognize when you step forwards or backwards a lot of the time. You can use your arms to trick the game for the steps. It needs a leg strap, but other than that, it's an awesome game. It will give you a full body, cardio workout. You wont regret it.
