This stuff is definitely gonna be breaking the stereotype that gamers are out of shape. I was playing the baseball game yesterday til I went pro which requires winning so many games against better opponents ranking wise, pitching really well and putting up some massive home runs. Well it took a good 4 hours and in order to pitch the ball, you have to move the remote in a pitching motion (the faster the movement, the faster the pitch) and in order to bat you got use it like a bat (the faster the snap, the harder the hit).
My right arm is completely shot and will be for another day or two. It has seemed to work out every single muscle from my forearm up to my shoulder. I threw atleast 500 pitches and when you couple that with the batting attempts, its a workout. The boxing game is even worse. Even my friends that are the best conditioned can barely make it into round three of that (and the round clock is accelerated). Even has a fitness regimen you can go on to test your physical age. Good investment for everyone from the casual to the hardcore gamer.
