4.5 Great work outs UsedBooksandGames | 18/03/2012 | See all UsedBooksandGames's reviews (14) I wanted an exercise "game" that was more manly than the dancing type games that are more readily available. I knew I was unfit and after my first (easy) workout I knew just how bad I was. I'm now well into the 21 day fitness programme and can feel the benefit. Sometimes when doing the ground exercises the monitors don't always pick up the movements but this might be because you are not doing the exercise quite right. I would recommend this as a good exercise game with plenty of tough exercises to give you a good workout.
