While I agree with previous reviews that the images on the cover dont match the actual content I love this game! It's totally addictive. As I love boxing based routines this is perfect for me. I'm quiet active, going to the gym 3 or 4 times per week, so I wasnt expecting to get too much of a work out from this but I was sweating buckets and my arms were aching after my first session. I've been doing 45min sessions every other evening but find it difficult not to do it every day! I would recommend this to anyone.
