If you are tired of excercising with you Mii and you are sick of running around Mii Island then this is something that is well worth a look. If you are looking to train like an adult with a trainer that is a bit meaner than a cartoonish Mii, then this is a disk you need to get. I have enjoyed WiiFit but this is much more intensive and focussed on my fitness and my goals. WiiFit for Fun – My Fitness Coach for change.
