I would give it a go! The moves and exercises will take some getting used to, but once you have cracked them they will come to you easy!
I have just finished my first training session. Need to sit down!!!! hahaha!
It seems that this game only weighs you weekly rather than daily (unlike wii fit body test) which is a shame, I like the daily weigh ins!!!
When you initially start it does take some time, so if it's anything like my house you'll have to prior warn people that the lounge and tv is out of bounds for 30 mins!!! lol
Enjoy!
