Maybe motivation is the final step before start practising any physical exercise, and that's what this game achieves. This is not a gym (also it does not work for pro trainings), but it's perfect for people without time/money for it to be a casual, and those who want to start a good lifestyle.
As a game, there is a lot of enjoyable modes and minigames. The adventure mode is long enough, with level mechanics, talents tree system, power ups, and and full of charismatic characters.
