UGH now i know what game you mean LOL i just got it recently but didn't notice the "personal trainer" on the box LOL just through it was called EA Sports Active.
i like this game alot. its not as hard as say cathe but its pretty fun way to workout. the band that came with it is to light so i use my tubing for the upper body workouts, lower body uses NO resistance and the cardio is unique and fun. i am particularly fond of the track segments. also love the build your own workout options b/c you can pick segments and exercises YOU want unlike fitness coach,which i do like, but don't like that i can't pick my exercises.
all you need is your wii,remote,nunchuck, and leg strap with the game. you can use other bands or tubes b/c the movement is monitored by the remotes obviously so you can basically use anything you can hold for resistance. its a bit touchy though so if you move slightly it will show on the screen that your aren't sitting still or your remotes are not facing the correct position for the exercises(have issues when doing curls or back rows)
overall its a great little workout game. i am wanting gold's gym cardio. i rented jillians and didn't care for it, i much rather have active.
