Horrendously broken for kinect 360. Do not buy until they fix this unplayable game.
The menu system is also completely broken. Besides freezing as well, it can't understand your voice. You say trainer and a menu is suppose to pop up but the game is so glitchy the menu will hardly ever pop up and when it does you need to say a second command, good luck getting it to understand your second command when by some miraculous event it was able to pick up the first command. I never got past the second command, I have to use my hand to wave and select but that is also easier said than done because of horrible detection issues along with the freezing and glitching.
Videos will play sometime to teach you something but I've only made it through one video because the game would glitch and skip the whole thing. Also the trainers don't have many lines during workouts so expect to hear "Its not good to workout cold muscles" four times in a one minute warmup exercise.
As far as the exercises they seem pretty good so far, can't hate on that part, but expect your cardio tempo to slow down everytime the game freezes during each exercise.
I really regret buying this game. I've played a lot of fitness games and videogames in general but this game has too many glitches that destroy the core gameplay and overall experience. It is just too broken to recommend.
