wii fitness game recomendation

It's technically not a fitness game, but "The Black Eyed Peas Experience" can burn some cals! It's a dance game, and 2 songs that'll definitely give you full body cardio workout are "Pump It" and "They Don't Want Music". I usually start with those because they'll get your heart rate up quick.

I bought EA Fitness 2 and it's "More Workouts" sequel a couple of weeks ago but haven't tried them yet.

I Redbox'd "Just Dance 4" this past weekend. Less intense but more fun (as in "ha ha"); I'll buy it once I can buy it used.
I'm a cheapskate with games; I buy used/pre-owned most of the time and even then only when it drops below $20. The most I've ever spent on a Wii game is $40, but it came with a new remote that would've cost $30 by itself. I got my Balance Board new on Black Friday 2010 for $68. To this day they still want $80-90 for it new, don't know if they sell used ones.

Love Zumba Fitness for Wii. I use it like 3 times a week.
