40 mins of Zumba Fitness on the Wii.
It's actually a pretty decent workout (in my opinion). It's definitely enough to get me in the weight-loss region of heart rates but not high enough for the cardio region (I did the medium intensity workout today...there's one higher and one lower).
They try to throw in a lot of lunge type moves into the dance so that you are working some leg muscles.
The only thing I didn't enjoy was how much jumping around I had to do! Like literally jumping up in the air over and over again. I didn't think I'd need a sports bra just for dancing but I'll surely be wearing one tomorrow.
