Knee injury?

Aquafit! Okay, normally you think of old ladies doing it, but that's definitely not the case. The reason its so popular with them is because exercising in the water is good for your joints... they don't take as much impact in water as they do on land. And if you're thinking its weird exercising in a bathing suit, its so not. You're under the water and its fun!

I used to teach it, and it can be a really great, fun workout with some great upbeat music. You get exhausted just teaching the class because you have to be talking to the class and demonstrating the whole time. Its usually not too pricey or busy if you plan to drop in on one. And if you're looking for a younger crowd, check out a University or college pool. If you do go, mention your injury to the instructor and they make have some alternate activities or specialized activities for you. There are a lot of options difficulty and workout-wise in aquafit. It can pretty much be tailored to the individual.

If you were looking for a Wii workout, sorry I haven't helped you... but seriously aquafit or working out in the water!

Good Luck!

You can do Wii Boxing while seated.
