I've been talking a lot on facebook about my new fitness class that I joined (and FREAKING LOVE!!!!!)
It's called Groove fit... and you GROOVE your workout! If you can find a class near you (it's pretty new... but keep checking!) GO GO GO!
You can do this class if you are 500 pounds. I COULD have done this class at 377. You can kick it as hard as you want or take it to a level that works for you. People with mobility problems have done it while seated. IT'S FANTASTIC!
