Although dancing is an exercise in itself, I still like to inject hours of structured workout. I like to run because like dancing, it also has some kind of rhythm.
I am more comfortable running indoors so my treadmill is extremely maximized! I have one which has all the basic features (and some) enough to give me some calorie-burning workout at home. I don't need the sophisticated models, anyway. If you are in search of a treadmill, there's a list of good ones which do not cost so much. You can find it here.
Get moving and you'll be surprised at how good it will make you feel!
