Dancing well, dancing badly, dancing outlandishly, dancing alone or dancing in a crowd - whatever kind of dance you're moved to do, you're doing your part to stay fit. Dancing makes for a great cardio workout that doesn't feel like a workout at all - done right, it should feel more like play. One half hour of dancing burns 200 calories while simultaneously relieving stress and, we hope, making you smile. As with any cardio workout you should stretch for a minimum of 5 minutes beforehand to prevent pulling or straining your muscles. In high temps do your dancing in the cooler hours of the day.
