Just dance: Ever since I found the best Zumba instructor ever, exercising has never been the same for me. Dancing will beat out almost any other gym class because, well, it doesn’t feel like exercise. Not only do I work up a sweat, but dancing makes me happy. Why not have a little party at home with the family? Jam to some merengue, bachata, or salsa. According to this calculator on Glamour.com, a woman weighing 130 lbs. can burn about 340 calories after dancing salsa for an hour.
