What are some fun ways of burning calories that are nearly effortless lol?

Everything you do burns calories, just not a significant amount. You have to put effort into calorie burning, sorry. But there are fun ways to do it. I put in music while I clean my house and dance around to it, my dog gets in on it and we end up running around the house together playing and dancing. So that's pretty effortless because its fun and not something I consider "exercise", but it burns calories. Most likely the best way for you is to go shoot some hoops or play some soccer, ride a bike or skateboard. All sports are exercise.
