Fair enough. However, calorie burning is often used indiscriminately as the primary goal of an exercise, which is, well, silly. An exercise will likely do many things for you, even if it has a primary goal in your mind. If you forget that, say, running strengthens your calves or improve your everyday well-being, you will not quite realize how good it can be for you. If you instead focus on the fact that it burns calories, you're only getting a very small picture.
