This isn't April 1, so: I'm sorry, but this is just ... silly. Our normal walking gait evolved to be efficient for our anatomy. Of course any variation is going to be less efficient and therefore better exercise. The whole point of exercise is to move inefficiently so that your muscles have to work harder in a given span of time than they otherwise would. There is nothing special about silly walks in this regard. You can be inefficient without being silly, it's just hard to be silly without being inefficient.
