At first sight, it seems like the person is running while smiling and having a good time. To dance music fans, shuffling is more than just having a good time. As with most things EDM-related, it is a form of self expression, an accomplishment, and as some put it “a way to improve their mental and physical health”.The Shuffle dance was developed in the 1980s, it is improvised dancing where the person repeatedly “shuffles” the feet inwards, then outwards, while thrusting their arms up and down, or side to side, in time with the beat.
