A young man is stepping up and down in a forward motion on a step apparatus in a gym studio and his arms are also moving forwards and backwards.  He steps across the step board to the opposite side.  Then he steps across the board so he is backwards.  And then moves around the side of the board.  He proceeds to go all the way around the board in different directions.  He makes a turn around the board.  And continues to cross the board in all different directions while dancing.
