A common feature of many of our arts is many instructors use a foundational footwork/body management exercise. In Tomiki Aikido we use "The Walk" known in various groups as Unsoku, Tandoku Undo, or Tegatana no Kata. I'm always looking for interesting looking exercises, and this looks to be a good lesson on a fun footwork exercise. Don't be surprised if you show up one day and find a circle chalked on my driveway.
