Hi Lisa! No we don't use mirrors. When we rehearse we use mirrors just to see how we look for a couple of times. After that we face a wall so that we don't get too used to relying on mirrors. I personally prefer no mirrors. It allows me to focus more on you.
Clare you are so exactly right on with this observation......"Cathe rehearses all future video moves on her gym class students first, so she knows what the temptations are.....and she suspects we'll be doing them right along with everyone else!"
