Commercial is the style of dance you often see backing dancers perform on stage with pop/urban music, and in music videos for example. It is an extremely popular genre, with a mix of fast and slow movements and isolations, it is a brilliant work out that leaves you feeling energised and confident.
There is no uniform for this class, although dancewear must be worn, or clothing that allows you to move freely, no jeans! This can be any ensemble in any colour, this is a class where you can show off your wardrobe. Clean trainers and recommended, but sometimes you wont need them and bare feet would be most appropriate.
