Bring a refillable water bottle to refill water rather than use disposable cups.
Wear comfortable clothes that allow you to move and stretch.
Dance shoes if you have them. Dance shoes have suede on the soles which provides a perfect balance between grip and slide. If you don't have dance shoes wear a pair of shoes with a bit of slip.
