The difference between Open GYM and Extra practice is that we offer classes and programs for Age group Classes and Teams but we don't offer classes for Adult, Tumbling. Preschoolers learn by exploring their environment and not so much structured but definitely supervised. And for the adults or Tumbling we don't offer classes, so that is why it is not an extra practice !!!
