We are heading into October, and many schools are looking for ways to increase enrollment. Why not start with the families you already have. They know the value of your program; you don't need to sell a membership, they love your program and they have seen your value.
Start October with a 14-day challenge, encourage them to work out together as a family. Many parents already have a fitness routine, persuade them to give it a try for the two weeks anyway. They will be surprised at the different muscle groups targeted.
Here is day one of Samery's challenge. You can create your own, or follow along with hers.
