In every program the issues of funding and sustainability are prominent. EnhanceFitness is often begun through grant funding. These grants come from various agencies and are vastly different in size and scope. Programs spend the money to train instructors and create the infrastructure to teach the classes. Many programs offer the classes for free to participants. In some areas the class is a covered benefit from their insurer. Some classes ask for donations and others charge for the class. What are your experiences with the sustainability of your program? How do you invest in a program and maintain it over time for program delivery? Are there any differences in program adherence when participants pay for classes? This is the biggest question from everyone delivering the program, so would love to get some comments and discussion!
