does anyone know how to get on the silver sneakers list?

I would look up your local Silver Sneakers representative. If you can’t find the person online, go to a gym in your area that offers it & ask who they contact. If you’re not comfortable doing it in your own town, just try one a few towns over. The reps often check in on a large area & typically have a gym job in addition to their coordinator position. https://www.silversneakers.com/tools/fitness-locations Good luck!
