I have thought moving to a paperless tablet would be a great way to go in the gym.
The up front fee would be negligible, because the tablet has lots of other uses.
However, I decided not to do so because of a learning curve. I feel that if I struggle with a few clients when Im beginning to use the new system problems may arise.
If you decide to do so Id love to hear how you do it and how the process goes. Perhaps using it for a few weeks to get the hang of it before using it out on the floor would be the best idea.
