    Do you profit more from the penalty than the membership with this model? I’ve heard that regular health club profit most from signing uncommitted people who rarely use the facilities. That way, they can get more members without reaching maximum capacity. Is you gym at its capacity all the time?

    This next question is not specific for Gym Pact, but why do most personal trainers work in multiple health clubs? It doesn’t seem very efficient. Am I missing something?
