When you fill your car with fuel, what are you buying - a tank of fuel? No, when you think about it, what you're really buying is a destination. And so it is with your club membership - it's not the little card that you bought, it's that personal goal you have for yourself. The magic of BodyPump (or any class, really) is that there's a schedule attached to it, and so a certain built-in accountability starts to happen. You've got that time blocked off, and so you're going to be there. And being there is what ensures you'll reach that destination!
