Dear Folks: Stopped by Exodus, a local gym in Williamsburg, to ask about memberships. They had a sign out front advertising 99 for two months. I asked about it. It had been running for a few months. Then I asked how much are quarterly, semi-annual or annual memberships. They said they no longer offer them. I know they used to, as I had looked in about half a year or a year ago. This short-term-only policy seems strange. All gyms know that most members use the place very little. The active members subsidize the less active members, and most gyms want to get as much of your money as possible up front. Exodus has been in business for several years. What might be their reasons? Please advise.
