Those who go to the former Gleason’s gym these days aren’t there to fight, but to stay in shape for its own sake:

When Gleason’s left Manhattan in 1986, the gym had 200 members, 90% of whom were competitive fighters. Not a single woman belonged to the gym. Top-end pros like Gerry Cooney and Roberto Duran were regulars, and the gym’s history with Jake LaMotta, Muhammad Ali and others gave it international fame. But the fees from the small membership couldn’t cover the Manhattan rent. Silverglade said the move to Brooklyn was purely financial.
