Gleason's is a boxing gym located on the Brooklyn waterfront. Since 1937, when the gym was founded in the Bronx, boxers with their eyes on Olympic glory or a shot at the title have been training at Gleason's. Fighters who trained at the gym include Jake LaMotta, Roberto Durán, Benny "Kid" Paret, Gerry Cooney, and Mike Tyson. Before his first title fight against Sonny Liston, Muhammad Ali, then known as Cassius Clay, also trained at Gleason's.
