Kronk was the home base for many champions, including Tommy Hearns, Hilmer Kenty, Milton McCrory, Mark Breland, Frank Tate and Michael Moorer. Steward also trained stars such as Oscar De La Hoya, Hector “Macho” Camacho, Julio César Chávez, Evander Holyfield and Lennox Lewis at Kronk.
The Kronk Gym was in Detroit, and obviously was owned and operated by Emanual Steward, and yes, Tommy Hearns trained at the Kronk - remember the famous Gold trunks with Kronk in Red letters....
