[4] Kronk began to earn fame during the late 1970s, when prospects like Hilmer Kenty, Thomas Hearns and Mickey Goodwin trained there.
Among the many world champions who trained at Kronk at least once during their careers are Michael Moorer, Wilfred Benítez (in the Tucson gym), Héctor Camacho, Julio César Chávez, Naseem Hamed, Evander Holyfield, Lennox Lewis, Jermain Taylor and Tyson Fury.
In September 2006, the original gym at 5555 McGraw Avenue between 33rd and Junction Streets in Detroit closed temporarily after thieves stole copper water pipes, cutting off supply to the building.
A "Save the Kronk" campaign aimed at keeping the facilities from closing due to budget shortfall was spearheaded by Emanuel Steward.
The card was headlined by Kronk fighter Vladimir Shishkin who defeated Oscar Riojas via ninth-round technical knockout.
