So what is this Mighty Mick’s all about? Well,¬†Mighty Mick’s Gym was a gym managed and owned by Mickey Goldmill, manager and trainer of Rocky Balboa and a former boxer himself. After Mickey’s death in 1981, the gym closed and remained dormant for a long period of time. Several years later, after filing for bankruptcy because of a crooked lawyer, Rocky reopened the gym which Mickey willed to his son Robert Jr. Besides Rocky, other boxers who trained at Mighty Mick’s were “Big Dipper” and Tommy Gunn.
