In Creed, what is the name of the gym where Rocky trains Adonis?

In Creed, Rocky trains Adonis at Mighty Mick's Boxing.

The gym is named after Mickey Goldmill, Rocky's longtime trainer. It is a continuation of the training environment associated with Rocky's career, although the original gym was often referred to simply as Mickey's gym or Mighty Mick's Gym.

Adonis seeks Rocky because he wants more than technical instruction. He wants to understand the standards and discipline that shaped Apollo Creed's greatest rival. Rocky initially hesitates, but he eventually takes on the role of trainer and helps Adonis prepare for his first major bout.

The gym symbolizes continuity between the original series and Creed. It is also where Rocky's practical boxing knowledge meets Adonis's modern athletic ability, creating a partnership that drives the film's training story.
