Many pictures filled the walls of the Pound for Pound gym, but one that stood out most for owner Bernard "Swift Kick" Robinson was the one signed by the greatest.
He got it at an auction during a celebrity golf tournament, but that's not all.
"Ali was only there for 10 minutes, but we got to meet him," said Robinson. "I shook his hand, and it was awesome."
Especially for an up and coming fighter who's now a trainer, a two-time world kick-boxing champion and a boxer with 46 fights under his belt.
"People say we lost the champ, but I say we lost a king because if it wasn't for him, I wouldn't have gotten the accolades and things that I achieved," said Robinson speaking of Muhammad Ali.
Those feelings were shared by every boxer in the building.
Mardae Weaver, a personal trainer, MMA fighter, and boxer, said the news of Ali's passing hit him hard.
"He never knew that I existed, but the moment I heard it, it was like a cousin or an an elder at the church had passed, and it was like, man," said Weaver.
Weaver admired him for being a champion both inside and outside the ring.
"With eight knuckles he was able to show that you can stand up, and it's okay to be different and stand out,' said Weaver.
Boxer and trainer Deon Giddens said Ali taught him to overcome obstacles.
"I think watching him do what he did, it kind of inspires you to keep pushing no matter what the circumstances were," he said.
And even though he's gone, Ali's presence will forever remain in the hearts of boxers.
"He opened the door for so many of us, and a lot of people don't understand in this fight game it's a dog eat dog world," said Robinson.
A memorial service was held Friday for Ali in his hometown of Louisville, Kentucky. You can see that in the videos below:
