Inside the gym, it was noisy, with people breathing hard and gloves hitting pads with a sharp sound.
As fighters moved across the mats, they locked up in pairs to practice.
They were all wearing their training gear, with mouthguards on, gloves on, and shin guards tight on each leg.
In the middle of it all, the guy from Philadelphia and the guy from Brazil circled each other. They were already in the middle of a spar.
Both of them were focused, and as they moved, drops of sweat ran down their faces.
As he looked for a way in, the Philly fighter kept his hands up and his feet moving quickly.
Across from him, the Brazilian maintained a wide stance, his dark eyes sharp and focused.
They were wearing standard protective gear, but that didn't stop the intensity.
Philly threw a quick jab, testing the distance, but the Brazilian slipped it with ease and fired back with a hard kick to the body.
