Antonio Brown put on blast by former trainer

Antonio Brown and his longtime personal trainer, Bo Smith, have parted ways, and by the sounds of it, things didn't end well.

Smith announced on Twitter and Instagram that he "will no longer be training, involved or associated with" Brown, referring to the Pittsburgh Steelers wide receiver as "bad business."

Brown also went through a very bitter and public split with his personal chef, Nicholas Hasapoglou, last year.
