There's still a big debate as to whether size matters. But in the case of some of these MMA fighters - and this list - it most certainly does. This list is of the heaviest MMA fighters to ever step foot in the ring or Octagon.
These men look like they could easily be served well to hop on a treadmill or the biggest loser, but they are - by definition - professional athletes regardless.
So without further ado, let's dive right in to these big boys.
