Weight cutting and making weight has been an essential element of MMA ever since the sport introduced weight divisions.
Fighters will try and maximise their advantage in a contest by being as heavy as possible while dunking just under the bar on the night of the weigh-in.
The whole process is an exact science which requires skill and dedication to accomplish. But it takes its toll on a fighters body and there are some fighters that are just kidding themselves when it comes to what weight division they belong in.
