I firmly believe it does. Ok Ill just use Andrew since there's plenty of visual evidence on You Tube. Against Dumas he sauna suited to make weight,and he spent most of the fight on the canvas. In his most recent fight,we watched his diet and changed his work outs,and he came in way under weight,but did it in a healthy manner,and quite arguably won the fight,and other then feeling a bit sore, felt fine afterwords
Same thing with Feur,at middleweight she's a little chinny,at her natural weight of super middle,Ive seen her blow off hard shots from strong heavyweights without blinking.
