This is why Ronda made the decision to make weight in 24 hours. The editing of the show makes it seem like Dana talked her out of it, but let me tell you what really happened...
Anthony tried to say that it just wasn't possible for him to cut the weight because he had screwed up on his diet. But here's the thing, he could have made it. He left the gym the night before at 144, which is well within a range to make the weight. There is a science to cutting weight and lots of things that we as fighters can do to make it easier on ourselves, but the BIGGEST factor in the weight cut is your mental fortitude...and this is what Ronda wanted to prove.
She jumped on the scale after Anthony missed weight and was 152 pounds. Without any sort of prep (diet, water loading, sodium loading/cutting, etc.) jumped in the sauna and was in there for FIVE hours before it was time to go to the coaches challenge. Yes, Ronda Rousey cut weight in the sauna for five hours, went to a rock climbing challenge, won, and then went BACK to the sauna that night and cut some more.
The next day when it was time for Jessica and Raquel to fight, she was at the gym before anyone else arrived and was back in the sauna cutting weight. When the rest of us arrived she was sitting at 136 pounds in the locker room. I watched her warm up Rakoczy for her fight while on weight and then step on the scale in front of Dana and be 135 pounds. She did this to prove a point.
