"I was hitting pads for maybe only 30 seconds, and I was just gassed," he said. "I couldn't believe it. I thought, 'I'm in much better shape than this. Why am I so tired just warming up?' Then all the negative thoughts took over. 'What if I lose in front of all my friends and family? What if I look really bad?'"
Things didn't get much better when the fight actually started.

There's a name for this phenomenon: "Octagon jitters." It's when the pressure of performing on the biggest stage in MMA causes a fighter to freeze up.

There is, however, one upside to freezing up and turning in a horrible performance your first time in the UFC.
