According to the former welterweight (up to 77,1 kg) and middleweight (up to 83,9 kg) champion, while physical condition is essential for the performance of a high-performance athlete, the most important aspect for an MMA fighter is having the ability to understand how to apply their energy intelligently and effectively throughout the fight in order to avoid exhaustion.

“I don’t believe much in cardio if you’re a combat athlete, I believe in efficiency. Even if you’re in better shape than me, but if I’m more efficient than you, you’ll tire before me.
