Jiří Procházka, former UFC light heavyweight champion, talked about how he tests his body.
"One time I did 1000 burpees in a row. Sometimes you want to find the limits of your physical abilities. And when you do, you realize that doing something like that often is not worth it. But you must do things that make your body uncomfortable, that's how you feel alive, focused, fast, strong," — Procházka's words are quoted by the Low Kick MMA portal.
