For a mixed martial arts fighter, the night of an event is the culmination of a process.
By the time they step into the cage, they've been through four, eight, 12 weeks of training camp, usually on a seven-days-per-week schedule. A typical day for a typical fighter might have consisted of multiple sessions of wrestling practice, jiu-jitsu, cardiovascular and strength work, and sparring, where fresh opponents were rotated in each round. And even though every hour of every day has been spent ensuring the goal of defeating a human being in physical combat, if they've made it to the cage, it means they have emerged from camp without injuries—or at least without injuries that would prevent them from fighting, because, truth is, no fighter can go through this and emerge unscathed.
