<p>It's a muggy August night in Beijing, and Usain Bolt has just conquered the world yet again by claiming a gold medal at the 2015 IAAF World Track & Field Championships.</p><p>How does the sprinter celebrate? A brutally cold ice bath in a Beijing hotel room.</p><p>"S--t's about to get real," he says, before gingerly submerging his legs into a hotel tub filled with ice water. He winces. More ice is added to the tub.</p><p>"This is my celebration," Bolt says, completely deadpan. "More ice. So much fun, right? No it's not."</p><p>It's one of the many behind-the-scenes looks at the Jamaican's training routine in I Am Bolt, the new documentary</a> about his astounding career—nine gold medals, eight world records, 11 world championships—and his life as the fastest man in the world</a>. Directed by Gabe and Ben Turner, I Am Bolt offers a rare look at the Jamaican superstar's training routine, alongside the glamorous (cheering fans, national hero status) and not-so-glamorous aspects (ice baths) of being a world-class sprinter.</p><p>Bolt's take on the latter? "Listen, man: True champions take ice baths." (Science disagrees</a>—but seeing as Bolt went on to win golds in the 200 and the 4x100, we're not gonna argue with him.)</p><p>See I Am Bolt in theaters and Digital HD now, or get it on DVD starting December 6.</p>
