Tucked inside the jockeys' room at Hollywood Park are quarters of private suffering.
In back is a large, glass-windowed sauna, known in the riders' vernacular as the hot box, or sweat box.
There, jockeys wring water and pounds from their bodies, sweating in stifling temperatures for up to three hours a day, some of them working out on a step machine as they swelter.
"I've seen some guys pull seven, eight pounds," Hall of Fame jockey Mike Smith said. "That's ridiculous."
Signs posted in the bathroom area suggest another method of weight control: "No heaving in this stall."
One, however, is reserved for that purpose, with a large basin installed at a height convenient for regurgitating.
"You go in a stall and there's someone in the next stall having to heave," said Smith, one of the fortunate few who can maintain a weight of about 113 pounds mostly through diet and exercise, but who occasionally uses other methods. "It's just a way of life in there. We almost joke about it sometimes, like, 'Don't eat the chicken.' It's sad, really."
