Must Be Thin
A British jockey weighs in at a horse racetrack near Manchester, England. Jockeys must satisfy strict weight requirements in order to ride in races. For many competitions, this means weighing 110 pounds or less. In an effort to stay thin, jockeys have been known to restrict their intake of food and liquid, sweat off water weight in saunas, and force themselves to vomit (Associated Press, 2008, April 25; McKenzie, 2012, October 23).
