Since former Olympic hurdler Lolo Jones joined the US bobsled team, she's been on a very different training regime: downing 9,000 calories a day to build up the bulk required to push her 400-pound sled. Jones just hit 157 pounds, up from her track weight of 133 pounds. How did she do it? Drinking high-calorie protein shakes and eating double bacon cheeseburgers from McDonald's, she tells USA Today. It's a big menu change from her former sport, where "you eat an M&M and you think your career is over," she says. But Jones insists all those burgers are helping her put on muscle, not fat. "My abs are still there," she says. "I'm still cut, just super solid."
