What does it take to become a powerhouse Olympic bobsledder?

Two-time Olympic hurdler-turned aspiring Olympic bobsledder Lolo Jones now knows it takes solid muscle mass, some spark and a goal of reaching 160 pounds -- and she's almost there!

"I'm the heaviest ever in my life," the 31-year-old said, thrilled to weigh in at 157 pounds, USA TODAY Sports reported.

It wasn't an easy goal to achieve, the rock-solid athlete said, "It took so much work. I'm three pounds away from my ultimate goal."

In order to push a 400-pound sled, it takes a lot of force and a 9,000 calorie a day diet, which most women would find daunting. But for Jones, it was a challenge she fully embraced to gain her way to the top in a sport that's based on the motto, "mass pushes mass."

It's refreshing to see women empowered by their strength, instead of worrying about looking slim while withering away.

"I'm pumped about this muscle weight," Jones told USA TODAY Sports. "My abs are still there. I'm still cut, just super solid."

So what does Jones eat?

Let's just say Jones has a weakness for McDonalds and a need for its high calorie content.

She told USA Today that she makes late-night runs to Mickey D's for double bacon cheeseburgers and drinks two protein shakes (1,365 calories each). A far cry from her Olympic hurdle days where "you eat an M&M and you think your career is over," Jones explained.

ABC News pointed out that Jones isn't the first Olympian to make headlines for calorie consumption. Instead, "swimming sensation Michael Phelps was widely reported to have eaten 12,000 calories a day leading up to the 2008 Summer Olympics in Beijing - though he says that's a myth."

Women's team trials begin Oct. 12 in Lake Placid, N.Y., and the Winter Olympics in Sochi, Russia take place Feb. 7-23.
