Elisabeth Akinwale, who trains at CrossFit Construct in Chicago, says CrossFit makes her a better person and forces her to face weaknesses.

"I have a coach now," she says. "Your body is the physical result of a lot of people's work."

Akinwale finished 13th in 2011, and 7th at the 2012 Reebok CrossFit Games.

Akinwale is not only a two-time Games athlete, but also a mother. "Your family makes a lot of sacrifices so you can be able to train. And I think winning makes it feel like that was all worth it."

The 2012 Reebok CrossFit Games will re-air on ESPN2 starting Dec. 16.
