A videó leírása: Christine Pereira was unhappy. At 270 lb., she felt trapped. Literally. "Before CrossFit, I was miserable by being in a body that I felt didn't match my inside," Pereira explains. "Everything was impossible. Everything was difficult ... just every day, going up the stairs. I was truly unhappy." Pereira also felt helpless. She would browse magazines, thinking there was no way she could ever be as slim as the models pictured. "I didn't think it was possible. Not at all," she says. "I was gonna be that big, fat person for the rest of my life?that's what I thought." That all changed when she found Brethren CrossFit in Morgan Hill, Calif. Today, the 34-year-old is 177 lb. "It's made me so much more secure in myself," Pereira says. "I feel like I just started my life." Video by Jay Vera.
