Nick Mangold is waiting to play football; his sister has already moved on from the sport.

Holley Mangold, like Nick, played center in high school, but the 323-pound woman gave up football for weightlifting when she got to college. She now plans on trying out for the 2012 Olympics.

“Training is going great,” Holley told SportsNewser. “I did have surgery about four months ago, but two months after that surgery, I went and competed and was back up to the weight I was doing before. Right now I’m hitting numbers that I’ve never hit before. It’s going really good.”

She says Nick played a role in her high school football success: “He was a huge influence.”

“I don’t know how happy he was about having his little sister play football in the beginning. Once I started playing and he realized I wasn’t going to quit, he just wanted me to do everything right and be the best I possibly could be. He even drove me to some weight training practices — he was very supportive.”

Holley’s story will be featured on MTV’s “True Life: I’m The Big Girl.”
