8-year-old takes CrossFit community by storm

BILLINGS, Mont.-- An 8-year-old girl is taking the CrossFit community by storm.

Brooklyn Sittner trains with her dad and competes with people twice her size. She exudes self-confidence.

"You just have to believe you can lift. There's no way you can do CrossFit if you didn't like, believe in yourself," said Sittner.

Sittner hopes to compete in the CrossFit games when she reaches the minimum participation age of 14-years-old.
