Kate Foster is a gymnast from Illinois and she will shock you with her incredible beam routine...with a twist.
Foster has a prosthetic leg.
After being diagnosed with leukemia in 2011, the then-15-year-old gymnast and CrossFitter lost her leg to a cancer-related infection in her knee joint. But after taking some time to heal and kicking cancer's ass, she is now back in the gym five days a week.
