The Supergirl stuntwoman, who has given everyone a run for their money throughout the competition series, was the first woman ever to complete Stage I during the Las Vegas finals.
Graff, 32, tells PEOPLE about her accomplishment: “I hope it will show women that feminine is strong – that we can frequently do more than people think we can – sometimes even more than we believe ourselves, if we’re willing to work for it.”
She continued: “We may have to train smarter and harder, but if we achieve greater focus, technique and strategy, we can beat the guys. I know I’m not the strongest or the fastest. There are plenty of women who can do what I did, but I’m honored and grateful to have been the first – to get to be a part of this huge movement in which we challenge our perceptions of what’s possible.”
And to celebrate Graff’s incredible moment, LEGO created the LEGO NINJAGO video, which was shared exclusively with PEOPLE. In the above clip, the toy company gives a very cute and fun spin on the American Ninja Warrior star at the finals.
Graff previously made history on the show as the first woman to make it up the 14.5-foot Warped Wall during the Los Angeles qualifiers – and she did it again during the Los Angeles finals.
American Ninja Warrior National Finals airs Monday at 8 p.m. ET on NBC.
