An Olympic gymnast made a powerful statement during her floor routine this weekend ... by getting on one knee and holding up her fist as a tribute to the Black Lives Matter movement.
18-year-old Luciana Alvarado is the first Costa Rican gymnast to EVER qualify for the Olympics ... and used her platform to shine a light on the fight for equality.
Of course, the International Olympic Committee is allowing athletes to demonstrate at the 2020 Games in Tokyo ... as long as it's not at a medal ceremony or during competition.
