Athletes have taken part in gymnastics since ancient times. The physical maneuvers, the equipment used, and the rules that govern the sport have changed a lot over the centuries.

Many people think that some of these long-standing records will never be broken. Part of the Unbreakable Sports Records? series, Gymnastics Records That Will Be Tough to Beat tells the stories of five gymnastics record holders whose personal bests might just stand the test of time.
