A proof of the physical demands this sport requires is the early retirements we often see. Athletes over 30 are typically considered close to retirement age, as maintaining peak physical condition becomes increasingly challenging.

The 27-year-old gymnastics superstar with seven Olympic medals, Simone Biles, is well aware of this reality. In her docuseries Simone Biles Rising, part two, fans get an intimate look at the journey of the gymnastics G.O.A.T. as she prepares for the Paris Olympics. She humorously acknowledges that her age is “old for a gymnast” and that she has to be more careful, describing herself as feeling like “a ticking time bomb” for an injury.
