To anyone watching Simone Biles perform, the 28-year-old is a literal machine. But the most decorated gymnast in history is sharing the truth about the impact an event like the 2024 Paris Olympics takes on even the most practiced athlete’s body.

Well, we know that Simone Biles will be physically at the 2028 Olympics in Los Angeles. What we don’t know is whether the undisputed GOAT of gymnastics will be there as a spectator or as a competitor, because Biles doesn’t know herself.

At 28, Simone Biles has already accomplished what few others do in an entire lifetime. She holds 11 Olympic medals, including seven gold, and a record 30 World Championship medals, including 23 golds, making her the most decorated gymnast ever.
