Honourable Mention: Chellsie Memmel's 2021 Gymnastics Comeback Before I leave you to dream about the upcoming year of gymnastics, I'd be remiss not to call attention to Chellsie Memmel. She's a gymnastics veteran — she won world all-around gold in 2005 and Olympic team silver at the 2008 Beijing Games — who, at 32, came back to the sport after almost a decade break. She competed at the GK US Classic in May and Nationals in June this year. And by the looks of it, she's not finished yet!
