Benas was born September 25, 2002, in Albany, New York, to Shannon and Adam Benas.[1] His parents gave him the nickname Fuzzy when they were getting a sonogram and wanted to know the gender – the nurse said the picture was "too fuzzy" to tell, so they started calling him that before he was even born.[2] His hometown is Richmond, Texas and he attended Travis High School. He enrolled at the University of Oklahoma to pursue gymnastics.
Benas became age-eligible for senior-level competition in 2022. He competed at the 2022 Winter Cup where he placed eleventh in the all-around.[7] He competed at the NCAA Championships where he helped Oklahoma finish second as a team. He was named College Gymnastics Association's Rookie of the Year.[8]
After the end of the college season, Benas underwent shoulder surgery and spent the next few months recovering.[2] In October he severed a nerve in his hand during a pumpkin carving accident.[2] Right after Benas was medically clear to restart training, he tore his ACL.[2] As a result, Benas did not compete during the 2023 NCAA season.
Benas next competed at the U.S. National Championships where he finished eleventh and was added to the national team.[14] As a result he qualified to compete at the 2024 Olympic Trials where he ultimately finished sixth.[15]
