He wanted to begin his wrestling career immediately after high school, during which he was also a highly-ranked football player, but his parents encouraged him to go to college first.
[7] On the March 29, 2021, episode of the podcast The Arn Show on the Ad Free Shows network, it was revealed by Lunde's father Arn Anderson that Lunde had signed a contract with AEW and had been training by Q. T. Marshall and Glacier at the Nightmare Factory, AEW's training facility.
In an interview with Tony Schiavone, Lunde alongside his father and performer/executive vice-president of AEW Cody Rhodes, announced that he would be wrestling with the company as Brock Anderson as a new member of the Nightmare Family.
[11] In response to the debut, Jim Cornette said that, despite many positives, Brock’s lack of experience showed and he needed more matches in front of smaller crowds before he should return to national television.
[3][13] In July 2022, he teamed with Brian Pillman Jr. to challenge the Rock 'n' Roll Express as part of Ric Flair's Last Match.
The Andersons then won their debut match against Jay Lyon and Love, Doug at the event and post-match, they aligned themselves with Fish and Gosselin.
In high school Lunde played football, being ranked 94th among graduating linebackers in North Carolina and 904th in the United States.
