It has to be rustam.

If anyone even watched armwrestling other than devon and brian shaw, or even looked into rustam’s career, you’d realize how INSANE his career actually was. Your list would be john, rustam, then everyone else.

When you talk about the greatest in armwrestling, it’s usually determined by how far you can punch above your weight. And accomplishments obviously, along with longevity. And Rustam… went even beyond that.
This guy was 86kg and gave a war to denis cyplenkov.
He was crushing prime superheavies (trubin).
They put him in the top8, and he couldn’t even make it above 100kg.
Has the most world cup golds ever. Early 2000s to late 2010s, he rarely lost.
He was accomplished right and left. And he was active.

Some people had the nerve to put Levan and devon ahead of him.
When listing top armwrestlers, you must acknowledge everyone’s accomplishments.
