Doctores Grip Battle 2 · Sep 6, 2025
Each athlete ranked by their best lift for the filters chosen, across every source (heaviest, longest hold or most reps first). A lift a body lists as both a record and a contest result is shown once, as the record. An athlete listed by two bodies appears once per body.[1]

How records work
Records are set under a sanctioning body's rules — set, judging, and equipment all matter. A lift in your garage counts for you; a lift on the platform counts for the books. Each entry here is owned by the body that published it, shown by its badge and footnote.
Sanctioning bodies →Chasing a mark?
Records are set at sanctioned contests. Once a meet's results are posted to the owning body's database, new marks show up here at the next sync. Spot an error? Let us know.
