How it works

Where the numbers come from

Each number on the site has a public source: an interview, a trainer's statement, an official race result, combine testing, or a video that shows the weight on screen. Each record links to that source and quotes the line that states the number.

Most celebrity numbers are training sets. They are not maxes. "Benched 225 for 8" is a normal workout, and we show it that way.

How lifts are compared

Lifts rank by estimated one-rep max. Up to 10 reps we use the Epley formula: weight × (1 + reps ÷ 30). A set of 225 lb × 5 counts as about 263 lb. Past 10 reps Epley overshoots, so the estimate follows the Mayhew curve, which researchers fitted on bench press sets with many reps, such as the NFL combine test of 225 lb for as many reps as possible. Estimates from long sets are rough.

Pull-ups, push-ups and dips rank by reps in one set without added weight. Runs rank by time, and jumps by height or distance.

Confidence

Submissions

Anyone can submit a record with a link to its source. An AI reads the source (a YouTube video, an article, or an uploaded clip) and reports whether it shows the claimed number. A person then reviews it. Only reviewed records show on the site. Uploaded clips stay private.

Corrections

If a number is wrong, submit the correct record with its source and say what it replaces in the notes.
