“A 'gym girls thank me later' selfie hook you can use to market a health & fitness app - cutting directly to screen recordings of visual muscle fatigue maps.”

This app demo TikTok post pulled 2.8M views - 2659× what the account typically does (~1.1K views on a normal post). That gap is what Handler calls an outlier: the breakout came from the content's structure, not the account's size.

Engagement pull sits at 2/5 (1.9% weighted), measuring how hard the post moved viewers to save, share, and comment - the actions that signal real intent, weighted heaviest. The product behind it: A workout-tracking app.
