The whistle

0–4s

“{{YEARS}} teaching PE. Then I built a kettlebell.”

Vertical 9:16 talking-to-camera shot, phone on a tripod at eye level, medium close-up. In a converted garage workshop at midday, a workbench with prototype kettlebells, a pegboard of tools, daylight from a side window, a 55-year-old Black woman with short grey locs, a bright coral polo shirt with a whistle on a lanyard, navy track pants and white trainers blows a short blast on her whistle, lets it drop on the lanyard, and smiles into the lens. She says: "{{YEARS}} teaching PE. Then I built a kettlebell." Static camera, soft side-window daylight, natural skin texture, shot on iPhone, vertical 9:16, unpolished. No captions or on-screen text. (Generates 5 s — trim to 4 s in the edit.)

Why it works

A PE teacher has instant authority without making medical claims, and her origin story (kids waiting in line) explains the product's single big idea. The prototypes-on-the-bench shot signals a real maker, and the coach-style CTA turns 'buy' into a friendly order.

Hook variants to A/B test

  • “I spent thirty years watching kids wait for a kettlebell.”
  • “Retired PE teacher. Now I make one thing.”
  • “Coach's whistle, then a product story.”
