Physio built the homework people actually do

The sheet nobody used

0–4s

“I gave out hundreds of these. Almost nobody did them.”

Vertical 9:16 static medium close-up, talking to camera. A 37-year-old white woman with freckles and long copper-red hair in a side braid, wearing a navy quarter-zip top, grey trousers and a silver smartwatch, in a small studio with a padded table, a foam roller and resistance bands hanging on a wall hook, laptop on a side desk. She holds up a crumpled printed exercise sheet covered in stick-figure drawings, lets it drop out of frame, and looks straight into the lens, calm and direct. Static camera. Soft diffused daylight through frosted glass, natural skin texture, phone on a tripod at eye level, unpolished talking-head feel. She says: "I gave out hundreds of these. Almost nobody did them." No captions or on-screen text. (Generates 5 s — trim to 4 s in the edit.)

Why it works

The founder's credential and her admission of failure arrive together, which makes her more believable than a polished pitch. The demo shows the fix to the exact problem she named (length and video), and a quoted review closes the loop in a customer's words.

Hook variants to A/B test

  • “Physios know a secret: almost nobody does their home exercises.”
  • “I built an app because my paper handouts went in the bin.”
  • “Here's what happened to every exercise sheet I ever printed.”
