Fit viewers believe training protects their heart, and this packaging removes that comfort. The runner clutching his chest says it can happen mid-stride. The real heart held in gloved hands makes the threat feel physical, while the title aims the risk straight at fit people.

Use this when your topic threatens the exact people who feel safest from it. Name them in the title so the even-you framing lands, and keep the threat true enough that nobody can call it scare tactics.
