Two consecutive 25m all-out efforts with fins. First attempt: 31.8 seconds. Verbal reframe — "fast, fast, fast, use your legs" — and the next attempt, no rest change, no equipment change: 26.33 seconds. That is an 18% improvement from a single cognitive prompt. The fins didn't change. The water didn't change. Only the frame did. For sprinters, the ceiling isn't always technique, mobility, or fitness. Sometimes it's the swimmer deciding to actually sprint.
