The prompt

Copy the complete prompt (it wraps the request below so the AI returns a clean, runnable session).

Write me a 15-minute sprint-interval workout on a bike, rower or for running. After a short warm-up, give me 4 to 6 efforts of 30 seconds near-maximal with 2 to 4 minutes easy recovery, then a brief cool-down. The hard efforts are genuinely all-out; the recoveries are easy. Give each block a duration and a target effort or heart-rate zone, grouped as repeating intervals.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Brief, all-out sprint intervals — just a few minutes of hard work inside a short session — drive fitness adaptations comparable to much longer endurance training. The evidence comes from small studies, but the effect is real and remarkably time-efficient.
