The prompt

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

Write me a 35-minute brisk walking interval workout for a woman in her 40s to build aerobic fitness and support energy and heart health. Start with 5 minutes easy, then alternate a few minutes of brisk walking (heart-rate Zone 2, breathing harder but able to talk) with easy walking, building the brisk portions over time, then cool down. Give each block a duration and a target heart-rate zone or effort.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Brisk walking counts toward the 150–300 minutes of weekly moderate activity that supports heart health and healthy ageing, and it's one of the most sustainable forms of cardio. Build the brisk intervals up gradually.
