How do I actually follow this cardio workout once the AI writes it?

Paste the AI's reply into sweatcue. It structures the session into timed blocks with auto-starting rest timers and calls every set, rest and rep out loud, so you train hands-free instead of scrolling a chat window.

Easy rest-day walk or spin

Q: What is the best ChatGPT prompt for a walking & cardio workout like this?

Use the research-backed prompt on this page: "Give me a 30-minute easy cross-training session — your choice of brisk walking or steady cycling — for a rest day from running, to build aerobic base gently without the impact of running. Structure: 5-minute easy warm-up…" Copy the full version with the button above — it wraps the request so ChatGPT, Claude or Gemini returns a clean, followable cardio workout you can run hands-free in sweatcue.

The prompt

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

Give me a 30-minute easy cross-training session — your choice of brisk walking or steady cycling — for a rest day from running, to build aerobic base gently without the impact of running. Structure: 5-minute easy warm-up to ease in; then 20 minutes at a steady, comfortable pace where I can hold a full conversation (roughly Zone 2, about 60-70% of max heart rate, RPE 3-4 out of 10 — never breathless); then a 5-minute easy cool-down. If I'm using heart rate, give me a quick way to estimate my Zone 2 ceiling from 220 minus my age. Tell me this should feel genuinely easy and recovery-like, not a workout I need to push through, and that the point is more low-intensity minutes, not intensity. Give 2 cues for keeping the effort honestly easy.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Low-impact cross-training on rest days lets a new runner add aerobic minutes while sparing the legs the repetitive impact of running, which is useful when bones and tendons are still adapting. Keeping it genuinely easy fits the well-established case for accumulating lots of low-intensity volume. The heart-rate zones here are a practical guide based on an age estimate of max heart rate, which is rough and varies between people — use the talk test as the real check.
