How do I actually follow this cycling 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.

Low-impact spin to add aerobic volume

Q: What is the best ChatGPT prompt for a cycling workout like this?

Use the research-backed prompt on this page: "Give me a 45-minute steady Zone 2 cycling session (indoor trainer or flat road) for an intermediate runner using this as low-impact cross-training. Structure: (1) Warm-up: 5 min easy spinning, cadence ~85-95 rpm, gradual…" Copy the full version with the button above — it wraps the request so ChatGPT, Claude or Gemini returns a clean, followable cycling 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 45-minute steady Zone 2 cycling session (indoor trainer or flat road) for an intermediate runner using this as low-impact cross-training. Structure: (1) Warm-up: 5 min easy spinning, cadence ~85-95 rpm, gradually lifting effort. (2) Main: 35 min held in Zone 2 - that's roughly 65-75% of max heart rate, an easy-conversational pace where I could speak in full sentences. If I'm using power or RPE instead of HR, keep me at about RPE 3-4 out of 10. Keep cadence relaxed at 85-95 rpm and remind me to back off if my HR drifts above Zone 2. (3) Cool-down: 5 min easy spin winding down. Tell me to keep it genuinely easy - the goal is aerobic volume with no pounding, not a hard effort - and note this is a good option on a day between hard runs or as an extra aerobic session without adding running mileage.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Easy Zone 2 work builds aerobic capacity and is the bulk of training in the polarized/80-20 model that endurance research supports. Cycling lets a runner add this low-intensity volume without the impact load of more running, which can help manage cumulative leg stress - though cross-training transfers imperfectly and is a complement to running, not a full substitute for run-specific volume. There is no special 'fat-burning zone'; the value of Zone 2 is aerobic base and recoverable volume.
