How do I actually follow this HIIT 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.

Power-endurance climbing intervals

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

Use the research-backed prompt on this page: "Write me a 25-minute power-endurance interval session for an intermediate climber that mimics sustained climbing efforts. I have a fingerboard, pull-up bar, or a wall I can do laps on. Warm-up (6 min): easy movement, arm…" Copy the full version with the button above — it wraps the request so ChatGPT, Claude or Gemini returns a clean, followable HIIT 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).

Write me a 25-minute power-endurance interval session for an intermediate climber that mimics sustained climbing efforts. I have a fingerboard, pull-up bar, or a wall I can do laps on. Warm-up (6 min): easy movement, arm swings, 2 sets of 8 scapular pull-ups, then 2 short easy climbing or pull-up bursts to raise heart rate. Main set: 6 intervals of 45 seconds of hard, continuous work (climbing laps, repeaters on a hangboard, or pull-up/row combos) at an effort where my forearms build a strong pump and heart rate is in zone 4 (roughly 85-90% of max HR), followed by 75 seconds of easy rest. Tell me how to judge the right intensity, what to do if my grip fails before 45 sec, and how to scale up or down. Cool down 3 min with easy movement and forearm stretches. Note that this is demanding on the fingers and to skip it if my hands are already fatigued or sore.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Short, hard intervals with incomplete recovery train the ability to repeat efforts under fatigue, which is what 'power endurance' means on the wall. The interval format is grounded in the cited training research, but those studies used cycling/running, not climbing — the local forearm pump that limits climbers isn't the same as whole-body aerobic fatigue, so treat the carryover as plausible rather than directly proven. Keep finger load conservative when fatigued.
