Sweet-spot intervals
Intermediate · 40–54 · ~60 min
Big aerobic stimulus you can repeat — the workhorse of FTP building. Below is a research-backed prompt for ChatGPT, Claude or Gemini — copy it, paste the reply into sweatcue, and run the whole cycling workout hands-free.
Session at a glance
This is how sweatcue structures the session once you paste it in — timed blocks with auto-starting rest and spoken cues. Figures are read from the prompt itself.

Why it's built this way
Sweet spot — riding just below threshold at roughly 88–94% of FTP — packs a strong aerobic and FTP-building stimulus into efforts you can repeat without long recovery. It's well-established coaching practice rather than lab-proven, so pick one band and progress it; expect your heart rate to drift up at steady power.

Run it hands-free in sweatcue
sweatcue is an AI workout dashboard: paste the AI's reply and it runs the whole session on screen and out loud — auto timers, spoken cues for every set, rest and rep, and your live numbers. The AI writes it; sweatcue runs it.
