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.

Who is this workout for, and who should adapt or skip it?

Built with one person in mind: 30s, getting back into it, fat loss and energy, no gym needed. The jumping and high-impact work isn’t ideal if you’re pregnant, managing a heart condition, or nursing a knee, hip or ankle issue, swap in the low-impact variations or choose a steady session instead.

The prompt

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

Write me a 15-minute beginner HIIT session I can do at home with no equipment. Use 20 seconds of work then 40 seconds rest, 8 to 12 rounds, with simple low-to-moderate-impact moves like marching high knees, step-ups, fast bodyweight squats and modified jacks. Keep the work hard for me but the rests generous, and tell me to build the intensity over the weeks. Build it as timed rounds and list each move in order with its work and rest in seconds.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Even short, low-volume intervals build fitness efficiently, a generous 1:2 work-to-rest ratio keeps it doable for a beginner while you raise the intensity over time.

Who this workout is for

Built with one person in mind: 30s, getting back into it, fat loss and energy, no gym needed.

You’re a beginner-level trainer and you want to lean out while keeping strength.
You want to train with little or no equipment, this one needs none, bodyweight.
You want a single, repeatable HIIT workout you can drop into your week.

Who should adapt or skip it

The jumping and high-impact work isn’t ideal if you’re pregnant, managing a heart condition, or nursing a knee, hip or ankle issue, swap in the low-impact variations or choose a steady session instead.
As with any new routine, check with a clinician first if you have a medical condition, are injured, pregnant, or returning from a long lay-off. This is general information, not medical advice.

What a 2-week plan looks like

A single session works best on a repeating weekly rhythm. Here’s a simple, balanced two-week block at about 2 sessions a week, on non-consecutive days so you recover between them:

	Mon	Tue	Wed	Thu	Fri	Sat	Sun
Week 1	●	·	·	●	·	·	·
Week 2	●	·	·	●	·	·	·

● This session· Rest or easy aerobic work

Keep session days apart where you can, and adjust for how you feel. When you paste the AI’s reply into sweatcue, each session runs hands-free with spoken cues and timers.
