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: 40s, busy, all-round fitness that keeps you supple. 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.

No-jump HIIT for busy 40s

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

Use the research-backed prompt on this page: "Build me a 20-minute low-impact HIIT workout I can do at home with no jumping (joint-friendly for someone in their 40s). Structure it as: - 4-minute warm-up: marching in place, arm circles, hip openers, slow bodyweight s…" 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).

Build me a 20-minute low-impact HIIT workout I can do at home with no jumping (joint-friendly for someone in their 40s). Structure it as: - 4-minute warm-up: marching in place, arm circles, hip openers, slow bodyweight squats, leg swings. - Main set: 6 rounds of 40 seconds hard / 30 seconds easy recovery (marching). Rotate through no-impact moves: fast bodyweight squats, reverse lunges, standing knee drives with arm pull-down, squat-to-press with a light dumbbell or water bottle, fast step-backs, and standing punches. Tell me which move goes in which round. - During the 40s hard efforts I should reach roughly 80-90% of my max heart rate (hard, talking only in single words). Recovery should drop me back to a conversational pace. - 3-minute cool-down: standing forward fold, quad stretch, chest opener, each held 30 seconds per side. Give me a simple round-by-round table with the move, the work/rest, and a target effort cue. No burpees, no jumping, no high-impact landings.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Short interval blocks of hard effort improve cardiorespiratory fitness, and bodyweight HIIT circuits are an evidence-backed, time-efficient way to get there, useful when you're busy. Low-impact substitutions (no jumping) keep the intensity without the joint loading; they don't burn fat from any specific area. Higher cardiorespiratory fitness is one of the strongest predictors of lower mortality, so the value here is real but general, not magic.

Who this workout is for

Built with one person in mind: 40s, busy, all-round fitness that keeps you supple.

You’re an intermediate-level trainer and you want a balanced, sustainable routine.
You have access to the kit it calls for: dumbbells.
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.

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.
