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: Teenager starting out, safe, technique-first intro to lifting and conditioning. 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).

I'm a teenager new to exercise and I want a fun, scalable 20-minute conditioning workout using game-style intervals (no equipment, can be done in a yard, gym or living room). Warm-up (4 min): jog in place, high knees, arm swings, 10 air squats. Main (12 min): give me 4-5 playful intervals like 'beat your last round' shuttle touches, 'floor is lava' quick step-ups, animal-style movement bursts, and a 'how many in 30s' challenge, each 30s hard effort then 30-60s easy walk/recover, repeated so total work is about 12 minutes. Tell me to push to roughly 7-8 out of 10 effort (breathing hard but not all-out) on the hard bits and to fully ease off on recoveries, and give a simpler and a harder version of each so I can match my fitness. Cool-down (4 min): walk and stretch. Keep it light-hearted and motivating.

Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Short, intermittent bursts of higher-effort activity broken up by easy recovery are an efficient way to build aerobic fitness, and low-volume interval formats improve fitness in beginners. Making intervals playful and scalable is mainly about adherence and enjoyment rather than a separate proven effect, but for a teenager starting out, the workout you'll actually keep doing is the one that helps.

Who this workout is for

Built with one person in mind: Teenager starting out, safe, technique-first intro to lifting and conditioning.

You’re a beginner-level trainer and you want a balanced, sustainable routine.
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.
It pushes close to heavy or near-failure effort. If you’re brand new to lifting, build technique on lighter sessions first, and skip the near-maximal loading if you have unmanaged blood pressure or a recent injury.
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.
