The prompt

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

I'm a beginner with one pair of adjustable dumbbells at home and want a 22-minute HIIT conditioning session built from dumbbell complexes. Warm up for 4 minutes with light jogging-in-place, bodyweight squats, and arm swings. Then give me a circuit of 3 movements done back-to-back without putting the dumbbells down: dumbbell thruster, single-arm dumbbell snatch (alternating), and renegade row. Use a work/rest structure of 40 seconds work, 20 seconds rest per movement, complete the 3 as a round, then rest 60 seconds between rounds; do 5 rounds. Use a light-to-moderate weight I can move with good form when fatigued, and have me aim for an effort where my heart rate climbs into roughly 80-90% of max during work intervals. Give a regression for each move if my form breaks down, and finish with a 2-minute cool-down walk and stretch.
Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Short, hard interval circuits like this raise aerobic fitness and can improve body composition in limited time, and bodyweight or light-load HIIT is an established time-efficient format. The catch is honest: this is demanding and form on complex lifts decays under fatigue, so beginners should keep loads light and stop a set if technique slips. It builds conditioning, not maximal strength.

Who this workout is for

Built with one person in mind: Just a pair of adjustable dumbbells, complete full-body programmes at home.

  • You’re a beginner-level trainer and you want to build visible muscle.
  • 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:

● 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.
