The prompt

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

I'm a beginner training at home with only adjustable dumbbells. Write me an 8-week dumbbell-only muscle-building plan on an upper/lower split, 4 days a week (Upper A, Lower A, Upper B, Lower B), each session about 45 minutes. Every session opens with a 5-minute warm-up. Upper days use floor/bench press, shoulder press, single-arm rows, flyes, lateral raises, curls, and triceps extensions; lower days use goblet squats, Romanian deadlifts, reverse lunges, calf raises, and a core hold. Prescribe 3 sets of 8-12 reps per exercise at an RPE of 7-8 (2-3 reps in reserve), with 90 seconds rest. Build in progression: each week, when I can complete all sets at the top of the rep range with 2 reps to spare, add a small load increase or one more rep, and include a lighter deload in week 5. Give me the weekly schedule as a table plus simple rules for when to add weight.
Works with Claude, Gemini, Grok or any AI.

Why it's built this way

Training each muscle about twice a week, accumulating around 10 or more hard sets per muscle weekly, and progressing load or reps over time are the well-supported levers for building muscle as a beginner. An upper/lower split delivers that frequency in four sessions, and stopping 2-3 reps short of failure captures most of the growth while keeping technique safe at home.

Who this plan 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 structured, progressing plan rather than a one-off session.

Who should adapt or skip it

  • It’s low-risk for healthy adults. Scale the loads and reps to your own level rather than copying the top of every range on day one.
  • 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

This is a multi-week plan that progresses as you go, the AI builds the later weeks harder. Here’s the rhythm of the opening fortnight, at about 4 sessions a week:

Week 2●●·●·●·

● This session· Rest, a walk, or light mobility

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.
