How to write the perfect workout prompt

The four layers

Every strong prompt has four parts. Drop one and the plan fails in a way you can predict:

• Context: who you are and what you've got. Skip it and the plan is generic.
• The ask: the goal, scope and style. Skip it and it's unfocused.
• The format: how to lay the answer out. Skip it and you get a wall of prose you can't train from.
• The loop: how it should change over time. Skip it and a multi-week plan goes nowhere.

1. Context: the five things to always tell it

The AI can't see you, so it only knows what you put in. Give it these every time:

• Your goal: strength, muscle, fat loss, a faster 10k, a Pilates core routine, more mobility, or a specific event. Lead with one.
• Your experience: new, returning, or years in. This sets sensible volume, pace and exercise choice.
• Days and time: how many days a week and how long each session.
• Your equipment: full gym, dumbbells at home, bands, a reformer, a mat, or just a pair of running shoes.
• Your limits: injuries, conditions, anything to train around. This one keeps the plan sensible for you specifically.

If you care about progression, add your current numbers too: working weights, recent rep counts, bodyweight, your easy and threshold paces, how long you can hold a plank. Then increments start from reality instead of a guess.

2. The ask: be specific about scope

Say whether you want one session, a single week, or a multi-week plan, and name the style if you have a preference: full-body, push-pull-legs, upper-lower, interval and tempo runs, a vinyasa flow, a mat Pilates circuit. Mention what you like and won't do ("compound lifts please, no running"). It also helps to give the model a role to focus it: "Act as a running coach," or a strength, mobility or Pilates one.

3. The format: the part everyone forgets

This is what separates a plan you follow from a plan you abandon. Ask for structure, not prose:

• Every move, exercise or pose on its own line, in the order to do them.
• Sets, reps and rest in seconds, spelled out. For holds and flows, a duration per pose or position instead.
• A load or an RPE per move where it applies. RPE is how hard a set feels out of ten; an RPE 8 leaves about two reps in the tank, which is handy when you don't want to commit to a fixed weight.
• For running and intervals, a duration and a target zone or pace per block.
• No long explanations between moves, just the list. You can ask for the reasoning after.

A clean list beats a paragraph every time, and it happens to be the shape a player can turn into a guided session.

4. The loop: for anything multi-week

A plan that repeats the same week does nothing. Your body adapts to a fixed demand and stalls, so the demand has to creep up. To get real progression, ask for it directly:

• "Show every week separately and tell me exactly what increases, and on which lifts."
• Name the scheme: add a little weight each week, or rotate heavy, moderate and light days. Don't let it decide silently.
• "Include a deload week every four to six weeks." It almost always forgets this.
• Work in four-week blocks, not twelve. The model holds four weeks together and loses the plot over more.
• Close the loop: "After each week I'll paste what I actually did, adjust the next one from that." Now it progresses off real performance.

There's a fuller walk-through in getting ChatGPT to write a plan that progresses.

A template to copy

Here's the whole thing as one prompt. Copy it, fill in the brackets, delete what you don't need, and paste it into ChatGPT, Claude or Gemini.

Act as a [strength / running / mobility] coach.

About me: I'm [a beginner / intermediate / advanced], I train [N] days a week, [time] per session. Equipment: [full gym / dumbbells at home / bands / none]. Goal: [strength / muscle / fat loss / endurance / event]. Injuries or limits: [none / ...].
[Current numbers: squat __ x __, bench __ x __, etc.]

Write me [a single session / a 1-week plan / a 4-week plan].
[For a multi-week plan: show every week separately. Use [linear progression: add ~2.5kg upper, ~5kg lower each week / heavy-moderate-light days each week]. Tell me exactly what changes each week and on which lifts. Include a deload in week 4 at about 60% volume.]

Format the answer as a plain list: every exercise on its own line, in the order I do them, with sets, reps, rest in seconds, and a target weight or RPE. For any cardio, give a duration and a target zone or pace per block. No explanations between moves.

Then do it

Write the prompt well and you'll get a plan that's both good and readable. The last problem is doing it: a clean list is still a chore to follow from a phone, scrolling between sets and timing rests in your head.

That's the job sweatcue does. Paste the workout your AI wrote and it becomes a guided dashboard, with timers that start themselves and every set, rest and rep called out loud, hands free. The format this guide tells you to ask for is exactly what sweatcue reads. Write it well, paste it in, train.
