How to write Instagram captions as a fitness coach that don't sound like AI. 12 rules, 10 rewrites and the prompts that use your own voice.

When to use it: You have the caption body and the first line still sounds generic.

What to paste in: The caption body plus the specific detail it is built on.

Write 8 possible first lines for this Instagram caption. Each line must name the specific thing in the post, not the theme. No rhetorical questions, no "ever feel like", no "here's the truth". At least 3 must start with a number or a name. At least 2 must be under 6 words. None may be reusable for a different post.

The post: [PASTE THE CAPTION BODY]
The specific detail: [CLIENT / NUMBER / MOMENT]
My usual opener style, from my own captions: [PASTE 2 OF YOUR OWN FIRST LINES]

Output the 8 lines only, numbered, no commentary.

When to use it: A personal story or a moment from coaching that makes people follow the person.

What to paste in: The story in your own rough words, including the part that went wrong.

Turn my rough notes into an Instagram story caption in my voice. Keep it in first person, past tense, concrete. Start inside the moment (a time, a place, a sentence someone said), not with "let me tell you a story". Keep the part that went wrong; do not soften it. No moral at the end, no "the lesson here is". End on the last concrete thing that happened or on one line that connects it to a client this week. 100 to 180 words. No lists of three. No emojis unless my samples use them.

My rough notes: [PASTE YOUR NOTES, MESSY IS FINE]
Two captions I wrote before, for rhythm: [PASTE]
Words I never use: [PASTE]

When to use it: An offer or spots-open post where the ask has to be clear without sounding like a sales page.

What to paste in: What the offer actually is, the price if you share it, the start date, and the one action.

Write an Instagram caption that opens spots for my coaching. The rule: describe the thing, then ask once. No "limited spots", "don't miss out", "ready to transform", "take it to the next level". Say exactly what a client gets, in plain words, as if I were explaining it to a friend on the phone. Include the start date and the number of places if I gave them. One ask on the last line, using the exact keyword I give you. 70 to 120 words.

What the coaching includes: [YOUR LIST IN PLAIN WORDS]
Start date and places: [e.g. October, two places]
Price, if shown: [e.g. EUR 180 a month, cancel monthly / do not mention]
The keyword to message: [e.g. OCTOBER]
Two captions I wrote before: [PASTE]

When to use it: An educational carousel where the slides carry the content and the caption sells the swipe.

What to paste in: The 5 to 8 points, one line each, and which one is the most surprising.

I am posting a carousel. Write (a) the slide text and (b) the caption.

Slides: one idea per slide, maximum 14 words per slide, slide 1 is the title as a plain statement (no "5 secrets", no "you need to know"). The most surprising point goes on slide 2. Last slide is one plain ask.
Caption: 2 to 4 lines. Name what is on slide 2 specifically so people have a reason to swipe. No "swipe to discover", no "save this so you never forget", no emojis unless my samples use them.

My points: [PASTE 5 TO 8 POINTS]
The most surprising one: [WHICH]
The ask on the last slide: [e.g. save it / message me the word PLAN]
Two captions I wrote before: [PASTE]

When to use it: The video carries the content and the caption has to do one job in one to three lines.

What to paste in: What happens in the video, who it is for, and the cue or point.

Write 5 alternative captions for this reel, each 1 to 3 lines. The video already shows the content, so the caption names what it is and who it is for, in the words I would use to a client. No "this will change your life", no "try this", no "follow for more". At least 2 versions include the exact cue or number from the video. Hashtags: [none / N on a separate last line].

What happens in the video: [DESCRIBE]
Who it is for: [e.g. anyone whose lower back rounds in a deadlift]
The cue or number: [e.g. "push the floor away", 10 reps]
My usual tone, two captions I wrote: [PASTE]

When to use it: A client hit a milestone and has agreed in writing that you can share it.

What to paste in: Only the details you have permission for: first name or "a client", the timeframe, the number, one thing that went wrong, and one line they said.

Write a client-win caption. I have the client's permission to share exactly what I paste below and nothing else; do not add details, do not invent a quote, do not describe their body. Structure: the specific result with the number, then the part that was hard or went wrong, then one line in the client's own words (verbatim from what I paste), then one line about what we actually changed in the plan. Finish with "Shared with [first name]'s permission." and, if I give one, one ask. 90 to 150 words. No "incredible", "amazing", "proof that", "anything is possible".

Client: [FIRST NAME or "a client"]
Timeframe and result: [e.g. 11 weeks, first unassisted pull-up]
What went wrong along the way: [e.g. missed two weeks in month two]
Their words, verbatim: [PASTE THE LINE THEY SAID OR WROTE]
What I changed in the plan: [ONE SPECIFIC THING]
The ask, if any: [e.g. message me PULLUP / none]
Two captions I wrote before: [PASTE]

When to use it: You keep hearing the same wrong belief from clients and want to correct it without lecturing.

What to paste in: The myth, what you actually see in clients, and one real example with a number.

Write a myth-bust caption that never uses the words "myth", "bust", "truth" or "let's debunk". Start with the real situation, not the myth: what a client did because they believed it, with a number. Then what actually happened when we changed it. Then the plain explanation in two sentences a client would understand. No "in fact", no "the science says" unless I paste a specific source. End on the practical instruction, not a moral. 80 to 140 words.

The belief: [e.g. carbs after 6pm turn to fat]
What I see clients do because of it: [SPECIFIC EXAMPLE WITH A NUMBER]
What changed when we fixed it: [SPECIFIC]
Plain explanation: [YOUR TWO-SENTENCE VERSION]
Two captions I wrote before: [PASTE]

When to use it: A behind-the-scenes post that shows the unglamorous work instead of the highlight reel.

What to paste in: Your actual timeline for the day, including the boring parts, and one client situation you handled (anonymised).

Write a day-in-the-life caption from my actual timeline. Use the real times. Include the boring parts and at least one thing that did not go well. Pick one client situation from my notes and show the decision I made, in one or two sentences, without naming or describing the client. No "busy but blessed", no "grateful", no "hustle", no sunrise emojis. It should read like a diary line, not a brand post. 80 to 140 words. End on the last thing that happened, not a reflection.

My timeline today: [PASTE, e.g. 06:10 own session, 07:30 check-ins, ...]
One client decision (anonymised): [e.g. sleep dropped to 5 hours, cut plan from 4 to 3 sessions]
What went badly: [e.g. my own session, skipped the last set]
