Rework a gym's brand voice and messaging with ChatGPT for very different client groups

who Bennett Camarda, co-owner of Limitless Fitness, a New Hampshire gym with more than 10 trainers and 150 active one-on-one clients, in CNBC

What it does

They used ChatGPT to revamp the gym's brand strategy, refining its tone, voice and messaging for a client base that runs from strength training for grandparents to performance training for golfers.

The problem

The gym's clients range from grandparents doing strength training to golfers chasing performance, and the new owners wanted a brand tone, voice and messaging that speaks to all of them.

What happened

Camarda says it helped them revamp the brand strategy so it resonates better with their evolving client base, and that trainer and client engagement is at an all-time high since they took over. No marketing figures are given, and engagement isn't credited to AI alone. Self-reported.

How to set it up yourself

  1. What Limitless Fitness did: it used ChatGPT to refine the gym's tone, voice and messaging for its range of clients. The article doesn't give the prompts, so the steps below are our DIY build.
  2. Write down your client groups in plain words (for example older adults starting strength training, golfers, busy parents) and paste in your current website intro and two recent posts.
  3. Run the prompt below in ChatGPT, then ask it to rewrite your homepage intro once per client group in the new voice.
  4. Read the drafts out loud with your trainers, keep the lines that sound like you, and use the agreed voice notes as the brief for every post and email after that.

Copy-paste prompt

I own {GYM NAME} in {TOWN}. Our clients include {CLIENT GROUPS, e.g. grandparents doing strength training and golfers training for performance}. Here is how we sound today: {PASTE WEBSITE INTRO AND 2 POSTS}. Suggest a brand voice in 5 short rules (tone, words we use, words we avoid), then give me one message for each client group explaining why they should train with us, under 60 words each. Don't promise results or use before-and-after language.
