ChatGPT Prompts for Fitness Class and Course Descriptions

To write a better fitness class description with ChatGPT, explain what you offer, who it is for, what happens during the session and how the description should sound. Clear context and instructions usually produce a more relevant first draft than simply asking ChatGPT to write a class description.

Introduction

Writing class and course descriptions can be surprisingly difficult.

You understand what happens during your sessions, but a potential client may not. They need a clear explanation of the experience before deciding whether it suits their goals, fitness level and preferences.

ChatGPT can help you create a first draft, improve an existing description or adapt the same information for different audiences. The quality of the result will depend heavily on the information included in your prompt.

Why Fitness Class Descriptions Matter

A useful description helps a potential client answer questions such as:

• Is this class suitable for beginners?
• How intense is the session?
• What exercises will we do?
• Do I need to bring equipment?
• Is this one session or a structured course?
• What level of fitness or experience is required?

A Pilates beginner, an experienced strength trainee and someone considering a six week bootcamp will look for different information.

OpenAI recommends clearly defining the task, providing relevant context and explaining the desired output when prompting ChatGPT.

For a fitness business, this means including details about the client, class format, intensity, equipment, session structure and any important requirements.

What to Include in Your ChatGPT Prompt

Before asking ChatGPT to write your description, collect these five details.

1. The service - Explain whether you are describing a HIIT class, personal training session, yoga class, Pilates programme or fitness course.
2. The target client - Describe who the service is designed for, such as beginners, experienced clients, older adults, athletes or people returning to exercise.
3. The experience - Explain what happens during the session, how it is structured and what equipment is used.
4. The practical information - Include the duration, location, required experience and anything clients should bring.
5. The writing requirements - Tell ChatGPT the preferred length, tone and format. You should also state which claims or details it must avoid.

Research into Requirement Oriented Prompt Engineering suggests that clearly explaining complete requirements can help an AI system produce an answer that better matches the user’s intentions.

Generic Description Compared With a Useful Description

Generic Description

A fun and exciting HIIT class that will transform your fitness and help you achieve amazing results.

This description sounds positive, but it does not tell the reader what the session involves or whether it is suitable for them. It also makes broad claims that may not be appropriate.

More Useful Description

A 45 minute coached interval class combining bodyweight exercises, kettlebells and short cardio sections. It is designed for adults with some basic exercise experience, with easier and harder variations provided where appropriate.
Expect a structured warm up, several coached work intervals and a short cool down. Bring water and wear comfortable training shoes.

The second version provides information the client can use when deciding whether to book.

Common ChatGPT Prompting Mistakes

Providing Too Little Information

Asking ChatGPT to make a description sound better does not explain what better means.

Include the audience, service details, tone, length and purpose.

Using the Same Prompt for Classes and Courses

A class description focuses on one session or a recurring session.

A course description should also explain the number of sessions, programme structure, progression and what participants will work on over time.

Allowing ChatGPT to Invent Details

ChatGPT may add equipment, qualifications, benefits or session features that you did not provide.

Tell it not to invent information, then check every detail before publishing.

Using Unsupported Claims

Avoid statements that promise guaranteed weight loss, pain relief, improved health or specific physical results.

Describe the experience you provide rather than promising an outcome you cannot guarantee.

Publishing the First Response

The first answer should be treated as a draft.

Ask for a clearer, shorter or more welcoming version. You can also combine the strongest parts of several drafts.

Removing Your Own Voice

A description should still sound like your fitness business.

Add phrases you naturally use with clients and remove wording that feels overly formal, exaggerated or generic.

Step by Step Process

1. Write down the facts about the class or course.
2. Identify the type of client it is designed for.
3. Add the information to the relevant prompt template.
4. Ask ChatGPT for one clear version and one more energetic version.
5. Compare the drafts and keep the most useful wording.
6. Check every duration, requirement, price and service detail.
7. Remove exaggerated or unsupported claims.
8. Add details that reflect your real coaching approach.
9. Read the description from the perspective of a new client.
10. Publish it where clients view and book your services.

BookFit can help fitness professionals manage classes, courses, bookings, clients, payments, memberships, packages, vouchers, reminders and client accounts.

Your class description should still be based on your own knowledge of the service and client experience you provide.

Key Takeaway

A good ChatGPT prompt does not need to be extremely long.

It needs to give ChatGPT the facts and requirements necessary to produce the right type of description.

Start with the service, target client, session experience and practical details. Specify the desired length and tone, then review the result as an experienced fitness professional.
