How to build a WhatsApp chatbot for a gym (2026, free to start)
You need your membership prices and your class timetable, a WhatsApp number on a phone you control, and about ten minutes.
Building and testing the bot is free with a 30 message demo and no card; putting it on WhatsApp runs on the Starter plan at US$29 a month, which opens with a 7 day trial.

What this bot does for a gym
Five jobs it takes off your team, with the kind of exchange you will actually see in the transcript.
Sells memberships at the moment somebody decides
People decide to join at 10pm on a Sunday. It answers the price, the joining fee and what is included, then takes their details so your team calls a warm lead on Monday.
Customerhow much is it a month
BotMonthly is 45 with no commitment, or 38 a month on a twelve month plan. There is a 25 joining fee, waived if you start on a twelve month plan. Both include all classes, the sauna and the app.
Answers class timetable questions instantly
Which class, what time, with whom, and whether it needs booking. The timetable question arrives dozens of times a week and the answer never changes between updates.
Customeris there spinning on tuesday evening
BotYes, spinning on Tuesday at 7:00pm and 8:15pm with Marta. Bikes are booked through the app and open 48 hours in advance. Tuesday 7pm usually fills, so book early.
Hands out trial passes and books the first visit
It explains what the trial covers, collects a name and number, and books a slot with a trainer. The pass stops being a coupon nobody redeems.
Customercan i try before i sign up
BotYes, a free three day pass with full access to the floor and classes. I need your name, a number and an email to issue it. Do you want a free induction with a trainer on your first visit? Most people take it.
Answers hours, facilities and access questions
Opening times, the pool, parking, whether the changing rooms have lockers, whether the 24 hour access is real. The details that decide between you and the gym two streets away.
Customerwhat time do you open on sundays and is there parking
BotSundays we open 9:00am to 3:00pm. Weekdays it is 6:30am to 11:00pm. Parking is free for members in the underground car park for up to two hours, with a plate reader at the barrier.
Explains freezes and cancellations honestly
The questions members most resent asking. It gives the real terms and routes the request to a person, which keeps the conversation off your review page.
Customeri want to cancel my membership
BotThat is handled by our team so we can check your contract date. Monthly memberships need 30 days notice and can be cancelled any time; twelve month plans can be frozen free for up to two months instead. Can I take your name and I will have someone call you today?
Build it in eight steps
Steps one to five are free and take about ten minutes. Step six is where WhatsApp, and the plan, come in.
Create the account
Open chatbotgen.com and sign up with an email address or a Google account. No card is asked for here, and none is needed for anything in steps one to five.
You should see: The onboarding wizard, open on the template picker.
Pick the Sales Assistant template
Choose Sales Assistant. It loads a starting prompt, three suggested questions and a widget colour written for this kind of business, so you are editing a draft instead of facing an empty box. Every line of it is yours to change.
You should see: A new chatbot in your dashboard with the prompt already filled in.
Train it on material you already have
Open Knowledge and paste your website address; the crawler reads your public pages and turns them into the bot's memory. Then upload the documents you hand people anyway: the membership prices, the class timetable, the trial and cancellation terms, and the facilities list.
You should see: Each source moves from processing to trained. A twenty page site is usually done in two or three minutes.
Write down the answers your website never did
Still in Knowledge, open Q&A and add the questions your staff answers on the phone all day. For a gym that is usually: whether there is a joining fee, how to freeze a membership, whether classes are included, and what the trial pass covers. Two sentences per answer is enough; the model writes the rest in its own words.
You should see: Each pair listed as its own source, trained within seconds.
Test it before anyone else does
Use the preview chat on the chatbot page and ask what a real customer asks. Start with "How much is a monthly membership and are classes included?" Then ask the same thing badly, with a typo and no punctuation, because that is how it will arrive.
You should see: A correct answer with the source it came from. Wrong or vague? Fix the source, not the prompt. Your free demo covers 30 messages, which is enough for this.
Connect WhatsApp by scanning a QR code
Connect your existing WhatsApp number in about a minute by scanning a QR, with no Meta Business verification. Open the chatbot's WhatsApp tab, press Connect, and a QR code appears. On the phone that owns the number, open WhatsApp, go to Settings, Linked devices, Link a device, and scan it. No Meta Business account, no verification form, no approval queue. This step runs on the Starter plan, US$29 a month, opening with a 7 day trial.
You should see: The status flips to Connected within a few seconds, and the next customer message is answered on your own number. Keep that phone charged and online, exactly as it already sits on your counter.
Decide when a person takes over
A person should take over for cancellations, freezes and billing disputes, because those need your member system and a decision. You do not need a dashboard for this. If you answer a customer yourself from the linked phone, the bot records your message, steps back from that conversation for 30 minutes, and each further reply of yours pushes the pause forward. It resumes quietly, without announcing itself.
You should see: Your own replies appearing in the conversation history in the dashboard.
Go live, then read the first fifty conversations
Put the number on your website, your Google Business profile and your Instagram bio. Then read the transcripts. Every question the bot did not have an answer for yet is one Q&A pair away from being answered forever, and the first week is where the whole quality of the thing gets decided.
You should see: A Conversations tab filling up, and a growing share of messages answered end to end without you.
What to feed it
A bot is only as good as the material behind it. These are the sources that answer the most messages for a gym, in the order worth doing them.
Membership prices and terms
Every plan, the joining fee, what is included, and the notice period. Include student, couple and off-peak rates if you have them.
The class timetable
Class, day, time, instructor, whether booking is required. Re-upload whenever the timetable changes, which for most gyms is quarterly.
The trial offer
What it covers, how long it lasts, whether an induction is included, and how somebody redeems it.
Freeze and cancellation policy
The exact terms per plan. Being straight about this in the chat prevents most of the arguments it would otherwise cause.
Facilities and hours
Pool, sauna, free weights, parking, lockers, staffed hours versus access hours, and holiday timetables.
Personal training and extras
Prices per session and per pack, which trainers, and how to book.
Set it up so customers trust it
Three settings that separate a bot people keep writing to from one they stop trusting. Each is a line in the prompt, and each one is a minute of work.
Route these to your team
- Route training, nutrition and injury questions to a trainer or a physiotherapist.
- Let your team action cancellations and freezes. The bot captures the request with the member's name, so you get the retention call in while they are still reachable.
- Keep payments in your own sign-up flow.
- Let your app hold class bookings. The bot tells members what is on and how to book it.
It answers in your customer's language
It replies in the language the enquiry arrives in, across the thirteen the model handles well. For a gym in a city with a large international population, that is a wider catchment for the same shopfront.
Hand the conversation to a person when
- Cancellations, freezes and anything about a charge on a card.
- Any injury, pain or medical question, without exception.
- Corporate memberships and group deals, which need a negotiation.
What people ask before they build one
Can it take payments and sign people up?
It answers, qualifies and collects the details, and your team closes in your own payment flow. That is the right split: on WhatsApp, a chat asking for card details is what a scam looks like, so keeping the sign-up in your own flow is what makes members finish it.
Do I need a Meta Business account or the official WhatsApp API?
No. You connect by scanning a QR code from the phone that owns the number, the same way WhatsApp Web does. There is no Meta Business verification, no approval queue and no per-message fee.
The timetable changes. How much work is that?
One upload when the timetable changes, and a deletion of the old one. That is the entire maintenance. The failure mode is not a changing timetable, it is a bot still quoting the spring schedule in October.
What does it cost to run?
Building and training the chatbot is free, with a 30 message demo to test it and no card. Connecting WhatsApp is on the Starter plan: US$29 a month for 3 chatbots and 2,000 messages, opening with a 7 day trial that does ask for a card. Prices are flat, not per message.
Will it help with people who are about to quit?
It gives you the early signal, which is what you do not have today. A cancellation message arriving at 11pm gets an honest answer about freezing instead of silence, and a named person calls the next morning while the member is still reachable.
What happens when I answer a customer myself?
The bot gets out of the way. Your reply, typed on the linked phone, is recorded in the conversation and the assistant stops answering that thread for 30 minutes; every further message from you pushes the pause forward. It starts answering again quietly once the conversation has gone cold, so it can never talk over you mid-sentence.
Build it now, decide later
The Sales Assistant template, your own material and ten minutes. Nothing to install and no card for the free build.
