WhatsApp AI agent for gyms and fitness studios: answer membership questions and book the trial class

Fitness leads are impulsive. Someone decides at 9pm on a Sunday to finally join a gym, messages three, and joins the one that answers. The coach is on the floor, the front desk closed at 8, and the message waits until Monday, by which time the impulse is gone. An AI agent answers in seconds and books the trial while the motivation is still there.

Quick answer

Give your gym a WhatsApp AI agent that answers membership prices, class schedules, trial offers and location, books trial sessions into real class slots, and nudges leads who go quiet. Keep injury and medical questions, contract disputes and cancellations with staff. ReplyKit sets this up in about 15 minutes for $29 a month.

The 9pm decision

Nobody joins a gym at a convenient time for the gym. They decide late at night, after a bad photo, before a holiday. The window is short and the competition is one tap away. Response-time research such as the Lead Response Management study puts the best odds inside five minutes. A studio that replies Monday morning is replying to someone who has already booked a trial elsewhere or talked themselves out of it.

What the agent handles

Automate

  • Membership options and prices, joining fees, freeze and cancellation terms as written in your policy.
  • Class schedule by day, level and instructor, from your timetable.
  • Trial class or free-session booking into real slots, with a reminder the day before.
  • Location, parking, opening hours, what to bring, shower and locker facilities.
  • Beginner questions: "I have never done yoga, which class?" answered from your own guidance.
  • Personal training availability and rates.
  • One polite follow-up if a lead goes quiet after asking about a trial (Growth and Pro plans).

Keep with a person

  • Injuries, pregnancy, medical conditions and whether a class is safe for someone. Always a person.
  • Contract disputes, refunds, freezes outside the written policy.
  • Complaints about staff or members.
  • Corporate and group deals.

Booking the trial while the motivation lasts

Set each trial-eligible class as a service with its day and time, and cap the number of trial spots per class. The agent offers the next real sessions, books one, confirms what to bring, and reminds the lead the day before. The booking lands in the leads list as Booked, and after the session the front desk marks it Won or Lost with a reason, so you learn whether it is price, timing or the class itself that loses people. Our guide on reducing no-shows covers the reminder wording.

Setup for a studio

  1. Use a dedicated number. ReplyKit connects your number through Meta's official WhatsApp Business Platform: keep the number you already use in the WhatsApp Business app and the agent works alongside it, or add a dedicated number. Personal WhatsApp numbers cannot be connected. Keep your long-standing number out of it; details in Meta's messaging limits explained
  2. Paste your website and upload the timetable and price sheet as PDFs. Write membership terms as plain text in the words you use at the desk.
  3. Add trial classes as services with days, times and capacity. Set opening hours.
  4. Instruct the boundaries: medical questions to a person, no discounts beyond the published ones, always offer a trial.
  5. Connect the number through Meta's sign-in and test as a nervous beginner asking whether a class is safe with a bad knee. It should hand over.

A worked week at a boutique studio

About 150 WhatsApp enquiries a week, two thirds outside desk hours, most asking for the schedule and a trial. Before: replies the next morning, roughly 40 percent of trial requests never turn into a booking. After: replies in seconds, trials booked into the next sessions, one nudge to the ones who went quiet, and staff handle the medical questions and the two contract queries handed over. Around 200 replies a month, comfortably inside Starter, though studios that want the follow-up nudge sit on Growth.

Frequently asked questions

Can the agent book a trial class?

Yes. Set trial classes as services with times and capacity; it offers real sessions, books one, sends a reminder and records the lead as Booked.

Will it answer medical or injury questions?

No. Instruct it to hand those to a person, and it will. ReplyKit's terms also prohibit configuring regulated advice.

Does it follow up with leads who go quiet?

On Growth and Pro plans it sends one polite nudge if a lead stops replying after the agent asked something. Never more than once.

Can it handle membership sign-ups?

It explains options and collects name, contact and preferred plan, then hands over or books an in-person visit. Payment and contracts stay with your existing system.

How much does it cost?

From $29 a month for one number and 1,000 replies. The follow-up nudge is on the $49 Growth plan. 7-day free trial with 300 replies included.

Book the trial at 9pm, not Monday

Upload your timetable, add trial classes, connect your number through Meta's sign-in. 7-day free trial.
