Whether you teach yoga, run a 24/7 gym, manage a CrossFit box, or coach 1-on-1 personal training, Gym Builder lets you set up your weekly timetable, let visitors register for a class right from the timetable (free — no add-on needed), manage trainers + members, show membership packages, and grow your fitness business — without touching a line of code.

⭐ Why Choose Gym Builder?

Ready in about a minute — a short setup wizard asks what you teach, then builds your classes, trainers, pricing plans, a timetable page and a pricing page for you (sample or your own), so you start with a working site instead of an empty one
Free class registration — visitors register for a class straight from the timetable, see how many places are left, and pick a plan; no paid add-on needed
Built for fitness businesses — every field, taxonomy, and workflow is purpose-built for class/trainer/member operations, not a generic booking plugin
Works with any WordPress theme — Astra, Hello Elementor, GeneratePress, OceanWP, Kadence, Twenty Twenty-Four, Twenty Twenty-Five, and most block themes
No-code admin — modern React-based dashboards; no developer required
Speaks your members’ language out of the box — ready-made translations for Italian, German, French, Dutch, Polish, Spanish and Mexican Spanish, across the free plugin and every Pro add-on; switch your site language and the whole suite follows, with no translation work at all
Lightweight & fast — optimized for site performance, minimal frontend asset load
GDPR-friendly — member data stays on your site, nothing sent to third parties unless you opt in
Theme-overridable templates — override any frontend template by placing a file in your-theme/gym-builder/

Logged-in members add classes to their own membership, within their plan’s classes, class count and end date
Picking a plan a member doesn’t hold yet becomes a plan request the gym approves or dismisses

⏳ Class Waitlist

Join the Waitlist on any full class time — visitors with their name, email and phone, members with one click
A place that opens is held for the next person for the hours you choose and offered by email with a Claim Your Place button; nobody else can take it meanwhile
Members can add the class to their plan, or ask to swap one of their class times for it; you approve the swap
Places of ended memberships (optional): a member whose membership ended is warned, and if they don’t renew in time their place goes to the people waiting
A Waitlist page in the Dashboard: who is waiting, places held, swap requests, figures for any dates, and buttons to offer a place, move someone in line, remove them or add someone by hand
Members see their lines and any place held for them on their dashboard; every step sends its own email
Works with Tools Export / Erase Personal Data, and with the Pro add-ons: Stripe, Offline Payments, Class Booking and Payment, the Registration Popup, the Class Routine block and widget, Attendance and the AI Agent
Off until you switch it on (Settings Classes Waitlist); needs multi-class memberships

🚀 Pro Add-ons & Themes

Everything above is free. When you are ready to take money, track who turns up, or build pages faster, each add-on plugs straight into the classes, plans and members you have already set up — install only the ones you need, or take the whole Pro Bundle. Every add-on below ships the same seven ready-made languages as the free plugin, so adding one never leaves an English patch in a translated site.

🤖 Pro Add-ons — Running the Studio

🤖 GB AI Agent
Run the gym by chatting. Ask it to create a trainer, add a class with its weekly timetable, build a membership package and its class-access rules, enrol or deactivate a member, or free up seats — it checks capacity against the real schedule before it books anything. It configures Stripe for you (keys, billing intervals, prices, and the push to Stripe), assembles a draft Elementor page from section presets or imports a niche template, and pulls reports on the fly: today’s classes, members, expiring memberships, overdue payments, revenue, attendance, personal sessions and workout engagement — exportable as PDF, Word or Excel. It also emails members for you (renewal reminders, or a nudge to the ones who stopped logging workouts), sends you a weekly digest, and answers “how do I…” questions from the family’s own documentation with the exact admin path. Anything destructive asks for confirmation first, nothing changes until you approve it, and every action it takes is listed in an activity log.

Needs WordPress 7.0 or newer — it is built on the WordPress Abilities API and AI Client — plus an AI provider plugin (OpenAI, Anthropic or Google) with your own API key under Settings AI.

💰 Pro Add-ons — Getting Paid

💳 GB Stripe Payments
Stripe Checkout for your membership packages. Five billing intervals — monthly, bi-monthly, quarterly, yearly and one-time — with the buyer choosing their class day and time at checkout and seat capacity checked before the payment goes through. Webhook automation activates the membership the moment payment clears, keeps member status in sync on renewal, failure and cancellation, supports several subscriptions per user, and clears stale states with a daily cron. Subscriptions admin screen with CSV export. When a renewal payment fails, the gym is emailed and the member keeps their place for the grace days you set; pausing a membership moves the next payment later.

🏦 GB Offline & Manual Payments
Card is not how every studio gets paid. The customer picks “Bank transfer” or “Pay at the studio” at checkout, sees your payment instructions and a reference to quote, and their class place is held while they pay. The order waits in a queue in your admin; when the money arrives you approve it and the membership activates exactly as a card payment would. Covers plans bought from the pricing table, payments recorded by hand at reception, personal session bookings and registrations taken through the popup. Runs alongside GB Stripe Payments, so the same plan can be paid either way.

🎁 GB Promotions & Trials
Coupons, discount codes and free trials for your memberships. Percentage or fixed discounts with usage limits, expiry dates and per-plan targeting, plus an analytics dashboard showing redemptions, discount given, revenue driven and which member used which code. Gateway-neutral by design — Stripe today, with PayPal and Razorpay ready behind a documented interface.

📆 Pro Add-ons — Bookings & Attendance

🗓️ GB Personal Session
One-to-one private training alongside your group classes. Calendar-based slot management with bulk scheduling, a multi-step booking widget (trainer date time details pay), guest booking with no WordPress account needed, Stripe payment, twice-daily email reminders, refunds at a configurable percentage, trainer reviews with manual or automatic approval, Google Calendar sync, CSV export, and a full status workflow (pending confirmed completed, plus cancelled and no-show). Adds its own tabs to both the member and trainer dashboards.

📊 GB Attendance System
Check members in at the front desk, let them check themselves in from their dashboard, or have them scan a QR code poster with their phone. A front-desk kiosk on a tablet checks members in with their code or member card. Haven’t Been In lists members who stopped coming and emails them to come back. Attendance Report gives you an overview across the studio and a drill-down per member, with a printable individual report.

📋 GB Registration Page Popup
An auto-shown registration overlay on any page, in three layouts, with a per-class scheduling launcher, profile photo upload, reCAPTCHA, and its own email settings. Paid registration runs through Stripe or Offline Payments.

📅 GB Zoom Integration
Run classes online. A per-slot Online / Offline toggle with Meeting ID, URL and password on each time slot, public class-type badges in your own wording and colours, and a Get Zoom Class Link button on …
