FITFAC is a Muay Thai academy with 11 gyms across Bangkok and more than 14,000 members. This app is how our members run their training: book a class, check in at the door, see how many sessions are left on your course, and renew it before it runs out. WHAT YOU CAN DO • Book a group class. Pick a branch, a day and a time. If the class is full, join the waitlist and your seat is given to you automatically when someone cancels. • Book a private session. See which Muay Thai coaches and trainers are genuinely free, pick the slot you want, and book it yourself. • Check in when you arrive. One tap at the gym. Check-in confirms you are at the branch using your location. • Know where you stand. Sessions remaining, expiry date, which branches your course is valid at, and every check-in you have ever made. • Renew. Extend your course from the app when it is close to expiring, or message head office to arrange your next package. • Log your weight and body measurements after a session and watch the trend over the months. • Message head office inside the app. Ask about a schedule, a package or a booking and get an answer from a real person, not a bot. • One account for the family. Parents hold their children's courses and book classes for them without logging out. • Reminders before class, and a notification the moment a waitlist seat opens up. VISITING BANGKOK? Travellers train with us every day. Create an account in about a minute, message us in the app with the dates you are free and what you are looking for, and we will set you up at the branch nearest to where you are staying. Our coaches teach in Thai and English, and the app itself is available in 8 languages: English, ไทย, 中文, 日本語, 한국어, Español, Français, Русский. OUR BRANCHES Ari · Rama 9 · Sathorn · Ekkamai · Muang Thong · Rangsit · Liap Duan · Srinakarin · Rachaphruek · Phloen Chit · Taling Chan · DTV NEW TO MUAY THAI? Most of our members had never thrown a punch before their first class. A group class is 90 minutes: warm-up, pad work with a Muay Thai coach, then conditioning with a trainer. You do not need your own gloves or wraps to start, and there is no minimum fitness level. FOR FITFAC STAFF Coaches, trainers and branch teams sign in with a work account to run the day's class list, clock in and out, take payment at the counter and manage stock. Everything sold through this app is a real-world service or item: training sessions at a FITFAC gym in Bangkok, or equipment collected at the gym.
