Fitness First Platinum T-One Building ฟิตเนส เฟิร์สท์ แพลตินัม ทีวัน
8 T-One Building, 8th Floor, Soi Sukhumvit 40, Phra Khanong, Khlong Toei, Bangkok 10110
If you train consistently, the zone variety keeps sessions from flattening into routine. The Hot Yoga and Aerial Flow Yoga classes are the standout offerings here. Book through the app 46 hours out. The lounge is worth using between sets when you need to reset. This is built for people who show up five days a week, not casual drop-ins.
You step off the BTS Thong Lo airbridge into the T-One Building lobby. The gym fills the 8th floor. Eleven zones: Freestyle Areas, Mind and Body Studio, Box Studio, Cycling Studio, Group Exercise Studio, Boot Camp Zone, Cardio, Playground, Burn Zone.
The cardio machines line windows that look out over Sukhumvit. Loaded weights and free weights occupy separate zones. The Box Studio has heavy bags and monkey bars. A private Personal Training Zone sits off to one side for sessions with the Platinum-certified coaches. WiFi and charging stations run along the walls. Steam room and sauna sit near the changing rooms, which stock complimentary toiletries and towels.
The class schedule splits between high-output sessions and recovery work. Cycling classes run in a dedicated studio with bike-specific lighting and sound. Group fitness instruction covers the usual HIIT and strength formats. The standout programming is the Aerial Flow Yoga and Hot Yoga, both taught in the Mind and Body Studio. These sessions pull a different crowd than the Boot Camp Zone, which runs interval conditioning with minimal equipment. Personal training here is delivered by Platinum-certified coaches who operate out of the private zone rather than circulating the main floor. The lounge area offers complimentary refreshments, which makes it a practical reset point between sessions when you are deep into a training block and need to rehydrate without leaving the building.
Booking runs through the app only. No walk-ins. The system opens 46 hours in advance, and weekend morning slots fill within the first six hours of that window. Hours are 6 AM to 10 PM Monday through Friday, 8 AM to 9 PM on weekends. Locker rental for shoes is available at the front desk.
