Boost Fitness Bangkok
36 Ramkhamhaeng Rd, Khwaeng Saphan Sung, Saphan Sung, Bangkok 10240
The founder's competition pedigree shows in the equipment choices and the trainer roster. If you want a neighborhood gym with the depth of a central-Bangkok fitness club but without the central-Bangkok pricing, this is the anchor. The Diamond membership at ฿4,000 per month unlocks the full class schedule. Lead with the strength zone, then try a BodyPump session to see why the Home of Champions tagline holds.
You walk in off Ramkhamhaeng Road into the strength zone. The equipment is organized by muscle group, the trainer station sits center floor, and electric lockers line the entrance. This is a serious training room built by someone who understands how competition gyms operate.
Tee Tee Pornpaisarn Reungsaengphet, Thailand's first IFBB PRO Olympian and an IFBB Men's Physique competitor, founded Boost Fitness with a specific training philosophy: world-class equipment, certified trainers, and a class schedule that serves both strength athletes and group-fitness clients without shortchanging either. The Standard membership at ฿3,300 per month covers the strength zone, cardio zone, steam room, lockers, and towels. Diamond tier at ฿4,000 opens the full LesMills class schedule (BodyPump, BodyCombat, RPM, BodyBalance, Dance) plus app-based booking, which helps when evening slots fill. Four certified trainers work the floor: Tangkwa, Em, India, and Benz. The Pilates Reformer studio runs separately at ฿700 per session, and the reformer program here leans athletic rather than spa.
LesMills classes run 45 to 55 minutes with calorie burns between 200 and 500 depending on format. HIIT, yoga, Zumba, and functional training sessions rotate through the weekly schedule. The steam room sits next to the locker area and sees heavy use after evening training. A swimming pool is listed among amenities, so confirm access details and hours when you sign up.
The location sits east of central Bangkok. If you are based in Sukhumvit or Silom, this will not be your corner gym. But the founder's competition pedigree shows in the equipment choices and trainer expertise, both rare in outer-district gyms, and the ฿3,300 entry sits well below what similar depth costs near the BTS core. Book Diamond for full class access.
