Vithawat Muay Thai was founded in 2011 by a professional fighter providing professional training and exercise training. This small, homestyle gym has a matted training area and a few bags but no ring. It's more than enough for your private, one-on-one training lesson. They have very nice shower facilities in the house on the property.
The gym may be small, its name relatively unknown, but they pack a punch with a talented roster of trainers. All ex-professional fighters, Rungrit T.Anusorn (Berm) was a multiple Lumpinee champion who previously taught at Tiger Muay Thai. Sirimonkol PK (Stereo) is another former champion (both Lumpinee and Rajadamnern).
The price alone makes it a very attractive training option but they are also very welcoming to foreigners. The best thing about this gym is they start lessons from 7am. While almost every other gym and trainer in the city is sleeping, at Vithawat you can sneak an early-morning session in before work or a day's sightseeing.
