Singpatong Sitnumnoi, now known as Petchnumnoi, is a premier Muay Thai training camp located at 15 Phisitkharanee Road, Patong Beach, Kathu District, Phuket. Established in 1971 by Somsak Junlaka, a professional Muay Thai fighter, the camp has been a cornerstone of traditional and authentic Muay Thai training. In January 2025, Singpatong Sitnumnoi underwent a significant rebranding to become Petchnumnoi, reflecting its evolving identity and commitment to excellence in Muay Thai training. The camp boasts two fighting rings and a spacious training area on 4 Rai of land, and offers a wide selection of high-quality training equipment and gear for purchase, including Muay Thai shorts and gloves in various designs and colors.

Under the operational leadership of head trainer Somnuek Phatburee, known as Sit NumNoi, Petchnumnoi is staffed by renowned trainers such as Runganan Sitnumnoi (Anan), Komsan Saktewan (Komsan), and Kongpayak Sorjorsuwit (Mad). These trainers are celebrated throughout Thailand for their expertise and dedication to training the next generation of fighters through a rigorous program that admits 2-3 Thai nationals annually. This program includes two training sessions daily, from Monday to Saturday, focusing on building fighters’ skills and physical endurance to prepare them not only for national but also international competitions.

The training at Petchnumnoi encompasses a 10-kilometer run through mountainous terrain, clinching, sparring, eight rounds in the ring with a designated trainer, shadow boxing, skipping, sit-ups, push-ups, and stretching, all designed to build stamina and physical strength.

Initially reserved for local fighters, Petchnumnoi has opened its doors to foreign fighters due to the increasing global popularity of Muay Thai. These international trainees can participate in short programs ranging from a day to six months, although they typically do not compete under the camp’s name post-training. Both local and foreign fighters leave Petchnumnoi with a solid foundation in the skills and techniques essential for success in Muay Thai, reflecting the camp’s commitment to high standards and comprehensive training.
