Niyama Private Fitness in Chiang Mai is a fitness center or gym that offers a variety of services aimed at individuals who are looking to maintain their physical health, improve their fitness level, or achieve specific fitness goals. However, as I don't have real-time access to the internet or the most up-to-date databases, I cannot provide current details or specifics about the facility, such as its exact address, membership fees, or the range of equipment and classes offered.

Typically, facilities like Niyama Private Fitness would offer personal training, a variety of fitness classes, and possibly amenities such as yoga, Pilates, weight training, cardiovascular machines, and more. They might also offer specialized programs, nutrition advice, and wellness services.
