Gyms are generally systematic and professional fitness institutions. All kinds of sports equipment in the venue are relatively complete, and professional fitness coaches provide private training courses for bodybuilders to help fitness enthusiasts avoid some common sports injuries and improve fitness effects. Gym is also the largest category at present, and most amateurs will choose it. Gym can also be said to be a fitness studio, generally built by individuals, with small space and relatively few equipment. Fitness area planning may not be as good as comprehensive gyms, but fitness studios are generally more professional, such as focusing only on physical fitness, or yoga, or reducing fat. Most of the studios are founded by their own fitness coaches. They have many years of experience and professional skills, and they must be proficient in their familiar fields. Therefore, fitness studios are generally suitable for people who just want to provide targeted one-on-one services.
