Gyms generally adopt the annual membership system and the business model of sales staff to induce members to consume value-added services again. There are many kinds of training in the gym, and the training items and courses are also comprehensive, such as aerobic training, muscle bodybuilding training, stretching courses, yoga courses, group gymnastics and so on. These projects can be carried out in the gym. Usually, the items with the largest number of people trained in a gym are physical training, reducing fat and shaping, and strengthening muscles. People can accomplish their training goals through various instruments. A large number of treadmills can meet people's basic physical training requirements, and can also achieve the purpose of shaping and training muscles by using various mechanical equipment. If there are problems in the training process, you can ask the fitness instructor present, and the general coach will give some help to induce members to buy value-added items again. To sum up, the gym is more suitable for people with simple needs or training experience. They don't need to spend value-added items, they just need to buy annual cards, usually around 2000-3000. For fitness white, without experience and foundation, the gym is obviously not suitable. Maybe the private education studio is a better choice.
