I think that two people can become boyfriend and girlfriend, first of all, it should be a process from acquaintance to understanding. Since you like the fitness instructor in the gym, I think you can get a fitness card first, and then hire him as a personal trainer to teach you fitness. In this way, you two can understand. In addition, you can always contact him on WeChat or phone every day and often send him some questions.

When you get familiar with it, you can find a way to ask him to help you solve some personal problems. Apart from this fitness problem, you can ask him to help you, such as helping you move things, and then you have reason to thank him, and then you can invite him to dinner or give him a gift.

In addition, you can also try to find people you know together. You can invite them to go out to play, eat and sing together, or climb mountains together and wait for you here. When you are away from home, you will have more and more contact during working hours. You will get to know each other more and more. When you two have personal communication with each other, you can get to know each other better. You can like to know what some of his preferences are, and then you can do whatever you want. Otherwise, you can thank him for his help, or you can help him occasionally, so that after you have more people, you will gradually develop your feelings.

In fact, whether men chase women or women chase men, they should take this step bravely and let him feel that you like him. If he says he likes you, he will respond to you slowly. Even if he refuses to chase her later, you won't regret it, but if you don't take this step to chase her, you will probably regret it very much later. It is possible to miss a better fate.
