This may be because it will be embarrassing, but I don't think so. It's really convenient to have a gym in the office. You can go directly to the gym after work every day, which naturally saves a lot of time. Many people don't want this opportunity yet, but you don't cherish it. This is very strange.
I have a friend whose company has a gym. He goes there almost every day. Because he is his own employee, it will be much cheaper to apply for a card, which is equivalent to half the price outside. This price is really affordable for the gym. I think we should cherish this opportunity instead of treating the gym as more than one place. This will waste the company's hard work and a once-in-a-lifetime plastic exercise opportunity.
To sum up, most of the company's gyms are built to make the whole company look better, and a few are also for the convenience of employees, so that everyone has enough time and space to exercise. Why not? Everyone must hurry up and make good use of this gym for fitness.
