My wife is obsessed with going to the gym. What should I do? What is the most effective way to stop it?

The gym has a strong fitness atmosphere. Your wife may have taken a fitness class, or she may have friends to go with her. Why didn't you let her go after spending money? Fitness is a good thing, and some people don't have this condition yet. You can try to distract her, for example, before she goes to the gym, take her to places of interest such as entertainment, or spend some money to please her and buy him a gift, and she may listen to you. Are you fighting? If it really doesn't work, take her to see a doctor.
