First, personal preference.
Although she is a girl, she doesn't like shopping since she was a child. Shopping is always very sleepy. I hate to admit it, but I'm really similar to most boys. When shopping, I feel sleepy and too tired to walk, but it's not like this at all in the gym, so I prefer the gym when I choose the two.
Second, the gym is more atmospheric.
Compared with shopping, the gym has a better atmosphere to lose weight. People around you are working hard and sweating, which will easily be driven up. For example, if you ride a spinning bike and move with carefree music, if you are tired of shopping, find a place to sit down, or you may want to eat another ice cream. In the end, the calories consumed by shopping are in contrast to the calories consumed, which is equivalent to not shopping. The point is that shopping costs money. Shopping is not a good idea for low-income people. Not only lost weight, but also spent a lot of money in the end. It's a little too much to think about.
Third, the gym is more comprehensive and professional.
Shopping can only consume calories in the body, and at most it can exercise or lose weight, but it can't play a role in fitness. You know, the gym has a lot of equipment and is guided by a fitness instructor, so it will be more professional. Moreover, the equipment inside is suitable for all kinds of people. For example, girls can choose yoga, and if they like swimming, they can also choose swimming. Shopping is impossible. If you just want to keep fit or lose weight, then shopping is really a good choice, but for many people who want to exercise professionally, shopping has little effect.
