You can't say that people who wear heavy makeup don't exercise seriously. After all, the gym is also a public place. Some people want to make up, others think it is a habit and an attitude. We have no right to ask, nor can we simply think that they have not exercised seriously. They want to show their beautiful and glorious side in front of people. This is normal and understandable.
Maybe you think they spend their makeup after sweating, so you think they don't exercise seriously because they don't want to lose their makeup, but there are still many cosmetics that are waterproof and sweat-proof. People who can afford to go to the gym don't necessarily buy cheap cosmetics. Many cosmetics are durable and well colored.
Of course, it is not good to wear heavy makeup for fitness. When we exercise, the metabolism of blood will be accelerated, pores will be opened, and oil and sweat will be metabolized. However, if we wear heavy makeup, it will clog pores, resulting in large pores and bad skin, so it is better to wear plain makeup or light makeup to keep fit. Although it is not recommended to wear heavy makeup to the gym, we can't tell whether people who wear heavy makeup are exercising seriously, but people who love fitness will definitely know the disadvantages of wearing heavy makeup.
