Personal privacy Abdominal muscles, like other muscles, need persistent exercise and time to gradually develop and strengthen. Even if you do a lot of exercise, it is difficult for your abdominal muscles to change significantly in a short time. Therefore, asking about other people's abdominal muscles may make bodybuilders feel stressed and depressed. Fitness is a lifestyle chosen by individuals, and everyone pays different attention to fitness and openness. Some people may be reluctant to share their fitness progress or physical changes, especially when such information is regarded as private domain. Therefore, asking about other people's abdominal muscles may be regarded as an invasion of others' privacy.
