Second, introduction:
1. Animation, that is, animation and comics. Combining the first words of these two words is called "animation", which is not a technical term. Animation is a collection of animation and comics, and the relationship between animation and animation is the relationship between inclusion and inclusion, not the same relationship.
All animation and comic works can be called animation works, but it can't be said that animation or comic works are animation, because semantically speaking, animation and comic works are two different art forms, and there is no such art form as "animation", which is just a compound word created by China. On many occasions, the word "animation" is misused to refer to "animation", which is very easy to cause ambiguity.
2. Abdominal muscles: Abdominal muscles are an important part of human connective tissue, including rectus abdominis, external oblique abdominis, internal oblique abdominis and transverse abdominis. When they contract, they can bend and rotate the trunk to prevent the pelvis from leaning forward. Abdominal muscles also play an important role in the activity and stability of lumbar spine, and can also control the activity of pelvis and spine. Abdominal muscle weakness may lead to pelvic forward tilt and increase the physiological curvature of lumbar spine, increasing the chance of low back pain.
3, the method of exercising abdominal muscles: make an exercise plan and change the diet.
