肌肉

肌肉 (jī ròu) refers to the soft tissue in the body that allows for movement and physical strength. It is distinct from other body tissues like fat or bone, and is essential for physical activity and overall health.

The character 肌 (jī) originally meant 'muscle' and was derived from the shape of muscle fibers. 肉 (ròu) means 'meat' or 'flesh,' which together emphasizes the physical, tangible nature of muscles in the human body.

In daily life, 肌肉 is commonly used in discussions about fitness, exercise, and health. It is also part of expressions like 肌肉发达 (jī ròu fādá), meaning 'well-developed muscles.' Understanding 肌肉 helps learners grasp terms related to bodybuilding, sports, and anatomy in Chinese.
