The training of leg muscles is the most easily overlooked. People pay little attention to it because there are not many training moves specifically for it, and the results are slow, and the leg muscles are not exposed as often as the arm muscles or abdominal muscles.

First, the thigh muscle group is the largest muscle group in the human body. A person's aging is accompanied by muscle loss in physiological structure. As the largest muscle group, thigh is also the first choice for muscle loss. This kind of aging will show some signs at the age of 30, but it will increase rapidly after 60. Therefore, we often see that as people get older, their movements become less and less, and their steps become less and less vigorous.

Second, the leg is the main transportation hub and blood circulation organization of the body, occupying 50% of the nerves and blood vessels of the human body, flowing 50% of the blood and bearing the main weight of the body for a long time. However, due to some bad living habits and body shapes, there are more or less different degrees of wear and deformation over the past few decades, which will increase the burden on lower limbs and the speed of aging.

Third, due to improper or excessive consumption of joints and tendons in youth, people often have problems such as rheumatism, arthritis, hyperosteogeny and muscular atrophy after middle age, which greatly affects the quality of life and makes people feel aging directly.
