Why do you often have weak legs?

Because the muscle that people are most prone to fatigue is skeletal muscle, which accounts for a large proportion, while the lower limb muscles account for almost half of the total weight of skeletal muscle. Lower limb muscles and bones bear the weight of the whole human body, and lower limb muscles are often far away from the brain center and heart. Because of gravity, it is difficult for blood to return to the heart, and poor circulation is most likely to occur in the legs and feet, so the legs and feet are more prone to fatigue than the arms and other tissues, which is what we call leg weakness. Once you exercise or walk for a long time, you feel your legs are weak.

At present, due to the reduction of physical exercise, many people are relatively short of energy substances, and their muscle mass and neuromuscular sensitivity decrease, which is manifested as muscle contraction weakness, that is, leg weakness, especially after standing for a long time or improper exercise.

In this regard, the solution is to increase physical exercise step by step and attach importance to leg muscle exercise, such as dancing, skipping rope and playing ball, which can improve leg muscles, delay muscle decline, improve bones and maintain vigorous gait.

In addition, people who exercise too much are also prone to leg weakness. For excessive exercise, we should first reduce the amount of exercise, pay attention to relaxation and rest, and supplement nutrition before, during and after exercise.
