Proper exercise should make all parts of the body muscles, joints, limbs, internal organs (heart, lungs, brain, etc.) get exercise. ) you can exercise. When exercising, we should take into account the symmetrical movements of the left and right hands and feet, chest and abdomen and back, ears, eyes and upper and lower teeth. For example, stretching and bending, rotating and turning, pressing Monet, pinching and pushing, walking and running, swimming and cycling can be done alternately. It is best to alternate internal work and external work, and combine static and dynamic work.

Acid swelling is actually caused by lactic acid. Lactic acid is an intermediate product of muscle metabolism during exercise. When lactic acid accumulates in muscles, the body will feel sore. Many people often give up exercise because of this feeling, which is actually wrong. At this time, a little more exercise can be just right.

If you have loss of appetite, dizziness, headache, fatigue, sweating and listlessness after exercise, it means that the amount of exercise is too large, which exceeds the tolerance limit of the body and will damage the body due to overwork. Sun Simiao warned people in "A Thousand Daughters to Be Prescribed": "The way to cultivate one's morality and cultivate one's nature is always hard work, but it is impossible to be exhausted and strong." So, how to master the amount of exercise is appropriate? Generally speaking, it is advisable not to feel excessive fatigue after each exercise; Some people also use pulse and heart rate as indicators of exercise. If you do a lot of exercise, your heart rate and pulse rate will be faster. For normal adults, it is appropriate to increase the heart rate to 140 beats per minute; For the elderly, the exercise should be increased to 120 times per minute.
