Doing the following five kinds of exercise before pregnancy is helpful for pregnancy: First, walking is an exercise suitable for anyone. Take a walk in an environment with fresh air as much as possible. Don't walk too fast or too long. At the beginning, you can slow down and don't walk too fast, lest your body shake too much and cause fatigue. Don't wear high shoes when walking, but wear sports shoes with soft soles. It is best to take a walk for a period of time every day, and don't go out for a walk on foggy, rainy and snowy days to avoid accidents. Second, jogging or brisk walking, the right weight is helpful for pregnancy. Jogging or brisk walking can consume more energy and burn excess fat than walking. Empty your bladder before exercise and put on loose and comfortable clothes. If you feel uncomfortable during the period, you can pause to rest and adjust the jogging time according to your physical condition, so it is not easy to get tired. Just like walking, please do it in an environment with fresh air and spacious space. Swimming, swimming is a very good exercise method, which can increase the strength of supporting weight and improve endurance and flexibility. Swimming can increase heart and lung function, improve mood and help maintain a good attitude during pregnancy. It should be noted that the swimming time should not be too long and the water should not be too cold, otherwise it will cause muscle spasm. Yoga, practicing yoga can enhance physical strength and muscle tension, enhance the sense of balance of the body, and improve the flexibility and flexibility of the whole muscle tissue. At the same time, yoga can also stimulate glands that control hormone secretion, accelerate blood circulation, and help pregnant women master breathing control methods well, which is conducive to future delivery.
