Late in pregnancy to do the appropriate maternity exercises such as arm dumbbell exercises, pelvic eight exercises, phantom chair type exercises can help the production, but also can promote blood circulation, so that the muscles are more flexible, conducive to natural childbirth. 1. arm dumbbell exercise: pregnant mothers can choose 0.5Kg dumbbells or two 500ml bottles of mineral water in the hands, using arm strength to swing up and down, so as to increase the upper limb muscle strength, enhance cardiopulmonary function, relieve shoulder and neck pain. 2. Pelvic figure eight drill: feet open about a shoulder and a half wide distance, the pelvis from the left before the left after the right before the right after the four directions connected, rowing an Arabic numeral 8, which can expand the pelvic ligaments, conducive to the opening of the pelvis, to help the natural childbirth. 3. Phantom chair exercise: feet open and shoulder-width distance, arms raised to the top of the head, inhalation spine upward extension, exhalation flexed hips bending knees hips backward down, back slightly forward about 15 degrees; knees do not buckle or adductor, knees do not exceed the toes. (For the first time practicing mothers-to-be, a square stool can be placed under the hips to ensure safety.) This can prevent and alleviate upper limb edema and enhance the strength of the back and leg muscles. Doing exercises in late pregnancy is recommended to be supervised by a person and under the guidance of a professional to prevent accidents. If you feel uncomfortable during the process of doing pregnancy exercises, you should stop the exercise immediately and seek medical examination immediately.
