In winter, women should actively carry out cold-resistant exercise and selectively carry out some aerobic endurance exercises, such as walking, jogging, dancing, cycling and playing badminton. This is very helpful for strengthening their physique. Here, I recommend four popular sports methods to female friends. Yoga originated in ancient India and is a kind of physical and mental exercise based on the combination of body, spirit and spirit. Exercise mainly through posture, and then cooperate with conscious breathing to make the spirit return to calm. Yoga can exercise internal organs, glands and nervous system, make muscles, joints, spine and the whole skeletal system more powerful and coordinated, and make the whole body full of vitality. Yoga sculpture is particularly effective for body shaping and weight loss. Tai Ji Chuan has unique effects of self-cultivation, fitness and self-defense. It has special effects on regulating the state of human nervous system and internal organs. Wang Wenyong, director of Chinese Medicine Department of Shanghai Liren Women's Hospital, said: "Tai Ji Chuan pays attention to relaxation and naturalness, which has special effects on relieving mental tension and improving psychological adaptability to the environment. Tai Ji Chuan pays attention to maintaining comfortable abdominal deep breathing, which can promote the peristalsis of internal organs and improve the function of internal organs. " Pilates pays attention to control, stretching and breathing, and the intensity of exercise is not particularly great. It makes the body soft and tough by exercising the core parts of the body. Pilates exercise is very helpful to shape the curve of waist, abdomen and buttocks, and can meet the requirements of modern women for physical beauty. Director Wang Wenyong said: "Shoulder pain, back pain or muscle discomfort caused by sitting for a long time can be improved by Pilates. But also has special effects in treating some diseases, such as constipation and varicose veins. Pilates is suitable for any age group, especially for office workers who lack exercise, need long-term contact with computers and work nine to five. " Zhang, an aerobics fitness coach, told the author that aerobics training can increase vital capacity, promote the oxygen metabolism function of red blood cells in the body, comprehensively improve the physical endurance of trainers and reduce fat content. People who work in the office are prone to different degrees of shoulder and back muscle pain and other symptoms, and it is especially beneficial to do aerobic exercise regularly. The advantage of aerobic exercise is that it can exercise the heart and lungs and make the cardiovascular system deliver oxygen to all parts of the body more effectively and quickly.
