Postpartum exercise has many benefits, such as helping the body recover, shortening bed rest time, increasing heart rate reserve, improving vasoconstriction and relaxation function, improving postpartum obesity and postpartum depression. Aerobic exercise can improve lung reserve capacity and ventilation capacity, increase heart rate reserve, improve vasoconstriction and relaxation function, and improve postpartum obesity. However, the intensity, mode, time and frequency of aerobic exercise should be within a reasonable range to ensure better results.
