Moderate exercise during menstruation is not only possible but recommended, according to WebMD. The website explains that exercise releases beta-endorphins, which act as a natural analgesic and ease pain from menstrual cramps and other unpleasant symptoms.
Aerobic exercise releases the most endorphins, which makes it the ideal way to exercise during menstruation, according to WebMD. The best exercises include brisk walking, biking, swimming and skating, all of which increase the heart rate as well as the production of beta-endorphins. Health.com notes that some yoga poses, such as the cat and cobra, not only provide a great workout but alleviate cramps and the emotional symptoms of menstruation as well.
