Exercise as little as possible during menstruation, but you can take a walk. If you exercise too much during menstruation, it will easily lead to excessive bleeding and abdominal pain. What I am most afraid of is that strenuous exercise will crush me, so as to avoid the sequelae of frequent bleeding in the future. But the most effective way to lose weight after menstruation is 2-3 times as much as usual. Almost all the female students in my class use the days after menstruation to lose weight. The effect is particularly good.
