1. Never exercise during menstruation.
First of all, I still stick to my point of view. You must never go to the gym during your menstrual period. Be sure to wait until the menstrual period is over, so that you can take part in some intense exercise. Because fitness requires physical exertion. You need to use every muscle of your body. Because girls are very fragile during menstruation and weak. So it is not suitable for these sports at all.
2. If you insist on fitness, you will leave sequelae for yourself.
Secondly, if you insist on fitness, it will do some harm to your body. And it will leave sequelae for the body in the future. Every time I have my period, I feel extremely painful. I'm sure you don't want to see this happen either. So I hope you don't go to the gym during your period.
In short, you can't go to the gym during your period. For most women, menstrual period is very fragile. At this time, you must cherish your body and pay attention to rest. If you want to go to the gym at this time, I believe neither your friends nor your relatives want to.
