Is it bad to do fitness while on your period?

I do it sometimes and it never bothers me, So I don’t think so

No absolutely not, it may be uncomfortable for some people, but it shouldn’t stop you from exercising

no..it actually helps me with my cramps

Nope! It helps

Never overdo it or lift really heavy stuff. Otherwise, exercising will only help

No I do it all the time
