Is it OK to do cardiorespiratory endurance exercise while menstruating?
AYes. There is no evidence that exercise during menstruation is unhealthy or that it has negative effects on performance. If you have headaches,
backaches, and abdominal pain during menstruation, you may not feel like exercising. For some women, exercise helps relieve these symptoms. Listen to your body and exercise at whatever intensity is comfortable for you.
