TOM just started this morning. I was a bit hesitant to do my 60min. planned jog today, particularly because of TOM and because I did a 60min. jog yesterday, so I thought I'd be sore as normal. In short, I was having a rough time getting out the door.
I'm glad I went. I don't know if anyone else has noticed this:
My joints felt extra fresh, my breathing was extra calm, the first 30 minutes was an absolute breeze. It was an amazing run. This is a BIG guess, but, you know how they say the cramping you experience during your period mimic those you experience during the birthing process? That cramps, in a way, prepare one for childbirth? The cramps are accompanied by endorphins produced by the body this time of the month AND then you have the endorphins that come from the exercise itself.
All the endorphins made me feel like I was floating today instead of running. So, my advice is to ALWAYS exercise during your period - particularly in the first few hours it begins.
One more thing: normally my period starts off spotty and I have to wait a good 7-8 hours for it to really get going and then I have bad bad cramps. After the 60 minutes, my period was in full swing and the cramps have been super minimal. I really shook everything lose - maybe similar to pregnant women who engage in brisk walking to speed up their due date.
