I found this article on the pelvic floor http://www.bbc.com/future/story/20180717-the-pelvic-floor-is-still-a-mystery-in-anatomy and wanted to share it. I thought it was very interesting and it also made me think about how important it is to use and exercise those muscles. Remember to engage mula bandha and uddiyana bandha!
Having never looked this up, I was surprised to see the spelling of "bandha." Useful information.
