The pelvic floor is a group of muscles that support your pelvic organs. These muscles work like a sling that span from your pubic bone in the front, and attach to the back at your tailbone. These muscles are similar to like any other muscle in which we can strengthen, stretch, and train them.
What makes them special (and more complex) is that unlike normal muscles, they are highly affected by hormones and stress, we sit on them all day, AND they are working ALL the time to prevent urinary or fecal accidents.
The function of these muscles is to control bowel and bladder function, role in childbirth and intercourse, but also stabilize our hip complex. These muscles are hip muscles and have a close connection to the core and gluteal muscles as well.
