A variation of a cat cow that brings focus to your pelvic area, this exercise isn’t physically challenging but should help you to tune into the movements in your pelvic floor.

Start on your hands and knees, letting your spine hang downward and keeping your head raised, before pulling your belly button up towards the ceiling and rounding your back like a cat. Let your head hang free.
Begin flowing between the two positions. What is your pelvis doing? How are your pelvic bones moving? Try to feel them in your body. Ideally, you would notice that, in the cow position, your sit bones pull apart while your tailbone and sacrum pull backward from the body and away from your pubic bone. This makes your pelvis wider at the bottom, stretching your pelvic floor wide open. Maybe you can feel a real pull in your first pelvic floor layer? Try to relax there to give it a nice, natural stretch. In the cat pose, the sit bones come together, and the tailbone and sacrum approach the pubic bone again. This makes your pelvis narrower as the pelvic floor contracts.
Now you can consciously draw your sit bones together in cat pose and notice the activation of your pelvic floor. Deliberately pull them apart in cow pose and notice the stretch in your pelvic floor.

Is your low libido being caused by a weak pelvic floor?
