MYTH MONDAY
MYTH: The pelvic floor is its own separate system, so if something's off, you only need to work on the pelvic floor.
TRUTH: Your pelvic floor is part of a team. It works with your diaphragm, deep abdominals, low back muscles, glutes, and hips, and it's constantly adjusting to your breath and movement.
Think of your core as a canister:
đż The diaphragm is the lid
đż The abdominals wrap the front and sides
đż The back muscles (multifidus) support the spine behind
đż The pelvic floor is the base
These parts are designed to move together, and breathing is what keeps them coordinated:
INHALE: Your diaphragm drops down, your ribs expand, and pressure in the canister increases. Your pelvic floor responds by gently lengthening and relaxing downward.
EXHALE: Your diaphragm rises, pressure decreases, and your pelvic floor and deep abs naturally engage and lift.
It also happens without you thinking about it. When you cough, laugh, lift a grocery bag, or stand up from a chair, a healthy pelvic floor and deep core activate just before you move, to manage the pressure. Your glutes and inner thigh muscles connect into the pelvic floor too, so tension or weakness in your hips can change how it functions.
When one part isn't doing its job, another takes over. Holding your breath, clenching your glutes, or gripping your abs can leave the pelvic floor overworking or unable to respond when you need it. That can look like leaking, heaviness, pain with intimacy, constipation, or low back and hip pain.
This is why pelvic floor PT looks at how you breathe, move, and manage pressure, not just the muscles you can't see.
