Pelvic Floor and Low Back Pain: The Hidden Link & How to Find Lasting Relief
4 Min Read
If you’ve been struggling with stubborn lower back pain, you might be missing a crucial piece of the puzzle. While most treatments focus exclusively on core musculature, there’s a hidden connection that could be the key to your relief: your pelvic floor. I’m going to share why these two areas are inseparable and, more importantly, what you can do about it.

Understanding the Connection Between Pelvic Floor and Low Back Pain
Picture your body like a favorite shirt. If you tug on the hem, you’ll feel that pull elsewhere in the fabric, right? Your body works the same way — tension in one area can show up in other areas of the body.
Your core isn’t just your “abs”— it’s an integrated system I like to call the “core canister,” which includes:
- Your pelvic floor – a collection of muscles at the bottom of your pelvis
- Your diaphragm– the dome-shaped breathing muscle at the top
- Your transverse abdominis– the deep abdominal muscle that acts like a corset wrapping around your abdomen
- Your multifidus (small muscles running the length of your spinal
- Your glutes– yes, your glutes play a key role in core and pelvic floor function
These structures work together constantly, whether you’re aware of it or not. When your pelvic floor isn’t functioning properly—whether too tight (this doesn’t mean strong!) or too weak (and this doesn’t mean loose!)—it directly impacts how your lower back feels and functions.
Common Low Back Pain Causes Related to the Pelvic Floor
Lower back pain from a tight pelvic floor
A tight, hypertonic pelvic floor is surprisingly common and often missed in traditional assessments. This chronic tension restricts the natural movement of your pelvis, forcing your lower back to compensate. Many people don’t realize they’re constantly “gripping” these muscles until they learn to release them, relieving lower back pain from tight pelvic floor muscles.
Weak pelvic floor and lower back pain
On the flip side, a weak pelvic floor doesn’t provide adequate support for your spine or organs. This often develops after pregnancy, with aging, or from prolonged sitting. When your pelvic floor can’t do its supporting job, your back muscles try to pick up the slack—and they weren’t designed for this role.
How posture affects pelvic floor and back pain
I often see two problematic postural patterns in my practice:
1. Tucking your pelvis under (posterior tilt): This flattens your natural lumbar curve, shortens the muscles of the pelvic floor, and compresses your abdomen. It’s common in those who’ve been told to “tuck your tailbone” or “protect your back” during exercise.
2. Overarching your lower back (anterior tilt): This creates excessive compression in your lumbar spine and strains your back and pelvic floor.
Both patterns disrupt the optimal balance of your core system and can contribute to persistent pain.
Symptoms of Low Back Pain and Pelvic Floor Dysfunction
If you’re experiencing low back pain, check if you have any of these pelvic floor symptoms as well:
- Hip pain or limited hip mobility
- Painful intercourse or difficulty achieving orgasm
- Pain following orgasm
- Urinary incontinence, frequency, or urgency
- A sensation of constant tension or “gripping” in the pelvic region
- Hemorrhoids
- Tailbone pain
- Constipation
- Feeling like you can’t fully empty your bladder
- A sense of heaviness or pressure in your lower abdomen
With over 25% of women experiencing pelvic floor dysfunction at some point in their lives [2], these symptoms are far more common than most people realize.
For women, hormonal fluctuations throughout the month affect ligament laxity and muscle tone in the pelvic region. During pregnancy, hormones like relaxin increase joint mobility, and these effects can linger postpartum. Later in life, menopause brings another set of hormonal shifts that impact these same structures.
How to Relieve Lower Back Pain by Addressing the Pelvic Floor
Why traditional lower back pain treatments don’t always work
If you’ve tried stretching your back, strengthening your core, massage, or even medication without lasting relief, the missing piece might be the pelvic floor connection. Traditional approaches often treat your back or core in isolation, ignoring how interconnected your body really is.
The importance of breath for optimal pelvic floor function
Your breath orchestrates the relationship between your diaphragm and pelvic floor. When you inhale, your diaphragm descends, and your pelvic floor should gently lengthen. On exhale, your diaphragm rises, and your pelvic floor should gently lift. This coordinated “dance,” for one reason or another, can be out of sync, leading to pain, limited mobility and other symptoms.
Try this: Place one hand on your lower belly and one on your side ribs. Breathe in, allowing your ribs to expand in all directions. As you exhale, pretend you’re blowing out 100 candles on a birthday cake. Do you feel a gentle lifting sensation in your pelvic floor? Or do you feel an increase in pressure on the pelvic floor? If it’s the latter, that means your diaphragm and pelvic floor are not working together optimally.
4 Key Exercises to Relieve Lower Back Pain and Improve Pelvic Floor Function
These four exercises address both your pelvic floor and lower back simultaneously. Practice them consistently for the best results.
1. Cat-Cow with Pelvic Control — Mobilizing the spine properly
This yoga staple becomes much more effective when done with awareness and incorporating candles breath:
- Start on hands and knees
- Important distinction: Begin the movement from your pelvis, not your spine
- For “Cat” pose: On a candles exhale, begin to tuck your pelvis under, then let that rounding flow up your spine
- For “Cow” pose: On an inhale, initiate by untucking your pelvis before allowing the arch to travel up your back
- Move slowly through 8 repetitions, focusing on the connection between your breath, pelvis, and spine
This pelvic-first approach and incorporating the breath make a world of difference in releasing tension patterns that connect these areas.
2. Standing Windmill Stretch — Core stability and pelvic and hip mobility
This dynamic movement demands stability from the core while lengthening the pelvic floor:
- Stand with feet wider than hip-width (right foot faces forward, left foot slightly angled out)
- Bend your right knee slightly and reach your left arm up
- As you exhale, hinge at your hips (not your waist) to reach your left hand down toward your left foot
- Maintain length in your spine rather than rounding
- Feel the lengthening of the left inner thigh (and pelvic floor)
- Hold for 5 breaths before switching sides
This exercise teaches your body to move from your hips rather than overusing your lower back—a key distinction for pain relief.
3. Inner Thigh Activation — Supporting pelvic alignment
Your inner thighs (adductors) play a crucial role in pelvic floor function that’s often overlooked:
- Kneel on a cushioned surface with knees hip-width apart
- Extend one leg to the side, keeping your foot on the floor
- On a candles exhale, keep your spine long, hinge slightly forward at your hips
- Hold briefly, before coming to back to your starting position
- Repeat 8-10 times on each side
Strong, flexible adductors help maintain proper pelvic alignment, reducing strain on both your pelvic floor and lower back.
4. Internal Rotation Exercise — Unlocking hip and pelvic mobility
Most exercise routines neglect internal hip rotation, yet it’s essential for pelvic function:
- Lie on your side
- Place a yoga block or firm pillow in front of you
- Rest your top leg on the block and gently rotate your knee inward; your foot will lift
- Keep your spine long rather than collapsing
- Perform 8-10 gentle rotations per side
This movement helps restore balance to your hip muscles, which directly influences how your pelvis and lower back.
Taking Control of Your Pelvic Floor and Low Back Pain
The connection between your pelvic floor and low back pain isn’t just theory—it’s the missing link I’ve seen transform outcomes for countless clients who thought they’d tried everything. Research strongly supports this relationship, with a 2018 study revealing that an overwhelming majority—nearly 95%—of individuals experiencing lower back and pelvic pain also showed signs of pelvic floor dysfunction [1].
Remember that healing is rarely linear. Some days will feel better than others as your body adapts to new patterns. Be patient with yourself, and consider working with a pelvic health physical therapist if your symptoms are severe or persistent.
For those wanting a structured approach to healing, I’ve developed the RYC® 12-Week Program to support both core and pelvic floor recovery while also addressing back pain. The program guides you step by step through progressive, targeted exercises designed to help you reconnect with your body and build lasting strength.
By working with these interconnected areas together, you give yourself the best chance at meaningful, long-term relief. Your body doesn’t function in isolation—and your approach to healing shouldn’t either.
FAQ
1. How do I know if my lower back pain is related to pelvic floor dysfunction?
Look for accompanying symptoms like urinary urgency or leakage, constipation, pain during sex, or a feeling of heaviness in your pelvis. Also, consider whether your back pain began after pregnancy or a significant life change. These connections often point to pelvic floor involvement.
2. What are the signs of a weak pelvic floor and low back pain?
Signs include leaking urine when you cough, sneeze, or jump, a feeling of heaviness in your pelvis, diminished sensation during sex, and difficulty fully emptying your bladder. With back pain, you might notice increased discomfort after prolonged standing, sitting or activities requiring stability.
3. What causes lower back pain in females, and how is it linked to the pelvic floor?
Lower back pain in females frequently results from pelvic floor dysfunction since these areas form one integrated system. The pelvic floor muscles support the spine and pelvic organs, and when they become either too tight or too weak, they alter pelvic mechanics, forcing the lower back to compensate. This connection is especially significant in women due to anatomical differences in the pelvis and the effects of pregnancy, childbirth, hormonal cycles, and menopause on these interconnected structures.
4. Can tight pelvic floor muscles cause lower back pain?
Absolutely. A chronically tight (hypertonic) pelvic floor restricts the natural mobility of your pelvis, forcing your lower back to compensate. This creates a pattern of tension that can manifest as persistent aching, stiffness after sitting and standing, or sharp pain with certain movements.
5. What is the best way to relieve lower back pain naturally?
The best way to relieve lower back pain naturally is to combine proper breathing, mindful movement, and an understanding of the mind-body connection in pain. Instead of thinking about the back in isolation, focus on the entire core system—especially the link between the pelvic floor and the lower back. The RYC® Program is built on this principle, gradually improving strength and awareness. Research supports this approach, showing that pelvic floor muscle strength and mobility increase with consistent, appropriate exercise over time, regardless of intensity [3]. Gentle, consistent practice often outperforms aggressive stretching or strengthening.
6. How long does it take to see improvement in low back pain when addressing the pelvic floor?
While everyone’s healing journey is different, many people begin to notice subtle improvements within 2-3 weeks of consistent practice. More significant relief often comes within 6-8 weeks as the body establishes new movement patterns and the nervous system adapts. Remember that healing is rarely linear—some days will feel better than others as your body learns and integrates these changes.
