Senza™ 4-in-1 Pelvic Floor Activator
4-in-1The pelvic floor device you'll actually look forward to using — because the pleasure is what makes it work.

✓
No squeezing. No guessing. Therapeutic vibration triggers your pelvic floor automatically — you just feel it working
✓
Feels genuinely incredible — because pleasure is the only thing that makes you consistent, and consistency is what actually rebuilds your pelvic floor
✓
Bladder confidence in weeks — 96% of users reported less leakage during running, sneezing and laughing within 8 weeks
✓
4 independent zones, fully hands-free — reaches the deep muscles manual Kegels almost never activate
✓
No app. No Bluetooth. No $200 device in a drawer. Just 5 minutes a day you'll actually want to do

Frequently Asked Questions
How does the 4-zone stimulation work?
Four independent motors target four distinct zones simultaneously:
- Clitoris — pressure wave suction
- G-spot — internal vibration
- Vaginal wall — deep low-frequency activation
- Perineum — gentle optional vibration
Why this matters for pelvic floor training: multi-zone activation creates neurofeedback loops that reinforce conscious control and muscle engagement. Your brain learns to map and control these internal muscles more effectively than with manual Kegels alone.
Each zone can be controlled independently — use all four or personalise the intensity per zone. The combined stimulation produces an orgasmic effect while providing biomechanical resistance for pelvic floor strengthening.
Is it body-safe and hypoallergenic?
Yes. 100% medical-grade silicone — entirely body-safe, non-porous and hypoallergenic.

A Letter From Our Founder
I built Senza because I quit my own pelvic floor program in three weeks.
After my second daughter was born, I had every advantage. The right device. A postpartum physical therapist who told me exactly what to do. An app on my phone that buzzed at 8 a.m. every morning. And by week three, the device was in a drawer next to every other expensive purchase I'd given up on. I felt like a failure. I was a 36-year-old woman with two healthy kids and access to the best care money could buy, and I couldn't get myself to do a ten-minute routine.
What I learned over the next two years — talking to physiotherapists, gynecologists, and hundreds of women in their forties and fifties — was that I wasn't the problem. The protocols work. The devices work. The science of pelvic floor strengthening has been settled for decades. What nobody talks about is the only variable that actually decides outcomes: whether you'll finish what you started. Traditional Kegel programs have a 10–15% adherence rate. The dirty secret of the entire category is that almost no one finishes them.
Compliance isn't a personality flaw. It's an engineering problem. And I refused to release another product that asked women to fix themselves before they could feel better.
Senza is built around that variable, and that variable alone. Every design decision — the silence under 40 decibels, the four targeted modes, the integration of pleasure into training itself — exists for one reason: so the woman who buys this actually opens the box on day six. Day twenty. Day sixty. If you've been disappointed before, I understand exactly what that feels like. This is the product I needed and couldn't find. I built it for both of us.

#1 AT-HOME PELVIC FLOOR DEVICE
The Leading At-Home Pelvic Floor Strengthening Ritual

Deep Pelvic Activation
Helps activate the deep muscles manual Kegels often miss.
Effortless Results
No squeezing, no guessing. Senza supports activation for you.
Bladder Confidence
Designed to support confidence during laughing, coughing, and movement.
Confidence & Freedom
Feel more in control, more secure, and freer in everyday life.
How your body responds step by step
An overview of what many women experience in the first weeks, as your body adapts to targeted, hands-free stimulation designed specifically to support your pelvic floor.
How your body responds step by step
Week 1–2
THE GUILT LIFTS
The first time you use Senza, something is different. It stays in place. The sensation is deeper than anything you've felt from a device before — not surface-level, not mechanical. And for the first time, you realise something: the shame you've been carrying about needing help, about quitting, about "not being disciplined enough" — it starts to dissolve. Because your body was never the problem. It was always the method.
Week 3–4
SOMETHING SHIFTS
You notice you've used it every day this week. Not because you set a reminder. Not because you forced yourself. Because you actually wanted to. Your pelvic floor is responding — you can feel it engaging in ways it never did with manual Kegels. The connection to your core that faded after pregnancy, after menopause, after years of being told to "just squeeze" — it's coming back.
Week 5–8
YOU SNEEZE. NOTHING HAPPENS.
This is the moment. You're at the gym, or laughing at dinner, or running after your kids — and you realise you didn't think about it beforehand. You didn't cross your legs. You didn't brace yourself. You just lived the moment. Many women say they nearly cried the first time this happened. We understand why.
Week 9+
YOU STOP THINKING ABOUT IT.
That constant background calculation — where's the nearest bathroom, do I have a pad, can I laugh at this joke — it's gone. You've replaced $600 worth of devices that didn't work with one that did. Not because you were more disciplined this time. Because this time, the device was finally built around you.
Why this time is different
Every device you've tried asked you to do the work. Senza is the first one built around the only reason women actually stay consistent.

Frequently Asked Questions
How is Senza different from other pelvic floor solutions I’ve tried?
+
Senza combines targeted stimulation and controlled movement in one device. Where alternatives often rely on passive vibration or function only as a “trainer,” Senza activates multiple zones simultaneously and provides real resistance that your pelvic floor muscles respond to. This makes training more effective and more enjoyable to stick with.
Will Senza fit my body?
+
Yes — Senza is designed to adapt to different body shapes and anatomies. Thanks to the flexible medical silicone and ergonomic shape, it sits comfortably without feeling uncomfortable. If it doesn’t feel like the right fit, you can return it within 60 days free of charge.
What if it doesn’t work for me?
+
You can try Senza risk-free for 60 days. If you don’t notice consistent improvement, you can easily return the product and receive a full refund. No unnecessary conditions, no hidden fees.
Is the suction/pressure really different from regular vibration?
+
Yes. Instead of only surface-level vibration, Senza uses pressure (suction) combined with targeted stimulation. This ensures deeper activation of the pelvic floor muscles and stimulates the nerve pathways involved in muscle control and awareness — something standard vibration often doesn’t reach.
How do I clean Senza?
+
After use, you can easily clean Senza with warm water and mild soap. The material is non-porous, which means bacteria cannot penetrate the surface. Let it air dry or gently pat dry with a soft cloth.
Is Senza quiet enough to use in a household?
+
Yes. Senza operates discreetly (under 40 dB), comparable to a soft whisper. You can use it comfortably while others are in the house.
How long does the battery last?
+
With normal use, the battery lasts on average 2–3 weeks (depending on intensity and frequency of use). Charging is done via magnetic USB-C and takes approximately 90 minutes.
Can I use Senza in the shower or bath?
+
Yes. Senza is fully waterproof (IPX7), so it’s safe to use in the shower, bath, or even a warm bath.
Can I use Senza with a partner, or is it only for solo use?
+
Both are possible. Senza can be used solo for pelvic floor training and sensation, but also during intimate moments with a partner — as long as it feels comfortable for you.
How often should I use Senza?
+
We recommend starting with 2–4 times per week, 15–20 minutes per session. Many users notice clear improvements within 4–8 weeks of consistent use.
Is Senza a replacement for pelvic floor physiotherapy?
+
Senza is a powerful addition to pelvic floor training, but it does not replace medical advice or physiotherapy. If you have ongoing concerns, we recommend consulting your physiotherapist.
Is Senza shipped discreetly?
+
Yes. All orders are shipped in neutral, unbranded packaging without product names or explicit imagery. The outside only shows a general business name, with no reference to the product.
