600+ deep muscle contractions a session. Zero effort from you. No refills, no replacing, nothing to maintain. Just strap in and let clinically proven NMES take over.
The MuscleLabs Ultra Stimulator is an NMES (Neuromuscular Electrical Stimulation) device that straps around your core. It sends targeted electrical pulses through your skin directly into your core muscles, forcing them to contract and release automatically — the same movement pattern as a crunch, plank, or sit-up, without you moving a muscle.
Each session runs twenty minutes. In that time, your core fires 600+ contractions — the equivalent of over 3,000 crunches, done for you.
You're in full control. A built-in module gives you 12 clinically developed modes and 19 intensity levels, so every session can be dialed in exactly how you want it. Modes change the rhythm and pattern of the contractions; intensity levels let you decide how deep they go, from a light pulse to a full, powerful contraction.
Using it couldn't be simpler: strap the belt around your core, pick your mode and intensity, and hit start. No pads. No gels. No mess. It sits flush against your skin and stays locked in place, completely hands-free.
Why Customers Choose Us
Plenty of brands sell devices that look like the Ultra. Same shape, similar packaging, cheaper price. But looking the same and performing the same are two very different things.
The Ultra Stimulator isn't a copy chasing a trend — it's the original, refined three times over since launch. Every iteration pushed the contractions deeper, the fit more comfortable, and the device more reliable for the long haul.
What you're holding today is the result of three generations of real-world testing and improvement. A knockoff can replicate the outside. It can't replicate the engineering that went into what's under it.
Here's what sets it apart:
Three generations of refined technology — every version built on real feedback, not guesswork
Deeper, stronger muscle contractions, engineered for actual results — not just a buzzing sensation
100% hands-free — strap it on and go about your day
Built to last for years, not months
A knockoff can copy how a product looks. It can't copy three generations of engineering behind how it actually works.
Because finding time for yourself shouldn’t feel like another thing on your to-do list.
Between work, family, plans and everything in between, fitting another workout into your day isn’t always realistic.
That’s why we created Muscle Labs — an easy, hands-free way to add targeted muscle stimulation to your routine, whether you're focusing on your glutes, abs or thighs.
Use it while you work, unwind or watch your favourite show. Your routine, your time.
This Is What 20 Minutes a Day Looks Like
Real transformations using NMES for only 20 minutes a day, 100% on autopilot.
★★★★★
The first thing that actually flattened my stomach.
I’ve been using the ab one while I’m watching TV at night and I’m genuinely surprised by how much you can feel it working 😂 I started on a low setting but I’ve slowly worked my way up. My core definitely feels more engaged and I love how easy it is to fit into my routine.

★★★★★
Seeing such a big difference!
Okay the glute one is STRONG 😂 I honestly wasn’t expecting to feel the contractions that much. I use it on days I’m not training and I love that I can literally sit on the sofa while it’s doing its thing. Definitely my favourite one.
Lucy M., 2 Weeks Use
★★★★★
Incredible results! I noticed improved muscle toning almost immediately.
I originally only wanted the glute stimulator but ended up getting the bundle and I’m so glad I did. The glutes are still my favourite though! It takes two seconds to put on and I can actually feel the muscles contracting throughout the whole session. So easy to use and has become part of my routine
