★★★★★ 4.9/5 — 577+ reviews

You've done everything right.
So why do you still wake up stiff?

You track your sleep. You manage your training load. You eat well and recover hard. But every morning, you spend the first half hour just trying to get loose. Most athletes never find out why. Reviv is built for the ones who do.

Chapter 1 — The problem they can't solve

You've ruled
everything out.

You've tried more sleep. You've tried less volume. You've worked on your posture, stretched more, added recovery sessions. Some things helped a little. But the morning stiffness — the tight neck, the locked upper back, the first 20 minutes of every day spent just loosening up — never fully went away.

That's the pattern most athletes accept as normal. Part of the sport. The cost of training hard.

It doesn't have to be.

Chapter 2 — The discovery

The variable
nobody tracks

Your jaw is anchored to your skull by the same soft tissue network that runs through your neck, your upper back, your spine. When your teeth come together during sleep — which they do, for most people, without you knowing it — that contact creates tension that doesn't release until you're up and moving.

It's not a training problem. It's not a sleep problem. It's a jaw problem. And almost nobody is looking there.

This is the connection Ken (EGK) identified — and why he built the R3.

The mechanism

How jaw position creates morning tension —
and how supporting it changes things

The R3 is built to stretch the soft tissue and allow the jaw to naturally move where it wants — during sleep, while reading, while winding down.

When the jaw is free to decompress overnight, the tension that normally travels up through the neck and upper back has somewhere to go. Many athletes who start using it consistently notice the mornings shift — not dramatically at first, but reliably, over time.

Less time spent loosening up. More range of movement from the start of training. A body that feels like it actually recovered.

Results vary. The R3 is designed to support natural jaw positioning during sleep.

Chapter 3 — The shift

What changes when you
add this to your routine

The R3 doesn't ask for extra time. You wear it while you sleep — that's it. No new protocol. No extra session. No change to anything else in your stack.

What changes is what happens to your jaw during those hours. And when your jaw is no longer creating overnight tension, your neck and upper back start the day from a different baseline.

Some people notice it within the first week. For most, the shift becomes consistent after two to three weeks of regular use. The mornings stop being something to manage.

Individual results vary.

Athletes who found
the variable they'd missed

★★★★★
“I'd been waking up stiff for years — thought it was just part of training heavily. Someone mentioned jaw tension and I was curious enough to try Reviv. About a month in and the mornings are noticeably different. I don't spend nearly as long trying to get my neck and shoulders loose.”

“Took me a couple of weeks to properly adapt to sleeping with it, but once I did I started noticing less tension in my jaw when I woke up, and my neck felt less locked. I train six days a week and this has become a non-negotiable part of winding down.”

Chapter 4 — The new normal

What athletes who use it consistently say

★★★★★
“I've used a lot of recovery tools over the years. Most of them I cycle in and out depending on what I'm prioritising. The R3 is the one thing I haven't put down. I use it every night — it's quiet, it's simple, and the difference in how my mornings feel has been consistent for four months now. At this point it's just part of how I recover.”

★★★★★
“I was the person who spent the first 30 minutes of every morning just trying to feel normal before I could train. I didn't connect that to my jaw at all — it seemed too indirect. After six weeks with Reviv, that window is much shorter. My neck doesn't lock up the same way. I wish I'd looked into this a lot earlier.”

“Simple to use, easy to get used to, and it does what it says. I travel frequently for competition and I take it everywhere. The consistency of my mornings has improved in a way I can't put down to anything else.”

The R3 — built for athletes
who leave nothing to chance

Reviv R3 benefits

The R3 is a structured mouthguard made from a flexible material designed to fit comfortably in your mouth. It's built to stretch the soft tissue and allow the jaw to naturally move where it wants — during sleep, while reading, while winding down.

Unlike standard mouthguards built to guard or hold the jaw in place, the R3 works by releasing the anchor points where teeth connect — allowing the jaw to decompress during rest rather than stay locked in tension.

No boiling. No moulding. No adjustment required. Ready to use from night one. Most athletes adapt within the first few nights and integrate it into their wind-down routine without friction.

Designed to support natural jaw positioning. Not a substitute for professional care.

Reviv Founder Ken Leaver

Why Ken built this

Ken (EGK) developed Reviv after discovering that his sleep, recovery, and energy were improving — without any change to his training. He traced it back to jaw position. The R3 was built from that discovery: a tool for athletes who have optimised everything else and are ready to look at the one variable they haven't touched yet.

Questions before you try it

The R3 is designed for overnight use — wear it while you sleep. Some people also use it during low-activity downtime like reading or winding down before bed. The longer it's in, the more opportunity the jaw has to decompress.
Many people notice a change in how their jaw feels within the first few nights. Changes in morning stiffness and neck tension tend to become more consistent after 2–3 weeks of regular use. Individual results vary.
The R3 is made from a flexible material that sits lightly in the mouth. Most people adapt within the first few nights. It's designed for consistent overnight use — not a bulky guard that disrupts sleep.
No. The R3 requires no boiling, moulding, or custom fitting. It's ready to use out of the box.
Yes — the R3 is designed to complement your existing recovery stack, not replace any part of it. It adds a recovery input that works passively while you sleep.
The R3 is designed to stay in place during normal sleep movement. Most people find any initial adjustment resolves within the first week.
The R3 is backed by a Satisfaction Guaranteed policy and a 1-Year Warranty. Support is available if you have questions.
