We spend countless hours training our legs, core, and endurance... but what about our lungs?

Did you know there’s a secret technique to surge your athletic performance by 8% in as little as 8 weeks without having to spend ANY EXTRA TIME IN THE GYM? 

What's more, instead of putting in extra hours training and pushing your body to even more extreme limits than you already do, this under-utilized method actually requires you to spend more time RELAXING!

SO WHAT IS THIS SECRET METHOD TO GAINING A COMPETITIVE EDGE ?? 

It’s an exciting new device called AIROFIT BREATH TRAINER...

... an intuitive Bluetooth connected mouthpiece that utilizes Respiratory Muscle Training (RMT) so  that: 

  • Exercise feels easier
  • Training is more enjoyable
  • You can train harder with the same effort
  • You can train longer with the same effort
  • Evidence-based improvement in performance (4 minutes of RMT could yield as much as a 4% improvement in time trial performance)
  • The most time-efficient, evidence-based ergogenic training adjunct available

Airofit allows you to train your lungs with the same expert precision as if you were working personally with an athletic respiratory coach.

WHAT IS RMT (Respiratory Muscle Training)? 

Respiratory Muscle Training (RMT) can be defined as a technique that aims to improve the function of the respiratory muscles through specific exercises. It’s known to have numerous health benefits, particularly for stress relief and some lung-related conditions, but, as athletes, what we really want to know is: will it make me go faster or boost my endurance?

The science (links to multiple studies found at the end of this page) plus testimony from professional athletes and my own personal experience says: YES

What's more, while evidence is piling up on the benefits of RMT for enhancing athletic performance (particularly in endurance athletes), respiratory training is still one of the most overlooked techniques in all of sports- which means you can enjoy a real competitive edge (with remarkably quick results) by practicing RMT, particularly through Airofit breath trainer's advanced technology.

WHAT IS AIROFIT? 

Airofit is a new training device from 🇩🇰 Denmark that's being used by athletes of all levels to improve their breathing. In as little as 8 minutes per day, while resting, you can boost your lung capacity and your anaerobic fitness.

Airofit has two parts: The patented Breath Training Device is a comfortable mouthpiece with pressure sensors that you breathe into and The FREE Airofit Training App (iOS & Android). The mouthpiece is Bluetooth connected to your phone wich allows you to visualize each inhale and exhale in the Training App in real-time.

The Airofit Training App walks you through daily workouts, telling you when to inhale, exhale, hold your breath, and more. All the lessons are based on proven training protocols to boost your respiratory performance. The app makes the training very easy to follow even if you have never done breathe training before. 

Once you have mastered one level, the app will tell you to adjust the dials on the side of the Breath Training Device adding resistance to make it harder to inhale, exhale, or both. This trains and strengthens your lungs over time, just like any other muscle. 

In as little as 3 weeks, most athletes see noticeable improvements in their primary sports.

Do you have 10 minutes a day to be better at your sport?

Praised as a ‘game-changer’ by professional European athletes from all types of sports, such as Peter Larson (triathlete), Michelle Vesterby (triathlete), Ekaterina Avromor (professional swimmer), Amalie Wither (cyclist) and many others

 If you're like most serious athletes you're probably already doing as much as your body can handle or schedule will allow for your training. What I love about Airofit is that it doesn't take additional energy or add more fatigue to your body and in only 10 minutes a day, you can see significant athletic improvements. Plus lesser trained athletes will see even greater gains than professionals. 

I've been using Airofit for the past 60 days and it has transformed the way I breathe while running and cycling. Here's what it's done for me:

Increased my total lung capacity

This means that more air can get into your lungs to be utilized by the muscles. How? Stretching your diaphragm and intercostal muscles allows you to decrease the residual volume and increase the amount of usable air.

Strengthened my respiratory muscles.

Think of this as endurance work. With most of the focus on the diaphragm, endurance athletes can benefit from respiratory trainers because it will prolong the time until we fatigue, which prolongs the oxygen supply to motor muscles.

Boosted my anaerobic capacity

My ability to maintain maximum efforts for longer. This was the feature that absolutely sold me on Airofit. Any training tool that can improve my anaerobic tolerance is a product that I can get behind.

Just so there is NO Confusion, you do NOT use Airofit while running, cycling, or working out. You use it before or after your training when you are at rest.

How To Use Airofit:

What's remarkable is how simple it is to use. You put the mouthpiece in your mouth and turn it on. It automatically connects to your phone. You then start the different workouts and training programs in the app, following the instructions on when to breathe in, when to breathe out, and in some of the training programs when to hold your breath and for how long.

Another cool feature is that you can see in real-time the breath you are taking in the app. It will say "breath in" at a certain rate and, if you go too fast, your inhalation line jumps way above the recommended line. The goal is to control your breathing to keep your breath inline with the recommendation line to complete the workout.

Does it work?

The experience from the first athletes using Airofit is almost too good to be true, but the research does back up the findings of these athletes (links to studies at bottom of page).

In as little as 4 weeks, athletes are seeing significant improvements in their ability to inhale a greater amount of oxygen and as a result, boost endurance and the time they can sustain maximum anaerobic efforts.

The best part is that it takes under 10 minutes per day. It won't interfere with your regular training or make you tired. Plus you can do it almost anywhere.

Is it only for Pro Athletes?

While super-elite athletes will certainly benefit significantly from Airofit training, the data and past research suggest that slightly less trained athletes will benefit even more from training with Airofit.

How the training app works.

The secret sauce for Airofit is the training program in the app (iOS & Android) that guides you through different lung workouts each day. They're set up as a progression and as you get better at each session, the app increases the difficulty using the adjustment rings on the mouthpiece.

My Personal Experience: 

The first sessions I did were really challenging. I thought, "I'm never going to be able to do this". It was amazing how BAD I was at them. But I stuck with it and in only a few days, I could already feel the training working and the sessions got easier and easier even as  the the app increased in difficulty!

Just like with any training, when you work on your weaknesses you see huge improvements quickly. After just the first 4 weeks I was ecstatic with the improvements I made.

The basic components of the training sessions are as follows:

  1. Respiratory Strength is going to improve your exhale strength, massively. The training is focused on strengthening your diaphragm so that you inhale and exhale more air in a given amount of time. 
  2. Anaerobic Tolerance will teach you how to exhale and then hold your breath; it’s more of hypoxic training when you consider it all. Studies show that prolonged breath-holding induces additional blood vessel growth, which significantly boosts muscle oxygenation. This prolongs the period in which you stay within aerobic metabolism, reducing lactic buildup, which allows you to perform at higher intensities for longer. Not to mention, hypoxia directly correlates to reduced heart rate, which increases time to exhaustion, but more importantly, a greater ability to withstand extremely hard and extended efforts.
  3. Vital Lung Capacity allows you to both inhale and exhale more air, improving your body’s oxygenation, your efficiency with every breath, and your endurance. This is really a residual benefit from the Respiratory Strength training

Relaxation, a bonus benefit

A lot of us endurance athletes are go-go-go type of people. Personally,  I’ve never been good at sitting still- even though my wife's been trying to get me to meditate for years. I'll give it a shot but I have a tough time settling in and 'letting go' of my thoughts.

Since using Airofit, I've found I'm getting the mental and emotional benefits of meditation and deep breathing using a logical, data-driven system I can work with! Even though you can use Airofit for just 8 minutes a day for great results, I like to use it in the morning for strengthening and conditioning my lungs and then again at night before bed to get me into a super relaxed state for sleep.

Great for traveling

Airofit is also super-portable. It’s great to take with you while traveling and when you know your training schedule will be lighter you can plan to do longer sessions to keep your lungs in top condition. And, if I ever skip a workout, (hey, it happens!) doing an Airofit is a great way to get over the guilt and know I'm still something to improve my performance.

I DEVOURED this book. I was in a huge slump after reading a horrible series right before this but after 3 pages of this book, I was hooked. I read the whole book in 2 days. I think the author did an amazing job at writing an engaging story with an amazing twist at the end. I know many readers feel betrayed by the twist and find the narrator to be unreliable but I feel that the twist was done in a great unsuspecting way. Though I do feel betrayed, I think there is so much room for redemption in the second book! The author also did an amazing job at world/character building. She was able to do so without interrupting the story which is one of my huge pet peeves. A lot of authors build by taking breaks in the plot or dialogue which I find choppy and disengaging but this author was able to build in an engaging way. There was some lack of world/character building but I think that was due to keeping reader in the dark. The world, politics, and characters were all very easy to understand. I found the romance a little lackluster and a bit off-kilter. Some of it was really pushy and rushed which left a bad taste in my mouth. I do hope the author delves deeper into the romance in coming books. The FMC was a breath of fresh air. She was not whiny or stuck-up like most books. She was never afraid to accept help from others but she was still able to shine with her intelligence. Not once did I think she made a poor decision just for the sake of a plot point. She was really easy to like. The MMC could use some work but I think that will happen more in coming books. This is a MUST read, my only advice would be to wait until it is a finished series!

Need book 2 please :-)
Format: Kindle
From the very first chapter, Metal Slinger hooked me and refused to let go. Set in a brutal, metal-bound world where power is carved from steel and survival depends on strength, strategy, and sheer will, this story follows a young woman forced into a dangerous system where control over metal isn’t just magic — it’s dominance, protection, and rebellion. When she’s pulled into escalating conflict and shifting alliances, she quickly learns that power always comes with a cost. The magic system is sharp and immersive without being overwhelming. The way metal manipulation is woven into combat and politics makes every confrontation feel cinematic and high-stakes. It’s gritty, tense, and beautifully layered. The Brynn, our FMC absolutely shines. She’s fierce but not untouchable, resilient without feeling unrealistic. Watching her navigate betrayal, survival, and the slow awakening of her own strength felt earned every step of the way. There’s grit in her fight scenes and vulnerability in her quieter moments that make her deeply human. And the tension? Immaculate. The chemistry simmers under the surface before sparking into something electric. Every reluctant alliance, every charged interaction, every moment of “are they about to destroy each other or kiss?” had me flying through pages. The pacing is relentless — no filler, no wasted scenes. Twists land hard. Stakes keep climbing. And that ending? Absolutely feral. The kind that leaves you staring at the wall for a minute before immediately checking when book two releases. ✨ Gritty metal-based magic ⚔️ High-stakes survival 🔥 Slow-burn tension 🖤 Fierce, layered heroine 💥 A finale that HITS (but cliffhanger!) This is one of those fantasies that reminds you why you fell in love with the genre in the first place. If this is just Book One, I am more than ready to be emotionally wrecked again in the sequel.

Read this book! Then join our support group for the ending😜
While I’ve read some amazing books this year, it’s been awhile since I have completely devoured a book in less than 24 hours. This book was one I truly could not put down. I couldn’t fall asleep because I didn’t want to stop reading what happened next. The way this book starts is one of my absolute favorite ways to fall into a story - with no preamble and immediate conspiring amongst characters. Brynn has quickly become one of my new favorite FMCs. She is just so REAL. No whining or blaming her situation on everyone and everything else. She accepts her role in the world, but also holds a fierce determination to know the truth of that world. She is brave, yet terrified. Strong, yet self-conscious. She is cunning and intelligent and she doesn’t shy away from what is hard or allow emotion to overcome logic. I feel like she’s such a relatable character in everything that happens to her. Then we have Kai…our commander and son of the leader. He’s got secrets. Big ones. And the amount of times my feelings for him flipped in this book is insane. I’m still honestly reeling… Acker, my man…he’s mysterious, yet he doesn’t pull his punches. He’s loyal to a fault. He feels things deeply and he is fervent in his beliefs and desires. I adore him and yet want to shake him for the way he goes about making decisions and only sharing half truths. And right now my heart is aching for him and also terrified of him. When I say I need book 2 like I need water, that’s an understatement. I don’t have space to discuss every side character, but just know that I love them deeply and they each have big personalities of their own. The miscommunication honestly feels more like a necessity and less of a trope. The MCs don’t truly know one another, so of course there’s hesitancy to share everything with a stranger who has been somewhat forced upon you due to the situation you’ve both found yourself in. But it also is refreshing to watch them both learn to trust and communicate more and more as they go. The world building was exciting and unique - unlike anything I’ve read before. The kingdoms and their systems and the unique magics all create this setting that is utterly perfect. I never felt confused, but could easily envision everything as it was explained in detail. The slow burn and spice was paced so perfectly and realistically that it never felt weird or forced or annoying. It unfolds the way most normal relationships would (minus the magic and fantasy aspects). I truly cheered for our MCs and loved the way they finally came together. This story takes all the tropes we know and love and twists them into something unique and entirely different than all the other stories we’ve grown used to. And when I tell you that you will NEVER see the plot twists coming, HOLY SMOKES BATMAN! And the last 2 chapters took me ALL THE WAY OUT. I’m not sure how I’m supposed to be okay after that. I almost want to go back to chapter 55 and pretend the rest didn’t happen…but of course I can’t do that and now I’ll just be dying a little inside every day until I get my hands on book two! If you enjoy fantasy or romantasy, this has to be your next read. All the rest can wait. Grab your copy YESTERDAY.

Outstanding book - A MUST READ
This is fantasy romance at its finest, and I couldn’t put it down from the moment I started. Packed with classic romantasy tropes that are done so well, especially my favorite: fated mates! The world-building is both easy to digest and detailed enough to feel immersive. It strikes the perfect balance—not too vague but never overwhelming. The world is divided between several groups of people, and the story revolves around the Alaha, who live on the water, and the Kenta, who reside on land. For centuries, these two factions have maintained a fragile peace, but things take a sharp turn when our FMC, Brynn, threatens that peace right at the beginning of the book. What follows is a thrilling dive into a world of magic, rebellion, and secrets. I will say no more, because you should go into this book relatively blind to get the full experience. Brynn, our FMC, is everything you could want in a lead. She’s smart, confident, and refuses to bow to threats. Then there’s the MMC, Acker. Scrumptious doesn’t even begin to cover it. The chemistry between him and Brynn is electric, and their dynamic had me grinning (and swooning) throughout. This book has all the best romantasy tropes: forced proximity, slowest of slow burns, elemental magic, fated mates (done right), political intrigue, and plot twists you will not see coming! Each trope is executed masterfully, blending seamlessly into the story without feeling overdone. If these are your jam, you’ll absolutely love this book. Even if they are not usually your cup of tea, this book may change your mind. While the pacing is fast and gripping overall, it does have a bit of a lull in the middle. That said, the ending more than made up for it—it left me gasping and desperate for the next book. I think I said aloud, “What the hell just happened?” when I finished the last page. This book grabbed me by the neck and didn’t let go. It’s full of banter, twisty turns, and a delicious tension. Probably one of my favorite fantasy reads this year. I am going to be thinking about this book non-stop until book 2 is released!

Cool world building and great side characters
Format: Kindle
I adored the side characters and found them a lot more compelling than Jovie and Acker, if I’m being honest. I really wanted to like her but I found myself getting frustrated by her lack of, I don’t know, real rage for any of the crap people pull on her. Like ok I get this is romantasy but I have a hard time really believing you’re actually as upset at this guy as you claim to be when two minutes later you’re letting this dude shove his tongue down your throat. Additionally, an early running theme is that Jovie is frustrated that there are a bunch of people deciding things for her but the existence of the whole “matched/bond” thing makes much of her autonomy a moot point. Like at one point I think Acker even points out that them getting into bed together is a “foregone conclusion” and someone else mentions that the other matched pairs that don’t end up together ended up literally destroying each other. No pressure. I was a lot more interested in the characterization of Messer, Beau, and Hallis. I knew I was going to be exasperated consistently by this girl when she let Mr. Murder Hottie treat Messer like a war criminal after he almost got himself spatchcocked for them by a mighty-morphing radical with an attitude problem. If my homie went through the battle blender like that for me after I found out he had been secretly protecting me and keeping me company for weeks/months, I would be doing A LOT MORE than standing around trying to figure out if I actually thought he was my friend while Captain Boy Toy did some light torture on him. Also Acker, my dude, if you can still find it in your heart and your loins to get riled up while your sister is having a breakdown in the room over…I don’t know, seek help I guess. I liked the juxtaposition of Beau’s bravado and her militaristic delivery of information to her brother showing she can turn on a dime when needed. Adding the mental toll her gift takes on her throughout time and how she has self destructive coping mechanisms really gave her some cool depth, and I appreciated the vulnerability it lent her. Hallis was a weird character for me at first but I ended up looking forward to his dialogue a lot. Initially, I didn’t care for the way he seemed to immediately just be a real jerk to Jovie and it didn’t often read as playful to me when I think it sometimes meant to. Regardless, his genuine care for Beau and Acker and how he dropped the act immediately when they really needed him made him pretty endearing and I always appreciate a grump who cares. Honestly everything about this book was an A+ for me aside from the two main characters’ dynamic. When Jovie gets pissed at those bats and obliterates a forest? A+ When she tells Acker that she saw the signs that Messer was getting abused and acknowledged she felt shame and that she couldn’t fault him for being complicit in her mistreatment since she had done the same? A+ When she’s sitting there and coming to terms with the fact that everything she knows has been built on lies as she’s flipping through her sketchbook? A++ The writing and setting is great and the book is good, but someone needs to give Jovie a big stick and tell her it’s okay to be mad and smack people with it even if they’re hot.
