I am a professional freediver, and that “pro” label is not just a title.

It is a daily commitment to breathing work, CO₂ tolerance, hypoxic adaptation, diaphragm stretching, breathing muscle mobility, residual volume reduction, packing, reverse packing, full-lung stretching, and all the other weird little rituals that come with chasing depth.

Name it, and I have probably done it.

I am always looking for new knowledge, new methods, and new tools that can make me a better instructor, a better diver, and help me stay longer, dive deeper, and feel more relaxed underwater.

For years, my focus was simple:

Stretch everything.

I wanted bigger lungs. I still do. Oh yeah, they are never big enough. I wanted more air in the tank, more comfort at full inhale, and more freedom in the ribcage and diaphragm.

Because in freediving, size matters.

But stretching only creates space. It does not automatically give you the strength to use it.

That is when Airofit first entered my routine.

A few months ago, I received an email from Airofit about their new model: Airofit Elite.

So I thought:

Let’s give it a go.

I wanted to see how far they had taken the concept, and whether Airofit Elite could earn a place in my training routine.

Not only as a freediver chasing better control underwater, but also as an endurance athlete trying to make breathing stronger, cleaner, and less expensive.

What Is Airofit Elite?So what is Airofit Elite?

So what is Airofit Elite?

In simple terms, it is a smart respiratory muscle trainer.

You breathe through the device while it creates controlled resistance. Your breathing muscles have to work against that resistance, just as your legs work against pedals, your arms against weights, or your back against a pull-up bar.

The concept is simple.

Airofit Elite makes it structured, progressive, and measurable.

The device has a mouthpiece with a built-in sensor, adjustable resistance for both inhalation and exhalation, Bluetooth connectivity, and an app that guides the session.

The app is where the training becomes more interesting.

It includes lung function measurement, precise breathing detection, personalized training programs, adaptable breathing exercises, live feedback, and progress tracking. And honestly, all of that is useful.

These features make respiratory training more organized and more precise.

The lung function test gives you a starting point. The breathing detection helps the app read what you are actually doing. The personalized programs give direction. The live feedback helps you correct the session as it happens. The tracking gives you a reason to come back, because improvement comes through consistency.

Airofit also offers an Elite Premium subscription with extra guided programs, advanced statistics, and training insights.

I am usually suspicious of subscriptions, because apparently, everything now needs to charge you every month just to keep existing.

But here, I can see the point.

What interests me most is the sport-specific training. Premium includes programs for running, cycling, swimming, triathlon, recovery, and more.

Since my training is now split between freediving and 70.3 preparation, I'm curious. I am seriously thinking about giving it a try, and I will keep you updated.

Breathing in and breathing out are not the same job.

They do not use the exact same muscles, and they should not be trained as if they do.

Inhalation primarily challenges the diaphragm and inspiratory muscles. It involves expanding the chest cavity, creating negative pressure, and drawing air into the lungs.

Exhalation, especially when trained with resistance, is more active than most people realize. It engages the abdominal muscles, intercostals, and coordination. It becomes important for forceful exhalation, recovery breathing, and control under fatigue.

Most basic breathing resistance tools ignore this distinction.

They simply make breathing harder.

That can still be useful.

But harder is not always smarter.

Airofit Elite allows you to adjust resistance separately for inhalation and exhalation. This means you can target specific weaknesses, build more balanced respiratory strength, and train with intention instead of randomness.

You are not just “breathing harder.” You are training specific functions.

You can increase inspiratory resistance to challenge the diaphragm and inspiratory muscles.

You can increase expiratory resistance to improve active exhalation and breathing control.

You can progress gradually, just like you would in the gym.

Airofit Elite Is Not a Gadget. It Is Training Equipment.

Because breathing training can become vague very quickly.

You feel something.

But feeling is not always progress.

Assumptions are not results.

Airofit Elite turns the process into a loop.

You test, train, and track.

You see what changed, then repeat the process.

That matters to me because I already track my pace, heart rate, distance, recovery, and how my body responds.

So if I am going to add respiratory training to my freediving and 70.3 preparation, I do not want another random ritual.

I want to know if my respiratory strength and vital capacity are improving.

I want to know if the time I invest is actually useful.

That is the real promise of Airofit Elite:

to turn breathing into structured, progressive, measurable training.

Of course, a promise is easy to make.

The real question is whether it actually delivers.

My Verdict After a Month and a Half

So… does it actually deliver?

For me, yeah.

I have been training with Airofit Elite for 5 weeks now, and I am thrilled by my progress. My vital capacity is up 21.46%. My inspiratory strength is up 50%. My expiratory strength is up 91.5%.

These are my personal results after these few weeks of use. Your numbers may differ, and like any training tool, Airofit Elite only works if you use it consistently.

But more importantly, I feel it in the water.

I feel better. Stronger. Sharper.

When I take a full breath now, I literally think:

“Oh yeah, that feels good.”

That does not mean Airofit Elite is some kind of magic solution. I am still doing everything else on the side.

But as respiratory muscle training equipment, I love it.

The combination of a lung trainer and a virtual coach is what makes the difference for me. I finally found a simple, efficient way to train my breathing muscles without turning it into another huge time investment: 10 minutes a day, structured, measurable, and easy to repeat.

We all want to know whether the hours we invest in training are actually paying us back. With Airofit Elite, I can see it. It is not only based on feeling. It is backed by measurable data.

I am convinced freedivers should not forget to give their breathing muscles a proper workout.

And Airofit Elite is definitely the best choice on the market right now.

Go give it a try.
