THE LAB – Airofit PRO 2.0 – Do you really need to train your lungs??

We exercise every muscle, so why stop at the respiratory muscles? That’s exactly the question that inspired the Airofit team to develop the respiratory muscle trainer Airofit PRO 2.0. We tested the small training device and accompanying training plan to find out whether it really works, or if it’s all blow and no go.

At first, training the respiratory muscles may sound strange. After all, aren’t they naturally trained through exercise, just like the heart muscles? To some extent, yes: endurance sports can increase lung volume, but their impact on the respiratory muscles themselves is rather limited. This is where training equipment like the Airofit PRO 2.0 comes into play, by targeting and strengthening these muscles. The concept behind it is that by breathing in faster and harder, more air passes through your lungs, resulting in increased oxygen intake into your blood, which is crucial for athletic performance. We thoroughly tested the Airofit PRO 2.0 training device, along with its app and the premium package, priced at € 349. Is it worth the high price tag, or is it merely a marketing gimmick?

The Airofit PRO 2.0 breathing trainer in detail

The breathing trainer from Airofit follows a simple principle. Paired with the right app, the training can be monitored and individually adjusted. But how does the training actually work?

In order to influence the resistance during breathing, the device must be inserted into the mouth: this means it’s mouth-breathing time, folks! Two valves on the sides determine the resistance when inhaling or exhaling. A simple twist mechanism allows them to be intuitively adjusted in six steps, ranging from fully closed to fully open. The accompanying e-unit measures the strength, duration, and pauses between exhalation and inhalation, and relays the information to your phone via the Airofit app.

The device can be disassembled for easy cleaning and extra mouthpieces in different sizes can be added for a better fit. The e-unit, as the only electronic component, is waterproof and charged via a magnetic plug. The simple construction and the decision to use plastic with a rubber coating make the appliance more hygienic, but it does leave a cheap aftertaste. It’s a bit of a shame, especially considering the price, that the device doesn’t come with a higher-quality finish.

On the other hand, the app is intuitively designed, connects quickly with the Airofit PRO 2.0 and provides useful insights into the training of your respiratory muscles. Unfortunately, unlocking all of its functions requires a subscription. Considering the initial purchase cost, this made us raise an eyebrow.

Clever solution!
The valves for inhalation and exhalation can be adjusted in 6 steps to find the ideal resistance for your breathing training.
Simple, but well thought out.
The rotary control on the valve makes it easy to adjust. The levels are numbered from 1–6 to indicate the resistance during breathing.

It’s the app, with all its functions, that truly maximises the device’s performance. Upon first use, it creates a profile by inquiring about your training background, favourite sports, and training goals. Following this, you have to conduct an initial lung function test. This test measures vital parameters such as lung volume, maximum inspiratory pressure (the highest pressure experienced during inhalation), and maximum expiratory pressure (the highest pressure during exhalation). The maximum inspiratory pressure provides insights into the strength, flexibility, and efficiency of your respiratory muscles during inhalation. Likewise, the maximum expiratory pressure acts as a gauge for the strength of the muscles during exhalation.

The test may feel strange the first time you try it, but you get the hang of it very quickly. We recommend repeating the initial test a few times in order to obtain meaningful values. Once completed, your individual training begins. The Airofit app suggests different training sessions every day, which not only alter the resistance settings on the device, but also adjust the duration and intensity of your inhalation and exhalation. Additionally, the app tracks and counts air-holding periods between sessions.

Everything you need.

Breathing training with the Airofit PRO 2.0: Is it worth the hype or does the device run out of breath?

The app records the daily training and measures the progress. Particularly in the initial stages, we observed significant improvements across all measured data. However, it’s hard to attribute these changes exclusively to the training itself or simply adjusting to the device.

In everyday life, we’ve also noticed tangible progress and that we don’t get out of breath so quickly. Of course, the training also draws specific attention to your breathing. Obviously, the Airofit is not a substitute for sport, but it will strengthen your respiratory muscles. The real benefit of Airofit compared to cheaper alternatives from other manufacturers is the app and the smart integration of the e-unit. However, these benefits come with a hefty price tag.

Diving gear?
The mouthpiece of the Airofit PRO 2.0 is reminiscent of diving equipment but fits well and can be replaced if necessary.

Airofit PRO 2.0 is a cool gadget focusing on an often overlooked area of training. It adds real progress to training and promotes your performance, but it is not a substitute for physical exercise. At the same time, it is not only of interest to people who are enthusiastic about sports. The app’s high price and the functions at a surcharge are somewhat off-putting and not justified compared to cheaper alternatives.
