"Eisenkurt" - Stronger than ever at the age of 74

Records, regeneration and new energy: extreme athlete Kurt Köhler has been relying on Airnergy for 20 years

How fit can you be over 70? Eisenkurt shows us!

Kurt Köhler, known as "Eisenkurt" or the "Bavarian Popeye", is not just a phenomenon in the fitness world - he is a real exclamation mark when it comes to regeneration and vitality. At 74, he has the blood values and biological age of a 25-year-old. His energy? Unbroken. His performance? Still world record-breaking!

Airnergy as the key to top performance

Eisenkurt has been relying on Airnergy's spirovitalization technology since 2005 - and attributes a large part of his endurance performance and in particular his ability to regenerate to precisely this technology. The almost daily use not only helped him to regenerate quickly, but also provided the decisive increase in energy for his famously exceptional athletic performance.

In May 2025, as part of the "New for Old" campaign, he received the new Airnergy Professional Plus Compact model - a further development of the tried-and-tested classic Professional Plus Vitalizer, which had been with him for a good two decades.

World records with an announcement - and breathing technology with living air

In 2023, he also made people sit up and take notice with a boxing world record: 40,140 power boxing punches in 2 hours and 39 minutes - an official record under the supervision of a referee.

But that was not the first milestone: 20 years ago today, Köhler set a world endurance record at the 24-hour race at the Nürburgring in 2005. Using a 45-degree leg press, he moved an incredible 5,000 tons of weight within 8 hours and 51 minutes - accompanied by Airnergy, TV teams and enthusiastic spectators.

Training, breathing, regeneration - the recipe for success

What sets Köhler apart is not only his physical strength, but also his consistency and endurance: for years, he trained daily, combining martial arts, endurance and strength training and cycling like no other - and relied on Airnergy at the same time.

The results speak for themselves: better regeneration, more energy, less fatigue, more endurance - and a body that looks decades younger than its actual age.

Lively air with Airnergy for all ages - not just for extreme athletes

"It was during the pandemic and the associated mask-wearing that I first really realized how valuable and without alternative our breathing air is," explains Kurt Köhler today. For this reason, and because of all the impressive results in both healthy and sick people, he is now actively supporting the further spread of the Airnergy method in Munich and throughout Bavaria and beyond.

His conviction: Spirovitalization is not only suitable for athletes, but especially for people with functional or organic disorders and of all ages with brain fog, burnout or chronic fatigue syndrome (CFS) who want to take more responsibility for their health, vitality and quality of life and that of their family.

A strong duo - also in the future

After more than 20 years of working together, Eisenkurt is convinced: "Airnergy has opened up a new dimension of performance for me and this is exactly what I want to benefit other people and pass on. I am delighted to be able to take off again together with Airnergy and bring this excellent air/atmosphere into the world!"

Airnergy International GmbH:
A good 25 years of experience in health biotechnology

Originating from natural energy solutions AG, which was founded in 2000, Airnergy AG and its parent company Airnergy International GmbH, based in Hennef near Bonn, were the first developers to bring the Airnergy vitalization devices to market. This unique health technology improves energy production and oxygen utilization (in medical terms: utilization) at cellular level and regulates crucial processes throughout the entire organism. Under the leadership of company founder and managing director Guido Bierther, Airnergy technology is constantly being developed further.

Millions of Airnergy energy filling stations, so-called vitalizers, are now being used in over 60 countries worldwide: Doctors, therapists, clinics, rehabilitation facilities, sports centers and progressive companies (company health care for employees) rely on this unique technology as part of their health programs. This is because the energy cure has a fundamental effect on the human system - both intracellular and extracellular - and is suitable for therapy, prevention, regulation and regeneration as well as for increasing stamina.

Airnergy is now also extremely popular in the field of anti-ageing and longevity. Beauty, wellness and spa institutes as well as hotels have recognized the benefits of the application and are increasingly offering their customers the unique Airnergy vitalization as an additional service. But private individuals and families are also investing in small energy stations for their homes and using this pioneering method for their health.
There is something for every need. From the power dwarf "Little Atmos" to the premium version "Avant Garde" - there are different versions and variants for different areas of application.

Airnergy is a scientific pioneer and the first technological developer of this unique biotechnology. Since its foundation in 2000, Airnergy International GmbH has had a patent, brand, technology and know-how as well as consistent quality, service, production and company management. As a manufacturing company, it is certified in accordance with DIN EN ISO 13485:2003, the quality management standard DIN EN ISO 9001 and the environmental standard DIN EN ISO 14001.

Airnergy stands for sustainable thinking, action and management. Numerous international awards (e.g. the Fitness Tribune's Century Award for Innovation, the International Prevention Organization IPO Science Award for Innovation, the Five Star Diamond Green Innovation Award from the American Academy of Hospitality Services) speak for themselves.
