With ergoHI², we are launching a completely unique product that combines sports science with high-tech. Our know-how from the development of training equipment for pilots combined with decades of experience in the training management of top athletes together result in a complete package that brings about significant improvements, especially in high-performance sports, but also in rehabilitation and popular sports.

Booster for your performance | Booster for your health

The supply of oxygen to the cells in the entire organism is essential for the mental and physical performance of humans. In competitive sports, this has been known for decades, but at the latest since the award of the 2019 Nobel Prize in Medicine for the secret of altitude training, it has also been scientifically proven – hypoxia has a performance-enhancing effect!

But hypoxia not only makes you fit, it also makes you healthy.
Studies prove the positive effect in many different areas:

  • Strengthening and activation of the immune system
  • Improved energy supply
  • Slowing down the aging process
  • Normalization of blood pressure
  • Improvement in respiratory diseases
  • Accelerated weight reduction due to increased fat metabolism
  • Protection of the musculoskeletal system, as there is already a high training effectiveness at low intensities


individual training devices

To train successfully at altitude, you have to know how – and we do! Our sports scientist Christof Weiß has more than 2 decades of experience in altitude training and training control of teams and individual athletes and during this time has made many athletes from different sports to world champions and Olympians with the training concept ergoHI².

Our successful concept ergoHI² combines high intensity training with the altitude training system. Interval training has established itself in professional high-performance sports in recent years. This is supported by numerous current, scientific studies. Of course, regenerative and basic endurance units under altitude conditions are also taken into account in the training planning. Each athlete is analyzed and all areas of their athlete’s life are individually optimized through training, sleep and nutrition counseling to achieve what our concept promises: to increase mental and physical performance through delayed fatigue and thus become more successful and resistant to injury.

ergoHI² ROOM

Training rooms under normobaric hypoxia

By training at simulated altitude, with the same air pressure but reduced oxygen content, the body is trained to significantly improve oxygen uptake in the bloodstream. A more efficient oxygen supply increases the ability to concentrate under high stress and delays muscle fatigue. This increases performance and reduces the risk of injury.

Whether permanently installed high-altitude rooms in buildings or mobile solutions in training rooms, containers or buses, we specialize in individual solutions and are geared to offering versatile solutions due to the different conditions to which athletes are exposed.

Sleeping rooms under normobaric hypoxia

Sleep or prolonged stays at high altitudes increase the formation of new erythrocytes. Red blood cells have a vital function: they absorb oxygen from the air we breathe in our lungs and transport it – bound to the hemoglobin they contain – to every corner of the body. The cells of the body absorb the oxygen and use it for energy production.

Through properly timed altitude sleep cycles, we achieve a significant increase in endurance performance. Our sleep systems are available not only as fixed installations in rooms, but also as mobile variants and on a rental basis. We are the first company in the world to offer our customers high-quality and mobile high-altitude sleeping systems – away from the high-altitude tents that have been on the market until now.

Radergometer ergohi2

ergoHI² BIKE

The ergoHI² BIKE is the absolute top performer among bicycle ergometers. A unique regulation and control technology enables isokinetic and precise HIT training with a load of up to 2500 watts. The training programs are precisely individualized after a performance diagnosis and displayed on the monitors. In this way, the athlete trains exactly in his performance range, where it is most effective and he gets the maximum benefit from his training. 

The bilateral torque recordings provide feedback on even muscle work. Cyclic 360-degree muscle loading trains the front and rear leg muscles in a way that is completely gentle on the joints. Even the most intense workouts do not result in muscle soreness because they do not cause the many small fiber tears that occur from impact loads during conventional intense workouts.

For injured athletes, there are adjustable crank lengths so that the angle of the squat can be determined. If the ergoHI² BIKE is set up in an ergoHI² ROOM, it is possible to start rebuilding just a few days after the injury with a low wattage, but under more difficult conditions due to the oxygen-reduced air.

Whether in rehabilitation or in competitive sports, the ergoHI² BIKE offers the possibility to train the leg muscles in a targeted, effective and thus time-saving way and to raise performance to a completely new level.


The GRINDER is an isokinetic high-end upper body ergometer developed by us and unique in the world. With an applicable forward, backward and sideways movement, the entire upper body including the torso can be trained. With our ergoHI² GRINDER, athletes can train their upper body mainly for strength endurance, but also for explosive strength. Simple endurance workouts and high-intensity intervals can simulate competition-like load patterns through advanced software. 

 The 360-degree cyclic muscle loading is extremely easy on the joints. The performance of the entire upper body can be effectively and precisely trained on a single training device. The susceptibility to injury that often occurs when training with weights is thus avoided. 

 Whether in competitive or amateur sports or in rehabilitation, the programs are individually tailored to the user so that a maximum increase in the overall performance of the upper body is achieved through targeted training in the exact performance range. A lightning-fast, up to 2500 watt strong and precisely reacting brake unit makes the ergoHI² GRINDER what it is: the highest quality upper body ergometer on the market.
