In order to be able to achieve your best performance on a permanent and regular basis, after the sport is before the sport. As we all know, your body needs its rest periods to regenerate after a strenuous session or competition. Through our magnetic field therapy alternative in sports, we can support you with our Kleinsche fields. In competitive sports especially, the pressure to compete in more competitions in less time and to perform at the highest level on a regular basis is increasing. So better preparation and regeneration can make all the difference. That’s why hundreds of experts worldwide deal with regeneration in sport.

Preparation and regeneration

We are now proud to be able to introduce a new technology that has so far only been known in the testing phase to a few top athletes and sports insider circles. We have succeeded in developing a revolutionary and innovative building block for optimised regeneration. Far away from magnetic field therapy, we present our Kleinsche fields. These have an alternating polar effect:

  • against circulatory disorders
  • better concentration and reaction
  • reduced defect rate


But we have also demonstrated new results in terms of faster response time and reduced defect rates (better concentration) in a study. The studies and tests show stunning results and will be published this year.
Find out more and experience the future benchmark that no competitive athlete should do without.

Some feedback about BIORELAX – Kleinsche fields


Baran Er


During the training, as well as in everyday life, I wear the Kleinsche fields wrist straps, which convinced me as an alternative to magnetic field therapy. I broke my hand in 2020 and the BIORELAX® Pad made it easier for me to get back into training.
I have noticeably more power and feel fitter after training than without the Pad. For me? Never again without.


Lisa Unruh


After training or competition, I want to give my body time for rest and regeneration as soon as possible. The Biorelax products help me to give my body what he needs to be able to perform at full capacity again the next day in training or competition. I use the Biorelax mattress topper and I can feel how much better my sleep has become.

Kleinsche fields were not a concept I was aware of until I started wearing them during strength training in June 2021. Subjectively, it allows me to target muscle groups more specifically, objectively, I noticed an appreciable increase in strength, especially in muscle groups that are more difficult to target, which is of course an enormous benefit in bodybuilding. I am delighted to have found this means of optimisation for myself.
