About this Book


For more than 15 years, I have been working within the scope of by now over 1000 prevention classes with patients who seek professional help dealing with back problems. During my sports studies, I already got to know the complexity and the individual fates connected to it. In the course of my education in becoming one of Germany’s first teachers for back training and later as an instructor for the Forum Gesunder Rücken – besser leben e.V., I also became aware of the discrepancy between modern and seemingly out-of-date ways of therapy approaches for back problems.

Considering exercise as a measurement of all things when it comes to prevention and therapy of back pain, still has not been put into practice. After such a long time, it very well should be permitted to ask what the problem seems to be: even today I am still confronted over and over again with patients whose doctors only know about the therapy order of injection, pills and rest. Exercise is rarely recommended, and often it simply seems to be too late or too expensive to take deconditioning steps against the pain cycle through exercise therapy.

In search of practical assistance for affected persons and of feasible programs to pursue oneself, the FLEXI-BAR came to my attention years ago already, and I have ever since regularly used it in every group. The simplicity of the operation, the complexity in its effect, the positive results in strength, reflex control, and coordination, as well as the applicability in self-training at home combined with short duration of exercise, proved to be a logical concept with a widespread impact on back problems.

For these reasons, I have tried to take a closer look at the whole topic of »training with dynamic bars and vibration« in the current book. However, the more closely I did my research and reinforced the topic, the more I reached the convictions that the topic is perfectly depicted through the FLEXI-BAR and the accompanying concept. Thus, the book came to its title.

Shortly before the printing of this book, a large grocery discount store included a low-priced model of a dynamic bar in their product line – a further indicator for the increasing interest in this concept of training.

Every reader is welcome to try reaching the described effects with any model of a dynamic bar or rather to perform the introduced exercises. Mind you that I do not recommend this, but it would be possible. In my experience, most users will end up with the FLEXI-BAR, which I still use in all classes, from competitive sport over sport for seniors, all the way to therapy.

Have fun with swinging!
