Therapy meets Training
Strong Shoulders. Endless Mobility.
The ROTATOR is a professional rotational training system designed for modern training and therapy concepts. Guided, three-dimensional movements with resistance promote natural strength development of the shoulder complex, upper body, and arm musculature through integrated kinetic chain training.
The shoulder is the most mobile — and at the same time the most injury-prone — joint in the human body. Sustainable function is not developed through isolated exercises, but through controlled, multi-dimensional movement.
That is exactly why we developed the ROTATOR: a guided training system with 360° rotation and constant bidirectional resistance. It functionally integrates the rotator cuff into the entire kinetic chain of shoulder, core, and arm.
30+ exercises. One device. Minimal space requirements. Resistance, radius, and inclination angle can be adjusted individually — for every performance level, from late-stage rehab to elite sport. Structured, reproducible, and with no ongoing operating costs.
EU-patented. Made in Germany.
The compact training system ROTATOR offers 30+ different exercises for prevention, rehabilitation, and performance-oriented training with minimal space requirements.
In contrast to other devices, the preweal shoulder training device allows rotating 360 degree movements in all directions. These movements imitate typical sports activities such as boxing, swimming, tennis, handball and basketball. This allows specific muscle groups to be specifically trained and strengthened.
The stepless adjustment of the resistance allows for fine adjustment of the training intensity. This is particularly beneficial for rehabilitation, as the training can be increased gradually to prevent injuries and support healing.
The power is transmitted via an ergonomic handle that enables rotating movements of the arms. The handle can be used both asynchronously and synchronously, which allows flexible handling depending on the training goal.
The ROTATOR is designed for ambitious athletes aiming to specifically enhance performance in rotational and overhead sports such as golf, tennis, handball, basketball, swimming, rowing, boxing, and gymnastics.
In addition, the system provides a structured solution for preventive upper body training as well as for rehabilitation following injuries or surgical procedures. Its guided, controlled movement makes the ROTATOR equally suitable for use in therapeutic settings.
The system also enables wheelchair users to perform functional, multi-dimensional upper body training with individually adjustable resistance.
With the ROTATOR, preweal provides a comprehensive solution for modern therapy and training concepts. The system combines mobilization and stabilization through controlled, three-dimensional movement, supporting the sustainable development of shoulder function – from prevention and rehabilitation to performance training.
Tennis, kitesurfing, yoga, or football – a shared passion for movement and the ambition to develop performance sustainably have connected preweal founders Christoph, Daniel, and Hendrik for many years.
As a former goalkeeper and martial artist, Christoph was searching for a training solution that would not only strengthen the injury-prone shoulder in isolation, but stabilize and mobilize it functionally. Driven by this need, the development of the ROTATOR began in 2021 – a specialized training system designed to systematically connect therapy and training.
Combining entrepreneurial expertise, innovative thinking, and athletic experience, this vision evolved into preweal – and a patented system setting new standards in modern shoulder training.
