The preweal ROTATOR is an innovative rotation training device that was specially developed for the rehabilitation and sports sector. It enables targeted exercises of the shoulder apparatus through rotating movements of the arms and strengthens the upper body, torso and arm muscles.

WHY PREWEAL
Strengthen and mobilize the rotator cuff with targeted flexibility
The ROTATOR from preweal was developed as a shoulder training device to strengthen and mobilize the rotator cuff in all three dimensions. This not only improves your flexibility and agility, but also ensures comprehensive strengthening. Fascia and deep muscles are effectively trained, which leads to holistic body fitness. The individual handling allows the training radius to be adjusted and personal fitness goals to be effectively achieved.
Innovative technology for effective training
The shoulder trainer is characterized by its innovative technology, which enables effective and customized training and, unlike other devices, enables rotating 360-degree movements. The heart of the device is an electronic resistance system that ensures continuous and intuitive training control. This system automatically adapts to the user's individual effort, optimally adapting each training session.

How the shoulder training device works
Individuelle Kraftübertragung
Die Kraftübertragung erfolgt über einen ergonomischen Handgriff, der die rotierenden Bewegungen der Arme ermöglicht. Der Handgriff kann sowohl asynchron als auch synchron verwendet werden, was ein flexibles Handling je nach Trainingsziel erlaubt.
Rotations-bewegungen
Im Gegensatz zu anderen Geräten erlaubt der ROTATOR von preweal geführte rotierende 360 Grad-Bewegungen in alle Dimensionen. Diese Bewegungen imitieren typische sportliche Aktivitäten wie z.B. Boxen, Schwimmen, Tennis, Handball und Basketball. Dadurch werden spezifische Muskelgruppen gezielt trainiert und gestärkt.
Stufenlose Anpassung
Die stufenlose Anpassung des Widerstands ermöglicht eine feine Justierung der Trainingsintensität. Dies ist besonders vorteilhaft für den kontinuierlichen Muskelaufbau, aber auch für die Prävention und Rehabilitation, da das Training langsam gesteigert werden kann, um Verletzungen vorzubeugen und die Heilung zu unterstützen.
Faszien- und Tiefenmuskulatur-Training
Neben der Rotatorenmanschette werden auch die Faszien und die Tiefenmuskulatur durch die rotierenden Bewegungen trainiert. Dies trägt zu einer ganzheitlichen Verbesserung der Körperfitness bei.
Individual power transmission
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 resistance system reacts to the user's effort and automatically adjusts the resistance. This means that the workout always remains challenging and adapts to the user's progress.
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.
An integrated electronic display provides the user with continuous feedback on energy and strength expenditure as well as on the exercise units completed. This helps to monitor training progress and work specifically on different individual goals.
In addition to the rotator cuff, the fascia and the deep muscles are also trained through the rotating movements. This contributes to a holistic improvement in physical fitness.

ABOUT PREWEAL
The founding team of preweal
Tennis, kitesurfing, football - the passion for sport and the personal ambition to improve their own fitness level unites the three preweal founders Christoph, Daniel and Hendrik in a long-standing friendship. As a former goalkeeper and martial artist, Christoph had been looking for a way to specifically strengthen his injury-prone shoulder and at the same time keep it flexible.
As a driving force and creative mind, Christoph started the professional development of the preweal shoulder training device in 2021, which had not previously existed in this specialized form on the fitness equipment market and in physiotherapy practices. Thanks to the passion for innovations in the sports sector and the entrepreneurial spirit of Daniel and Hendrik (from the IT and real estate sectors respectively), preweal is now entering the home stretch as a new type of shoulder training option.
