Exorotation supine 90-degree dumbell
Supine exorotation with the shoulder in 90-degree abduction is an exercise in which you rotate the forearm backwards while lying on your back with a dumbbell. Here, the upper arm remains at shoulder height, while the movement takes place in the shoulder joint.
The exercise specifically targets the rotator cuff, especially the infraspinatus and teres minor. Due to the supine position, the movement is better controlled and compensation from the body is reduced. This makes the exercise very suitable for targeted shoulder rehabilitation.

When this exercise?
Exorotation in supine position with the shoulder in 90-degree abduction is used to strengthen the rotator cuff and improve shoulder stability. The exercise is often used within shoulder rehabilitation, especially when controlled rotational movements are again possible.
In addition, this exercise can be used preventively in athletes who perform a lot of overhand movements, such as in throwing or racket sports. By using light weights and controlled execution, the load can be adjusted well. Application, loading and progression should always take place in consultation with a physiotherapist or other qualified professional to ensure that the exercise is safe and tailored to the individual's load capacity, symptoms and recovery status.
