The “rotator cuff” is a group of muscles who stabilize the shoulder. It is composed of the Infraspinatus and Teres Minor who externally rotate the humerus (bone of the upper arm), the Supraspinatus, who abducts the humerus up to 15º (after that the deltoids take over), and the Subscapularis who internally rotates the humerus.

Most people’s standard posture is internal rotation of the humerus (contraction of supraspinatus) plus contraction of the upper trapezius.

To create a strong and sweet tango embrace, we need to contract instead the Infraspinatus and Teres Minor, along with the Triceps.


Shoulder External Rotators: Infraspinatus and Teres Minor

Infraspinatus and Teres Minor (Shoulder External Rotators)

Anatomical Function: Infraspinatus and teres minor are part of the Rotator Cuff muscle group. These two externally rotate the humerus.
Tango Function: Ensures that embrace is accurately conveying the direction and force created by lower body.



Anatomical Function: The triceps extend and stabilize the elbow joint.
Tango Function: Maintains tautness in the embrace.
