The Embrace makes a number of different actions and adjustments.

The pale blue muscles are the embrace stabilizers, always in a gentle contraction for both partners: the shoulder external rotators (infraspinatus and teres minor) ensure that the hands are moving in sync with arc’s muscle chain.  Triceps contraction keeps the embrace taut.

The violet muscle is the supraspinatus. Marks contract this muscle to adduct one arm along with obliques contraction to show direction lateral to the Mark.

The blue muscle is the deltoid. It contracts to stabilize the embrace when using psoas contraction to show direction toward or away from the Mark.

We release the deltoid to flex the shoulders when opening the embrace and to extend the shoulders when closing the embrace. We then contract it again to stabilize the new position.

In volcadas: The Mark’s triceps contracts further to flex the elbows just enough to give permission to the Revel to lean toward the Mark. Then both partners contract strongly all the external rotators, deltoids, and triceps to stabilize the shoulder and elbow flexion. (Increased hip flexion increases the degree of lean.)

In colgadas: The Mark’s triceps relax to extend the elbows just enough to give permission to the Revel to hang away from the Mark. Then both partners contract strongly all the external rotators, deltoids, and triceps to stabilize the shoulder and elbow flexion. (Increased hip flexion increases the degree of hang.)

Exercises

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.

Triceps

Triceps

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

Supraspinatus

Supraspinatus

Anatomical Function: Supraspinatus abducts the arm.

Tango Function: Stabilizes the embrace when the intention is lateral to the Mark.
Supraspinatus exercise: Instead of pushing with your hand against the wall (this works the external rotators), push with the part of your lower arm just below the elbow.

Deltoid

Deltoid

Anatomical Function: The Deltoidsflex the shoulder.

Tango Function: Stabilizes the embrace when the intention is toward or away from the Mark.
Just do the first exercise here.
