The muscles that are involved in the circumduction of the shoulder joint are the pectoralis major, deltoid, supraspinatus, long head of triceps, biceps brachii, subscapularis, infraspinatus, coracobrachialis, teres major and minor and the latissimus dorsi.
Rectus abdominis is the prime agonist and the superior and inferior oblique muscles are synergists. Erector spinae is an antagonist including a number of other muscles of the back.
As you lift the soup can, you are contracting your biceps (the agonist) and relaxing your triceps (the antagonist). As you lower your arm, you are contracting your triceps (the agonist) and relaxing your biceps (the antagonist).
boxing give incredible shoulder muscles and so do pullups
Circumduction and rotation ARE possible around the hip joint.

the deltiod muscle
frontal plane
weakness or tightness of the iliopsoas (psoas major/iliacus)
the antagonist of adduction is the pectoralis major
Ball and socket joint allows the above movements. Shoulder and hip joints are classic examples of this type of joints. Shoulder joint is much more mobile and circumduction movement is well marked in that joint.

Rotation involves, Rotation of the head, neck and lower limb and circumduction, abduction is the angular movements: abduction, adduction and circumduction of the upper limb at the shoulder
The shoulder joint is a ball and socket joint, which is the type that allows the greatest range of movement. it allows the arm to move forward and backward (as when you swing your arms while walking); abduction and adduction (as in jumping jacks); and many intermediate movements.
The antagonist to the gastroc and soleus muscles is a combination of muscles, primarily the tibialis anterior and fibularis (peroneus) tertius.

deltoids are the back shoulder muscles and trapezoids are the muscles around the shoulder/neck/back area
