Video of a woman performing the serratus punch. The serratus punch is an exercise that works scapular protraction using the serratus anterior muscle and to a lesser extent the pectoralis minor. [1] [2] The exercise even performed at maximum voluntary isometric contraction did not increase pain in one study in people with shoulder pain. [3]
The rhomboid major is a skeletal muscle of the back that connects the scapula with the vertebrae of the spinal column. [1] It originates from the spinous processes of the thoracic vertebrae T2–T5 and supraspinous ligament; it inserts onto the lower portion of the medial border of the scapula. [2]
The shoulder press is performed while seated, or standing by lowering a weight held above the head to just above the shoulders, and then raising it again. It can be performed with both arms, or one arm at a time. This is a compound exercise that also involves the trapezius and the triceps.
Additionally, all three parts can lift the ribs when the shoulder girdle is fixed, and thus assist in respiration. [ 1 ] The serratus anterior is occasionally called the "big swing muscle" or "boxer's muscle" [ 5 ] because it is largely responsible for the protraction of the scapula — that is, the pulling of the scapula forward and around the ...
A 1992 study concluded that 73% of workers aged 20 to 50 years have a right rounded shoulder, [3] and 66% of them have a left rounded shoulder. [3] It is commonly believed that digitalisation [ 4 ] combined with the improper use of digital devices have resulted in the prevalence of sedentary lifestyles, which contribute to bad posture.

The Cunningham technique was originally published in 2003 and is an anatomically based method of shoulder reduction that utilizes positioning (analgesic position), voluntary scapular retraction, and bicipital massage. [7] If performed correctly most patients do not require analgesia for the performance of this technique.
Protraction and retraction is an anterior (protraction) or posterior (retraction) movement, [44] such as of the arm at the shoulders, although these terms have been criticised as non-specific. [45] Reciprocal motion is alternating motions in opposing directions. [46] Reposition is restoring an object to its natural condition. [47]
