The Serratus Anterior - this muscle is abducts the scapula and is commonly emploed in pushing movements - like punching. As boxers punch alot these muscles are very well developed

The strongest protractor of the scapula is the serratus anterior muscle. It originates from the upper ribs and inserts along the medial border of the scapula. Contraction of the serratus anterior muscle pulls the scapula forward around the rib cage.
The serratus anterior muscle in humans and the serratus ventralis muscle in cats are functionally equivalent but have different names due to anatomical differences and the naming conventions in comparative anatomy. The term "serratus" refers to the serrated or saw-like appearance of the muscle, while "anterior" and "ventralis" indicate their positions in the respective species.
The serratus anterior muscle is primarily innervated by the long thoracic nerve (C5-C7) which arises from the brachial plexus. This nerve provides motor innervation to the serratus anterior muscle, which is important for stabilizing and protracting the scapula during shoulder movements.
serratus anterior
Serratus Anterior, moves scapula forward.
The Serratus Anterior muscle is responsible for holding the scapula against the chest wall. It helps stabilize the scapula and is important for proper shoulder movement and function.
Abducts scapula (moves scapula away from spinal column)
