For instance, the trapezius, a prototypical convergent muscle, can aid in both shoulder elevation and depression.
Pull-ups also work on the trapezius along the spine and shoulder, and the levator scalpulae along the side of the neck.
It is named after the (upper fibres of the) trapezius muscles, the muscle it was designed to train, with shoulder shrugs.
Usually the sternocleidomastoid muscle or the trapezius muscle is involved.
At its occipital origin, the trapezius is connected to the bone by a thin fibrous lamina, firmly adherent to the skin.
It primarily works the muscles of the upper backthe trapezius and latissimus dorsias well as the biceps as a secondary muscle group.
This is a compound exercise that involves the trapezius, the deltoids and the biceps.
It is deep to the trapezius, and is located directly inferior to the rhomboid minor.
