Muscle strength deficits in the lower trapezius muscles are also a common clinical finding in patients with rounded shoulders as it has been speculated to restrict zygapophyseal extension in the middle to lower thoracic spine. [36] Therefore, RSP treatment often targets the symptoms or root causes associated with these problem areas.
At the scapulothoracic joint, the middle and lower fibers of the trapezius and the rhomboids contract to perform retraction of the scapulae. [5] To a lesser extent, the biceps are involved to flex the elbow joint, [6] while the spine erectors isometrically stabilize the lower back. [7]
An example of trapezius function is an overhead press. When activating together, the upper and lower fibers also assist the middle fibers (along with other muscles such as the rhomboids) with scapular retraction/adduction. The trapezius also assists in abduction of the shoulder above 90 degrees by rotating the glenoid upward.
Stand in the middle of the trap bar/hex bar with your feet shoulder-distance apart. 2. Hinge at your hips and lower down, with a slight bend in your knees, until you're far enough down to grab the ...
Strengthening, especially of (1) the middle and lower back support muscles and scapula retractors, and (2) the longus colli and the deep neck flexor muscles. [35] Stretching muscles that cause neck protrusion, especially of the upper fibres of the trapezius muscle. [36] Lower cervical flexors: sternocleidomastoid, anterior and middle scalene ...

The five muscles that comprise the function of the shoulder girdle are the trapezius muscle (upper, middle, and lower), levator scapulae muscle, rhomboid muscles (major and minor), serratus anterior muscle, and pectoralis minor muscle. [3]
A 2017 study found that pronated grip activated the middle trapezius more than the neutral grip, but that overall the muscle activation of different grip variants was similar. [7] Muscle activation is significantly different depending on whether the pull-up is completed individually or in a set without resting between repetitions, which is more ...
