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.
If a weight is used, then it rests upon the shoulders, or is held in the hand(s). This is an isolation exercise for the calves; it particularly emphasises the gastrocnemius muscle, and recruits the soleus muscle.

The lifter stands erect, hands about shoulder width apart, and slowly raises the shoulders as high as possible, and then slowly lowers them, while not bending the elbows, or moving the body at all. [2] The lifter may not have as large a range of motion as in a normal shrug done for active flexibility. It is usually considered good form if the ...
Muscles in the Lateral compartment of leg also weakly participate, namely the Fibularis longus and Fibularis brevis muscles. Those in the lateral compartment only have weak participation in plantar flexion though. The range of motion for plantar flexion is usually indicated in the literature as 30° to 40°, but sometimes also 50°.
The back muscles can usually heal themselves within a couple of weeks, but the pain can be intense and debilitating. Other common sources of back pain include disc problems, such as degenerative disc disease or a lumbar disc herniation , many types of fractures, such as spondylolisthesis or an osteoporotic fracture, or osteoarthritis .
The triangles of the neck describe the divisions created by the major muscles in the region.. The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck ...
