Front deltoid

Front of the shoulder · Common

What this muscle is

The front part of the deltoid, from the outer third of the collarbone to the humerus. It lifts the arm forward and up and rotates it inward.

Why it gets uncomfortable

Too much pressing; rounded shoulders that keep the front fibers shortened; work that holds the arms forward for a long time.

How it usually feels

A sore, full feeling at the front of the shoulder; a pull across the front of the shoulder when the arm opens out; after training, the front of the shoulder is the sorest spot.

What helps

Rear-deltoid stretch: draw one arm across toward the other side. Do more rear-deltoid and pulling work. Ease rounded shoulders and a forward head.
