Related Shoulder Muscles

The deltoid is the rounded shoulder cap muscle with anterior, middle, and posterior fibers covering the shoulder joint. It abducts, flexes, and extends the arm for raises and presses. Builds the V-taper and protects the rotator cuff.

infraspinatus muscle

Infraspinatus caps the back of the shoulder blade, externally rotating the arm for throwing and serving. Key rotator cuff muscle for shoulder stability in presses and pulls.

The subscapularis is the anterior rotator cuff muscle filling the scapula's subscapular fossa. It internally rotates the arm and stabilizes the shoulder joint. Crucial for fitness in presses, pulls, and preventing dislocations.

The supraspinatus tops the rotator cuff on scapula's fossa, initiating shoulder abduction. Vital for overhead presses and impingement prevention in weight training.

The teres major is a thick muscle from lower scapula to humerus, adducting and internally rotating the arm. 'Lat's little helper' for pulling exercises like rows and pull-ups.
