M1-D17: Focus SHOULDERS with Core

"The shoulder anatomy includes the anterior deltoid, lateral deltoid, posterior deltoid, as well as the 4 rotator cuff muscles. Each deltoid muscle has three “heads,” or distinct parts: the anterior, lateral and posterior deltoid heads."

"The anterior deltoid is located on the front of your shoulder. It is the part of the shoulder that borders the chest muscles. Its main function is shoulder flexion, which is characterized by raising your upper arms up to the front and overhead. The lateral deltoid is located on the outside of your shoulder. This is the deltoid head that, if highly developed, gives the effect of having very broad shoulders, as well as the “capped” shoulder look."

"The posterior deltoid is located on the back of your shoulder. Its main function is shoulder extension, which is characterized by pulling your upper arms backward and bringing your shoulder blades together. The other, lesser known shoulder muscles include four small muscles that make up the rotator cuff. These muscles aren’t as visible as the deltoids, but they are equally (if not more) important." By - Alex Kingofthegym.com
