8 grams of protein per kilogram (kg) of body weight ( 4). The current American Dietetic Association recommendation for most individuals is. When you consume a greater amount of protein, you tip the scale to muscle protein synthesis. If you are unsure of how to do this safely, consult a dietitian for guidance. General recommendations to reduce body fat include eating a diet rich in fruits and vegetables, whole grains, and a variety of protein sources. In contrast, there is a typical process that occurs at the same time, called muscle protein breakdown. They are the building blocks of muscle - so, the more you consume (to an extent), the greater the ability to build muscle (called muscle protein synthesis). How should you eat if chest definition is your goal? They are the pectoralis major, pectoralis minor, and serratus anterior. There are three primary muscles comprise the chest. It pulls the shoulder blade around the ribs to prevent scapular winging, providing stability to the shoulder during pushing movements. The serratus anterior has a sawlike origination on the outside front of the first through eighth ribs and ends on the medial border of the shoulder blade (closest to the spine). It also assists with shoulder stability and respiration. The pectoralis minor’s job is to stabilize the shoulder blade by pulling it forward and down against the rib cage - an action known as protraction of the shoulder blade. It’s also involved in movements such as horizontal adduction (as if you were bear-hugging someone) and internal rotation of the humerus. The sternocostal head, on the other hand, brings the arm down from a forward or flexed position. It also adducts the humerus - which means it brings the arm inward toward the body’s midline - and assists in internal rotation of the same bone. The clavicular head flexes the humerus, or upper arm bone, by raising your arm in front of you. These are antagonistic to each other, which means that as one contracts, the other relaxes. The pectoralis major is a unique muscle because it has two heads - the clavicular head and the sternocostal head. It is a smaller accessory muscle primarily involved in respiration (breathing) ( 2).
