The biceps or biceps brachii (Latin: musculus biceps brachii, "two-headed muscle of the arm"). Its main function is at the elbow where it flexes the forearm and supinates the forearm. It is the main forearm supinator. #biceps #bicepsbrachii #musculobiceps #bicepsmuscle #bicepsexcercise #bicepsgym #shoulderanatomy #anatomiadehombro #braquial #brazo #musculosbrazo (en Unidad De Especialistas Santafe Real) https://www.instagram.com/p/CbJkfWmtINK/?utm_medium=tumblr

Episode 28: “Forearm Position and its Effects on Elbow Flexor Activity" The biceps brachii not only flexes the elbow, but also supinates the forearm (aka the radioulnar joint). Thus, when performing a biceps curl with the forearm supinated, you can maximize biceps brachii activation. The brachioradialis not only flexes the elbow, but also serves to pronate AND supinate the forearm (based on initial radioulnar joint position). EMG studies reveal that the brachioradialis demonstrates higher levels of activity when the forearm is in either a neutral or pronated position. The brachialis has the largest physiological cross-sectional area of the elbow flexors. Because it inserts into the ulnar tuberosity, it is UNAFFECTED by forearm position and thus is active during all forms of elbow flexion, regardless of forearm position. One of my favorite ways to simultaneously hit all three primary elbow flexors is shown at the end. Citation: Levangie, Pamela K., and Cynthia C. Norkin.

Episode 27: “How to isolate the LONG & SHORT head of your Bicep Brachii!” The Bicep is given it’s name for having two heads, while Brachii comes from the Latin word for arm. While both the long head & short head insert onto the Radial tuberosity. The Long head originates from the Supraglenoid Tubercle of the Scapula, while the Short head originates from the Coracoid process of the scapula. The difference between working these two muscles comes down to the position of your shoulder. When in shoulder flexion, the long head of your bicep is on slack allowing the short head to be focused on. Examples include Preacher & Spider curls. Note: Keep a neutral spine when doing this! Vice versa when the shoulder is in neutral/extension the long head of the bicep becomes more stretched isolated. Examples include Incline Dumbbell curl & Barbell Drag curl. The short head often adds the thickness in the frontal plane, while the long head forms the peak of your bicep. #biceps #arms #gunz #guns #bicepsbrachii #curls ______________________________________________ The Prehab Guys: Optimizing human performance and functional capacity, promoting longevity, and keeping your body in tune one post at a time.
