SHOULDER AND BICEP WORKOUT AT MUSCLE BEACH
MUSIC: DJ QUADS
The weather was dope so I made my way down to MUSCLE BEACH to crush a shoulder and bicep workout. My boy Oliver also went with me. This was a superset shoulder and bicep workout but I will upload something like this in the future. Enjoy the video and hit the thumbs up
The biceps is a muscle in the upper arm with two heads, called the short head and the long head, which converge into a single mass. It is one of the three muscles in the anterior compartment of the arm, the others being the brachialis muscle and the coracobrachialis muscle, with which the biceps shares a nerve supply. Both heads of the biceps arise from the scapula in the shoulder, and the muscle attaches to the radius (bone), in the forearm. Specifically, the short head of the biceps originates from the coracoid process at the top of the scapula. The long head originates from the supraglenoid tubercle just above the shoulder joint. From here, the long head has a tendon that passes up along the intertubercular groove of the humerus into the joint capsule of the shoulder joint. The tendon of the short head runs adjacent to the tendon of the coracobrachialis and likewise attaches to the coracoid process.
Both heads join on the middle of the humerus, to form a single muscle mass usually near the insertion of the deltoid, to form a common muscle belly. Distally, biceps ends in two tendons: the stronger attaches to the radial tuberosity on the radius, while the other, the bicipital aponeurosis, radiates into the ulnar part of the antebrachial fascia.
The tendon that attaches to the radial tuberosity is partially or completely surrounded by a bursa; the bicipitoradial bursa, which ensures frictionless motion between the biceps tendon and the proximal radius during pronation and supination of the forearm.
Two muscles lie underneath the biceps brachii. These are the coracobrachialis muscle, which like the biceps attaches to the coracoid process of the scapula, and the brachialis muscle which connects to the ulna and along the mid-shaft of the humerus. Besides those, the brachioradialis muscle is adjacent to the biceps and also inserts on the radius bone, though more distally.
The muscles of the shoulder either connect the scapula and clavicle to the trunk, or connect the clavicle, scapula and body wall to the proximal (top) end of the humerus. The trapezius, levator scapulae, and rhomboids originate from the base of the skull and/or spine and connect the scapula and clavicle to the trunk of the body. The pectoralis major, pectoralis minor, latissimus dorsi, teres major and deltoid connect to the proximal end of the humerus and anchor it to the body.
The most important shoulder muscles are the four rotator cuff muscles – the subscapularis, supraspinatus, infraspinatus and teres minor muscles – which connect the scapula to the humerus and provide support for the glenohumeral joint.
Muscles of the arm that enter into the shoulder complex are separated into anterior (flexor) and posterior (extensor) compartments.
