Are you activating the Biceps Branchii properly?
The biceps brachii, more commonly referred to as just the biceps is a muscle which contains to insertional points which cross over the shoulder joint via the elbow. the long head originates at the supraglenoid tubercle above the socket of the scapula. It lies within the intracapsular space but it still remains extra synovial. The long biceps tendon makes a sharp turn at the humeral head and continues its course in the bicipital groove. arises at the coracoid process of the scapula where it partly blends with the origin tendon of the coracobrachialis. The origin of both attachment points crosses the inside of the elbow and attaches at the radial tuberosity, which is a feature on the radius.
The biceps brachii crosses two joints; the shoulder joints, known as the glenoidhumeral joint (GHJ) which contributes to a number of ranges of motion such as flexion, extension, internal and external rotation, abduction and adduction. The second joint the brachii crosses over is the proximal (towards the inner) radialulna joint. Typically, a hinge joint, has fixed ranges of movement consisting of elbow flexion and forearm supination. In the GHJ, both muscle heads partially enforce opposite movements. The long head pulls the arm away from the trunk (abduction) and turns it inwards (inward rotation). Whereas the short head pulls the arm back towards the trunk (adduction). In the elbow joint the muscle bends the forearm (flexion) and rotates it outwards (supination). The supination is most powerful in a flexed elbow. In addition to the movement functions, the biceps has the important task to support the humeral head within the shoulder joint.
Typically, the muscle can be trained either as a compound or isolation exercise. Isolation exercises are single joint movements in which only one muscle group is trained alone. These exercises are used to “isolate” single muscle groups with minimal involvement from other supporting muscles. Isolation exercises allow you to really focus your attention on a single muscle at a time, leading to better target muscle development .Isolation exercises are often recommended to correct muscle imbalance or weakness that often occurs after an injury. However, the majority of the fitness industry find that training biceps in a compound fashion activates more joints cross the upper region; Chin ups for example, specifically designed for the latissimus dorsi and contributes to greater activation of the biceps.
However, training these in an isolation fashion often activates the short head due to the constant flexion of the elbow. Activation of the long head, however, can be activated with the combination of elbow flexion and partial shoulder flexion.
Therefore, here are some isolation exercises to activate both the short head and long head simultaneously.
