Biceps exercise: Sliding curl drag curl

Biceps exercise: Sliding curl drag curl

　　Biceps are the favorite part of the gym friends! The main exercise method is a variety of curls!

　Today I will introduce to you a good curl change: Sliding curl drag curl is also called drag curl

How to do it?

As shown in the picture; the shoulders and arms are slightly extended backwards, and then curl the barbell upwards, so that the barbell bar rubs against the torso and slides upwards!

The advantage of this?

The key point of this is to lift the bar along the body. By the ascending process, the long head of the biceps is lengthened on the shoulders, thereby increasing the maximum activity time of the long head.

The biceps have two heads (anatomical picture)

The outer side is the long head (marked green), and the inner side is the short head. In addition to the different lengths, the proximal attachment points are also different, so there are some differences in function.

The proximal tendon of the long head bypasses the humeral head and attaches to the supraglenoid nodules of the scapula (supraglenoid) (supraglenoid) (supraglenoid) (supraglenoid) (in addition to the different lengths of these two heads, the proximal attachment points are also different, so there are some differences in function.

The proximal tendon of the long head bypasses the humer tubercle,

　　The proximal end of the short head is the coracoid process connected to the scapula,

　　The distal ends of both heads are attached to the radial tuberosity and bicipital aponeurosis surrounding the forearm.

　　When performing a sliding curl, because putting the arm behind the body, you can stretch the long head, so that the long head can have more space in the curl (ROM, range of) motion) is in a highly active state.

　　In addition, electromyography (EMG, Electromyography) shows that the long head has a relatively large activity in the early stage of elbow flexion (when hand straightening), and then becomes shorter as the muscle contracts and becomes shorter. The short head has a stronger activity in the later stage (when it is about to bend to the vertex).
