1, shoulder-shrinking posture mode
It's the first time that there will be a problem of clavicle lifting when doing arm fitness exercise. When the arm is raised, the clavicle will rise, which is caused by too much stimulation on the trapezius muscle. After a long time, the trapezius muscle here will look much bigger;
How to correct this bad posture? We strongly recommend the following training to stimulate the lower trapezius muscle bundle and use the basic principle of mutual inhibition to reduce the stress on the upper trapezius muscle bundle and repair bad posture.
2. The clavicle rotation is limited.
The correct posture of the arm, the clavicle should rotate upward when the arm is extended. If the rotation is limited, the upper end of trapezius muscle may be overcompensated, and the trapezius muscle will become bigger after a long time.
The following training is highly recommended to adjust this bad posture:
Put your back flat on the wall, stick your arms back to the wall with open arms, and then do left and right fitness exercises slowly and controlled to ensure that your back, back of your head and arms don't leave the wall. Do it left and right for 3 groups 15 times.
3, lack of reliability, wing-shaped scapula
As shown in the figure below, if your clavicle leans inward during arm fitness, this situation is also called winged scapula, which is a great embodiment of the reliability of clavicle. If the clavicle is not reliable enough in arm fitness exercise, trapezius muscle is likely to be compensatory, which will also lead to too much trapezius muscle on one side.
Trapezius muscles do not need independent training. Generally, the muscles on the weak side of trapezius muscle will be weaker on the back side, which can improve the training of the weak side of latissimus dorsi muscle. Equipment that can train latissimus dorsi with one hand, such as double-arm drop-down menu and single-arm paddling, can be used to improve the proportion of trapezius muscle after a group of postures are completed.
