The arm is mainly divided into upper arm and forearm, in which the upper arm muscle group is mainly composed of triceps brachii, biceps brachii and triceps brachii.
The triceps brachii is located behind the upper arm, with one end connected to the scapula and the other two ends connected to the humerus, which is mainly responsible for straightening the arm. Therefore, the main exercise method is arm flexion and extension, and any exercise that requires arm extension will be used, such as narrow push-ups, narrow grip bench presses, arm flexion and extension, etc.
The biceps brachii is in front of the upper arm, and its two ends are connected with the shoulder joint and elbow joint respectively, which is mainly responsible for the bending of the arm. The main way of exercise is bending, and any exercise that requires the arm to bend hard will use bending.
Extended data:
One thing to be reminded is that you can't just exercise the muscles in your arms to increase your strength, and don't exercise the muscles in other parts of your body. Facts have proved that this is not desirable. Because our body is a whole, only when the muscles of the whole body are developed can we better promote the muscle growth of a certain part of the body. Therefore, in how to exercise arm strength and increase arm strength, it is necessary to give more stimulation to arm muscles and improve the coordinated exercise between other parts of the body and muscle groups. I believe that through the "low frequency" and "medium frequency" exercise of arm muscles, the strength of the arm will be greatly improved.
