1. What muscle is the middle seam of the pectoral muscle?
The middle seam of pectoral muscle is actually what we often call the pectoral muscle groove, which is located in the middle of the chest. It's actually a sternum in the middle of pectoralis major. As we all know, bones are molded and cannot be molded. The best way we use in sports is to enlarge the pectoral muscles on both sides, giving people a visual effect. Through the middle seam of pectoralis major, the thickness and circumference of the whole pectoralis major can be displayed.
Second, the reason why the middle seam of pectoral muscle is too wide
This reason is largely determined by natural factors. Some people's bones are naturally small, so the outline of the middle seam of pectoralis major is not obvious, and the fiber direction of pectoralis major is mainly transverse, which is determined by the length of pectoralis major fiber.
Secondly, the thickness of pectoralis major is not enough. Generally, the thin pectoralis major will give people a feeling of weakness, not to mention the prominent middle seam of pectoralis major. Therefore, the thickness of pectoralis major is generally not enough for people who have just participated in fitness, resulting in the gap between pectoralis major is either too large or too wide.
Third, how to improve the short board with too wide chest muscle seam?
1, narrow dumbbell bench press
At the beginning, the body lies on a flat bench, holding the dumbbell on the chest with both hands, palms inward, arms straight, shoulder blades contracting backwards and sinking to keep the body stable. The dumbbell descends slowly during exercise, which makes the chest muscles have a strong sense of stretching. When the dumbbell is away from the chest 1 cm, the peak contraction 1 sec makes the tension of the pectoral muscle reach the maximum, and then the pectoral muscle contracts rapidly inward.
2, barbell chest push
First, choose the weight of the barbell piece, stand on the ground, keep your feet at an appropriate distance, keep your spine in a neutral position, bend your elbow with your arm and press the barbell piece with your hand, and put it in the upper chest position. When exercising, contract the pectoral muscles, let your hands push the barbell piece forward and stay for a few seconds to maximize the contraction of the pectoral muscles. Then, control the recovery speed of the barbell piece and repeat the exercise again, which will make the lines inside the chest muscle more obvious.
3. Smith table press with V-handle
Put a flat bench under the Smith frame, so that the bench and barbell are in the same plane and in the middle position. You can also describe the position of barbells with parallel flat benches. Your body is lying on a flat bench, your legs are bent and your knees are put on the ground to support your stability. The trainer will clamp the V-shaped handle in the center of the barbell, so that your scapula will contract and sink slightly during exercise, ensure the stability of your scapula, control the moving speed of the barbell, and make your chest muscles. It should be noted that when pushing the barbell up, it is necessary to increase the speed, let the arm push the barbell up close to the trunk, and squeeze the chest muscles with both arms.
Summary: The training intensity of each movement should be determined by oneself, but it should be combined with one's own endurance, according to one's ability and long-term training. Soon the middle seam of the pectoral muscle will be narrowed, and the shaping effect of the pectoral muscle will be obvious. Bian Xiao suggested that friends can take it as an episode of pectoralis major exercise during training, and then strengthen the exercise after the pectoralis major exercise. Of course, if you practice the middle seam of your chest muscles effectively, this exercise method should still be implemented.
