Anatomical illustration of pectoralis major muscles. If you are not clear, please come and take a look

The pectoralis major muscle is located in the shallow layer of the anterior upper thoracic area. Of course, there are many functions of the pectoralis major muscle, and in the training method, there are many methods to train the pectoralis major muscle. So, what is the anatomical diagram of the pectoralis major muscle? If you are not clear, please take a look. Let’s take a look!

　　　Anatomical diagram of the pectoralis major muscle (42 muscle anatomy, take you to learn about the knowledge of pectoralis major muscle.)

　　Pectoralis major muscle (pectoralis) Major) is superficial in the anterior and upper upper part of the thoracic area.

　　Starting end: i.e. clavicle (medial half of clavicle), thoracic ribs (sternum and superior 5-6 cartilage) and abdomen (anterior wall of rectus abdomen sheath).

　　Stop point: humeral grand tuberous ridge (crossing the clavicle and abdominal muscle bundles upwards).

　　The muscle abdomen is fan-shaped, with a "U"-shaped flat tendon ending at the ridge of the ridge of the ridge of the trunk (lateral lip of the internode groove).

　　1. Slope dumbbells

　　　Sister a pair of dumbbells with both hands and lie on the adjusted downward dumbbell bench. The head and back are close to the bench, the head should be lower than the upper body, and the back should be kept straight. Fix your feet or legs with the stud legs at one end of the bench. Hold the bell on the outer side of the lower part of the pectoralis major muscle, bend the elbows, and the dumbbell head should be opposite. Focus on the pectoralis major muscle to keep the pectoralis major muscle exerting strength. Push the dumbbells up for a short stay, and perform peak contractions, and then slowly place the dumbbells on both sides of the bottom ribs under the dumbbells, and the falling time will exceed 1 second to 2 seconds. Go to the position relative to the downward breast nipples. Fully stretch the chest muscles and keep the chest tense.

2. Sitting position, push the chest

　　First adjust the seat of the instrument to a suitable height. The standard is that the height of the grip is the same as the height of the upper edge of the chest, and then adjust the weight. After sitting on the seat, the head, upper back and hips are pressed against the backrest at the back, and the waist is tightened forward. After preparing the position, straighten the chest, tighten the abdomen, look straight, hold the handle with both hands, then inhale deeply, feel the chest exerting force, push the weight up, and exhale at the same time, push to the top When the elbow joint is not fully extended, then pause for 1 second, restore, inhale at the same time, and exert force again when the two arms are in a straight line, and practice repeatedly.
