Anatomical illustration of lats dorsi muscles let you understand lats dorsi muscles

Lataxis dorsi is located on the lumbar back and the posterior and lateral sides of the chest. Of course, the lataxis dorsi also has many functions, such as proximal fixation, which causes the shoulder joint to extend, adduction and internal rotation. So, what is the anatomical illustration of Lataxis dorsi? Let’s take a look!

　　　Anatomical illustration of Lataxis dorsi (42 muscle anatomical explanations, take you to learn about Lataxis dorsi)

　　Site: on the lumbar back and the posterior and lateral sides of the chest.

　　Starting point: The aponeus starts from the seventh to twelfth thoracic vertebra and all spinous processes of the lumbar vertebra, the central sacral crest, the posterior part of the iliac crest and the tenth to twelfth ribs.

　　Stop point: Humerus Small nodule ridge.

　　Inner nerves: thoracic and dorsal nerves originating from the spinal brachial plexus.

　　　Latissimus dorsi training method

　　1. Latissimus dorsi pull down

　　(1) Hold the handles at both ends of the upper horizontal bar with both hands facing outward, the spacing between the hands is wider than shoulder-sided, and the thumb is upward.

　　(2) Sit down the lower body with your feet steadily on the ground, and the upper body is slightly leaning backward to form an arch shape.

　　(3) Inhale, pull the crossbar vertically from the upper position to the position of the chest and sternum

　　(4) Stop for 2-3 seconds, and use force on both arms to avoid fierce force Pull or uncontrolled restore

　　(5) Exhale, slowly restore along the original path, repeat, pay attention to not swaying greatly from the upper body, and move vertically up and down.

　　2. Pull-up

　　(1) Hold the horizontal bar inward with both hands shoulder-width, bend the knees slightly when hanging, and look straight ahead and above.

　(2) Pull up the body smoothly until the jaw is as high as the bar.

　　(3) Then slowly lower the body to the beginning and complete the entire movement when the arm is straightened.

　　3. Bend over and row the bar

　　(1) Width distance Standing, hold your hands straight, the grip is slightly wider than the shoulder, and your arms are completely straightened; bend your knees slightly, bend your back from your hips, keeping your body at a 45-degree angle; hold the bell in front of you, slightly lower than your knees.

　　(2) Tighten your shoulder blades, tighten your entire upper body, and lift the barbell to your upper abdomen.

　(3) Pause for a moment, then slowly get off the bell and return to the starting position; repeat the above movements until you complete a set of training.

　　Tip: When exercising, you need to exercise all parts of your body, so in addition to latsimus dorsi, you need to understand the muscles of all parts of your body. 42 muscle anatomy will take you to understand the knowledge of all muscles of your body 》
