What are the back muscles?

The back muscles are the largest muscle groups in the body, including the trapezius, latissimus dorsi, sacrospinalis and rhomboids. The trapezius muscle is triangular in shape overall, with trapezoidal shapes on the left and right sides, connecting the shoulder girdle bones with the skull and vertebrae. It is located on the surface of the upper and middle back and forms a bulge. The main artery supplying the trapezius muscle is the transverse cervical artery, and the veins mainly drain to the external jugular vein and subclavian vein through the transverse jugular vein and suprascapular vein. The trapezius muscle plays a role in straightening the head and spine by flexing the head to the same side or rotating the head to both sides. Exercising and developing this muscle can prevent and correct hunchback. The latissimus dorsi is the largest broad muscle in the body. It is shaped like a right triangle and is mainly located under the skin on the back of the waist and chest. The latissimus dorsi muscle is innervated by the thoracodorsal nerve and is a motor nerve. Blood supply is provided by the thoracodorsal artery. By exercising this muscle, transposition transplantation can repair large-area defects such as upper limbs, face, and chest. The sacrospinalis muscle, also known as the erector spinae muscle, is located on the back, with its length from the back of the sacrum to the back of the occipital bone. Its function is to draw the spine to achieve backward tilt. It has obvious segmentation and connects two adjacent vertebrae, which can enhance the flexibility between the spines. The rhomboids are located between the shoulder blades. Actively participating in stretching movements can increase the flexibility of the joints, allowing the scapula to expand and contract to a greater extent. Helps with vertical and horizontal pulling exercises.

Back muscles are the largest muscle groups in our body. Proper exercise training can make the back lines more beautiful and make the back muscles more powerful. Backhand pull-ups and forehand narrow-gap are good training methods for back muscles. This makes the latissimus dorsi participate more during the exercise, and the trapezius and rhomboids play an auxiliary role. It is called low-point training. The sacrospinalis muscles are trained. Some good training exercises can effectively help us strengthen the optimization of back muscles. At home, we can perform W-shaped stretching, 15 in one group, four groups a day. Or perform Y-shaped stretching, 30 exercises per group, two groups per day. When doing sports, you must have a correct posture, otherwise it may easily cause back muscle injuries. Sample strength training methods from small to large weights. When performing barbell training, remember not to bear too much weight.
