In the human body there is a huge number of all kinds of muscle groups, large, medium, and very small. Most human muscles are visible beneath the surface of the skin, but there are also such muscles that are hidden under a layer of other external muscles. Their development is visible from the outside only with a significant increase in the course of the training process.
Let us dwell on those muscle groups that are pronounced and have the greatest value in bodybuilding and bodybuilding. So, the main muscle groups of the human body, the main muscles.
Let’s start with the muscles of the shoulder (deltoids).
The shoulder itself is covered with three bundles of the deltoid muscle, popularly called deltas. The deltoid muscle consists of anterior deltas, mid-deltas (lateral deltas), and posterior deltas. The front delta beam is the smallest, the middle delta beam is most pronounced, and the rear delta beam is a little smaller. The shoulder part is also called that area of the arm, which is directly attached to the shoulder joint and the elbow joint. In this section, the biceps of the shoulder (biceps) and the triceps of the shoulder (triceps) are located. But often these muscles belong to the hands, and therefore we will focus on them further.
In the shoulder girdle, there is also upper and middle trapezius muscle. Trapezius muscle covers most of the back passing along the spine from the neck to the waist. The upper part of the trapezium is located in the cervical region, the middle part of the trapezoid is located along the center of the back of the thoracic region, and the lower part of the trapezius muscle is extended to the lower back.
Next, the chest muscles
The chest is covered with the pectoral muscles: the pectoralis major muscle and the pectoralis major muscle. Thus, conventionally, they can be divided into three parts of the pectoral muscles: the clavicular head of the pectoralis major muscle, the middle (central) head of the pectoralis major muscle, and the lower part of the small pectoral muscle. On the sides, closer to the latissimus muscles in the chest, the dentate muscles of the chest are also located, but they are so small that they often do not increase their size, but only work on the drawing.
The back muscles are located behind the body.
The spinal muscles consist of trapezius muscles, the latissimus muscles (popularly called wings), and the multiple extensor muscles of the spine. In the middle section of the trapezius muscles, there are also rhomboid muscles, large and small round muscles, and other, smaller muscles.
The muscles of the arm make up the biceps of the shoulder, the triceps of the shoulder, the muscles of the forearm (the flexor muscles of the hand, and the extensor muscles of the hand). The biceps consists of the inner head and the outer head, the brachialis muscle brigialis. The triceps consists of the lower bundle, the middle and upper outer bundle of muscles. And as already mentioned, the extensor/flexor muscles of the hand are located on the forearm.
The muscles of the legs and buttocks are located below.
The muscles of the legs are divided into the muscles of the thigh and lower leg muscles, gluteal muscles. On the front of the thigh is the quadriceps, the quadriceps muscle of the thigh. It consists of: the middle broad muscle, the lateral broad muscle, the rectus muscle, the tailor muscle, the rectus hip muscle, the tensile fascia muscle. Behind the thigh is covered with the biceps of the thigh – the hip flexor muscle, the biceps of the thigh. The shin is covered with the gastrocnemius muscle, the soleus muscle, and the anterior tibial muscle. The buttocks consist of the gluteus maximus muscle, the gluteus maximus muscle, and the greater trochanter.
Abdominal and neck muscles
Ab muscles (six-pack)
The abdominal muscles include the rectus abdominis muscle, called the abs, and lateral oblique abdominal muscles – the lateral abs. The rectus abdominis muscles have many connected heads, from which the press is often called a washboard. The muscles of the neck are so numerous that it makes no sense to call the neck muscles. To swing the neck muscles separately, no one is able, and this is not necessary. Two neck exercises involve all the muscles in the neck.
