First lie flat on the floor, put your arms on your sides, then bend your knees slightly, and then lift your hips off the ground with the strength of your lower abdomen. At this time, the core is tightening. The core is "lumbar spine, pelvic hip joint", which refers to the area from below the diaphragm to above the pelvic floor muscle, and its shape is similar to a cylindrical "cylinder".
It should be noted that the core muscles include but not equal to the abdominal muscles. The core muscle group is located in the middle of the body, covering the abdomen, back and pelvis. Core muscle group is mainly responsible for stable function, and the coordination between different muscles, muscles and ligaments, and connective tissues is the key to core stability.
When the core strength is insufficient, the spine can not be supported by the core muscles, and it is easy to have bad postures such as neck probing and hunchback, and the body coordination will be poor. The pressure of knee joint and hip joint will increase during exercise, which is easy to cause joint injury and other sports injuries. Based on this, the training of core muscles is very important!
Core muscle group
Core muscle groups refer to the important muscle groups located in the front and back of the abdomen, which surround the body and are responsible for protecting the stability of the spine, such as transverse abdominis, pelvic floor muscles and lower back muscles. The core muscle group is mainly composed of rectus abdominis, oblique abdominis, lumbodorsal muscle and erector spinae.
