Spinal stretching

The spinal muscles form a thick, elongated muscle mass that stretches from the top of the neck to the lower back. This column of long, thin muscles extends along the posterior part of the vertebrae. They connect the vertebrae together and help to straighten, turn and tilt the trunk.

Technical sheet of spinal stretching:

Sitting on a carpet or towel, with your back straight, you bend your legs slightly, feet flat. In this posture, put your hands on your knees, then extend your arms, and let yourself be dragged backwards (as if the weight of your entire bust was forcing you to do so).

Tilt your head forward so that your chin is as close as possible to your sternum. Now round off the back and let the spinal muscles stretch passively. To go a little further in the stretching, transfer the body weight backwards.

To do a good stretch, you will have to respect these rules:

Remember to breathe continuously ( Deep breathing cycle of inhalation and exhalation)
Never block your breathing when stretching.
Do your stretching for at least 30 seconds
Stretching will always be done gradually. So that your muscles can get used to this type of work.
Stretched muscles: 

Main muscle : Spinal muscles

Secondary muscle: Large dorsal; medium trapezius, lower; rhomboids; small round and large round

Role of spinal muscles : 

These muscles are erectors of the spine and therefore responsible for self-growth. As spinal extensors, they straighten the trunk and control the flexion of the spine. Finally, they control the inclination of the column.
