If it's the first time for a novice to bend his neck and stretch his arm with dumbbells, his posture is not standard enough, his power point is not in place enough, and his neck and waist lend their strength, which will easily cause damage to the cervical spine and spinal column, but if he is a fitness expert, he will definitely not hurt the spine and cervical spine. After all, the real fitness master already knows the correct strength and position of the movement, and will also pay attention to self-protection during the exercise to avoid physical injury caused by strenuous exercise as much as possible.
If you are a newcomer, I want to remind you that you must not use the maximum weight you can bear at the beginning, but use a smaller weight first. First of all, the most important thing is to find the right posture and force point and feel the strength of humerus and shoulder. Fitness is a step-by-step process, and you can't rush for success. When we learn the right posture and strength, we can gradually gain weight.
Now I'll talk about some matters needing attention when bending and stretching the back arm of dumbbell neck.
First of all, the head must be fixed and the movements must be slow and gentle. Otherwise, when exerting force, the neck muscles are easy to borrow. Due to the limited endurance of neck muscles, it is very easy to cause cervical sprain.
Secondly, when doing this action, try to keep sitting posture, keep your back close to the seat, and keep the core stable at all times to prevent lumbar injury.
Finally, you must keep your arms locked during exercise and feel the strength of the triceps brachii.
I hope everyone will go further and further on the road of fitness, pay attention to themselves and never get hurt.
