If people with thick necks want to lose body fat by plastic surgery, I don't recommend it, because the blood vessels in the neck are very important to people's lives. Here I recommend two tests and how to solve the problem of thick neck, so that you don't have to worry about image damage. 1, the lower pressure head (neck flexion and extension) naturally stands shoulder width, chest out, and hands cross to support the head. Press the head forward with both hands, and at the same time exert a reaction force on the neck, press it to the chest, and stop. Then slowly raise your head back and press your hands down at the same time, exerting a reaction force until the back head leans back. Then slowly restore the head to the left, and at the same time apply a reaction force to the right with the right hand until the back head leans back. 2. Press your head sideways (neck flexion and extension), stand with your legs shoulder width naturally, hold your chest out, and hook your right hand from the top of your head to the upper part of your left ear. Press your head down to the right with your right hand, and at the same time, the neck exerts a reaction force to the left, pressing it to the upper part of your right shoulder, and pausing for a moment. Then slowly restore the head to the left, and at the same time apply a reaction force to the right with the right hand until the head leans slightly to the left. Do it alternately. In fact, the two methods you mentioned can be carried out at any time, which is a very convenient method. What should I do if I really want to solve the problem of thick neck? Give it a try. Maybe it will really help you.
