Push back. Exercising the neck doesn't mean practicing the muscles of the neck, but stretching the neck to make it look longer. The main point of this action is: lie on the bed or cushion, support your body with your hands and keep it shoulder-width, then bend back gradually until you reach the limit and keep this action for a few minutes. This action can effectively open the shoulders and lengthen the neck, but it should be carried out according to its own flexibility during exercise to avoid excessive bending and injury to the waist and neck.
Chest expansion exercise. Raise your hands, make your arms and shoulders form a 90-degree angle (you can use dumbbells to carry weight) and rotate around your waist and abdomen. To keep your body straight, you can turn right until you reach the limit, stay for a few seconds, then return to the middle position and turn right again. Turn left and right once as a group, and you can do several to dozens of groups a day according to your own situation.
Back push-ups. Sit on the mat or bed, support the ground with your hands and heels, straighten your legs, keep your arms shoulder-width, keep your fingers forward, keep your body in a straight line, bend your elbow slowly, keep your abdomen tense, and then support your body after reaching the limit. This action consumes a lot of energy, but the neck is fully stretched and the shoulders are fully opened during the process.
The arm stretching action. It exists in many broadcast gymnastics. First of all, stand shoulder to shoulder with your feet apart, raise your arms over your head and straighten them, then tilt your hips left and right, and press your waist and abdomen down in the opposite direction to keep your arms straight. You can also swing your hips forward and your waist, abdomen and arms backward.
The above actions plus daily exercise, I believe you can also harvest beautiful butterfly bones.
