Some people's clavicle lines are naturally sexy, and some exercise methods can also make your clavicle lines more concave and convex and have charming lines. Method 1: Open your feet shoulder width, put your left hand behind your head and keep your body upright. Slowly stretch your head to the left with both hands for 8 ~ 10 second, and then repeat the opposite movement for 6 ~ 8 times. Method 2: Lie on the mat, support with your arms, straighten your body as far as possible, and stretch your head upward. Turn your body and head to the right as far as possible, keep your eyes on the heel for 8 to 10 seconds, and then repeat the opposite action for 6 to 8 times. In addition, in order to resist gravity, it is suggested that every woman under the age of 30 should learn to stand upside down for 5 minutes every day to prevent sagging skin and help shape beautiful clavicle lines.
