Arms and shoulders, if you want your shoulders to look thinner and sexier, you must exercise your upper arms. Stretch your hands forward with your fingers crossed, keep your shoulders level, keep your thumb down, keep your arms in this position for 2-3 seconds, then reverse your hands and return to the original position. Extend the crossed arms parallel to the shoulders again, then raise them to the front of your face and start to rotate clockwise. After 2-3 times, relax your arms.

This action can make the upper part of the arm get a good exercise. By stretching the arm to make a circle, you can exercise the muscles inside the arm, thus making the muscles strong.

The second measure: shoulders stirred up.

Massage the other shoulder with one hand, while constantly stirring the shoulder, press the arm with your hand, and press the inner muscles of the arm from the shoulder. After this action, the shoulders start to stir up and down quickly for 20 times, and then gently pat the shoulders with your fists to relax.

The third measure: buckle your ears.

Straighten your hands forward, then bend your arms upward with your palms until you touch the earlobe, then put your wrists close to your ears, tilt your elbows inward, and lift your elbows upward, feeling that your arm muscles are stretched. Hold this action for 2-3 seconds, and then relax. This action can exercise the muscles of the arms and shoulders that are not used often, and at the same time can correct the posture. Repeat 5- 10 times.

The fourth measure: hold down the wall.

Stand in front of the wall, hold the wall with your hands and palms at arm's length, and then pull your feet back and open them. The head drives the shoulders to press down, keeping parallel to the back, and the upper body presses down as far as possible until you feel the neck, shoulders and back being stretched vigorously, then relax and do it again for 5 times.
