Hello, I'll teach you a few ways to thin your arms: the first move to thin your arms: 1. Hold a dumbbell, a bottle filled with water (or sand) or simply use two bricks, straighten from front to top and then back, remember to do this next to your ear. 2. Put it down slowly and repeat this action 20 times. When you finish, your upper arm will feel sour. That's right. Do three groups every day, 20 times in each group. The second secret recipe of thin arm: the right arm is extended high, the left scapula is bent back, the left hand is pressed against the right arm joint, and the left scapula is touched for 5 seconds, then the left scapula is extended high and the side is changed. Do two groups every day, each group 15 times. This is a stretching action, so we should pay attention to what we can do to prevent strain. The third measure of thin arms: 1. Stand with your hands straight forward and your feet shoulder width apart. 2. Draw a circle with both hands and draw a circle outward for 20 times. 3. Draw a circle inward 20 times. Three groups a day. Note: You don't need to draw a big circle. Use the strength of your arms, not your palms. The fourth recipe for thin arms: 1. Stand up straight, spread your feet about shoulder width, spread your arms to both sides, and slowly turn forward. The point is to tighten the muscles on the upper arm. 2. Stand up straight, spread your feet about shoulder width, spread your arms to both sides, and turn around slowly. This is mainly to tighten the muscles of the arms and chest. Note: don't draw the circle too big, so as not to hurt the joints of the shoulders. The fifth measure of thin arm: stretch the right arm forward, hold the upper part of the elbow joint of the right arm with the palm of your left hand, and slowly stretch it to the left and back. When you can't pull it back, stop for ten seconds, slowly let go and change to the other hand. This action is beneficial to the relaxation and plasticity of the arm after exercise.
