Three simple thin arm tips, as long as you persist for more than two weeks, you can lose the fat on your arm and exercise a little strong arm muscles. Tip of the first thin arm: 1. Hold a dumbbell or a bottle filled with water (or sand) and straighten it from front to back. Remember to do this next to your ear. 2. Put it down slowly and repeat this action fifteen times. When you finish, your upper arm will feel sour. That's right. Do it forty-five times a day, separately. The second secret recipe of thin arm: the right arm is extended high, the left scapula bends backward, the left hand presses the joint of the right arm, touches the left scapula, then extends high, and changes sides. This action is done 20 times a day. If you feel sore from the beginning, it means you have moved to that part. 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. 4. Don't draw too big a circle, use the strength of your arm, not your palm. Exercise arm strength: Tools: 500ml mineral water bottle, filled with cold water (make sure that the two bottles contain the same amount). Action 1: raise your arms horizontally for one second and put them down, and do 20 actions. 2: raise your arms horizontally for one second and put them down, and do 20 actions alternately. 1+ Action 2 is a group, and it lasts for 5 groups every day. Results: Within two weeks, the thickest part of the arm was reduced by 2cm. It was really hard to insist at first, and it turned sour after a few times. But after persistence, you will find that the meat on your arm is disappearing bit by bit.
