The first thin arm method:

1. Hold a dumbbell or a mineral water bottle filled with water (or sand) and straighten it back from front to top. 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 method of thin arms:

Lift the right arm, bend the left scapula to the back, press the joint of the right arm with the left hand, touch the left scapula, then lift the right arm and change sides from left to right. Do this 20 times a day.

If you feel sore from the beginning, it means you have moved to that part.

The third way to thin your 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.
