Many girls have butterfly sleeve in their arms. These people don't like sports and do heavy work, so the fat on their arms will gradually increase, forming a butterfly sleeve.
Butterfly sleeve is located in the triceps brachii (the rear edge of the upper arm), that is, under the armpit of the inner arm, and there are often two pieces of fat, which we call "butterfly sleeve" figuratively.
Because the muscle area is large and there are few opportunities to use it, even a thin girl with natural beauty often has these two loose pieces of fat, which makes the whole body look bloated and suffers from butterfly sleeve.

Butterfly sleeve's improved method:
Mode 1
Straighten your left arm and lift it to the sky. Hold the left arm with your right hand from the elbow joint and scrape off this part of fat at the root of the left arm one by one. Strength can make your muscles feel a little sore. The action of the right arm is the same as above.
This action can detoxify and promote fat burning, and muscles will consume fat when resisting pressure. Note: the hand that reaches into the sky should be stretched upward vigorously, and the other hand that presses the massage should also use more strength.
Mode 2
Turn your arms around backwards. One is to put your hands on your shoulders and do a small circular motion. The other is to open your arms completely like a wild goose and make a big backward turn. The key point of this action is that when the arm turns the second half circle, it should be as far back as possible, and fully feel the stretching of the back inner side of the big arm (that is, the position where butterfly sleeve is).
Doing this for a long time will make the front of the shoulder very sore. At this time, please change from big circle to small circle or from small circle to big circle. Don't burden other parts of your arm. Concentrate on the trailing edge of the upper arm.
Mode 3
Preparation: Turn your back to the chair or platform below your waist, put your hands back on the platform, take a big step forward with your feet and step firmly on the ground.
Start: Squat vertically, hold hands tightly until the elbow is at a right angle to the knee for 3 seconds, and then return to the ready state for 3 seconds. Repeat 15 round, do three or four rounds every day, and rest for one or two minutes between rounds.
Note: open your shoulders backwards, don't shrug your shoulders, tuck in your abdomen, squat vertically to the ground, and don't lean forward. In order to increase strength, you can extend your feet a little further.
