Wrap plastic wrap around your shoulders and exercise every day to make you sweat there. It takes a long time to have an effect.

I'm sorry it's hard to lose weight in a short time, but it will work over time.

I suggest practicing yoga to help stretch. If there are no conditions. Pick a chair at random, put your hands on the back of the chair, press the weight of your whole body on your hands, with one arm bent and two arms straight, and do it 10 twice a day. This will not become very muscular, but also thin, and common sense to do some relaxation, will not let fat accumulate, drinking white water will also help detoxification.

I wish you a good figure!
