Methods: First, stand with your feet apart, shoulder width apart, raise your hands and palms together, reach the highest place as far as possible, then take a deep breath, exhale from your abdomen, and the abdomen will naturally gather, and then twist your waist clockwise for 30 times. Pay attention to the abdomen (this is the key to the effect) and turn as round as possible, with a larger range. You can take your time at first and twist your waist counterclockwise.
Turn two or three groups at a time, just two or three times a day, and I can loosen my belt after two days!
I don't know if you are a boy or a girl. If it is a girl, it is best to be within 10 days after the end of menstrual period. You must not lose weight (dieting or doing abdominal exercises) because it will cause endocrine disorders.
Come on! Wish you a slim waist and success.
I heard that it's very useful to control the bike remotely from the bed. I tried, but I didn't stick to it and didn't succeed.
