Sitting, lying or sedentary immediately after meals can cause abdominal fat accumulation. But what I want to tell you is that if you lose weight, it's all about your whole body.

Used for thin abdomen, sit-ups, flat support, or relaxing hula hoop at ordinary times. If you want vest line and shaping, it is recommended to download a keep, which has a tutorial.
