The premise is to use your own methods correctly, but insist on tightening your abdomen all the time, but you can't fill your chest with air. Try to exhale until your body becomes the thinnest, and then breathe slightly and shallowly through your chest.

Abdominal contraction exercises the abdominal muscles, so it can not only reduce the stomach, but also reduce fat more easily. Abdominal tummy reduction greatly improves the weight loss effect of walking. Abdominal reduction can be done on many occasions, such as using a computer, taking the subway and so on. If combined with walking, you can improve the weight loss effect by 40%.
