1, swimming can thin the back. If a girl is five big and three thick, she is not very good-looking on the whole. To lose weight quickly and effectively, you can try swimming. Because swimming can strengthen the muscles of the back and reduce the accumulation of fat on the back, swimming can effectively thin the back. Girls who want to lose weight quickly can try breaststroke and butterfly stroke, but they must do warm-up exercises before swimming.

2, doing chest expansion exercises When it comes to doing chest expansion exercises, many people think of doing broadcast gymnastics. I have to say that if a girl wants to slim down her back, she must insist on breast enhancement every day. First of all, open your hands to shoulder level to adjust the rhythm of chest expansion, which can effectively make your body more straight and can also quickly thin your back.
