How do lazy people exercise and lose their belly?

I'm not afraid you'll lie down and look at your phone, but you'll have to bend your legs and shake them from side to side. The more you shake the body, the better [refuel], the smaller the belly [than the heart], and also relieve low back pain and lumbar muscle strain. When you are fine, you can brush the phone and lie down to shake your legs, the amplitude of the shaking can be, of course, the larger the amplitude of the shaking, the better, and the head can be properly raised. You can try it, without effort, especially for people who don't like to move after meals, it's very comfortable.
