It's no use. There are many ways to lose weight, among which diet control is the core method. In the process of losing weight, we should strictly control our diet, eat less meals every day and eat more fruits to supplement the vitamins we need every day. Push-ups can exercise your chest muscles and arms well and adjust the distance between your palms. The closer you get, the more you practice your arms. 15~20 once, then rest for 30~60 seconds, then continue, and strive for 3~4 groups.
It's a good method to practice pull-ups with wide shoulders, but this movement can't be done without considerable strength and has no effect. It's better to practice others first.
