The normal weight of male adults is usually calculated by broca's improved formula and Hirata's formula. Specifically, broca's improved formula: ideal weight (kg)= height (cm)-105; Hirata formula: ideal weight (kg)=[ height (cm)- 100]×0.9. According to the calculation, the ideal weight obtained by the two formulas is 63kg and 6 1.2kg, respectively, with little difference, so Broca's improved formula is often adopted in China. The actual weight range is 10% of the standard weight range, which is the normal weight range.
When calculating the standard weight with the height and weight formula, the distribution of fat, muscle content and muscle fat is not considered. The evaluation of health is one-sided, which does not represent the complete health of the body within the standard weight range. Other indicators should be considered comprehensively.

Keeping in shape and weight is actually controlling body fat. Professional athletes should control the body fat rate and maintain a state of the body. We ordinary people don't have to be so demanding, and we can see a lot of fat on our bodies. You can practice in a targeted way.
If you have a lot of abdominal fat, I suggest you do flat support, sit-ups and so on. You can start simple, you can do 50 sit-ups as a group, rest for a few minutes, do the next group, and do several groups a day. Then you can do what you can for the more demanding flat support. After all, this is more intense, and it tends to exercise abdominal muscles rather than lose fat.
