No need to gain weight. Just need to increase physical exercise. If you have a lot of fat on your stomach, exercise. Just turn the fat on your stomach into muscle. You can choose sit-ups. How many more will you make tomorrow? You can also lie flat on the floor. Knees slightly bent. Cross your hands behind your head. Hold your chest out and repeat this process. Just do it a few more times. We should insist on physical exercise. I hope you can have a better figure.

With your current height and weight, your weight is relatively within a reasonable range.

But when judging whether you need to gain weight or muscle, it is also based on your actual physical condition.

If you have a standard weight, but the actual muscle content is less and fat is more, then what you need to do in this case is not to gain weight, but to increase the muscle content of your body.

Standard weight, calculation method, male formula, subtracting 105 from our height is equal to a weight standard you should reach.

So your current height and weight are actually ok, but it should also be judged according to the actual situation and physical fitness.

At the same time, you should also look at your body requirements, whether to maintain the status quo or to become thinner and stronger.

Then judge your specific development direction according to different goals.

I hope I can help you.
