Height and weight are not the only factors to evaluate physical condition. Physical appearance is also influenced by many other factors, such as bone structure, muscle mass, fat distribution and health status.

Even if your weight is within the ideal range, if you have few muscles and a lot of fat, you may still look thin. At the same time, if your bone structure is thin, even if you have the right amount of muscle and fat, you may look thin.

Therefore, if you want to change the appearance of your body, you can consider increasing muscle and reducing fat to achieve this goal. You can increase muscle mass through exercise and fitness, and control fat intake through a healthy diet plan. At the same time, consulting a professional doctor or dietitian can help you make a fitness plan that suits your physical condition.
