Understanding the BMI Calculator
Your body mass index (BMI) takes your weight and compares it to your height. The BMI calculator is able to tell you if you are overweight, underweight, or at your correct weight for your height. While there is not one specific number that is considered to be your BMI, the numbers are generally close and may range by 5 to 10 pounds. If you fall within this range, then you are at a healthy weight, but if you go below or over, you know that you need to take some steps to improve your BMI.
|Healthy||18.5 to 24.9|
|Overweight||25 to 29.9|
|Grade 1 Obesity||30 to 34.9|
|Grade 2 Obesity||35 to 39.9|
|Grade 3 (Morbid Obesity)||> 40|
Reasons to Use a BMI Calculator
One of the main reasons why people prefer BMI calculators to other weight determining methods is because it is a very simple tool that basically anyone can use. In order to use this tool, all you have to do is get your correct weight and your exact height. You then put both of these numbers into the calculator, and it provides you with a chart, which is also easy to read. By finding your weight and height on the chart, you are able to determine if you are at a healthy weight or not.
Some BMI calculators are now even easier to use, as they will provide you with your weight in numbers, and they don't require you to find any information on a chart. This type of BMI calculator can be found online, as an app on a smartphone, or as a device you can purchase.
Overweight and Underweight
Finding out your BMI allows you to take the steps needed to improve your health and well-being. While some people think that being overweight is the only unhealthy way to be, being underweight can also pose a health problem. When you are very skinny, it can be difficult for your body to maintain the muscle balance that is needed, and your muscles can become weaker over time. If you are underweight according to your BMI, using different balance training exercises and methods that help improve your posture will help you gain the muscle balance you need for a healthy body.
If your BMI shows that you are overweight, you don't want to do exercises that are designed to build muscle. You want to take part in exercises that are going to burn calories, such as cardio. This can be done on a regular basis, and it helps you to shed off the extra weight and burn calories rather quickly. Any exercise that is quick and vigorous will help you lose weight, and after some time with the routine, you'll start to see improvements in how you feel overall and in your self-confidence.
The Pros and Cons of the BMI
Advantages of BMI Testing
BMI testing requires no special training or education. The calculation is a bit complicated at first, but with practice, it can be done in just a few minutes. Also, the results are easy to understand. You just need to compare your score to the chart. BMI does not require you to take your shoes off or remove clothing, making it quick and easy.
Disadvantages of BMI Testing
Your body weight is made of muscle mass, fat, water, skeletal weight, and internal organs. BMI does not differentiate between these components, so it may not be accurate for everyone. Muscle and bone weighs more than fat, so if you are big-boned and muscular, your BMI may reflect an incorrect result.
