Bodyweight

This is a simple concept. The body weight is your body’s mass, it is the number you see on the scale when you weigh yourself. By definition, body weight is a measurement of force due to gravity. Nothing about this definition talks about body mass or composition. So how are they related?

Body Mass Index (BMI)

When you measure BMI you are measuring the human body’s shape based on its weight and height. Therefore, to keep it simple, it means measuring the body’s size. It is used as a reference to label body mass as overweight or underweight or normal. Your BMI can indicate if you need to lose, gain or maintain weight at the moment. 

Even when it does so, the BMI does not take into consideration what the human body is made of when it comes to lean mass weight and fat weight. This is where the role of body composition is important.

Body composition

The body composition, as the name shows, is a test that shows what the body is made of in terms of fat, bones, water, and muscles. It is important to know your body composition for many reasons:

1. Knowing your body composition gives you lots of information about your health

If you are in a healthy weight range, but you have a sedentary lifestyle, you are probably not a healthy person. Not getting enough exercise (like over 150 million Americans) can make you experience heart-related problems and diseases such as heart disease, high cholesterol and diabetes. In this situation, body composition is an indicator that can tell you whether the percentage of fat in your body is within the healthy range, which is 10 to 20% for men and 18 to 28% for women. Knowing the percentage of fat in your body can help you take many preventative solutions to avoid diseases and problems related to an unhealthy composition.

2. Your body composition can tell you a lot about your strengths and weaknesses

Muscle imbalance is more than common for everyone, and doing a body composition analysis can help understand the strengths and weaknesses in your body. Knowing so will allow you to decide what parts of your body need more attention.

3. Your body composition can help you adopt the right workout approach

When you know how much fat and muscles you have in your body parts, you can know which ones need more attention and training. This will help you decide on a training approach targeting the weakest parts to strengthen them. For example, if you have high levels of fat in your body, you might need to do more cardio workouts to get rid of them.
