Now, let's suppose we are calculating the LBM for 65 KGs. Now as soon as you enter the weight in Kilograms, it instantly converts into pounds but in a different column automatically. Then below is a column where you have to mention your body’s fat but percentage wise. When that is done, you get the result in accordance to which you can decide if you have to increase your LBM or work on keeping it at the constant level.

For athletes, the LBM level must be 81 and 91 percent (Women), and when it comes to men, the lean body mass level has to be in between 84 and 94 percent. If the Lean Body mass of a person is less than that, then the range is considered to be unhealthy, and the ways given above should be opted for to increase the level of the lean body mass in the body. The usual reason why women tend to have a standard LBM lesser than men is because of the fat percentages in their bodies as compared to that in men. The fat level or percentage in the bodies of men is much lesser than that in the women, and the necessary explanation that can be given behind it for the reasoning purpose is that they have to bear children. So their average LBM level has to be a bit lesser as compared to men, to stay in the healthy range and to have a less fat level but a very balanced LBM level and to maintain muscles as well.

However, do remember that the percentage and levels might vary from age to age as well. This is mainly because physically, aged people are way more different than younger people. They tend to have more body fat. Even if their weight is all appropriate, their LBM level might not be at the desired level.

Referring to the sample taken above (The picture), the calculated lean body weight calculator in the image, as a result, shows that it falls in the ‘’unhealthy’’ range and measures must be taken to improve it.
