An online lean body mass calculator helps to find lean body mass (LBM) that depends on your gender, height, and body weight. Our LBM calculator calculates lean body mass by using the Boer, the James, the Hume, and the Peters equations. For weight-conscious individuals, this lean body weight calculator is a handy tool as it helps in estimating both LBM % and your body fat percentage.
You might have seen people who are fat but not muscular, and if you compare their body weights, you will find out that fat person has lesser weight than the muscular man. A fat person looks bulky due to extra fat in the body, while muscles possess more volume than the weight, and that’s why a person with muscles looks smarter but still has good weight; that’s because this person has a more lean body mass than the body fat. And now you know why it is important to know about your lean body mass.
Here you can explore how to calculate LBM (Lean Body Mass) by using lean body mass calculator with body fat percentage and a lbm formula, lbm standards, (lbm), lean body mass chart, and different other legitimate information-related LBM. So, let’s start with the basic definition of LBM.
According to the lean body mass (weight) definition, LBM is the weight of your body after deducting the weight of your body fat. In other words, it’s the weight of muscles, your bones, other body organs, and limbs without fat. Now as you know what lean body mass is, you might have got the idea of what is important in your mission of weight loss.
The extra body fat not just disfigure your body, it is also dangerous for your health and smooth performance of your daily body functions. So if you will calculate how much lean body mass and body fat you have, you can plan your diet and workout accordingly to improve your lean body mass and to reduce your body fat. So, enter the values into the above lean body mass calculator to find how much lean body mass muscle your body have!
Usually, Lean Body Mass (LBM) rages from 60 to 90 percent of body weight. A man with less than 75 percent LBM is said to be unhealthy, and for a woman, it is less than 68 percent. Athletes often have lean body mass (LBM) between 84 and 94 percent for men and 81 and 91 percent for women, which is said to be normal for trained individuals, although it is lower than the average for healthy people. If you are athlete, then the above lbm calculator will best way to determine how much LBM your body consists of for your gender, weight, and height. Studies depict that, it is not healthy, however, for a woman to have less than 8% body fat or a man to have less than 5% body fat. A body muscle calculator by calculator-online also uses the same standards to calculate lean body mass for different genders corresponding to various methods.
Calculating Lean Body Mass becomes easy with the above lean muscle calculator, but remember that LBM is different for different gender because the body structure and requirements are different for males and females. Normally, female body needs to have more body fat than males so the lean body mass will be lower than males. Let’s have a look at how to calculate lean body mass for male and females using lean body mass formulas, but before that let we tell you about the main equation of LBM or (eLBM).
LBM = BW – BF
Where;
The LBM formula’s that are taken into account for calculating LBM are as follows:
For Men:
0.407 × weight[kg] + 0.267 × height[cm] – 19.2
For Women:
0.252 × weight[kg] + 0.473 × height[cm] – 48.3
For Men:
1.1 × weight[kg] – 128 × ( weight[kg] / height[cm] ) 2
For Women:
1.07 × weight[kg] – 148 × ( weight[kg] / height[cm] ) 2
For Men:
0.32810 × weight[kg] + 0.33929 × height[cm] – 29.5336
For Women:
0.29569 × weight[kg] + 0.41813 × height[cm] – 43.2933
The peters equation is used to calclate LBM of children (up to 13-14 years old) and this equation is based on an estimated extracellular volume (eECV) as given:
eECV = 0.0215·W0.6469·H0.7236
eLBM = 3.8·eECV
Now from the formula’s, you can see how different the lean body mass is for males and females and children. And if you feel that you can’t remember these equations, you always have the option of using this simple and easy to use LBM calculator to calculate your lean body weight.
Thankfully, you come to know about lean body mass (weight) definition and you have also learned how to calculate lean body mass with equations. Now, you need to know how lean male body or female body is perfect or satisfactory. To know about how lean male body or female body should you according to gender, you can consult ideal lean body mass chart given below. And if according to the chart, you have less lean body mass and more of body fat, you need to try lean body workout to come back to perfect figures.
Look at the given lbm chart to know is your lbm is ideal or “what is lean mass your body has”.
| Gender | Age | Low(-) | Normal(0) | High(+) | Very High(++) |
| Female | 18-39 | <24.3 | 24.3 – 30.3 | 30.4 – 35.3 | ≥35.4 |
| 40-59 | <24.1 | 24.1 – 30.1 | 30.2 – 35.1 | ≥35.2 | |

The lean mass calculator calculates:
Note: Our lean body mass calculator supports both imperial and metric systems of units.
Generally, women posses more body fat as compared to men even if they have the same body mass index (BMI). Studies reveal that women need more body fat % for them to bear children. That’s the basic reason why they often have a less lean body mass as compared to men. Average women would have LBM between 69 to 75%, and for men, LBM is between 76 to 82%.
Experts referred these ranges “normal” for those who train. So, look at the above-mentioned lbm standards and use this simple, but highly accurate LBM calculator to know in which ranges your LBM is!
Also, you can try this smart bmi calculator to calculate body mass index (BMI) for men, women, teen, and child, this tool shows you the precise measurements related to BMI.
Sometimes lean body mass (LBM) also referred to as a “lean mass,” likely the source of the term “lean muscle”, it is the total weight of an individual body minus all the weight due to his/her fat mass.
Lean Body Mass (LBM) = Total Weight – Fat Mass
Unlike “lean muscle”, Lean Body Mass (LBM) the term that correctly uses the word ‘Lean’ as it elaborates the entire weight of an individual body minus fat. That’s the reason why it is also said to be as “Fat-Free Mass.”
Remember that the weight of organs will not change much, but bone density is something that will decrease over time and doesn’t significantly affect the weight of your LBM.
The two most major areas to focus on with LBM are body water and muscle mass. Well, the online body muscle calculator readily determines the lean body muscle mass percentage as well as body fat %.
When individuals talk about gaining muscle by consuming more protein or muscle building workouts, what they are really discussing about gaining or building their Skeletal Muscle Mass. However, this is just because of the three major muscle types that are cardiac, smooth, and skeletal. Skeletal Muscle Mass is the only type of muscle that human body can actively grow and develop through proper exercise and nutrition. But, keep in mind, Skeletal Muscle Mass is one part of your LBM or Lean Body Mass and another influencer is water. You can try the skeletal muscle mass calculator to calculate skeletal muscle mass.
No doubt, lean body mass and skeletal muscle mass both has a significant difference, so how you come to know how much each you have?
So, let’s begin with the term what not to do: don’t utilize a scale to determine changes in Skeletal Muscle Mass.
The most prominent method to estimate muscle gain is by using a combination of the number on the scale and advice from fitness magazines.
The problem with using a scale to determine progress is that there are several factors which influence an increase in body weight, a few of which are mentioned below:
Well, the best way to calculate what is happening to your Lean Body Mass (LBM): you just have to getting your body composition analyzed. Keep in mind, without testing your body composition, there will no other way to know what any gain/loss in your body weight is due to. Also, give a try to this lean body mass calculator to figure out the muscle mass of your body according to standard formulas of LBM.
The methods that will use for body composition analysis will at the minimum divide your body into LBM (this can be indicated to as Fat-Free Mass) and Fat Mass. These methods are:
No doubt, each of them is packed with pros and cons and even accuracy may vary depending on a number of factors, so before taken such methods into account you ought to consult with your doctor!
If you want to get in more depth body composition analysis, then you would have to look to two more sophisticated methods, which include:
These methods tell you how much fat you have and even also differentiate your Skeletal Muscle Mass from your lean body mass (LBM).
Well, it’s to get back to our originally, three statements, let’s take a look!
Hitting the gym is not enough at all; you should have to consider what you’re consuming before you measure your progress. Your diet plays a key role in measuring your muscle gains.
Refer to a given list of foods that hinder muscle development:
Once you stick to your lean muscle mass journey, account for this ideal lean body mass calculator to know your actual LBM percentage, this will helps you to reach your lean mass goals.
You can readily measure muscle weight gain by tracking your LBM (lean body mass) over time. So, use the above 100% free muscle weight calculator to calculate your muscle weight (mass) consistently and accurately. LBM is said to be as everything in your body besides fat, organs, muscle, bones, water etc. The University of California, Berkeley is using a body fat scale, which uses bioelectrical impedance technology to measure your body fat or (LBM).
Lean Body Mass or LBM is determined as the difference between the total body weight and body fat weight. The range of LBM is referred to be healthy as around 70 percent to 90 percent with women being towards the lower end of the range and for men higher.
To calculate maximum LBM, stick to the given formula:
Maximum LBM = (Your Height in Inches – 70) x 5 + 160
Simply, put the values into the above formula to find your maximum LBM.
Normally, greater muscle mass is something that has positive health effects. But, remember that if you have high muscle mass, you might be slow down muscle loss and protect your physical ability. Also, skeletal muscle improves your overall metabolism. Studies depicts that skeletal muscle burns more calories at rest as compared to fat.
Remember that you should have to target a specific muscle group on a particular day. Also, you cannot work on the entire body together. All you need to correct your form and increase your repetitions with time. Well, it will take 4 – 8 weeks for your muscles to get toned as it depending on the intensity and even the consistency of your workout.
Keep in mind, lean muscles can be built by consistent weight lifting and strength training sessions – and simply through providing your body with the fuel and nutrients that are necessary to heal and grow. However, men are likely notice fast outcomes as compared to women because they are pumped by testosterone and the growth hormone. Also, more time will be required to see more significant changes in your muscle sizes.
If you indicate an individual as lean, it means that he/she is thin but looks strong and healthy. For instance, athletes are lean and fit. If meat is lean, then remember that it doesn’t have very much fat.
Well, individuals with leaner bodies tend to be healthier, more injury resistant, more flexible, and even have quicker cardio recovery times than the individuals who stick to active lifestyle with higher level of body fat.
If you’re running consistently and also adding strength training, then you might lose excess flab, but there’s likelihood of gaining muscle at the same time. As an outcome, your body is getting stronger, fitter, and even leaner, but the scale may refer to as a change. In few cases you may even see a weight increase.
According to optimistic studies, LBM is composed of all of the muscles, bones, organs, tissues, and water in the body excluding fat. When you hear about lean body mass, you may think of muscle. LBM is something that certainly includes our muscle mass, but even also includes everything else our body is made up of instead of fat. Keep in mind, 3% for men and 11% from women is immensely important for the proper functioning of the body.
These simple things assist you to increase lean body mass faster:
Lean body mass (LBM) is very important as it contributes to looking great or being stronger. Various studies reveal that the greater amount of LBM you have, the greater your Basal Metabolic Rate (BMR) will be. Means, individuals with greater amounts of Lean Body Mass will have greater energy expenditure while doing nothing, assisting to avoid calories imbalances, and ultimately, obesity. So, consider the ideal body lean mass calculator to find your lean body mass percentage according to different formulas, and ahead to doctor for optimal lbm.
These are the things that help you t get leaner and fitter.
Best foods for gaining lean muscle mass:
Muscle mass is not the same for every individual and may vary depending on age and fitness level. According to the 2000 study published in the Journal of Applied Physiology, the amount of muscle you have in your body will decrease as your age and dramatically after age 45. And, Classic study in the Journal of Sports Sciences reveals that fitness and type of activity make a difference in muscle mass; remember that bodybuilders having greater muscle percentage as compared to endurance athletes. If you want to attain muscle lean mass, then use an online ideal lean muscle mass calculator that calculates the lean muscle mass percentage and boy fat percentage, with this figure it becomes easy to reach ideal muscle mass goals.
Lean body mass is said to be a measure of the total weight of a person’s bone and muscle minus their fat weight. In another term, lean body mass is referred to as a person’s total weight minus their total fat mass.
In terms of diet, the lean body mass of an individual determines how much protein he/she needs to consume on per day to maintain muscle mass. The evidence of this method comes with the studies in which nitrogen balance is measured in people who relied on a very low-calorie diet (VLCD) to induce weight loss.
