Muscle mass includes the weight of the muscles in your body in kilograms or pounds.
Muscle mass refers to the body's soft tissue, excluding water, fat, and bone components. The human body comprises three types of muscles: smooth, cardiac, and skeletal. Muscle mass comprises all the muscles.
Tracking muscle mass is essential for women to achieve specific fitness goals, like weight loss, toning, or building muscle. By regularly monitoring your muscle mass with a muscle mass percentage calculator, you can make informed decisions about your diet and exercise routines, ensuring the body's overall well-being.
Ideal Muscle Mass Percentage for Women
The ideal muscle mass indicates the perfect proportion of the muscle your body needs according to age and gender to perform daily tasks. A low muscle mass indicates that you have low muscle proportion as needed at your age.
In contrast, a high muscle mass figure indicates that you have more-than-average muscle composition, which can also hinder the optimal functioning of your body. Here, we’ll explore the ideal muscle masses for each age group so you can judge where improvement is needed after using an ideal muscle mass percentage calculator.
Muscle Mass Percentage by Age for Females
| Age | Muscle Mass Percentage |
|---|---|
| 18 - 35 | 31 - 33% |
| 36 - 55 | 29 - 31% |
| 56 - 75 | 27 - 30% |
| 76 - 85 | < 26% |
During the years between 18 and 35, women are usually at their peak in terms of muscle mass. Therefore, regular exercise and a balanced diet can help maintain a higher percentage of muscle proportion in the body.
However, as they progress to their forties and fifties, muscle mass begins to decline because of the natural aging process. Factors like hormonal changes and menopause can accelerate muscle mass loss leading to conditions like sarcopenia. Therefore, increasing protein intake and ensuring optimal physical activity is important.
What’s a Good Muscle Mass Percentage for Your Fitness Goals?
More muscle mass contributes to better metabolism, which leads to higher weight loss. A good muscle mass percentage varies depending on your fitness goals. Maintaining muscle mass between 30% and 40% for weight loss ensures you burn calories effectively while preserving strength.
If your goal is toning, aim for 35-45% muscle mass to achieve a lean, defined physique. Targeting a higher percentage, around 45-55%, is ideal for building muscle, as it supports strength gains and a more muscular appearance. Customizing your muscle mass percentage to align with your specific goals helps optimize your workouts and achieve the desired results. Monitoring your muscle mass allows you to adjust your training and nutrition for optimal progress.
How to Use a Muscle Mass Percentage Calculator: A Step-by-Step Guide
There are numerous ways to calculate muscle mass percentage. You can either use medical equipment, measure certain body parts, or calculate body fat percentage. However, the simplest way is to use a muscle mass percentage calculator.
-
Navigate to the muscle mass calculator page, and you’ll be prompted with an interface where you can input your details to calculate the muscle mass.
-
First, input your gender by selecting an option from the menu.
-
Next comes the weight input box. Since this is a muscle mass kg to percentage calculator, you can input your weight in kilograms or pounds. Fill in the weight box and move to the next step.
-
In the next section, enter your height in centimeters, inches, or feet. Once all the details are entered, click on calculate to get your muscle mass.
Several factors, including age, activity level, gender, hydration status, and body composition, influence the accuracy of a muscle mass percentage calculator. For instance, if the calculator doesn’t factor in age or exercise frequency, it can underestimate the overall muscle mass. Similarly, ignoring things like hydration and body composition can also lead to inaccurate results.
Formulas Used in Muscle Mass Calculators
Muscle mass percentage calculators use the following formula to calculate the muscle mass percentage.
Formula for measuring the muscle mass in females:
LBM=(1.10×weight in kg)−(128×(weight in kg/ height in cm)2)
Formula for measuring muscle mass in males:
LBM=(1.07×weight in kg)−(148×(weight in kg/ height in cm)2)
Since muscle mass is 40 to 50 of your body weight [4], you can multiply the resulting figure by 0.4 or 0.5 to get the final muscle mass. Note that the above calculation method is only an estimation, as measuring your exact muscle mass without expensive technology is impossible [5]. Their quick summary is up ahead.
Bioelectrical Impedance Analysis (BIA) is famous for its convenience and accuracy. The approach estimates muscle mass by measuring body resistance to an electrical current. However, hydration levels can affect accuracy[9].
Similarly, Dual-energy X-ray Absorptiometry (DEXA) scans offer precise results by assessing muscle, fat, and bone density through low-level X-rays, making it ideal for detailed body composition analysis. [8]
Skinfold calipers measure the thickness of skinfolds at various body sites to estimate body fat, from which muscle mass can be inferred. Though less precise, they are cost-effective and accessible. However, the most accurate test is an MRI test, which uses magnetic imaging to analyze muscle proportion.
Improving Your Muscle Mass Percentage
Maintaining and building muscle mass is essential to ensuring the metabolic and physical health of the body. Strength training has a lot of say in the matter [6], but proper nutrition is uncompromising.
Nutrition Tips to Build and Maintain Muscle Mass
Consuming protein-rich foods is crucial when targeting muscle growth and improving muscle mass percentage calculator results. To support muscle repair and growth, include lean meats, fish, eggs, and plant-based proteins. Ensure a mix of carbs, fats, and proteins provides sustained energy and essential nutrients at regular intervals throughout the day. Furthermore, you can augment your diet by utilizing muscle growth-promoting proteins like creatine and branched-chain amino acids (BCAAs).
Workout Routines to Boost Muscle Mass
Focus on exercises like squats, deadlifts, and bench presses, which engage multiple muscle groups and build overall strength. Progressively increasing the repetitions or weights in weight lifting sessions offers a continuous challenge and promotes muscle mass growth. Pilates and HIIT workouts are also effective in gaining muscle mass. However, exercising without rest can do more harm than good. Therefore, allowing your body to relax one or two days a week is essential.
Conclusion
A muscle mass percentage calculator helps you track your muscle mass easily so you can make better and more informed decisions about your fitness journey. Though there are precise methods as well, but they are not always easy on the pocket.
Consistent tracking, combined with a balanced workout routine and nutrition intake, will help you elevate not only your physical appearance but also your confidence and long-term health. So be patient and embrace the challenge!
