FFMI Chart for Easy Understanding
The FFMI chart helps you understand where your FFMI score fits compared to others. Here’s how the chart looks:
| FFMI Score | Category | What it Means |
|---|---|---|
| Below 18 | Low Muscle Mass | You might have less muscle and more fat. You may want to work on building muscle. |
| 18 to 24 | Normal Muscle Mass | This is considered a healthy, balanced amount of muscle. You’re in good shape! |
| Above 24 | High Muscle Mass | You have a lot of muscle compared to fat. This is common among athletes or bodybuilders. |
What is the Fat-Free Mass Formula?
To calculate your FFMI, we use the fat-free mass formula. This formula helps figure out how much of your weight is made up of fat-free mass (muscle, bones, etc.):
| Formula | Explanation |
|---|---|
|
Fat-Free Mass (FFM) = Weight – (Weight × Body Fat Percentage)
|
This formula finds your fat-free mass by subtracting the fat from your total weight. |
|
FFMI = Fat-Free Mass (kg) ÷ Height² (meters)
|
This final step calculates your FFMI by dividing fat-free mass by your height squared. |
