Track Progress

Monitor your FFMI over time to ensure you're gaining muscle, not just weight.

Nutrition Matters

Adequate protein intake (0.8-1g per lb of body weight) supports muscle growth.

Recovery is Key

7-9 hours of quality sleep optimizes muscle recovery and growth.

Calculating your body composition...

What is the Use of Our FFMI Calculator?

Muscle measurement is accurate.

Obtain an accurate view of your muscle growth by calculating your lean body mass in reference to your height which is not affected by the presence of body fat.

Goal Setting Easy

With your FFMI score, you can now create a goal of muscle gain (or even competition prep), maintenance or even loss, specific to your own body composition.

Keep a Records of Your Progress

Keep track of your muscle mass by measuring it regularly to observe the actual outcome of your exercises, diet and rest plans.

Compare and compete

Compare your FFMI with the norms of fitness or your fellow people and you will have a standard to motivate and improve yourself.
