Is Higher FFMI Always Better?
Not always. A higher FFMI can reflect more lean mass, but it should be interpreted alongside health, performance, body fat level, and measurement accuracy.
Very high FFMI values may also be affected by inaccurate body fat estimates. If body fat percentage is underestimated, FFMI can look higher than it really is.
How to Improve Your FFMI
- • Train with progressive overload.
- • Eat enough protein consistently.
- • Use a smart calorie surplus if gaining muscle.
- • Sleep enough and manage recovery.
- • Track strength, body weight, and measurements over time.
