The Claim
The method used to measure muscle mass (fat-free mass, lean muscle mass, or skeletal muscle mass) is not associated with the magnitude of reported hypertrophy from resistance training in healthy adult males, indicating that these metrics are interchangeable for tracking overall muscle gain in this population.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
No matter which way you measure muscle growth—whether you count all non-fat weight, lean tissue, or just skeletal muscle—you get pretty much the same result when guys lift weights. So, you can use any of these methods and still track muscle gain accurately.
