The Claim
Untrained individuals can expect to gain approximately 1.5 kg of fat-free mass over 8–12 weeks of resistance training, with gains plateauing significantly in trained individuals, and the upper natural limit of fat-free mass is typically below 25 kg above baseline.
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.
If you've never lifted weights before, you can expect to gain about 1.5 kg of muscle in 2 to 3 months of training—but if you're already strong, you won't gain much more. Also, even with perfect training and diet, most people can't naturally build more than 25 kg of muscle above their starting point.
