So it seems that science say that I will not gain any muscle from this point. I'm 91kg, 1.78m with 14% bf. I know I've been gaining slow lately, but I don't think this is my genetic limit yet.

I haven’t looked at the study, but I assume the authors reported the mean and the standard deviation of the mean (what you call the “error bar”). It is possible that a few subjects (around 32%) had values farther from the mean than one standard deviation. So, technically, “Those are the two biggest guys in the sample size” is wrong." The range is likely to be 2-3 standard deviations (95-99% confidence interval), not 1. That leaves the percent of people outside of that range at 5% or less, which makes Lyle's theoretical example pretty reasonable. “You’re a little off on the statistical side, but it’s a minor issue.

You're a little off on the statistical side, but it's a minor issue. I haven't looked at the study, but I assume the authors reported the mean and the standard deviation of the mean (what you call the "error bar"). It is possible that a few subjects (around 32%) had values farther from the mean than one standard deviation. So, technically, "Those are the two biggest guys in the sample size" is wrong. Nonetheless, your figures and your analysis supports your point well and are insightful. Thanks much, -CJ Lyle,

Is the ceiling FFMI the same for females? Thank you.

In case this sounded ambiguous, I meant in the body, not in muscle gain. Meaning, if a guy's training and staying at the same weight, but lifting hard, will his contractile muscle mass increase while fluid decreases to maintain that same weight? “Also, if the same ceiling applies in both cases, for an advanced or even intermediate trainee not gaining/trying to gain mass for a while but still training with intensity, is there a shift from sarcoplasmic to myofibrillar mass?”

When you or Alan or Casey are talking about these genetic potentials for muscle gain and acheivable levels of gains per week or per month, are you referring to myofibrillar hypertrophy or sarcoplasmic hypertrophy? I ask because the difference can be pretty significant depending on if you're a bodybuilder or a performance athlete. If you're referring to one of them, how different are rates/ceilings for the other? Also, if the same ceiling applies in both cases, for an advanced or even intermediate trainee not gaining/trying to gain mass for a while but still training with intensity, is there a shift from sarcoplasmic to myofibrillar mass? After checking your other articles about periodization for bodybuilding, it seems like minutiae but any more information on the matter would help. If there's a lot more to the topic, would you be able to point me toward a reliable source of information? Yash Hey Lyle,
