It’s commonly believed that myonuclei – the “control centers” of muscle fibers – are added to muscle fibers when fibers grow, but aren’t lost by fibers when they shrink, facilitating muscle re-growth. This is a proposed mechanism for the phenomenon of “muscle memory.” However, a recent review suggests that the data is less conclusive than people may realize.
Genetics and Strength Potential
A recent study told people they had either a good or bad genetic draw for aerobic exercise or hunger and satiety. Manipulating the subjects’ beliefs about their genetics changed both their objective and subjective responses to subsequent testing. This study builds upon prior literature showing that expectancy can influence outcomes to a surprising degree.

Just a quick recap of the background information from Part 1: Of the available models for predicting your drug-free muscular potential, muscle:bone ratio is probably the best option, but Dr. Casey Butt’s calculations are based on similar principles, and are much more user-friendly, so that’s what we’re going with for predicting muscular potential. Strength is
What you’re getting yourself into: 3,300 words, 11-22 minute read time Key Points: 1) Drug-free muscular potential is influenced by the size of your frame. 2) Strength is a function of neural factors and muscular factors. Once you’ve hit a point of diminishing returns for the neural factors, your strength potential will be determined by how much muscle you can build. 3) Based on a few simple calculations, you can get a pretty good idea of your muscular
