How to Build Muscle: A Beginner's Guide
Everything that decides whether you build muscle, in the order it matters: training, food, recovery and time, with the research behind each number.
Research-backed
Every claim that needs a source has one you can open.
Stanford Journalism Program
Journalism student at Stanford University, where he studies international relations and Asian-American studies alongside the Stanford Journalism Program. He checks the sourcing on Gritwright guides: that every number is traceable to the study it came from, that the study says what the guide claims it says, and that nothing has been quietly rounded in our favour.
Noah does not write the guides. He is the reason you can check them. Every guide here goes through the same pass before it publishes: each source is opened and read, not quoted from a search result snippet, and each number is followed back to the paper that produced it. Where a source turns out to be unreachable, the claim resting on it comes out of the guide rather than staying in with a hopeful link attached.
What he is hunting is narrow and specific, and it is the failure mode that gets past everyone: a figure copied from another article rather than from the study, a finding stretched a little past what the researchers actually reported, a citation that quietly supports a weaker version of the sentence sitting above it. That pass covers the whole archive, from the training research to the relationship guides. It is also worth saying what it is not. Checking the sourcing is not the same as assessing the medicine: where a guide makes a clinical or physiological claim, the label on that guide says which kind of check it actually received.

The number the research supports, why it is lower than the industry says, when it goes up, and whether the 30 grams per meal rule is real.

What the meta-analyses say about sets per week, rep ranges and how close to failure you need to go, and what to do with the numbers.

Body recomposition is real but not for everyone. Who it works for, the protein and deficit numbers behind it, and how to tell it is happening.

How big the surplus should be, how fast the scale should move, and what the research actually says about whether eating more builds more muscle.

Rejection activates the sensory pain regions of the brain, and the standard advice to write it all out can make recovery worse. What the evidence supports instead.

The apps are measurably good at one thing and measurably bad at several others. Here is what the survey data and the psychology research actually establish.

Refusing is harder than anyone asking you realises, and there is research showing exactly how much. What that means for how to say no, and what silence costs.

Researchers who coded 124 newlywed couples found the outcome was visible in how a disagreement started. Here is what that means for your next one.

Most couple conflicts are never resolved, and the research says that is normal. What separates couples who last is not solving them but how they talk about them.

The largest study ever run on this question compared hundreds of variables across 11,196 couples. What predicted happiness was not what the advice columns say.

The question is usually asked wrong. What the research says about ambivalence, about why you are a biased judge of it, and what really predicts an ending.
