Questions, answered plainly.

Two files, immediately: the complete PDF and the complete audiobook as an MP3. Not a sample, not the first three chapters with the useful part behind a second payment. Both open on anything that reads a PDF or plays an MP3 — phone, tablet, laptop, car. No app to install, no account to keep alive.

No, and that's deliberate. The narration is an adapted script, usually shorter than the manuscript, because prose written for the eye reads badly to the ear. The claims are the same and the confidence ratings are the same. What doesn't survive the trip is the apparatus — tables, superscript markers, the reference list — which is what the PDF is for.

Vol. 0 is free. The other fifty volumes are $12 each, field guides $7, cookbooks $12, programmes $29 — all in US dollars. Three bundles: Foundations (Vols 1–6) at $49, The 50 Volumes at $149, and The Complete Library — all ninety-seven products — at $199. That's the whole price list. If prices change, the email list is told before the store page is.

Checkout runs on Payhip, which acts as Merchant of Record — they take the payment, issue the receipt, and handle refund requests under the terms shown at checkout. Read those at the point of purchase rather than trusting a summary on this page. If a file is broken, missing, or the wrong one, email [email protected] and it gets replaced, which is usually faster anyway.

Nelson Sequeira, a certified fitness professional teaching group exercise since 2001, professionally since 2006, across Portugal, Bahrain and the UAE. He is not a licensed nutritionist, physician, physiotherapist or psychologist. That sentence sits at the bottom of every page here because it is load-bearing, not decorative — a trainer performing as a clinician is one of the main ways people get hurt. Twenty-five years buys pattern recognition. It does not buy a licence.

None of it is medical advice, and it cannot be. It's education: what the research found, how confident the field is, and what that implies for a normal week. Nothing in it replaces qualified medical or clinical care. See a licensed professional when something needs examining rather than explaining — pain that won't settle, a diagnosis, a medication, anything hormonal, signs of disordered eating. The volumes name the referral each time.

Then read the referral before the recommendation. Consult a licensed healthcare professional before starting any new training, nutrition or recovery programme — an OB/GYN for pregnancy and postpartum, a physiotherapist for injury and persistent pain. Vol. 30, Vol. 33 and Vol. 35 exist and are educational, written so you can walk into that appointment knowing what to ask. They are not a replacement for the appointment.

Vol. 31 covers youth training, and yes — supervised resistance training for children has decent evidence behind it. The “it stunts growth” line is one of the myths that volume takes apart. It also asks for paediatrician clearance and adult supervision, because a twelve-year-old is not a small adult with a smaller barbell. The rest of the Library is written for adults.

Because it carries a citation you can follow. Sources are taken in order of strength: systematic reviews and meta-analyses first, then randomised controlled trials, then cohort and observational work, then position stands from bodies like the ACSM, NSCA, ISSN, WHO and ACOG. Opinion is labelled opinion, anecdote as anecdote. Watching people train for twenty-five years is worth something. It is not worth a meta-analysis.

Every major claim is marked settled science, strong evidence, emerging, or contested. When experts disagree you get the disagreement — both sides, and why — rather than the side that makes the tidier paragraph. Where a finding rests on one small trial, the sample size is on the page next to it. A contested claim is never dressed up as settled.

The audiobooks are narrated by an AI voice. That is disclosed on every product page, in the audio itself, and here. It isn't Nelson's voice and it isn't pretending to be. Research assistance and production tooling are AI-assisted too — that is how one person ships a catalogue this size — but a human chooses every claim, checks every source, and is accountable for all of it.

It gets corrected in writing rather than quietly edited out. Every significant claim is logged across volumes, and the emerging or contested ones are re-checked as the literature moves. A definition cannot be silently changed later — it either matches the earlier volume or carries a footnote saying what replaced it and why. If you think you've found an error, send it to [email protected]; that is a favour, not a complaint.

Payhip delivers the download the moment payment clears and emails you a link as well. Save the files somewhere you'll find them again — what you own is a set of files, not a login. If a link stops working or a drive dies, email [email protected] from the address you bought with and it gets sent again. No proof-of-purchase interrogation.
