Read this before anything else
Nelson Sequeira is a certified fitness professional. He is not a licensed nutritionist, physician, physiotherapist or psychologist. Nothing in this Library is medical advice, diagnosis or treatment, and nothing in it replaces qualified clinical care. If you are pregnant or postpartum, managing a chronic condition, taking medication, or returning from injury, speak to a licensed healthcare professional before you change how you train or eat.
Before you buy
What do I actually get when I buy something?

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.

Is the audiobook just the PDF read aloud?

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.

Do the volumes stand alone, or do I need to start at Vol. 1?

Each volume stands alone. Fifty of them stack into one curriculum, but nothing is written assuming you did the homework — where a term was defined earlier it gets defined again, with a pointer to the volume that did it properly. Vol. 1 teaches you to read a study, which makes every other volume land harder. That makes it a good idea, not a prerequisite.

Which one should I start with?

Vol. 0 — The Manifesto. Free, complete, audiobook included, and there is no upsell buried in it. It's the argument for the whole project and the fastest way to find out whether the voice suits you. Some people read it and walk away, which is the point of putting it first. After that, Start Here routes you by what you're trying to do rather than by volume number.

Can I read it on a Kindle, and can I print it?

Both, with one caveat. The PDF is laid out for a page, so Send to Kindle works but a small e-ink screen will have you pinching and scrolling; a tablet is kinder. Printing is fine — it's your file. Each volume carries a one-page Quick-Reference Card built for exactly that: fridge, gym bag, back pocket.

Money
What does everything cost?

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.

Are the bundles actually worth it, or is that just bundle talk?

Do the arithmetic yourself. Bought one at a time the ninety-seven products come to $1282. The Complete Library is $199. The fifty volumes are $600 separately and $149 together; Foundations is $49 against $72. The discount is real because a folder costs the same to ship whether one person takes one book or all of them.

Is there a subscription?

No. There is nothing to renew and nothing to cancel. You pay once and the files are yours afterwards. For comparison, and because comparison is the whole point of this Library: Examine+ is $180 a year and MASS Research Review is $299 a year. Both are excellent. Both stop the day you stop paying.

Can I get a refund, and what if a file is wrong?

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.

Credentials and safety
Who wrote this, and what is he not?

Nelson Sequeira, a certified fitness professional with more than fifteen years 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. Fifteen years buys pattern recognition. It does not buy a licence.

Is any of this medical advice, and when should I see someone qualified instead?

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.

I'm pregnant, postpartum, managing a chronic condition, or coming back from injury.

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.

Are these suitable for kids and teenagers?

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.

How it's made
How do I know a claim isn't just confidently stated?

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 fifteen years is worth something. It is not worth a meta-analysis.

What do the confidence ratings mean, and what happens when evidence is mixed?

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.

How much of this is AI?

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.

What happens when something in here turns out to be wrong?

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.

Practical
How is it delivered, and what if I lose the files?

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.

How do I reach Nelson?

[email protected], read by a person. Instagram, YouTube, Pinterest and Facebook are all @sequeiralibrary. Health questions get a referral rather than improvised advice, for the reasons in the safety section above.

What does the email list actually send?

One cited idea a week, occasionally two, and releases announced first. Never a countdown timer. Emails come from [email protected]. Your address isn't sold, rented or shared, ever, and the unsubscribe link is at the bottom of every email in a size you can actually read.
