The Biomechanics Manual – Ben Yanes

The World's Simplest Guide to Human Movement in the Gym

Stop Guessing.
Start Knowing.

Steal the biomechanics blueprint that gives you total control over how you train, how you load movements, and how you target any muscle — without wasting years figuring it out on your own.

The Biomechanics Manual Cover – Ben Yanes

This Manual Will Help You:

Finally Understand
Why Your Training Works

Own Your Technique

Understand exactly why certain exercises work for your structure — so you stop copying others and start training smarter for your body.

Target Any Muscle

Learn how angles, grip, stance, and load path determine which muscles get challenged — so you feel every set where you actually want to.

Break Through Plateaus

When you understand the mechanics behind each lift, you stop spinning your wheels and start making real, predictable progress.

Train Without Guesswork

Build a foundation of principles that gives you lifelong independence — no expensive coaches, no contradictory YouTube advice, no confusion.

OKAY, I'M IN!

How This Manual Was Built

I Wasted Years Learning The Hard Way. You Don't Have To.

In today's fitness world, confusion around technique, training methods, and muscle targeting is everywhere. Most lifters spend years collecting advice from YouTube, Reddit threads, and half-baked influencer content — and still feel lost.

The attempt to learn often backfires. Frustration. Plateaus. Injuries from movements that never quite felt right. A nagging sense that everyone else figured something out that you haven't.

I built the Biomechanics Manual because that confusion is completely unnecessary. The principles governing human movement aren't complicated — they just need to be taught clearly, practically, and without the gatekeeping.

Once you understand the why behind your training, everything changes. Not because you're training harder — because you finally know what you're doing.

Who Is This For?

WHO IS THIS FOR?

The Dedicated Lifter

For the lifter who's been training for years but still isn't 100% sure they're doing movements correctly — and wants to fix that for good.

The Fitness Coach

For the coach who wants to actually understand why they're giving the cues they give — so they can help more clients and charge what they're worth.

The Beginner

For the beginner who wants to skip years of trial and error and build a rock-solid movement foundation from day one.

The Comeback Athlete

For the former athlete returning to training who wants to understand their body better now than they ever did during their competitive years.

THAT'S ME — I'M IN!

The Slow Way to Learn

The Worst Ways to Learn Biomechanics

Most lifters waste years on approaches that feel productive but keep them stuck.

Watch random YouTube videos and hope it clicks: This creates a patchwork of contradictory cues with no coherent framework — you end up more confused than when you started.

Copy what the biggest guy at the gym does: His structure, limb lengths, and injury history aren't yours. What works for him can wreck you — and you won't know why until it's too late.

Wait until you can afford a great coach: This burns time you'll never get back and keeps you permanently dependent on someone else's knowledge. You deserve to understand your own body.

You've been taught to collect techniques instead of principles — and that's why training still feels uncertain. I want to teach you a much better way.

I got serious about training the way most people do — obsessively consuming content, copying what I saw, and hoping the pieces would eventually fit together. They didn't.

The turning point wasn't training harder. It was finally understanding the principles underneath the techniques. When I stopped collecting random cues and started understanding biomechanics, my training changed permanently — and so did my ability to help others.

The Biomechanics Manual is the resource I wish had existed when I started. Written for real people who want to actually understand what they're doing in the gym — not just follow instructions blindly.

You don't need years of trial and error. You just need the right foundation. Allow me to give it to you.
