A $5 book by Dan Rodgers

Why swimmers who train hard stop getting faster

There is a point in every swimmer's stroke where it can no longer hold its shape under load. Past that point you are still working. You are still tired. But you are not conditioning the stroke you want — you are rehearsing the one that collapsed.

This book shows you where your point is, how to find it in one session, and what to do about it.

Written by Dan Rodgers — swim coach, Perth. Fifteen years on pool decks.

The plateau nobody explains properly

You swim three or four times a week. You have done the drills. You have watched the videos. Your 100 metre time has not moved in two years.

The usual explanations are that you need to work harder, or that your technique is inefficient, or that you should focus on being longer and more streamlined. You have probably tried all three. If any of them were the answer, they would have worked by now.

Here is what is actually happening, and it is mechanical rather than motivational.

A stroke only makes you faster if it moves an optimal body of water. Every stroke that fails to move that water no longer conditions you to improve.

That sentence is the whole book. Above a certain effort your body stops being able to hold the mechanics that move water well. It reorganises itself to survive the effort instead. The pace might hold for another lap or two, which is what makes this so hard to spot, but the stroke underneath it has already changed.

That point has a name. It is your technical threshold, and almost every hard session you have done was spent above it.

Three ways a stroke gives out

Collapse is not one thing and it does not look the same in everyone. It has three signatures, and knowing which is yours changes what you should do on Monday.

Balance collapse

  • Hips sink
  • Legs drop
  • Propulsion gets diverted
  • Head lifts
  • Breathing turns disruptive

Pull collapse

  • Elbow drops
  • Pull shortens
  • Catch weakens
  • Pull exits early
  • Stroke rate rises to compensate

Timing collapse

  • Rushed breath
  • Front-end glide disappears
  • Pull starts too early
  • Pull starts too late
  • Dead spots appear

If your stroke rate climbs late in a set while your pace does not, that is not you digging deep. That is the compensation. It is the clearest free signal you have.

The part that will annoy your coach

Nearly every major name in swim coaching gives beginners the same first instruction: get longer, get flatter, reduce drag. Streamline.

For most swimmers that is the wrong first instruction, and here is why.

Resistance rises very steeply with speed. Which means drag is not equally important at every level — a swimmer has to already be producing substantial force before drag becomes the thing holding them back. Chase streamlining before you can hold a stable platform and you are optimising the one variable that is not yet your limit.

Streamlining is an outcome, not an instruction.

Fix balance so the body stops spending propulsion on staying afloat. Then improve how much water the stroke actually moves. Body position tends to arrive on its own, because a swimmer who is balanced and moving water well is, by consequence, in a better shape through the water.

This is not a style preference. It is an order of operations, and getting it backwards is one of the most common reasons capable adult swimmers stay stuck.

What is in the book

Forty chapters in seven parts, plus four appendices. Around 135 pages.

One — the problem nobody names

  1. The session that made you slower
  2. Distance ÷ time, and nothing else
  3. Function before appearance
  4. Why the drills did not work
  5. What a coach on the pool deck cannot see

Two — the mechanism

  1. Three forces, one hierarchy
  2. Balance is not body position
  3. The heresy: streamlining is an outcome
  4. Load: what a stroke is actually for
  5. Orientation over perception
  6. Aim, orientation, indicator
  7. The circle of control

Three — the stroke, element by element

  1. The four phases of the stroke
  2. Balance and alignment, in detail
  3. Head position
  4. The glide, and why reaching ruins it
  5. Leading arm drop
  6. The catch, and why entry is not the point
  7. Pull timing
  8. The pull back end
  9. Applied range of motion: work, not speed
  10. The pause finish, and reading the exit

Four — breathing

  1. Breathing is a balance problem
  2. The exhale and the inhale are different jobs
  3. The rushed breath
  4. Patterns, and the breathless swimmer

Five — kick, rotation and consistency

  1. What the kick is actually for
  2. Hip rotation and its timing
  3. Consistency, and why it beats any single stroke

Six — the threshold

  1. The technical threshold
  2. Three ways a stroke collapses
  3. Why collapse happens
  4. Load the stroke, not the fatigue
  5. Progressive threshold development

Seven — doing it

  1. Find your collapse point
  2. Filming your stroke properly
  3. Reading your own stroke
  4. Choosing your one focus area
  5. The next twelve weeks
  6. When to get another pair of eyes

Appendices

  1. The corrections, arranged by the fault they treat
  2. Drills and sculling
  3. If you have been told…
  4. The rules

Who wrote this

Dan Rodgers

Dan coaches swimming in Perth, one-on-one and by video, for adult swimmers and triathletes. He is not an Olympian and does not pretend to be. What he has is fifteen years of watching the same faults appear in the same order, and a framework built out of that rather than borrowed from anyone else.

He also builds the analysis himself. He spent a year with an engineering team trying to automate stroke scoring from video, got it to about fifty percent accuracy on the thing that mattered most, and stopped rather than spend another two years making it nearly work. That failure is in the book, because it is the clearest evidence he has for why judgment still has to be human.

After the book

The book will show you what to look for. Some people want someone to look with them. Dan reviews footage directly and sends back an annotated video with his voice over it — the same thing his in-person clients get.

Questions

I am a beginner. Is this too advanced?

No, but be honest about where you are. If you are still working on being comfortable and level in the water, the balance chapters are exactly where you should start and the threshold work can wait. The book says so where it applies.

Do I need to be able to film myself?

Not for the book. The threshold test in chapter fourteen needs a pool and a watch, nothing else. Filming makes chapter fifteen far more useful, and the guide for doing it properly with a phone is included.

Is this just another drill book?

No, and that is deliberate. Drills are in part four only, after the diagnosis. A drill applied to the wrong problem, or loaded above your threshold, is how most swimmers end up with a drawer full of drill lists and the same 100 metre time.

Will this take seconds off my time?

Nobody honest can promise you that, because your body, your history and your constraints are yours. What the book gives you is the mechanism and a test you can run yourself. If the mechanism does not describe your swimming, you will know within a week, and the refund stands.

Freestyle only?

Yes. The framework generalises, but every worked example is freestyle and the book does not pretend otherwise.
