“The only benchmark is the version of you that stopped caring.”

Start here

Four moves, then you are running

Step 1

Work out your numbers

The figures on page one are the worked example, not your prescription. Page two is where you set yours, because a 95 kg man and a 60 kg woman do not eat the same lunch.

Step 2

Plan your three meals

Lunch at twelve. Dinner at six. Something at nine. Protein first on every plate, and the rest sorts itself out. Nothing before noon.

Step 3

Book your three sessions

Day A upper, Day B lower, Day C full body and lighter. Thirty minutes each. Put them in the calendar like meetings, because that is what they are.

Step 4

Track it for twelve weeks

One line a week. Weight, sessions done, how you slept. That is the whole log and it is deliberately boring.

John Swan

The book

You are not lazy. You are busy, and every plan you have tried was written for somebody with two spare hours and a chef.

So I cut things. Then I cut again. What is left is three numbers small enough to hold in your head on a bad Tuesday, which is the only test that ever mattered.

It is not magic. You still have to show up three times a week and put protein on the plate. But you stop spending energy on the decision, and the decision was most of the fight.

Twelve weeks later you look different. More to the point, you feel like someone who could do another twelve.

John Swan writes about training, food, and the habits that hold up when life gets loud. He publishes at johnswantech.substack.com.

Questions

The ones people actually ask

Probably not exactly, and that is the point of page two. Page one shows a worked example that happens to land near 1,600 a day. Your number comes out of your own bodyweight and activity. A 1,000 calorie deficit is an aggressive push, not a forever setting, which is why the method is three months and then maintain. If you have a health condition, are pregnant, or take medication, talk to your doctor before you change how you eat.

It is a scheduling trick more than a nutrition one. Most busy people are not hungry at seven, they are just awake, and pushing the first meal to noon buys you three real plates inside a window you can actually defend. If you train early or you feel wrecked without food, move the window. The three meals matter more than the clock.

That is all, and it only works because the thirty minutes are heavy and you log every set. Three honest sessions you actually do beats five ambitious ones you skip by week three. Day A pushes and pulls, Day B is lower body and core, Day C is full body and lighter.

You miss a week. It happens around week five for almost everybody. You do not restart, you do not make it up, you just do the next session. Twelve weeks with two ragged ones in the middle still ends somewhere completely different from where you started.

It is easier with one. A pair of adjustable dumbbells and a floor covers most of it, and the book has the swaps. The toolkit gives you the three day split either way.

It is out now on Amazon. The toolkit is still free either way, and it is the whole method on one page if you want to start before the book arrives.
