Twelve Weeks From Today

Today is the 30th of September. Twelve weeks from today is the 23rd of December. Twelve weeks is long enough for the following to happen.

Weeks 1 to 6. You get stronger without looking any different. The early gains are neural — your nervous system learns to recruit more motor units, more quickly, better coordinated. This is why a beginner can add 20kg to a deadlift in six weeks and their trousers fit exactly the same. It is strength, and it's the fastest progress you will ever make.

Weeks 6 to 10. The engine moves. Aerobic capacity responds to hard work within about eight weeks, and it shows up in ordinary places first — Amersham Hill, the stairs at the station, carrying a child upstairs without noting it. Resting heart rate usually drops a few beats.

Weeks 8 to 12. Muscle starts to arrive, provided protein is somewhere between 1.6 and 2.2 grams per kilo of bodyweight. Not much of it. A kilo or two, which changes how clothes sit long before it changes what the scales say. The scales are the worst instrument for this.

What the first fortnight is like: you'll be sore, particularly after the first two or three sessions, and you'll spend more time learning movements than getting out of breath. It settles inside three weeks. Almost everyone who quits does it in that window. Please, please don't be one of them — three weeks is nothing.

Twelve weeks of two or three sessions gets you all three. Nothing dramatic — a stronger, fitter version of you, in time for a fortnight of eating and drinking that you'll handle considerably better than last year.

Two things have to hold across the twelve weeks. Protein at 1.6–2.2 grams per kilo, most days, which is the one nutritional variable that matters here. And two sessions a week, in the same two slots, which is the one training variable. Everything else is detail.

The first step is a fifteen-minute phone call. Then Ignite: classes from your first week, with five one-to-one hours running alongside them, covering the movements and testing five benchmarks we'll retest across the following year.

Nobody is ever ready. Twelve weeks is going to pass regardless of what you do with it.

Don't wait until after the Christmas break, habits formed now are much easier to keep.
