Why week one is a calibration week

Week one of most programs in this catalogue prints weights that look light. They are light. Week one has a different job from the weeks that follow it.

The job

The programs prescribe effort in reps in reserve, the number of reps left in you when a set ends. A target of two in reserve means nothing until you know which load produces it for you, and a chart of someone else's numbers cannot tell you that.

Week one finds that load. You work up on each main lift and stop at the target effort. Write down what the bar held.

The weeks after it run on those numbers. The page keeps setting the sets, the reps, the rest and the effort; you carry your own weights forward against those targets, which is a far better instruction than a figure printed for a stranger.

How to calibrate a lift

Start with an empty bar or a light dumbbell. Do a set of 8 reps. Assess how hard that felt relative to the effort target printed on the page. If the target says two reps in reserve and the set felt like you had six reps left, the weight is too light.

Add weight. Do a set of 5 reps. Assess again. If you had four reps left, the weight is still too light but getting closer.

Add weight again. Do a set of 3 reps. If the set reaches the effort target, with about two reps left in you when you stop, the weight on the bar at that point is your working weight for week one. Write it down.

The process takes three to five sets per exercise and adds about two minutes to each movement compared with jumping straight to a working weight. That investment pays for itself across the next eleven weeks, because every subsequent session runs on a number you found rather than a number you guessed.

For exercises that use machines or cables, the same approach applies. Start with a light pin setting, work up in small jumps, and stop at the effort target. Cable stacks move in fixed increments, so the jumps are predetermined. A few sets of climbing is all it takes.

Write the numbers down during the session, not after. A working weight remembered in the car park is less reliable than one written on the page between sets. The logbook is part of the calibration process.

Starting light

Run the comparison. One lifter treats week one as a test, grinds out maxes on day one and walks away with numbers for the fridge door. He spends the next fortnight sore, missing reps at loads that should move.

Another lifter logs a week of sets that stop two reps short of their limit, then adds load for eleven weeks without a stall. Around week five she passes the max tester, and she is still climbing when he starts over.

Testing tells you what you can lift once. Calibrating tells you where to start for the next eleven weeks, which is the more useful number by a distance.

What if you start too heavy

A common concern is choosing a working weight that turns out to be too high. Week one, day one, you load the bar at what you think is a two-reps-in-reserve weight, and the set goes to failure. That session is not wasted. It is data.

The second session of the week corrects it. Drop 5 to 10 per cent from the weight that was too heavy, and run the session as written. If the program calls for three sessions in week one, you have two remaining sessions to find the right number. A heavy first session is one day of recalibration. It is not a wasted week.

The same applies if the weight was too light. If the set felt easy and you had five or six reps in reserve instead of two, add 5 to 10 per cent for the next session. The direction of the error does not matter. What matters is that you adjust before week two starts, because week two builds on whatever number week one established.

Err on the side of starting lighter rather than heavier. A weight that is 5 per cent too light on week one becomes correct by week three as the program adds load. A weight that is 5 per cent too heavy on week one produces failed reps by week three, which means a reset and lost time.

Calibration for experienced lifters

If you have been training for several years and you know your working weights, week one still has a purpose. It confirms those weights rather than discovers them.

A break between programs, even a short one, changes things. Two weeks off for a holiday, a week of illness, or a transition from one program to another all affect readiness. The weights you used in week twelve of your last program may not be the right starting weights for week one of the next one.

Use week one to verify. Load your expected working weight, perform the prescribed reps, and check the effort level. If the set hits the target, the weight is confirmed and you move forward. If the set felt harder than the target, drop 5 per cent and use that as your week one number. The program will bring you back to your previous weights within a few weeks, and the path there will be smoother.

Experienced lifters sometimes skip calibration because the weights feel too light and the session feels unproductive. The session is productive. It establishes the baseline that the subsequent weeks build on, and it gives the tendons and connective tissue a low-stress re-introduction to the loading pattern. A careful first week prevents the nagging joint discomfort that often appears in week three or four when a trainee jumps straight to heavy loads after time away.

If you are switching from a program that used different rep ranges, week one also recalibrates the load for the new range. A set of five at 100 kg does not predict a set of ten at 75 kg with any precision, because fatigue, technique, and mental tolerance all shift with the rep count. Calibrating in the new rep range gives you a number that belongs to that range, not a conversion from an old one.

Bands and bodyweight

A barbell makes calibration quick, because the load is a number printed on the plate. A band resists more the further you stretch it, so the dose depends on which band you pick and how far from the anchor you stand.

Tension, the bands program, runs two calibration weeks for that reason. The bodyweight program does the same, because finding the right version of a push-up takes longer than finding the right dumbbell. Two weeks of finding the dose beats six weeks of the wrong one.

The retest

Some programs close with the measurement they opened with. The final week retests what calibration found, at the loads you built in between, and the difference between the two numbers is what the program did.

The light week is the design. It finds the numbers the other eleven weeks run on.
