The short answer
If the program ended with a deload, start the next block on Monday from the loads you lifted in the last full week before it. If it did not, take one light week first. Then do one of three things: run the program again from the new loads, change one variable, or train a different goal for a block. Do not test a one-rep max, and do not start the hardest program you can find.
This is for someone who finished last week, is pleased, and has a browser tab open on a six-day split.
Why not jump to the hardest program you can find
Because the program you just finished is not what is holding you back, and the harder one does not know you. Twelve weeks of steady steps worked because each week’s load came from the week before. A new program starts from a guess, usually a percentage of a max you do not have, and spends its first weeks finding out what you could already have told it.
The position stand on progression models says what comes after the novice stage: planned variation, the program changing in blocks so that load, reps and volume are not all climbing at once (Ratamess et al., 2009, Medicine & Science in Sports & Exercise). More of everything at once is the opposite of that. The six-day split in your other tab is one of those blocks, several blocks from now.
Do you need a week off first
No. You may need a light week. Both halves of that have been studied.
A 2023 Delphi study asked experienced strength and physique coaches to agree, over three rounds, on what a deload is. Their definition: a period of reduced training stress designed to reduce physiological and psychological fatigue, aid recovery, and improve readiness for the training that follows (Bell et al., 2023, Sports Medicine – Open). Reduced. The coaches placed it exactly where you are now, between blocks.
The alternative has a cost. In a 2024 trial, trained lifters followed nine weeks of supervised training; half of them took a complete week off in the middle. At the end, the group that rested had lost ground on lower-body strength compared with the group that kept training, while muscle growth was the same (Coleman et al., 2024, PeerJ). A week with no training is a week in which the lifts were not practiced, and strength is partly practice.
So: one week, and what goes in it depends on how your program ended.
- It ended in a deload. You have already had the light week. Start the next block on Monday.
- It ended on a heavy week. Take one week with 10 to 20 percent off your last loads and the sets halved, never below two, on the same lifts and the same days. That is the shape the coaches in the Bell consensus agreed on: volume down, load down a little, lifts and days unchanged. Then start the next block.
What a light week looks like set by set is in when to deload.
The three options
Run it again from the new loads
Nothing about the program wore out. What changed over 12 weeks is you: every lift has a number against it that is higher than it was, and the rule that moved those numbers works just as well on the new ones. Running the same block again is the option with the fewest unknowns and, after a first block, usually the one that returns the most for the least thought. If a lift was still moving in week 11 and the schedule has not changed, I would do this and close the other tab.
Skip the learning week. You know the lifts. Start where the heavy weeks left you and let the rule decide the first step.
Change one variable
When the steps stopped arriving on more than one lift in the last block, or when the week itself has changed, change one thing. One, so that when the next block goes well or badly you know why.
The usual candidates, in the order I would reach for them. There is no trial behind this order; nobody has randomised beginners to a second run against a changed variation, so it is practice, not proof.
- Days per week. From three to four if you have the time. The ACSM position stand puts intermediates at three to four days a week (Ratamess et al., 2009). Four days lets each session be shorter, or lets one lift get a third exposure.
- The main lift’s variation. Back squat to front squat, bench press to incline, conventional deadlift to Romanian. The pattern stays, and the stalled lift gets a rest without leaving the program.
- The rep range of the main lift. If the last block ended at 5–8, a block at 8–12 on the main lift is lighter and often lets the loads climb again afterwards.
Train a different goal for a block
Twelve weeks of strength can be followed by twelve weeks of something else: more volume at higher reps for size, or a block that keeps the three main lifts and adds conditioning. The lifts and the loads come with you; the emphasis changes.
Which option fits you
| Option | Who it suits | Who it does not |
|---|---|---|
| Run it again from the new loads | Loads still climbing in weeks 9–11; schedule unchanged; a first or second block | Steps stopped on two or more lifts; bored to the point of quitting |
| Change one variable | A lift stalled for three weeks; a new day became free; the same lifts for 24 weeks | Everything was still moving; the urge is for novelty, not a fix |
| Train a different goal for a block | Strength is fine and the goal has changed; heavy sets have lost their appeal | The last block felt easy and you are still a beginner at the lifts |
Pick from the top row down. Most people after a first 12 weeks belong in the first row and feel they belong in the third.
How to set the new starting weights
Use the loads you finished on. If the program ended with a deload, that means the last full week before it, not the deload week. If there was no deload and you took a light week, it means the last week you trained before the light one.
Here is the arithmetic for a squat that ended at four sets of eight at 45 kg (99 lb) in week 11, with a lighter week 12:
| Load | Why | |
|---|---|---|
| Week 11, last heavy week | 45 kg for 4 × 8 | The number that was earned |
| Week 12, deload | 10 to 20 percent off, rounded to the plates, for 2 × 6 | Not a working weight |
| Next block, week 1 | 45 kg for 4 × 8 | Start where you finished |
| Next block, first step | One plate on | When every set hits the top of the range in two sessions |
No one-rep max test. A max tells you what you can lift once, on one day, with adrenaline and usually with someone filming; the next block is built on sets of five to twelve on ordinary Tuesdays, and you already have those numbers. Testing also spends the freshness the light week bought. If a new program insists on percentages of a max, the next-week load calculator shows what a week at the top of the rep range, a week short of it or a break does to a working weight, which is the question you actually need answered.
One case where the starting load is lower: if the new block changes the main lift’s variation, the first week on the new lift is a finding week, from the bar, the same as week 2 of the program you just finished. Front squat does not start at your back squat number.
What to keep
The three lifts you were progressing. A squat, a hinge and a press with 12 weeks of clean numbers behind them are worth more than anything else you own in the gym, and the common mistake at this point is to trade them for twelve new exercises and twelve new guesses. Change the variation if you must. Keep the pattern, and keep the log, whether it is an app or the back page of a notebook. Whatever the next block looks like, those three lifts should be in it, with the loads continuous from one block to the next.
Keep the weekly rule too. The step after a week where every set hit the top of its range, the hold after a week that did not, the light week after a break: none of that belongs to the first 12 weeks in particular. The program this page follows on from spells the rule out, and it does not change for a second block or a tenth.
What BurnX does
In the app, the last week of every block is the lighter week, so a block ends on it. A block summary shows what each lift did over the 12 weeks, and a one-minute check-in asks about your goal, your days and your equipment for the next one. The next block starts from the loads you finished on, and the weights keep moving the same way: up when you did the work last week, a hold when you did not, under a hard ceiling. How BurnX decides next week’s weights has the rest.
