Sets, reps and progressive overload: what to write down

Every coach gets the same three questions, and they all arrive at once: how many sets, how many reps, how much rest. The honest answer is that the numbers matter less than whether the client can repeat them, and far less than whether they go up over time.

Reps set the goal

Rep ranges are a rough dial, not a law. Low reps with heavy loads bias toward strength; the middle range is where most hypertrophy work sits; high reps with short rest lean toward endurance and conditioning. The ranges overlap heavily, which is why an untrained client gets stronger and bigger on almost anything — the range starts to matter as they run out of beginner progress.

Sets set the dose

Sets are how much of that stimulus you give per week, and this is where most programs go wrong in one direction: too much, too early. A beginner does not need six sets per movement. Start at the lowest dose that produces progress, because you can only add. A program that opens at maximum has nowhere to go except down.

Rest is part of the prescription

Rest is the number coaches most often leave off the sheet, and the one clients most often get wrong. Heavy strength work needs long rests — the point is to recover enough to move the same weight again. Conditioning work needs the rest kept short, because the incomplete recovery is the stimulus. Writing a number down is what stops a client from inventing one.

Progressive overload is the actual program

A program that stays the same is not a program, it is a workout you repeated. Something has to increase over weeks, and it does not have to be the load: add a rep, add a set, shorten the rest, slow the eccentric, improve the range of motion. Pick one variable to move at a time so you can tell what worked.

• Add reps within the range first, then add load and drop back to the bottom of the range.
• Change one thing per cycle. Two changes at once means learning nothing from either.
• Plan an easier week roughly every fourth one. Progress that never lets up stops being progress.
• Write last cycle numbers where the client can see them, or they cannot beat them.

The common mistakes

Prescribing to failure on every set, so nothing is left to progress with. Changing the whole program monthly, so no movement is ever practised long enough to improve. Giving a beginner an advanced split because it looks serious. And writing sets and reps but no rest, no tempo and no note, then wondering why execution drifts.

Getting it onto the page

All of this only helps if it survives the trip to the client. Sets and reps belong on each movement, the pairing has to be visible when two exercises are meant to run back to back, and the cue that fixes execution should sit with the exercise rather than in a message that scrolls away. In fitlo those live on the exercise itself, so every program you write carries them without you retyping anything.
