When to add weight to the bar

The usual way people decide to add weight is that a set felt easy. You rack the bar, it did not hurt much, and next week you put another 2.5 kg on.

The trouble is that "felt easy" is not stable. It moves with sleep, caffeine, whether the gym was busy, whether you were in a good mood, and how recently you last did the lift. Two identical sets can feel different on two Mondays, so a decision built on that feeling produces different answers for the same performance.

There is a cleaner rule available, and its main virtue is that it is decided in advance.

The rule

Hit the top of your programmed rep range, and the weight goes up.

If your range on an exercise is 8 to 12, then the first time you get 12, you have earned the increase. If your range is 5 to 8, it is 8. The number was set before the session started, so reaching it is a fact rather than a judgement, and there is nothing to negotiate with yourself about afterwards.

The increase itself then counts as your progress for that exercise. You do not have to also beat something at the new weight for the session to have gone well. Moving up is the good outcome, and your first session at the new load simply starts a fresh baseline for what comes next.

The part people find strange: effort is irrelevant here

This surprises people, so it is worth stating flatly. When you hit the top of the range, how close to failure it was does not matter. Twelve reps with three left in the tank earns the increase exactly as much as twelve reps that nearly buried you.

That sounds inconsistent, because effort matters enormously elsewhere. At a fixed weight, effort is the whole game: 8 reps with 2 in reserve is a better session than 8 to failure, and any honest comparison has to account for it.

But the top of the range is not a comparison. It is a threshold, and thresholds work by being crossed. If you get 12 with three left, the weight was too light, which is precisely the situation adding weight is meant to fix. Making you re-earn it at a higher effort would mean punishing you for having got strong enough that the load stopped being challenging.

The two rules are doing different jobs. One decides whether the load should change. The other decides whether you improved while it stayed the same.

Adding weight without earning it

You are allowed to. Nothing enforces this, and there are decent reasons to jump early, including that you set your range too conservatively in the first place.

What you lose is the ability to say how it went. The old baseline was at the old weight, so it cannot be compared to anything at the new one. Until you have two sessions at the new load, there is nothing to measure the second against the first, and the honest verdict for that first session is no verdict at all.

That is not a punishment, it is just what the data supports. A tracker that produces a confident verdict there is making something up.

Weight going down

The mirror case matters as much and gets handled less well.

If the weight drops and you meant it to, that is not a regression. Deliberately backing off for a technique reset, or because you decided to take a lighter week, is a choice. It should clear the slate and start a fresh baseline, not sit in your history as a failure.

If the weight drops and you did not mean it to, that is a regression, and it should be recorded as one. The distinction is entirely about whether it was deliberate, which is something only you can say. That single flag is the difference between a log that reflects what happened and one that quietly accumulates fake failures every time you sensibly back off.

Which set has to hit the number

The first working set. Not your best set of the day, and not any set.

The reason is the same one that governs the rest of this: by the second set you are carrying fatigue from the first, and how much depends on how long you rested. The first working set is the only clean read on what you can do. Warm-ups are excluded entirely, because a warm-up was never an attempt at anything.

So if you get 10 on set one and 12 on set three, you have not hit the top of the range in the sense that matters. What you have is an interesting session, and possibly a sign your first set was under-prepared.

What this looks like in practice

Set a rep range on each exercise and write it down. Not a target rep count, a range, with a top you can actually reach.

Then the decision each session is mechanical. Did the first working set hit the top of the range? If yes, add weight next time and stop thinking about it. If no, keep the weight and try to beat your effective reps, which means either more reps at the same effort or the same reps with more left in the tank.

The value is not that this squeezes out more progress than intuition would. It is that it removes an argument you would otherwise have with yourself every week, and it gives every session a clear result: either you moved the load, or you moved the number at the load, or you did neither and that is worth knowing too.

Common questions

When should I increase the weight on an exercise?

When you hit the top of your programmed rep range. If your range is 8 to 12 and you get 12, the weight goes up next session, regardless of whether those 12 felt hard or easy.

Does it matter how many reps I had left in reserve?

Not for this decision. Reaching the top of the range is the condition, and effort deliberately does not enter into it. Effort matters for judging whether you progressed at a fixed weight, which is a different question.

How much weight should I add?

That is your call, and it depends on the lift and the smallest plates you have. The useful part is knowing that an increase is earned; picking the jump is a decision you are better placed to make than any rule.

What happens if I add weight before hitting the top of the range?

Nothing breaks, but you lose the ability to say whether it went well. There is no baseline at the new weight yet, so the honest answer is no verdict until you have two sessions at that load to compare with each other.

What if I hit the top of the range on my second set but not my first?

Then you have not hit it on the set that counts. Progress is judged on the first working set, because it is the only one not carrying fatigue from the sets before it.
