Linear Progression: Adding Weight Every Session

What linear progression is

Add a small amount of weight to the bar every session. Keep the sets and reps the same. Repeat until you cannot.

That is the whole method. Three sets of five at 60 kg on Monday, 62.5 kg on Wednesday, 65 kg on Friday. No percentages, no planned light weeks, no auto-regulation. The only decision is what to do when you miss.

It works for beginners for a specific reason: a new lifter's performance improves faster than their muscle does, mostly through learning the movement and getting better at recruiting the muscle they already have. Measured muscle size barely moves in the first few weeks, and what does move is partly swelling rather than new tissue (Damas et al., European Journal of Applied Physiology, 2016). That gap is generous enough that the bar can go up every single session for a while. It does not last, and that is not a failure of the method.

The increments that actually work

The smaller the better, and smaller than most people start with.

If your gym has 1.25 kg plates, buy into them early. On the overhead press the difference between adding 1 kg and adding 2.5 kg is weeks of extra progression. How much weight to add covers increments in more detail, including what to do when the smallest jump available is still too big.

Do not scale increments to how easy the set felt. The whole point is that the jump is small enough to survive a mediocre day.

How long it lasts

Weeks to months, and it varies by lift. Upper body runs out first because the muscles are smaller and the same absolute jump is a bigger relative one. Two and a half kilos on a 60 kg squat is 4 percent. The same 2.5 kg on a 30 kg overhead press is 8 percent.

The usual pattern is that overhead press stalls first, then bench, then rows, then squat, then deadlift. When one lift stops, the others usually keep going. Do not end the whole programme because one lift ran out.

If you started with a training background, or you are returning after a break, expect it to move faster and end sooner.

The first time you miss

You will have a session where you do not get the reps. What you do next matters more than anything else in this article, because this is where most beginner programmes fall apart.

Do not immediately conclude it is over. A single missed session is usually sleep, food, timing, or a bad day rather than a genuine ceiling.

The sequence that works:

1. Repeat the weight next session. Same load, try again. Most misses clear on the second attempt.
2. Miss it twice? Repeat once more. Three attempts at a weight is not stubbornness, it is a reasonable sample.
3. Miss it three times? Reduce by about 10 percent and climb back. This is a reset, not a defeat. You will pass the old number in two or three weeks and usually go past it.
4. Reset twice on the same lift? That lift is done with linear progression. Move it to something slower.

The mistake to avoid is grinding the same weight for three weeks hoping it resolves. It is also worth checking the ordinary causes before resetting: are you eating enough, sleeping enough, and recovering? Those explain more stalls than programming does. Why your lifts stopped progressing works through them in order.

What comes after

When adding weight every session stops working, the next step is to add weight less often and earn it with reps in between.

That is double progression: pick a rep range, add reps within it until you hit the top of the range on all sets, then add weight and start again at the bottom. Progress moves from every session to every couple of weeks, which sounds worse and is simply what progress looks like once the beginner window closes.

You do not need to switch everything at once. Move each lift when that lift stalls, and let the others keep running linearly.

What not to add while it is working

Linear progression is boring and effective, and the temptation is to improve it. Resist for the first few months.

Do not add exercises to fix a stall. More lifts means more fatigue and no more progression on the one that stalled.

Do not deload preemptively. A deload week is worth taking when fatigue is genuinely accumulating, which for a beginner doing three sets of five is not usually the situation.

Do not switch programmes because progress feels slow. Two and a half kilos a session, three sessions a week, is 30 kg a month at the start. Nothing feels slower and works faster.

Do not chase soreness. It tracks unfamiliarity, not growth. How muscle growth actually works covers why.

Keeping the count

Linear progression is trivially simple and depends entirely on knowing what you did last time, on every lift, without guessing. That is the one thing paper is bad at mid-session.

Lift, which publishes this page, shows last session's weight and reps on the set you are about to start, which is the whole requirement here. Log the set and next time the previous numbers are waiting. If you want the arithmetic handled too, Premium auto-progression can raise the target for you when you hit your reps, per exercise, so a lift that is still progressing linearly and one that has moved to double progression can run different rules in the same session. The progressive overload calculator shows the same idea in the browser without installing anything.

Logging and previous performance are free. See how Lift handles progression, or read the complete guide to progressive overload for the wider picture.

The most valuable thing about this method is that it expires. When it does, you have several months of data and a clear reason to change something.
