Progressive overload: what it is, linear vs double progression, and how to break a plateau

Four levers of progression

Progressive overload is the gradual increase of training demands, most often load, reps or sets (the 2026 ACSM position stand). In the gym you have four levers; the last two rows show how much strength grows and when to call it a plateau.

When you need progression and how fast the weight goes up

Your first weeks of training bring results even without progression. Further progress requires training to get harder over time (the 2026 ACSM position stand), but that doesn't have to mean more weight every week: an extra rep at the same weight is progression too.

The rep ranges page covers how to choose the range itself, and the progression section of the knowledge base lists every topic. How fast estimated 1RM grows at each level is in the data box below, and the strength standards show where you stand compared with other lifters.

How to plan progression step by step

1. Give each exercise a rep range and a target RIR, e.g. 6-10 on the barbell squat and 8-12 on the dumbbell bench press at RIR 2, 12-20 on dumbbell lateral raises at RIR 1-2; in your first weeks of training, RIR 2-3.
2. Choose the method: double progression with a rep range, linear progression with fixed reps on barbell exercises, e.g. 3 × 5 on the squat.
3. Pick a starting weight that gets you to the bottom of the range with one more rep in reserve than the target, e.g. 8 reps at RIR 3 for a target of 8-12 at RIR 2; the RIR/RPE calculator works it out.
4. Log every working set (weight, reps and RIR), and next session add a rep to it or, at the top of the range, the smallest weight step.
5. Every 4 weeks, compare the estimated 1RM of your main exercises with the figure from a month earlier.
6. When one exercise stalls for 2 sessions in a row (3-4 after your first year), go through the plateau checklist below.

Always log dumbbell weight the same way, ideally per dumbbell, because logging the weight of one dumbbell one time and of both the next breaks the comparison with your last workout.

The guide how to progress in a plan shows how these rules work in our 8-week plans, from the calibration week to a plateau.

Linear progression in the gym

Linear progression means adding a fixed weight step every session at the same sets and reps, such as 2.5 kg on a 3 × 5 squat. The rule has three points:

1. If you complete all sets and reps through the full range of motion, with at least 1 rep left in reserve on the last set, add 2.5 kg next session, or even 5 kg on the deadlift at the start, because the 2009 ACSM position stand advises a larger percentage for exercises that train large muscle groups.
2. If a set falls short, or the last rep is at the edge of failure, stay at that weight.
3. After a third failed session in a row, take off about 10% and work back up in 2.5 kg steps.

Example: you start the barbell squat at 3 × 5 with 40 kg and 3-4 reps left in reserve, and squat twice a week; by the 8th session, after 4 weeks, you're at 57.5 kg. The first weeks mostly get you to a weight you can already lift; after that, each 2.5 kg step gets harder.

A 2.5 kg step is 2.5% of a 100 kg squat but already 5% of a 50 kg bench press, which is why the bench press and rows stall sooner than the squat and deadlift. When the weight stalls at the same point again after the 10% reset, move to a rep range and double progression, or, with a strength goal, to linear periodization or a top set with back-off sets.

Linear progression is not linear periodization. Progression is what you do with the weight from session to session; linear periodization is a plan over weeks and phases in which the reps go down while the load goes up (2009 ACSM position stand).

Double progression: reps first, then weight

Double progression is a rep-range method, e.g. 3 × 8-12 at RIR 2: you add reps at the same weight, and once all sets reach the top of the range, you increase the weight and drop back toward the bottom.

• As long as you finish a set with the reserve from your plan, add one rep to it next session.
• Once all working sets reach the top of the range at your target RIR, add the smallest weight step next session.
• If you have 2 more reps in reserve than the target at the top of the range, the step can be bigger, e.g. 5 kg on a barbell; the RIR/RPE calculator works out the weight for your target RIR.

This is a faster version of the 2-10% rule from the 2009 ACSM position stand: instead of two sessions with 1-2 reps over the target, one session at the top of the range at your target RIR is enough, because the logged reserve tells you the same thing as the extra reps would. Beginners in a 6-10 range add weight almost every week anyway, so at the start double progression looks like linear progression.

The last set usually lags behind, and the weight goes up once it catches up with the first ones. In the set-by-set variant (often called dynamic double progression), the first set moves to 22 kg when it reaches 12 reps, while the others stay at 20 kg until they get there too; this softens the big jump on dumbbells.

For five weeks the weight stays put while estimated 1RM rises from 25 to 27 kg (the average of the formulas in the 1RM calculator). A set of 22 kg × 9 gives an estimated 1RM of about 28 kg, so the weight change only records strength you already built with reps. That's why you measure progress with estimated 1RM, comparing sets in a similar rep range.

In an 8-week study of trained lifters, those who added reps built about as much muscle as those who added load; strength rose slightly more with added load (Plotkin et al. 2022). In untrained people, both approaches increased strength and muscle mass over 10 weeks (Chaves et al. 2024).

The smallest weight step on barbells, dumbbells, machines and the pull-up bar

The smallest weight step depends on the equipment, and its size as a percentage decides whether linear progression is enough for an exercise or whether you need a rep range.

Linear vs double progression vs periodization

The table compares linear and double progression with linear periodization.

For muscle, periodization gives no advantage over a non-periodized program with the same number of sets, and for strength in trained lifters it gives a small one (Moesgaard et al. 2022).

What to check when you hit a plateau in the gym

A plateau (stagnation) is when you stop making progress despite training regularly. In a single exercise, a plateau is two sessions in a row at the same weight, with no added reps and no easier RIR. That's how you count it in your first year of training; after that, reps come less often than every session, so judge an exercise plateau over 3-4 sessions or 2-3 weeks.

First work out whether one exercise has stalled or most of them. For one, go through the list from the top; for most, start with sleep, food and fatigue.

When one exercise is stuck and the list turns up nothing, after the next session without progress take off about 10% of the weight and rebuild the reps; if it stalls at the same point again, change the range or the exercise in your next cycle.

Common mistakes

1. More weight every week on every exercise. On dumbbells and isolation exercises, one step is often more than your reps can make up for, so sets fall below the range. Add reps first.
2. Reps at the cost of form or reserve. A shallower squat, a faster lowering phase or swinging your torso on curls adds a rep only on paper, and so does a rep at RIR 0 instead of the planned RIR 2. Count reps through the full range of motion, at the tempo from your plan and at your target RIR.
3. Adding set after set. Each extra set gives less, and in strength the diminishing returns are even clearer (Pelland et al. 2025). As long as a muscle group's sets are within its target and the weights or reps are going up, don't add sets.
4. A new plan every week. When exercises change every session, you have nothing to compare your result with, and frequent random changes may slow gains (Kassiano et al. 2022). Keep your plan for the whole cycle, e.g. 8 weeks.
5. Old weights after a break. After a week or two off, the first session at your old weight usually feels harder than the plan intends. Do it about 5-10% lighter and return to the old weight within 1-2 sessions.
6. A result from a different machine. The same number on the stacks of two machines is a different resistance, and on the same machine a different seat setting changes your reps. Log the setting, and after switching gyms start that exercise's progression from scratch.

What the research says

Research on progression asks whether you need to add weight, how fast strength grows and whether periodization protects against plateaus.

It's unknown which progression method works best for advanced lifters over more than a few months: the comparisons of load and reps lasted less than three months and covered only the legs.

What SmartWorkout logs show

Most sessions repeat the previous weight, and when it does go up, the jumps are large: usually 14% on dumbbells and 5 kg on a barbell, which is two of the smallest steps. For beginners on the squat, starting from an estimated 1RM of about 67 kg, 15% is about 10 kg in six months, or just under half a kilogram a week on average. If a jump drops you below your range, add 2.5 kg at a time on a barbell, and on dumbbells add reps first. Every number is based on at least 50 people.

How to track progression in SmartWorkout

You track progression in SmartWorkout from your log: next to every set you see your previous result, estimated 1RM and the rep range from your plan.

1. Open “Workout Settings” (the settings icon on the workout screen) and under “Effort scale” choose the “Scale type”: RIR or RPE.
2. In the plan creator (Workout > My Plans > “+” > “Create new plan”), choose RIR as the “Load Indicator”, and for each set enter a rep range, e.g. 8-12, and a target RIR.
3. After every working set, log the weight, reps and RIR, and next session compare them with the previous result next to the set.
4. Every few weeks, check on the exercise chart that your estimated 1RM is going up.

With Premium, you know what to do at your next workout: add a rep, add weight or stay at your current target. With a rep range, the suggestions run double progression for you and match the weight step to your equipment, and with logged RIR they are more accurate. The help article on progression suggestions explains how they work.
