Progressive overload for women: what it is and how to do it

Progressive overload means making a lift a little harder over time, with more weight, reps or sets, so your muscles keep adapting. The American College of Sports Medicine (ACSM) suggested in 2009 adding 2 to 10% to the weight once you can do one or two reps past your target. Women's relative gains in muscle and lower-body strength are similar to men's, so you progress the same way.

What is progressive overload?

The ACSM's 2026 position stand, an overview of 137 systematic reviews covering more than 30,000 people, defines progressive overload as "the need to increase the stimulus (stressor) placed upon the muscle throughout a training program." It recommends progressive resistance training for healthy adults to improve muscle function, size and physical performance, and it is less rigid about exact numbers than the 2009 guideline was.

Squat 40 kg (88 lb) for 3 sets of 10 every week for a year and your body settles in at 40 kg for 3 sets of 10. Ask a bit more of it and it has to adapt again. The weight can also climb while the effort stays put: as you get stronger, the same hard-but-doable set moves a heavier bar, and the paper counts that as progression too.

How to apply progressive overload: weight, reps or sets

Most of the time you'll add weight or reps. Adding a set is the biggest step of the three, so it's the one to save for when the other two have stopped working.

Progressive overload without adding weight

In one trial, adding reps worked about as well as adding weight. In the 2022 PeerJ study, 43 trained adults (16 of them women) progressed either by weight or by reps for 8 weeks, and the authors called both "viable strategies for enhancing muscular adaptations." Strength slightly favored the weight group, by about 2.0 kg on average, but the confidence interval ran from −2.4 to 7.8 kg, so that edge may not be real. Growth in one thigh muscle slightly favored the reps group. The authors judged the differences of "questionable practical significance." So if the next dumbbell up is a big jump, two more reps a set is real progress.

Going from 2 sets to 3 means 50% more sets on that exercise, so add one set at a time. Two sets beat one in the reviews behind the 2026 position stand, and strength gains were bigger with heavier weights (80% of your one-rep max or more), a full range of motion and 2 to 3 sets.

How much weight should you add?

On a 40 kg (88 lb) squat, the 2009 range of 2 to 10% means 0.8 to 4 kg, or about 2 to 9 lb. On a 20 kg (44 lb) dumbbell row it means 0.4 to 2 kg, about 1 to 4 lb. Add it when your reps say you're ready, whether that takes one session or five.

In practice, your gym's plates decide the size of the step. Plates go on in pairs, so the smallest step on a barbell is twice your smallest plate. With 2.5 lb plates that's 5 lb (about 2.3 kg): under 6% of an 88 lb squat, but 11% of an overhead press on an empty 20 kg (45 lb) Olympic bar. If the smallest plates on the rack are 5 lb, the step becomes 10 lb (about 4.5 kg), or 22% of that press. On a lift like that, stay at the weight and keep adding reps well past your usual target before you take the jump.

Progressive overload with dumbbells

Say you train at home with one pair of 8 kg (about 18 lb) dumbbells, and the next pair you can get is 10 kg (22 lb). That's 25% heavier, so at home, reps do most of the work. Use a wide rep range such as 8 to 15 and stay with your pair until every set reaches 15; then move to the next pair up and start again at 8. Before you buy heavier dumbbells, you can also add a set or switch to a harder version of the exercise, for example from a goblet squat to a split squat. Bodyweight moves work the same way: when push-ups with your hands on a bench get easy, put your hands on the floor.

A progressive overload example from the STRONG app

This is how STRONG plans it: the app picks your next weight using these rules.

STRONG uses double progression. Each exercise has a rep range. When every working set reaches the top of that range and your effort rating (RPE) is 8 or less, the weight goes up by one step next time: 1 kg (about 2.2 lb) on upper-body lifts and 2.5 kg (about 5.5 lb) on lower-body lifts, or the smallest step your equipment allows. Anywhere inside the range, the weight stays put while your reps climb. Your goal can raise the range: pick Build muscle and main lifts move up to 8 to 12 reps. Warm-up sets never count.

Say you're doing 3 sets of 8 to 12 at 20 kg (44 lb). Three sessions could look like this:

If you skip the effort rating, the weight won't go up: only a rated session can raise it. On a new exercise, the step can double in the first two sessions if they felt easy (RPE 7 or less), so you reach a realistic working weight sooner. An exercise you've never done starts from your related lifts: if you've logged back squats, your first front squat is estimated from them, a little on the light side.

The default program also runs in repeating blocks: a base week, two build weeks, a peak week and a deload week (the app calls it an easy week), and the last week is a test week. In the two build weeks, the main lift of each session gets one extra set.

What to do when you plateau

Some days the bar feels heavier than last week and you miss reps you hit before. STRONG handles that in two ways. If any set ends 2 or more reps below the bottom of your range, or below the bottom when you rate the effort Very hard (RPE 9.5), the next session's weight drops about 5%, so a 20 kg press goes to 19 kg. If two sessions in a row at the same weight both end below the range, the weight drops about 10%, from a 50 kg (110 lb) squat to 45 kg (99 lb), and you build back up from there. A stall inside the range doesn't lower anything: you keep the weight and keep working on the reps.

If you log your workouts on paper, you can borrow those numbers: take 5 to 10% off and climb back through the rep range to the old weight. These are our product rules, not research findings, but they give a stuck weight a way forward. When several lifts stall at once, an easier week may be worth trying, and the deload week guide explains how coaches run one.

A stall is different from pain. The ACSM's advice is written for healthy adults, so if a lift starts to hurt, stop that exercise and see a doctor or physical therapist before you load it again.

Do women gain strength like men?

Relative to where they start, women gain about as much as men. A 2020 meta-analysis in the Journal of Strength and Conditioning Research found that men and women adapted to resistance training with similar effect sizes for muscle growth and lower-body strength, based on 10 studies for muscle growth and 23 for lower-body strength. Women showed larger relative gains in upper-body strength, though the authors point out that most participants were untrained and the studies were short. So the method is the same; what differs is where you start and how big a step your current weight allows.

Your cycle doesn't change the rules either. A 2023 umbrella review found "scant low-quality and largely inconsistent evidence of marked differences" between cycle phases in strength, performance and muscle growth, and the cycle syncing guide goes through that evidence. For days when tiredness or cramps make a session harder, see working out when you're tired before your period and working out on your period.
