5x5 workout: five sets of five on a few big lifts, and what heavy fives build

A 5x5 workout is five sets of five reps on a few big lifts. The usual shape: three sessions a week, each built on two or three barbell lifts such as the squat, the bench press, the overhead press, the row and the deadlift, with the same weight for all five sets. When you complete all 25 reps, the weight goes up next time.

The appeal is that it's simple. Few exercises, one rep scheme, one rule for progress. Several published programs are built on it; this page covers the format itself, not any one of them: a sample routine, how to pick the weight and add to it, how long to rest, what the studies of heavy sets found, and who it suits.

A sample 5x5 routine

Two workouts, A and B, alternated across three days a week with a day off between, so one week is A, B, A and the next is B, A, B. Several published 5x5 programs use this same A/B layout; this table shows the format, not any one program's full rules.

The deadlift gets fewer sets because the squat already trains your legs and hips in every session. A short core block or a little arm work can go at the end. Warm-up sets with lighter weights come before the first work set of each lift and don't count toward the five. (How to warm up before lifting.)

How to pick the weight

Start lighter than you think. Pick a weight you can lift for all five sets of five with good form and a rep or two left at the end of the last set. (How to judge reps left.) For most people that's well below the heaviest weight they could lift for a single set of five.

Five reps is a heavy set. For intermediate and advanced lifters, the American College of Sports Medicine's 2009 stand recommends eventually emphasizing heavy sets of 1 to 6 reps for strength, with three to five minutes of rest between them. For novices, the same stand recommends loads of an 8 to 12 rep maximum, two or three days a week.¹ A beginner can still use the 5x5 format, though the trials below were all in trained men; start well short of a true five-rep max and climb from there.

How to add weight

• All 25 reps done with good form: add a little weight next session, the smallest jump your gym allows on presses and rows, a bit more on squats and deadlifts. The ACSM's 2009 rule: once you can do the current weight for one or two reps more than your target, add 2 to 10%.¹
• Missed reps: keep the weight and try again next time.
• Missed the same weight several sessions running: take the weight down about 10% and build back up, or take a deload week. Progressive overload covers stalls in more detail.
• Reps instead of weight also work. In an eight-week trial of 43 lifters, 27 men and 16 women with at least a year of lower-body training, adding reps at the same load and adding load at the same reps were both viable, with strength slightly favoring the load group by a margin of questionable practical size.²

How long to rest between sets

Longer than you would for lighter sets. A 2018 systematic review of 23 studies and 491 participants concluded that trained lifters seem to need more than two minutes to get the most strength, while one to two minutes appears to be enough for people new to lifting.³ On a 5x5, two to three minutes is a good default on the presses and rows, and three to five on the squat and the deadlift once the weights are heavy. (How long to rest between sets.)

Is 5x5 good for strength and muscle? What the studies found

No trial of a 5x5 program by that name turned up in a PubMed search for this page. Trials of heavy, low-rep training against moderate reps come close:

• Heavy fives against tens. In 29 resistance-trained men over eight weeks, one group did four sets of 3 to 5 reps at about 90% of their one-rep max with three-minute rests, and the other four sets of 10 to 12 at about 70% with one-minute rests. Bench press strength rose 14.8% in the heavy group against 6.9%, and lean mass in the arms 5.2% against 2.2%. The groups also differed in rest and total work.⁴
• Heavy against moderate, sets matched. In 19 resistance-trained men training three days a week for eight weeks, with three sets of seven exercises in both groups, sets of 2 to 4 reps built more squat strength than sets of 8 to 12, and sets of 8 to 12 built more thickness on the outer thigh.⁵
• Heavy against moderate, total work matched. In 17 well-trained young men over eight weeks, seven sets of three heavy reps and three sets of ten produced no significant difference in biceps thickness. Bench press strength favored the heavy group, and squat strength leaned the same way.⁶
• The review. A 2017 review of 21 studies found that light and heavy loads built similar muscle when sets were taken to failure, with heavy loads better for one-rep-max strength.⁷ The American College of Sports Medicine's 2026 position stand found strength was enhanced by heavier loads, by two to three sets, and by doing an exercise at the beginning of a session.⁸

Read together: sets of five sit in the heavy range these studies found better for one-rep-max strength. For muscle size the picture is mixed, with one trial favoring the heavy group, one the moderate group and one finding no difference, so heavy sets like a 5x5's are a strength-first choice that can also build muscle, not the only way to build it. The trials were short, eight weeks, small, and in trained men.

Who a 5x5 suits

• It suits someone who wants to get stronger on the big lifts, likes a simple plan, has a barbell and a rack, and can train three days a week.
• It suits less well someone whose main goal is muscle size in every muscle, since 5x5 has few exercises and no arm or shoulder isolation work. More exercises, including some isolation work, cover that better. (How many reps covers the trade.)
• Training at home with dumbbells works with the same format on goblet squats, dumbbell presses and rows, though progress by weight runs out sooner.

The common mistakes

• Starting too heavy. The format works because the weight climbs for weeks. Start with a weight you could do for more than five.
• Grinding reps with broken form. A rep that changes shape to get up isn't a rep to count.
• Short rests. Rest at least two minutes.
• Adding exercises until it isn't a 5x5. A little core or arm work at the end is fine; a second full workout on top isn't.
• Lifting through something that hurts. Hard sets are the point; a sharp or lasting hurt isn't. Stop, and see a doctor or a physical therapist.

If you'd rather not plan it alone

A 5x5 is simple on paper; picking the starting weights, deciding when a stall means rest and when it means a change, and fitting three sessions around your actual week is the part a page can't do. Coaching is the version where your workouts are built around the days you actually have, and a weekly call looks at the week you just had and rebuilds the next one. Coaching to get stronger explains how that works, and here's how to apply. Otherwise: pick weights you could lift eight times, do workout A this week, and write down every set.
