30-day glute challenge: three short glute sessions a week, at home or in the gym

Three 20-minute glute sessions a week, alternating a bridge, split squat and side-hip session with a hinge, step-up and band session, with rest days between. Every move has a ladder from home steps to gym options, and a single-leg bridge test on day 1 and day 30 shows the change. Your glutes can get stronger in a month; visible growth takes months, and no plan can promise a shape.

How the weeks progress

Week 1
Test, then learn the moves

Day 1: the single-leg bridge and chair stand tests, then find your step in each block: the hardest you can do for the bottom of its rep range with 3 or 4 reps to spare. Do 2 sets of the first two blocks and 1 set of the third. Session A: glute bridges with a 1 to 2-second pause (10 to 15), split squats (8 to 12 each leg) and side-lying leg raises (12 to 15 each side), or your steps. Session B: hip-hinge practice (10) or single-leg Romanian deadlifts with your fingertips on a wall (8 to 10 each leg), low step-ups (10 to 12 each leg) and glute kickbacks (12 to 15 each side). That's about 15 hard glute sets this week.

Week 2
Add sets, then reps

This week runs B, A, B. Do 3 sets of the first block and 2 of the others, stopping 1 to 3 reps short; the last set of side-hip work can end 0 to 2 short. Add reps up to the top of each range. That's about 20 hard glute sets a week.

Week 3
Harder, not just more

When every set of a move reaches the top of its range for 2 sessions, lower for 3 seconds for a session, then move up a step and go back to the bottom of its range: two-leg to staggered to single-leg bridges, then banded or loaded bridges or the hip thrust; split squats to reverse lunges to Bulgarian split squats; hinge practice to single-leg and then dumbbell Romanian deadlifts; a low step to a knee-height step, then holding dumbbells; leg raises to band walks to side planks with a leg lift, or the abduction machine.

Week 4
Settle, then retest

This week runs B, A, B again: the same sets at your new steps, building reps. Friday is the last session. Rest on day 29, then repeat the single-leg bridge and chair stand tests on day 30 the same way.

After 30 days
Keep it, then choose

Keep 2 glute sessions a week at your new steps, or move on: the 8-week glute workout plan in the gym, the glute workout at home, or, for the whole body, the 3-day home workout plan.

How to run it

The day 1 and day 30 tests

Single-leg glute bridge: lie on your back with one foot flat and the other knee held to your chest, and count steady reps, about 2 seconds up and 2 down, on each side until your hips drop or your pelvis tips. Then do the 30-second chair stand test as our test page describes, with your arms crossed and a firm chair against a wall. Repeat both on day 30, the same way.

A UK postnatal return-to-running guideline (Goom 2019) counts single-leg bridges to fatigue as a strength check and suggests aiming for 20 each side. That target is expert opinion from one guideline, not a norm, and the guideline says a lower count shouldn't hold you back, only show where to direct strength work. If you've had a baby, start with our postpartum and pelvic floor guides.

Finding and moving up your stepsEmerging evidence

In each block, train at the hardest step you can do for the bottom of its rep range with 3 or 4 reps to spare in week 1. When every set reaches the top of its range for 2 sessions, lower for 3 seconds for a session, then move up a step and go back to the bottom of its range; on a loaded step, add the smallest weight you have instead. The ladders and these rules are our editorial starting points, built on our glute and bridge guides.

Slower lowering and one-leg moves are fair ways to make a home step harder: reps lasting 0.5 to 8 seconds built similar muscle when the sets were hard (8 studies), and one-leg and two-leg training built similar muscle (9 studies). Adding reps and adding weight built similar muscle and strength in a trial of 43 trained adults, and the American College of Sports Medicine advises adding 2 to 10% once you can do 1 or 2 reps more than your target.

Sources 2, 3, 4, 5

How hard each set should feelStrong evidence

End most sets 1 to 3 reps short, and 3 or 4 short in week 1 while you learn the moves; the last set of side-hip work can end 0 to 2 short. Most people misjudge how many reps they have left by about one, so stop when a rep slows or your form changes.

Light loads and bodyweight build muscle only when the sets are hard: light, moderate and heavy loads built similar muscle when the sets were taken to failure (28 studies), so keep light sets hard and move up a step rather than going past about 20 reps. You don't need to reach failure itself: the American College of Sports Medicine found it isn't necessary, and a review of 15 studies found no clear growth advantage from it.

Sources 6, 7, 8, 9

Three sessions a week, not every day

Sessions A and B alternate: A, B, A in weeks 1 and 3, and B, A, B in weeks 2 and 4, with a day between sessions. That gives about 15 hard glute sets a week in week 1 and about 20 from week 2, inside the 10 to 20 our glute guide suggests.

The layout is our editorial choice. Once weekly sets match, training a muscle more often doesn't add growth (25 studies, and 67 in a later analysis), and our glute guide says two sessions a week suit most people; three shorter ones keep each session to 20 minutes. The British Heart Foundation advises a full day's recovery between strength sessions.

Sources 10, 11, 12

If a day is too hard, or you miss one

Drop back a step, or do 2 sets instead of 3: your step is the plan, not the date. Missed a session? Do the next one rather than doubling up; missed a week, repeat the week before; after two weeks or more off, start again at week 1's sets (our editorial suggestion).

Knee pain up to 2 out of 10 is fine, and up to 5 is acceptable if it has settled by the next morning, as our knee pain guide says: in trials of long-term muscle and joint pain, exercise that allowed some pain did as well as pain-free exercise. Otherwise shorten the range of split squats and step-ups. With a pinch at the front of the hip, go shallower; with pain on the outside of the hip, don't lie on that side and keep side-hip work light; with back pain, keep hinges light and stop any move that sends pain down a leg.

If missing a day makes you anxious, talk to your GP. In interviews after a month-long daily activity challenge, some people described feeling like a failure when they missed their targets.

What the evidence says

What 30 days can and can't changeEmerging evidence

Thirty days is too short to expect visible growth. The trials that measured glute growth were small and mostly ran 9 to 12 weeks: the main glute muscle grew by about 2 to 9% in 10 weeks, depending on the exercise, about equally with hip thrusts or squats over 9 weeks, and by about 15% in 12 weeks of leg presses. We have read only the abstracts of these trials, and none measured 4 weeks.

What a month can bring is stronger, steadier hips, more single-leg reps and a step or two up each ladder. In the thigh, growth became measurable around weeks 3 to 4 of hard training, early changes on scans can be swelling from muscle damage, and people differ hugely in how much and how fast they grow.

Sources 15, 16, 17, 18, 19, 20, 21

Hip thrusts or squats? BothEmerging evidence

In a 9-week trial that measured the glutes with MRI (magnetic resonance imaging) scans in 34 untrained adults, hip thrusts and back squats grew them about equally, and squats also grew the front and inner thighs more. The hip thrust's higher muscle activity didn't predict more growth, and muscle activity in one session isn't a validated guide to growth.

One 12-week trial in 22 trained women found squats grew the glutes more, but a 2025 review criticised its methods, and four other trials by its first author have since been retracted (this one hasn't been). So the challenge uses both: a bridge ladder that ends in the hip thrust, and split squats.

Sources 17, 22, 23, 24, 25, 26, 27, 28

Side-hip work, bands and bridgesEmerging evidence

Squats barely grew the side glutes, the gluteus medius and minimus, in the 9-week trial. In a 10-week trial of 17 adults, hip abduction training grew the upper part of the main glute muscle by about 10% and the side glutes by about 4%, while hip extension grew the main glute more overall.

Across 56 studies, single-leg bridges, side-lying leg raises with the hip turned slightly in and resisted side steps worked the side glutes hardest, and clamshells less. Elastic bands built strength like weights and machines across 8 studies. A two-leg bodyweight bridge is low effort for most adults, as our glute bridge guide explains, so the ladder moves on to single-leg, banded and loaded bridges.

Sources 17, 16, 29, 30

Home steps workEmerging evidence

In a small 6-week trial of 13 inactive young women, a 10-step bodyweight squat ladder, from two legs to one, increased glute thickness like barbell squats. One-leg and two-leg training built similar muscle across 9 studies, and reps lasting 0.5 to 8 seconds built similar muscle when the sets were hard.

Go as deep as you control: full squats grew the main glute muscle about three times as much as half squats in 17 men (6.7% against 2.2% over 10 weeks), and a review concluded that deep squats, learned with good technique and built up gradually, don't add knee or spine risk.

Sources 31, 3, 2, 15, 32

No plan can promise a shapeStrong evidence

Trials measure muscle size, not shape. Training a body part doesn't take fat off it (13 studies of 1,158 people), and where fat sits partly runs in genes. Stronger, gradually bigger glutes are a realistic aim; a new shape in 30 days isn't.

Sources 33, 34

For women and men alikeStrong evidence

Women and men gain lower-body muscle at similar rates, both relative to where they start and in absolute terms (29 studies), so the same steps work for both.

Source 35

Check first if this applies to youStrong evidence

Before day 1, answer the PAR-Q+ (the Physical Activity Readiness Questionnaire for Everyone): a yes to any of its 7 questions leads to follow-up questions that may send you to your doctor or a qualified exercise professional first.

In pregnancy, start anything new gently, and later on avoid lying flat on your back for more than a few minutes: prop your upper body up for bridges, or use the standing band moves. With pelvic girdle pain, limit one-leg moves such as step-ups and single-leg deadlifts. After a birth, the NHS advises avoiding high-impact exercise and heavy lifting to start with; a UK postnatal guideline suggests bringing in bridges, squats and lunges from about 2 to 4 weeks after the birth, as daily life allows, which is expert opinion. Start with our postpartum and pelvic floor guides.

With osteoporosis, hinge with a long back and avoid deep or loaded forward bending, as the UK consensus advises, and do back extensions slowly. With ME/CFS (myalgic encephalomyelitis or chronic fatigue syndrome), NICE (the National Institute for Health and Care Excellence) advises against programmes with fixed increases, which is what a challenge is.

Sources 36, 37, 38, 1, 39, 40

Warning signsStrong evidence

Call 999 or go to A&E for severe hip pain after a fall or injury, or if you can't walk or put weight on your leg, and for back pain with pain, tingling, weakness or numbness in both legs, loss of feeling around your genitals or bottom, or new problems peeing or pooing. Get an urgent GP appointment or contact NHS 111 for severe hip pain that started suddenly without a fall, a hot, swollen hip, or hip pain with a high temperature and feeling unwell. Contact NHS 111 for a knee you can't move or put weight on, or that is badly swollen, has changed shape, locks or gives way.

Dark, red or cola-coloured urine, or very painful, weak or swollen muscles in the days after a session: get medical help the same day. Call 999 or go to A&E for sudden, severe pain in any part of your body, and call 999 (911 in the US) for chest pain that doesn't go away, spreads to your arms, neck, jaw, stomach or back, or comes with sweating, feeling sick, light-headedness or breathlessness.

When exercise stops being good for youStrong evidence

Exercising too much, and worrying a lot about your weight and body shape, are among the signs of an eating disorder the NHS lists. Beat, the eating disorder charity, describes unhealthy exercise as rigid or punishing, often done in secret, done despite injury or illness, or used to make up for eating.

If that sounds familiar, talk to your GP, or call Beat's helpline (3pm to 8pm, Monday to Friday): England 0808 801 0677, Scotland 0808 801 0432, Wales 0808 801 0433 and Northern Ireland 0808 801 0434. Our eating disorders guide has more.

Sources 47, 48, 49

After the 30 daysEmerging evidence

A challenge is a start. Habits take longer than 30 days to form: in the four studies of a review that timed it, the typical time was 59 to 66 days, ranging from 4 to 335. In 389,481 fitness app users, training steadily in the first 28 days was the strongest sign of still training a year later.

So pick your next step before day 30: keep 2 glute sessions a week at your new steps, or move to the 8-week glute workout plan for the months that growth takes.

Questions people ask

Can you grow your glutes in 30 days?

You can make them stronger and get better at the moves in 30 days, but it's too short to expect visible growth. The trials that measured glute growth were small and mostly ran 9 to 12 weeks, and the main glute muscle grew by about 2 to 9% in 10 weeks. Give it months.

Does the 30-day glute challenge work at home?

Yes, if the sets are hard: light loads build muscle when the sets are taken close to your limit, bands built strength like weights, and in a small 6-week trial a bodyweight squat ladder grew the glutes like barbell squats. One-leg moves and slower lowering keep home sets hard.

Should I train glutes every day?

No: once weekly sets match, training a muscle more often doesn't add growth. Three shorter sessions a week with a rest day between give about 15 to 20 hard glute sets a week, inside the 10 to 20 our glute guide suggests.

Hip thrusts or squats?

Both. In a 9-week MRI trial they grew the glutes about equally, and squats grew the front and inner thighs more, so lean on the bridge ladder and hinges if that matters to you. One trial that favoured squats has had its methods criticised.

Do glute bridges, band walks and clamshells work?

Two-leg bodyweight bridges are a starting point, not enough on their own for most adults, so the ladder moves to single-leg, banded and loaded bridges. Single-leg bridges, side-lying leg raises and resisted side steps work the side glutes hardest, while clamshells score lower.

Will it lift or round my bum?

No plan can promise a shape: trials measure muscle size, training doesn't remove the fat over a muscle, and where fat sits partly runs in genes. Stronger, gradually bigger glutes are a realistic aim.

How many sets and reps?

About 5 hard glute sets a session in week 1 and 7 from week 2, in ranges of 6 to 15 reps (12 to 20 for side-hip moves), stopping 1 to 3 reps short. Move up a step rather than going past about 20 reps.

My knees, hips or back hurt. Can I still do it?

Usually, with changes. Knee pain up to 2 out of 10 is fine, and up to 5 if it has settled by the next morning; go shallower for a hip pinch, keep side-hip work light with outer hip pain, and keep hinges light with back pain. Get urgent help for the warning signs on this page.

Is this the same as the 30-day squat or butt challenge?

The squat challenge trains your legs with squat steps; this one adds bridges, hip thrusts, hinges, step-ups and side-hip work, which reach parts of the glutes squats barely train. Many viral butt challenges pile up reps of one easy move every day; this one makes each move harder instead, with rest days.

What should I do after 30 days?

Keep 2 glute sessions a week at your new steps, or move to the 8-week glute workout plan. Habits take about two months on average to form, so choose your next step before day 30.
