Anterior pelvic tilt (APT) is when your pelvis rotates forward — the top tipping toward the front of your body. It causes an exaggerated lower back arch, a belly that sticks out (even at low body fat), and tight hip flexors that complain after long walks or runs.
It’s extraordinarily common in desk workers and anyone who sits a lot. The fix isn’t a single magic stretch — it’s a balanced approach that releases the tight muscles, strengthens the weak ones, and rebuilds the postural pattern over weeks.
Here’s a clear, evidence-based guide to anterior pelvic tilt: what causes it, how to identify it, and the routine that addresses it.

What anterior pelvic tilt actually is
Your pelvis can tilt three ways:
- Neutral: the top of the pelvis is roughly level with the bottom; spine has natural curves but isn’t exaggerated
- Anterior tilt: the top tips forward, increasing lower back arch
- Posterior tilt: the top tips backward, flattening the lower back
A small degree of anterior tilt is normal. Excessive APT is when the tilt becomes pronounced enough to change posture and cause symptoms.
In APT, the pelvic muscles are out of balance:
- Tight (overactive): hip flexors (psoas, rectus femoris), lower back erectors
- Weak (underactive): abdominals (especially deep core), glutes (especially gluteus maximus), hamstrings (sometimes)
This pattern shows up because the muscles that pull the pelvis forward (hip flexors and back extensors) are stronger than the ones that pull it back (abs and glutes). Sitting all day is the most common cause.
Signs you have anterior pelvic tilt
Common indicators:
- Pronounced lower back arch when standing
- Sticking-out belly even at lean body fat
- Butt sticks out (overemphasized lordosis)
- Lower back pain or stiffness, especially after sitting or standing for long periods
- Tight hip flexors — front of hip and thigh feels tight
- Difficulty engaging your glutes during squats or deadlifts
- Pain or tightness in the front of your hips when running or walking long distances
- Poor pelvic position during exercise — back arches under load
Not all APT causes pain. Mild to moderate tilt is common and asymptomatic in many people. The fix matters most when symptoms are present or function is limited.
How to test for it
Two simple home tests:
Wall test
- Stand with your back against a wall, heels 6 inches from the wall
- Slide your hand behind your lower back
- Normal: your hand fits with little space (1–2 fingers)
- APT: your full hand or fist fits with extra space — your lower back is overarched
Wall slide test
- Stand with your back flat against a wall
- Try to flatten your lower back to the wall by tilting your pelvis backward
- If your lower back stays gapped from the wall, you have functional APT
If both tests confirm excess arch and you have symptoms, working on APT makes sense.
What causes APT
Several factors typically combine:
Prolonged sitting (most common)
Sitting shortens hip flexors (especially psoas) over years. When you stand, those tight hip flexors pull the pelvis forward.
Weak abdominals
Without strong deep core muscles to counter the pull of the hip flexors and back extensors, the pelvis drifts forward.
Weak glutes
Gluteus maximus pulls the pelvis backward. Weak glutes mean the pelvis can’t be held in neutral.
Poor exercise habits
Doing lots of hip flexor-dominant exercises (cycling, sit-ups) without balancing posterior chain (deadlifts, hip thrusts, glute bridges).
Pregnancy
Hormonal changes loosen pelvic ligaments and the growing belly pulls the pelvis forward. A 2024 study in pregnant women with low back pain documented improvements in pelvic tilt and pain with targeted alignment exercises.1

Genetic and structural
Some people have pelvic anatomy that predisposes to more anterior tilt regardless of training.
Heavy belly weight
Excess abdominal weight can pull the pelvis forward mechanically.
The basic fix: balance the muscles
The strategy:
- Stretch tight muscles: hip flexors, lower back extensors
- Strengthen weak muscles: abs (especially deep core), glutes
- Practice the corrected position repeatedly until it becomes default
Expect 4–8 weeks of consistent work for noticeable changes. Posture is a habit at the muscle and nervous system level — it doesn’t shift overnight.
Stretches for tight muscles
1. Kneeling hip flexor stretch
- Kneel on one knee with the other foot in front (like a low lunge)
- Tuck your tailbone under (posterior pelvic tilt)
- Squeeze the glute on the kneeling-leg side
- Push your hips slightly forward
- Hold 30–60 seconds, repeat 2–3 times per side
The “tuck the tailbone” + “squeeze glute” cues are critical. Don’t just lean forward — that stretches the wrong tissue.
2. Couch stretch
A more aggressive hip flexor stretch:
- Place one knee on the floor against a wall or couch (knee touching the wall, foot up against it)
- Step the other foot forward into a lunge
- Tuck tailbone, squeeze glute on the stretching-leg side
- Hold 30–90 seconds per side
3. Cat-cow stretch
- Hands and knees position
- Slowly arch your back (cow), then round it (cat), tucking pelvis
- 8–10 cycles, focusing on the pelvic tilt motion
This trains conscious control over the pelvic tilt position.
4. Child’s pose
- Sit back on heels with arms extended forward
- Holds the lower back in a stretched position
- 60+ seconds
Strengthening for weak muscles
1. Glute bridges
- Lie on your back, knees bent, feet flat
- Squeeze glutes and lift hips so body forms a straight line from knees to shoulders
- Hold 1–2 seconds at top, lower slowly
- 3 sets of 12–15 reps
Focus on glute squeeze rather than arching your lower back to lift higher.

2. Dead bug
- Lie on your back, arms reaching toward ceiling, legs in tabletop position
- Slowly lower opposite arm and leg toward floor while keeping lower back pressed to floor
- Return to start, alternate sides
- 3 sets of 8–10 reps per side
This trains the deep core to maintain pelvic position against limb movement.
3. Plank
- Standard forearm plank
- Tuck pelvis slightly (slight posterior tilt)
- Squeeze glutes
- Hold 20–60 seconds, 3 sets
The pelvic tilt and glute squeeze cues are essential — most people plank with sagging hips, which doesn’t address APT.
4. Hip thrust
- Sit on the floor with upper back against a bench
- Roll a barbell or weight over your hips
- Drive hips up by squeezing glutes
- 3 sets of 8–12 reps
Stronger glutes are one of the most important pieces of the APT fix.
5. Pallof press (anti-rotation)
- Stand sideways to a cable column or resistance band attached at chest height
- Hold the handle with both hands at chest, then press it straight out from your chest
- Resist the band trying to rotate you
- 3 sets of 8–10 reps per side
Builds anti-rotational core strength.
A daily 10-minute APT routine
A practical routine you can do daily:
| Exercise | Time |
|---|---|
| Kneeling hip flexor stretch | 60 sec each side |
| Cat-cow | 1 min |
| Child’s pose | 60 sec |
| Glute bridges | 2 sets of 15 |
| Dead bug | 2 sets of 8 each side |
| Plank | 2 × 30 sec |
10 minutes total. Done daily for 4–8 weeks, this addresses the major contributors to APT.
What to add for resistant cases
If 8 weeks of basic work hasn’t moved the needle:
- Heavier glute work — barbell hip thrusts, single-leg deadlifts, Bulgarian split squats with focus on glute drive
- Dedicated core program — McGill big three (curl-up, side plank, bird dog) is well-studied for back health
- Reduce sitting — standing desk, walking breaks every 30–60 minutes
- See a physical therapist — for individualized assessment and targeted interventions
Persistent symptoms despite consistent work warrant professional evaluation. Some apparent APT cases have other underlying issues (femoral retroversion, leg length discrepancy, genuine spine pathology) that need different approaches.
What probably won’t fix APT
A few common myths:
- Crunches and sit-ups — don’t strengthen the deep core that matters for posture; can actually reinforce hip flexor dominance
- Stretching alone — without strengthening the opposing muscles, the imbalance returns
- One magic exercise — APT is a pattern, not a single muscle problem
- Posture braces and devices — don’t train your nervous system or build strength
- A single session of “fixing your alignment” — has to be repeated thousands of times to become default
Common questions
How long does it take to fix APT? Visible changes in 4–8 weeks of daily work. Lasting changes that hold under stress take 3–6 months.
Will my belly look smaller if I fix it? Often, modestly. The “sticking-out belly” component of APT can give a few centimeters of apparent waistline reduction without losing weight, just by improving pelvic position.
Should I stop sitting? You don’t have to. Just take regular standing breaks (every 30–60 minutes), stretch hip flexors daily, and do the strengthening work.
Will running make it worse? Not inherently. Running with poor pelvic control can aggravate hip flexors. Focus on running form, glute engagement, and cadence — see running cadence and running form.
Is APT linked to lower back pain? Sometimes. Severe APT can contribute to lumbar lordosis-related pain, but pain has many causes. Don’t assume APT is the cause without evaluation.
Is posterior pelvic tilt a thing? Yes — opposite pattern, less common, often from over-tucking pelvis or weak hip flexors. Same balance principles apply, opposite direction.

Bottom line
Anterior pelvic tilt is a common postural pattern caused by tight hip flexors and back extensors plus weak abs and glutes — usually from sitting all day. The fix is balanced: stretch the tight muscles, strengthen the weak ones, practice the corrected pelvic position. Ten minutes of daily work over 4–8 weeks moves the needle for most people. If symptoms persist or function is limited, see a physical therapist for individual assessment.
