Anterior Pelvic Tilt: How to Tell If You Have It and How to Fix It
Anterior pelvic tilt — often shortened to APT — is what you see when the top of the pelvis tips forward, the lumbar spine arches more than usual, and both the belly and backside can look more prominent when you stand. If you are searching for an anterior pelvic tilt fix or wondering whether APT is behind your lower-back tightness, you are usually dealing with a visible muscle imbalance, not a permanent bone shape. The good news: with targeted stretching, strengthening, and habit changes, most people can reduce excessive tilt noticeably.
What anterior pelvic tilt looks like
Standing side-on, signs of anterior pelvic tilt include:
- The front of your beltline angles downward
- A pronounced inward curve at the lower back (lordosis)
- The abdomen appearing to stick out even at a normal body weight
- Glutes that look lifted or "shelved" behind you
This is the classic lower-body postural signature described in Janda's work. It is not the same as sway-back posture, where the pelvis shifts forward on the legs and the upper trunk leans back — a flatter, hang-on-the-ligaments pattern. If your hips sit ahead of your ankles but your lower back looks relatively flat, read the sway-back guide instead.
Anterior pelvic tilt and lower-crossed syndrome
APT is the visible face of lower-crossed syndrome — tight muscles on one diagonal, weak muscles on the other:
| Diagonal | Typically tight | Typically weak |
|---|---|---|
| Front line | Hip flexors, iliopsoas, rectus femoris | Abdominals, rectus abdominis |
| Back line | Lumbar erector spinae, erector spinae | Gluteals, gluteus maximus |
Hours of sitting shorten the front line while the back line overworks to hold you upright. The pelvis tips forward because the hip flexors pull down on the front of the pelvis and the lumbar extensors pull up on the back. Until you lengthen the tight side and activate the weak side, any pelvic tilt fix will fight the same pattern.
Explore the hip region hub and core region hub for how these segments connect.
How much pelvic tilt is normal?
Not all anterior tilt is a problem. A small amount of anterior pelvic tilt — often cited around ten to fifteen degrees in clinical texts — is normal and helps distribute load through the lumbar spine. APT becomes worth addressing when:
- The tilt looks clearly exaggerated in a relaxed standing photo
- You cannot reduce the arch voluntarily without feeling like you are straining
- Lower-back fatigue, hip-flexor tightness, or related postural drift (like forward head posture) accompany the visible tilt
Think of it as excessive tilt relative to your neutral, not zero tilt. Your goal is a pelvis that can move through range and rest in a balanced middle — not a forced flat back.
How to test for anterior pelvic tilt
Hand-under-low-back test. Stand against a wall with your heels, hips, and shoulders lightly touching. Slide your hand into the space behind your lower back. A small gap — about one hand's thickness — is normal. If you can fit a fist or more without effort, and your beltline clearly slopes forward, APT is likely.
Side photo. Photograph yourself standing naturally from the side, or use our posture scan for objective trunk alignment. Compare to trunk lean measurements if you want numbers over guesswork.
Hip-flexor length check. Lying on the edge of a bed, pull one knee to your chest. If the opposite thigh lifts off the surface, tight hip flexors may be contributing — a common driver of APT.
The anterior pelvic tilt fix routine
Run this sequence most days. Mobilise first, then strengthen.
Release tight hip flexors and lumbar extensors
- Hip flexors PIR stretch — contract-relax work for the iliopsoas group
- Standing doorframe hip flexor stretch — lengthens the front of the hip with an upright trunk
- Hip flexor foam roll — soft-tissue release before stretching
Spend five to eight minutes here daily if you sit a lot.
Strengthen abdominals and glutes
- Milo curl-up — lower abdominal control without cranking the neck
- Supine knee hug — teaches posterior pelvic tilt from the floor
- Glute medius isometric — lateral hip stability
- Bird dog — coordinates trunk and hip extension
Strength sessions two to three times per week build the capacity to hold a neutral pelvis when standing and walking.
Carry it into standing
Practice stacking — ear over shoulder over hip — using a wall posture check or the principles in good standing posture. APT correction is not just floor work; it is what you do when you get up from the desk.
Daily habits that support your pelvic tilt fix
- Break up sitting every 30–45 minutes; see desk sitting posture for setup tips
- Avoid sleeping on your stomach if it increases your morning arch — sleeping posture covers pillow setup
- Pair hip work with general guidance from posture exercises for a full-chain approach
Most people see visible change in four to eight weeks with consistent mobility and strength work. Track with photos or a scan so you know the anterior pelvic tilt fix is working, not just feeling different on good days.
