Guides
A pelvis tipped forward deepens the curve in your lower back: the belly pushes out even on a lean frame, and after a while on your feet the lower back may start to ache or pull. The position itself is not a disease. It becomes a problem when your hip flexors stay short while your glutes and deep abdominals stop working.
The pelvis tips forward so the lower back over-arches and the belly appears pushed out even in fit people; often spotted in photos or a posture scan rather than felt. Long sitting plus quad/hip-flexor dominance is the classic recipe; sometimes paired with a grumbling lower back after standing.
Sitting keeps the hip flexors short and the glutes off duty; standing up, the short flexors pull the pelvis forward and the sleepy glutes and deep core don’t counter it. The lower back arches to compensate and quietly absorbs load all day. It’s a tug-of-war the front is winning; the fix is lengthening the front while strengthening the back of the rope.
Specifics
Find specific answers about setup, dosage and timing, with the same numbers shown in the plan further down the page.
01
Strengthen the muscles behind the pelvis. The 3 × 40-second stretch per side is only the protocol’s first phase; the second, 3–5 weeks long, is glute bridges with a deliberate 2-second squeeze at the top and slow dead bugs with the lower back glued to the floor, 3 times a week. The protocol pairs the two because the front and back of the pelvis work together.
02
Your sense of position changes in 2–3 weeks; a visible change on photos usually takes 8–12 weeks of consistent work. The single biggest lever on hip-flexor length is interrupting sitting every 30–45 minutes. Kallen handles that with Reverse Sitting, handing you one Mobility Snack at the end of each work block.
03
Monthly, not daily. Posture change is honest but slow, so a daily mirror check mostly shows nothing moving. The protocol recommends filming or scanning once a month; Kallen’s side-on posture scan reads anterior pelvic tilt, so you compare two readings taken the same way.
These signs do not mean you must stop moving. Have them assessed in person and continue only with movement that is safe for you.
In Kallen: turn on Reverse Sitting
Start a 25, 45 or 60-minute work block and let Kallen track the time. When it ends, Kallen draws one of 19 Mobility Snacks matched to the tight areas in your profile. Each takes 35–50 seconds; 10 can be done seated and the rest standing beside your desk. Then you return to work.
This is how the protocol appears in the app. The coach adapts the pace and dosage to your measurements. You advance when you meet the phase criterion, not when a date arrives.
Phase 1 · 2-3 weeks
Goal
Restore hip-flexor length and learn the neutral-pelvis position
Dosage
Stretch 3x40s per side daily with the back-pocket glute squeezed; 90/90 breathing 5 min; exhale fully, feel the ribs drop.
Move on when
You can find and hold neutral pelvis on cue; the hip front stops feeling like a guy-wire.
Exercises
Phase 2 · 3-5 weeks
Goal
Glutes and deep core that actually hold the pelvis level
Dosage
Bridges with a deliberate 2s glute squeeze at the top; dead bugs slow with the low back glued down. 3x/week.
Move on when
Glutes fire before the lower back in bridges; hollow hold 30s+ with ribs down.
Exercises
Phase 3 · 3-6 weeks
Goal
Keep the neutral pelvis in real movement; hinging, carrying, striding
Dosage
Hinge with the "ribs over pelvis" cue; Pallof slow, 2x10 per side, 2-3x/week.
Move on when
A posture scan or side photo shows the change; standing tall feels like rest, not work.
Exercises
Position sense changes in 2-3 weeks; visible posture change on photos usually takes 8-12 weeks of consistent work. This one rewards patience and monthly (not daily) progress checks.
Put your hands on your pelvis: thumbs on the bony points at the front, fingers over the pubic bone. If your hands clearly angle down and forward, your pelvis is tipped forward. A second signal: lying on your back, a whole hand sliding freely under your lower back is a lot of space.
Not in itself. Plenty of people carry this position with no symptoms at all, and it does not need “fixing” for looks. It is worth working on when symptoms come with it: a pulling lower back, tight hip flexors, glutes that have gone quiet.
No. Crunches mostly train trunk flexion, and this is a different job: lengthening the hip flexors, waking the glutes, and teaching your trunk to hold position without arching. Anti-extension work such as planks and dead bugs does far more here.
