Seated Pelvic Tilt
The seated pelvic tilt is a small, gentle rock of the pelvis while sitting upright on a chair or exercise ball, rounding the low back slightly and then letting it arch slightly. It is a mobility and awareness movement for the low back and pelvis that can be done anywhere there is a seat.
Also called: Seated Pelvic Tilts, Chair Pelvic Tilt, Sitting Pelvic Tilt, Seated Pelvic Rock · Equipment: bodyweight · Pattern: isolation
Step by step
- Sit tall towards the front of a firm chair or an exercise ball, feet flat and hip-width apart, knees roughly over your ankles.
- Rest your hands on your thighs and let your shoulders relax.
- Breathe out and gently roll your pelvis backwards, so your low back rounds slightly and you sit a little more on the back of your sitting bones.
- Breathe in and roll your pelvis forwards, so your low back arches slightly and you sit a little more on the front of your sitting bones.
- Keep your head and shoulders roughly still, as the movement comes from the pelvis.
- Rock slowly and smoothly between the two positions within a comfortable range.
- Finish sitting tall in the middle, balanced evenly on your sitting bones.
- Sit tall, then rock the pelvis gently back and forwards
- Roll onto the back of your sitting bones, then the front
- Small and smooth, and keep breathing
- Head and shoulders stay quiet while the pelvis moves
- You are finding the middle, not working hard
- If anything feels uncomfortable, your healthcare provider is the right call
In VALDA, these cues are one tap away on the exercise while you train.
What it trains
| Muscle | Role | Evidence |

Evidence grades: A = strong research base · B = good · C = limited · D = coaching consensus.
What goes wrong, and the fix
Slumping the whole spine
Fix: Keep your chest open and let only the low back round slightly.
Leaning the trunk instead of tilting
Fix: Keep your head and shoulders over your hips and let the pelvis do the rocking.
Forcing a big range
Fix: Keep the rock small and move only as far as feels comfortable.
Holding the breath
Fix: Breathe out as you roll back and breathe in as you roll forwards.
Ball rolling under you
Fix: Set your feet flat and a little wider so the ball stays still beneath you.
What the research says
Rehab & prehab
- Reps and pace — The pelvic tilt is commonly done as a set of slow, small repetitions, often around 10, with the quality of the movement valued over the count.
- Placement — Some people use it as a short break from sitting at a desk, or in a warm-up or cool-down. A firm chair is all that is needed.
- Chair or ball — An exercise ball adds a small balance element compared with a chair. There is no direct research comparing the two.
- Research — There is no direct research on the pelvic tilt as an exercise. It is taught as common practice for feeling how the low back and pelvis move.
Swap it mid-workout
