Seated Lumbar Extension Flexion On Stability Ball
Seated Lumbar Extension Flexion On Stability Ball Exercise Description
Seated Lumbar Extension–Flexion on a Stability Ball trains controlled lumbar motion through coordinated pelvic tilting while maintaining overall trunk alignment. The primary movers are the lumbar extensors (erector spinae and multifidus) during extension and the abdominal muscles (rectus abdominis with assistance from the obliques) during flexion; the transversus abdominis and hip stabilizers contribute to postural control. The ball’s unstable surface requires continuous, low-level co-contraction to keep the ribcage stacked over the pelvis and the feet grounded, promoting precise lumbopelvic coordination rather than large ranges of motion. Emphasis is on slow, segmental control—moving the lumbar spine while keeping the thoracic spine and head relatively quiet. Use a small, comfortable range and prioritize neutral alignment at the start and finish positions to avoid excessive arching or rounding.

How To Do The Seated Lumbar Extension Flexion On Stability Ball Exercise
‘- Select a ball height that lets your hips and knees rest near 90 degrees with feet flat and hip-width apart.
– Sit on the top of the ball, ribs stacked over pelvis, shoulders relaxed, gaze forward, chin neutral.
– Place hands on hips or across chest for balance; distribute weight evenly through both sit bones and feet.
– Set a light abdominal brace to stabilize; avoid holding your breath.
– Posteriorly tilt the pelvis to “tuck the tailbone,” creating gentle lumbar flexion while keeping the chest quiet.
– Reverse by anteriorly tilting the pelvis to “untuck,” creating a small, controlled lumbar extension without flaring the ribs.
– Move slowly and smoothly, keeping knees facing forward and avoiding bouncing or shifting side to side.
– Stay within a comfortable, pain-free range; finish by returning to a neutral spine and pelvis.
Seated Lumbar Extension Flexion On Stability Ball Tips
‘- Choose a ball height that lets your hips and knees rest near 90 degrees with feet flat and hip-width apart.
– Sit with ribs stacked over the pelvis, shoulders relaxed, gaze forward, and chin neutral.
– Place hands on hips or across the chest and distribute weight evenly through both sit bones and feet.
– Maintain a light abdominal brace throughout and avoid holding your breath.
– Initiate movement by posteriorly tilting the pelvis to “tuck the tailbone” and create gentle lumbar flexion while keeping the chest quiet.
– Reverse by anteriorly tilting the pelvis to “untuck,” creating a small, controlled lumbar extension without flaring the ribs.
– Move slowly and smoothly to emphasize segmental lumbar control while keeping the thoracic spine and head relatively quiet.
– Keep the knees facing forward and avoid bouncing or shifting side to side on the ball.
– Keep the ribcage stacked over the pelvis and the feet grounded to maintain alignment on the unstable surface.
– Stay within a comfortable, pain-free range and always finish by returning to a neutral spine and pelvis.
Seated Lumbar Extension Flexion On Stability Ball Beginner Introduction
Seated Lumbar Extension–Flexion on a Stability Ball is a controlled lower-back mobility exercise performed while sitting on a stability ball. The movement centers on gentle rocking of the pelvis to alternately round and slightly arch the lower spine, while the upper back and head stay relatively steady. The ball’s unsteady surface adds a balance challenge, so the body uses small, continuous muscle effort to stay upright and organized over the feet.
This exercise highlights the lower back muscles as they guide the extension phase and the abs and side abs as they guide the flexion phase. Deep core muscles and the hips contribute to steady posture throughout. The overall theme is precision rather than big, dramatic movement: a small, comfortable range of motion, smooth pacing, and an emphasis on coordination between pelvis and lower spine. That combination makes it well suited for practicing awareness of spinal position and refining how the core and hips work together during seated movement.
