Pull-In On Stability Ball
Pull-In On Stability Ball Exercise Description
The stability ball pull-in (often called a ball knee tuck) is an anterior core exercise performed from a plank position with the lower legs on a stability ball. You dynamically flex the hips and knees to roll the ball toward your torso while maintaining a neutral spine and level pelvis. Primary emphasis is on the rectus abdominis and hip flexors; the obliques and transverse abdominis assist in lumbopelvic control, while the serratus anterior and scapular stabilizers support the shoulder girdle. Because your body is leveraged over the ball, it challenges anti‑extension strength and total‑body coordination. Done with smooth, controlled motion, it teaches bracing, shoulder stability, and precise hip movement without lumbar collapse or excessive rounding.

How To Do The Pull-In On Stability Ball Exercise
‘- Place the ball on a non‑slip surface. Set up in a high plank with shins or tops of feet on the ball and hands under shoulders.
– Form a straight line from head to heels. Brace the trunk; ribs down; glutes lightly engaged.
– Spread fingers and “grip” the floor; press the ground away to protract slightly and prevent scapular winging. Keep shoulders away from ears.
– Inhale to prepare. On the exhale, flex hips and knees to draw the ball toward your torso.
– Keep the lumbar spine neutral—no sagging or aggressive rounding; pelvis stays level.
– Stop when knees are under hips or just before the low back wants to flex.
– Reverse under control, extending hips and knees to return to a strong plank without hyperextending the lumbar spine.
– Keep gaze slightly ahead of hands for a neutral neck. Move smoothly—avoid bouncing or using momentum.
– Make it easier by starting with thighs on the ball; harder by placing the ball closer to the ankles.
Pull-In On Stability Ball Tips
‘- Place the stability ball on a non-slip surface before getting into position.
– Set up in a high plank with hands under shoulders and shins or feet resting on the ball.
– Form a straight line from head to heels, keeping ribs down and trunk braced.
– Lightly engage the glutes to help maintain a neutral, stable plank.
– Spread your fingers, grip the floor, and press the ground away to slightly protract the shoulder blades.
– Keep shoulders away from ears to support stable shoulder positioning.
– As you exhale, flex hips and knees to roll the ball toward your torso while keeping the pelvis level.
– Keep the lumbar spine neutral—no sagging or aggressive rounding—as the ball moves.
– Stop the tuck when knees are under hips or just before the low back wants to flex.
– Return to the starting plank under control, extending hips and knees without hyperextending the low back.
– Keep your gaze slightly ahead of your hands and move smoothly, avoiding bouncing or momentum.
– Make the exercise easier by starting with thighs on the ball, or harder by placing the ball closer to the ankles.
Pull-In On Stability Ball Beginner Introduction
With the stability ball pull-in (often called a ball knee tuck), the body forms a straight, plank-like line while the lower legs rest on a stability ball and the hands support the upper body on the floor. From this balanced position, the ball glides in and out beneath the legs as the hips and knees bend and straighten, challenging the abs and hip flexors to work against gravity while the spine and hips remain steady.
This movement blends core strength with shoulder and upper-back stability. The abs, side abs, and deep core muscles work together to control the mid‑section, while muscles around the shoulders and chest help keep the upper body solid against the ground. Because the body is stretched out over the ball, the exercise emphasizes control against excessive arching through the lower back and encourages smooth, coordinated motion through the whole body rather than relying on momentum.
