Sitting Knee Raise On A Stability Ball
Sitting Knee Raise On A Stability Ball Exercise Description
The Sitting Knee Raise on a Stability Ball trains hip flexion while demanding steady lumbopelvic control. Seated on the ball, you lift one knee at a time without leaning or shifting, emphasizing the hip flexors (iliopsoas and rectus femoris) with assistance from sartorius and the tensor fasciae latae. Because the ball is unstable, your abdominal wall (rectus abdominis and obliques) and deep spinal stabilizers engage isometrically to maintain a neutral spine and level pelvis. This drill improves coordination of the hip flexors with trunk stability, reinforcing clean movement patterns for controlled marching and step initiation. Keep the range of motion pain‑free and the ball as still as possible to prioritize technique over amplitude. It’s a simple, low-load way to practice precise hip flexion mechanics while reinforcing posture and balance.

How To Do The Sitting Knee Raise On A Stability Ball Exercise
‘- Choose a ball height that allows your hips and knees to be near 90° when seated.
– Sit on the top-center of the ball; feet flat, hip-width; toes pointing forward.
– Stack ribs over pelvis; maintain a neutral spine; shoulders down and back.
– Lightly brace the abdominal wall as if preparing to exhale through pursed lips.
– Place hands on hips or lightly on the ball for balance (avoid gripping).
– Without leaning back or side bending, lift one knee by flexing the hip; keep pelvis level.
– Raise only as high as you can without moving the ball or hiking the hip.
– Lower the foot with control; keep the supporting leg stable and the arch grounded.
– Alternate legs, moving smoothly and keeping your torso tall.
– Avoid bouncing, holding your breath, turning the lifted leg outward, or letting the stance knee collapse inward.
Sitting Knee Raise On A Stability Ball Tips
‘- Choose a ball height that lets your hips and knees be near 90° when seated.
– Sit on the top-center of the ball with feet flat, hip-width apart, and toes pointing forward.
– Stack your ribs over your pelvis, keeping a neutral spine with shoulders down and back.
– Lightly brace your abdominal wall as if preparing to exhale through pursed lips.
– Place your hands on your hips or lightly on the ball for balance, avoiding gripping.
– Lift each knee by flexing the hip without leaning back or side bending.
– Keep your pelvis level and the ball as still as possible as you raise the knee.
– Raise the leg only as high as you can without moving the ball or hiking the hip.
– Lower the foot with control, keeping the supporting leg stable and the arch grounded.
– Alternate legs smoothly while keeping your torso tall.
– Keep the range of motion pain-free and prioritize technique over how high you lift.
– Avoid bouncing, holding your breath, turning the lifted leg outward, or letting the stance knee collapse inward.
Sitting Knee Raise On A Stability Ball Beginner Introduction
The Sitting Knee Raise on a Stability Ball is a seated, balance-based drill that uses an unstable surface to challenge hip movement and body control at the same time. While sitting on the center of the ball with the legs bent, one leg is lifted from the ground in a marching-style motion, then traded for the other side. The moving leg works the hip flexors and the front of the thigh, while the supporting leg helps provide a steady base.
Because the ball can shift under the body, the abs, side abs, and lower back work together to hold the trunk upright and the hips level as each knee rises and lowers. This combination turns a simple leg lift into a coordination exercise that links hip action with a stable middle. It can be a gentle option for practicing smooth, precise hip lifting that carries over to walking or stepping tasks, while also reinforcing an aligned sitting posture and a sense of overall balance.
