Gluteal activity with ball moving against the wall, hip flexion and extension (Coordination, pelvic stabilization (level 2) - hip flexion/extension, ball on wall; 02)

Stand side onto the wall with the ball between your thigh and the wall.

Press the ball up against the wall using your thigh and hip muscles and then lift your leg off the floor with your knee bent and gently push the ball against the wall with this thigh.
In this position, cross your arms and move the leg that is holding the ball forward and as far backward as possible by moving through the hip.
Keep your hips square and your pelvis and lower back stable.
As you move the ball backwards, be sure not to change the position of your lower back.

Repeat and then swap legs.
