Lean on the ball at a slight incline angle. Feet flat on the ground for support and
hands at your side for stability. Your hips are low to the ground and your legs at a
90 degree angle.
Raise your hips by rolling the ball back at the same time.
Keep feet in place.
Hold for 1-2 seconds, then roll back to the starting position.
Tips
Try to avoid sitting on the ground, keep a constant tension of the muscle.
