A Swiss ball should be inflated until it feels firm yet still allows a slight indentation when pressed with your fingers. When you sit on the ball, your knees should be at a 90-degree angle with your thighs parallel to the floor. Avoid over-inflating, as this can make the ball too rigid and less stable, reducing both comfort and effectiveness during exercises.
