We recommend inflating to 80%-90% for a soft, squishy feel that provides superior core engagement and prevents slipping. Over-inflation may cause distortion or damage. Why Professional Studios Choose 25cm Over the Standard 9-Inch Ball If you’ve noticed that our ball is slightly larger (25cm/9.8in) than the generic 9-inch balls on the market, that is by design. In the world of professional Pilates and Physical Therapy, those extra 2 centimeters unlock a new level of stability and versatility that smaller balls simply cannot provide. ### THE PRO-ADVANTAGE: WHY SIZE MATTERS Superior Spinal Support: The 25cm diameter provides a larger surface area. When placed under your lower back (sacrum) or upper back (thoracic), it distributes pressure more evenly, offering a more stable and "held" feeling than smaller, more "fidgety" balls. Deeper Myofascial Release: For chest opening and spinal extension, the slightly larger arc allows for a deeper, more effective stretch. It’s the preferred size for practitioners looking to correct "computer posture" and open up tight shoulders. The "Perfect Fit" for All Body Types: While 9-inch balls can feel lost under larger frames or taller individuals, the 25cm design is inclusive, providing the necessary lift and resistance for everyone from petite yogis to athletes. ### THE MASTER INSTRUCTOR’S SECRET: THE 80% RULE Crucial Tip for the Perfect Feel: Most users make the mistake of inflating Pilates balls until they are rock-hard. A professional Pilates ball is meant to be "squishy," not like a basketball. For Core & Inner Thigh Work: Inflate to 80-85%. This allows the ball to contour to your legs, providing better grip and deeper muscle activation. For Back Support & Relaxation: Inflate to 70%. A softer ball acts as a dynamic cushion, cradling your spine and allowing your nervous system to relax. If the ball feels "too big," simply release a small amount of air. The 25cm design gives you the freedom to "size down" by adjusting the air, whereas a small ball can never be made larger.
