ProBody Pilates Yoga Ball – Gym Grade Exercise Ball (Blue, 75cm) | Sizes 45/55/65/75/85 cm, 330 lb Load, CA 10P Cert, PT & Prenatal Use, Recommended by OBs, Pump

PICK YOUR SIZE FOR YOUR HEIGHT — 45 cm for kids and shorter PT users / 55 cm for 4’4″-5’1″ / 65 cm for 5’1″-5’8″ (most popular) / 75 cm for 5’8″-6’3″ / 85 cm for 6’3″+. The workout ball is intentionally unstable, so your deep core, lower back, and pelvic floor work continuously to keep you upright — turning a desk sit, a lumbar PT homework set, or a labor-prep hip rotation into real strengthening. GYM-GRADE ANTI-BURST PVC, DUAL-ACTION PUMP INCLUDED — Thick non-toxic PVC, tested to 880 lbs; if punctured, it deflates slowly rather than bursting — the safety pattern PT clinics actually look for. The box includes the swiss ball, a dual-action pump, two ball plugs, a stopper remover, and a printed exercise guide. Inflate to 80-90% the first time, let the ball settle 24 hours, then top it up.
