PICK YOUR SIZE FOR YOUR HEIGHT — 45 cm for kids and shorter PT users / 55 cm for 5'0"-5'5" / 65 cm for 5'6"-6'0" (most popular) / 75 cm for 6'1"-6'5" / 85 cm for 6'6"+. 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.
RECOMMENDED BY OBSTETRICIANS, MIDWIVES, DOULAS & PHYSICAL THERAPISTS — Expecting and postpartum mothers reach for it as a pregnancy ball, birthing ball, and labor ball for gentle hip rotation and pelvic mobility (always confirm with your OB or midwife). Work-from-home professionals swap their desk chair for active sitting on a yoga ball chair or exercise ball chair. Older adults and lumbar-rehab patients use it for guided PT homework between clinic visits.
AT YOUR DESK, IN THE CLINIC, OR AT THE BIRTHING CENTER — Use it through an 8-hour active-sitting workday, the third trimester and early labor, daily 10-minute core sessions, or PT homework between visits. Often called a gym ball, fitness ball, yoga ball large, physio ball, physical therapy ball, or fitball. Pairs naturally with a yoga mat, foam roller, resistance bands, and a peanut ball for labor — add the ProBody Pilates Ring Set for a full low-impact circuit.
