The Wellrox 45-55cm Exercise Ball is built for anyone who wants a reliable, versatile fitness tool without the hassle of manual inflation. Unlike standard exercise balls that ship with a hand or foot pump, the Wellrox comes with a powerful 150W electric pump that inflates your ball in just minutes so you can focus on your workout instead of wearing out your arms before it even begins. The pump features dedicated inflate and deflate ports, making storage a breeze when you need to pack it away. Constructed from thick, durable eco-friendly PVC with an anti-burst design, this ball is engineered for safety. If punctured, it deflates slowly rather than bursting, giving you peace of mind during intense core workouts, yoga flows, and balance training. The matte non-slip surface provides a secure grip on any floor and against your body, even during sweaty sessions. At 45-55cm (18-22 inches), this ball provides a versatile size for both exercise and sitting at your desk. Use it for yoga, Pilates, and balance training to strengthen your abdominals, back, glutes, and hips. Replace your office chair to engage your core and improve posture throughout the day. Trusted for physical therapy, rehabilitation, and pregnancy support. The stable surface provides confidence during recovery exercises, prenatal workouts, birthing preparation, and gentle stretching. Lightweight at just 2.6 lbs, it moves easily between your home gym, office, and therapy space. Available in Rose and Black to match your style. Package includes: 1 exercise ball, 1 electric pump (150W) with 52 inch cord, 3 nozzle attachments (S/M/L), 2 ball plugs, 2 plug removers, pump storage bag, and user manual.
