A compact inflatable exercise ball for Pilates, core training, balance and controlled mobility work, small enough to squeeze between the knees or hands or to sit on for stability drills. It is made from PVC and can be produced to an anti-burst specification, with standard or extra-thick walls depending on how much durability the programme needs. Firmness is set by how far the ball is inflated, so it can be softened for gentle work or firmed up for core and balance exercises. Size, wall thickness, surface finish, colour and printed logo are all made to order.Key details:Materials: PVC, anti-burst specification available
