Overview
A small 7 to 8 inch Pilates and core ball made from anti-burst PVC, sized for a single-handed grip and sold with its own pump for inflation.
Small stability balls like this are common in physical therapy for knee squeezes and core work precisely because the compact size fits between the knees or in one hand where a full-size ball would not. The listing notes a break-in period in the first week where the ball may need a top-up of air as the PVC settles.
- 7-8 inch diameter
- Anti-burst PVC construction
- Pump included
- One week break-in period
Who it's for
Fits anyone doing Pilates, barre, physical therapy exercises, or knee-squeeze core work at home, including chair or wheelchair-based routines. Not sized for full-body stability ball exercises that need a larger diameter.
Pros and cons
- Fits comfortably in one hand or between knees
- Includes a pump for inflation
- Non-slip surface holds during exercises
- May need occasional reinflation between uses
- Initial inflation is a bit stiff with the included pump
