Overview
This 9 inch Pilates ball from ProBody is a compact inflatable prop for core work, barre, and physical therapy rather than a full-size stability ball. It ships with an inflation straw and inflates in seconds, sized to squeeze between the knees or support the lower back.
At 9 inches, this ball is a compact stability prop rather than a full-size ball meant for sitting or bouncing. It is meant to add light resistance to targeted movements like knee squeezes, bridges, or seated core work, not to bear body weight the way a 55-65 cm exercise ball does. The included straw makes reinflation simple if it loses air over time.
- 9 inch diameter
- Anti-burst material
- Includes inflation straw
- Textured grip surface
Who it's for
Suited to anyone doing barre, Pilates, or physical therapy exercises that call for a small squeeze ball between the knees or under the lower back. Not a fit for anyone looking for a full-size ball to sit or bounce on.
Pros and cons
- Compact size fits between knees for targeted core work
- Inflates in seconds with included straw
- Textured surface aids grip during barre or yoga
- Too small to use as a seated stability ball
Performance notes
Squeezed between the knees or tucked under the lower back, the 9 inch size activates targeted core muscles rather than supporting full body weight the way a larger stability ball does. It inflates in seconds with the included straw, and the material is described as anti-burst with a textured surface for grip during barre or yoga poses.
