For PT and light core work the size and softness deliver, but plan on a standard pump needle if the included straw gives trouble sealing it.

Overview
A 9-inch (23cm) soft PVC exercise ball that ships deflated, intended for core work, Pilates and physical therapy exercises where a small ball provides light resistance or balance.
The one recurring hiccup is inflation: the included straw inflator lets air escape while you swap in the plug, and more than one reviewer solved it by using a standard pump needle instead.
- 9 inch (23cm) diameter
- Ships deflated in clinical packaging
- Soft rubber PVC surface
- Includes plug and straw inflator
Who it's for
Suits people doing physical therapy exercises at home, or Pilates and core work needing a small, soft ball between the knees or against a wall. Less suited to anyone who wants foolproof inflation with the included tools alone.
Pros and cons
- Compact, soft size suits PT and core exercises
- Holds air well once sealed
- Gentle surface for post-surgical rehab work
- Included straw inflator makes sealing tricky
- No valve, so air can escape during setup
