9-Inch Pilates & Yoga Exercise Ball for Core Workouts and Balance Training
Why We Recommend It
That dull lower back ache that keeps coming back no matter how many stretches you try? It's often a weak core — and this 9-inch ball is the tool physical therapists use to fix it. The THERABAND Mini Ball adds instability to standard moves like crunches and bridges, forcing your deep stabilizers to engage. It's not magic, but it's one of the simplest ways to make bodyweight exercises actually work your core. One honest limitation: at 9 inches, it's not for tall people doing full-body balance work — that's what a larger exercise ball is for.
What Makes It Stand Out
Strengthen your deep core without heavy weights
Place it under your lower back during crunches and feel muscles you didn't know existed engage.
Improve balance and stability anywhere
Use it between your knees or under one hand during planks to challenge your stabilizers.
Rehab safely at home
Physical therapists use this exact ball for post-surgery shoulder and hip strengthening — gentle enough for early recovery.
Pros & Cons
✓ What We Love
- Textured surface stays put on floors and walls — no slipping mid-exercise.
- Anti-burst PVC can handle up to 600+ lbs of pressure.
- Includes a 20-page exercise booklet with moves for abs, back, shoulders, and legs.
- Lightweight and portable — deflates flat for travel.
○ Worth Knowing
- Not suitable for sitting or full-body balance work — it's too small at 9 inches.
- Inflation tube is small and easy to misplace; keep it in the booklet sleeve.
