FAQs Of best gym ball for physical therapy

How do I choose the right size ball?

Match ball size to your height. A simple guide: 55cm for about 5’1″–5’7″, 65cm for about 5’8″–6’1″, 75cm for taller. Your hips should be level or slightly above knees when seated.

Are mini balls useful for therapy?

Yes. Mini balls target adductors, core, and shoulder control. They support the spine and help you learn proper breathing and alignment.

Can I use a ball as an office chair?

Short sessions can help posture and core awareness. Switch back to a regular chair as needed. Do not sit for hours at first.

What is anti-burst and why does it matter?

Anti-burst means the ball deflates slowly if punctured. It improves safety during rehab and strength moves.

How firm should my ball be?

Firm enough to keep its shape, but not rock-hard. You should feel stable with a little give for comfort.

Final Verdict: Which Should You Buy?

The Trideer 65cm Stability Ball is my top overall pick. It balances safety, comfort, and sizing, making it the best gym ball for physical therapy for most people.
