Description
This 25cm purple pilates ball is a soft, small-diameter exercise ball made from gym grade PVC, supplied with an inflation straw, priced at $17.99 with fast Australian shipping. It is the size used in reformer classes, barre and physio programmes - squeezed between the knees, pressed against a wall, or placed under the lower back - rather than the large ball you sit on.
The small ball is doing something the big one cannot. A 65cm ball asks you to balance; a 25cm ball asks you to squeeze, and that squeeze is what switches on the inner thighs, the pelvic floor and the deep abdominals that a normal crunch skips entirely. It is why almost every clinical pilates studio has a bucket of them by the door, and why a physio hands one over after a knee or hip programme. Deflate it slightly and it becomes a wedge for lower back support instead.

What Is a 25cm Pilates Ball Used For?
Four main things. Squeezed between the knees or ankles during bridges, roll-ups and leg lifts, it adds adductor and pelvic floor engagement. Placed under the lower back or sacrum, it supports the spine through mat work. Pressed between your hands or against a wall, it turns upper body exercises into isometric holds. And part-inflated behind the lower back in a chair, it becomes a lumbar cushion. It is also a common tool in post-natal and post-surgical rehabilitation programmes prescribed by a physiotherapist.
Is a 25cm Ball the Same as a Birthing Ball?
No, and this is worth being clear about before you order. A birthing ball is a large stability ball, typically 65 to 75cm, that you sit on to open the hips during labour. This is a 25cm ball - it will not support body weight for sitting and is not a substitute. Small balls are used in pregnancy and post-natal programmes for pelvic floor and inner thigh work, but that is a different job. If you want something to sit on, you want the large size.
How Firm Should You Inflate a Mini Exercise Ball?
Less than you would expect. Inflate through the straw until the ball holds its shape but still gives noticeably when you press it with a flat hand - it should compress a couple of centimetres without effort. Overinflating is the most common mistake: a rock-hard ball is uncomfortable under the spine, hard to squeeze usefully, and puts unnecessary stress on the seam. For lower back support, let a little more air out again. You can adjust it any time by pulling the plug.
Buyers are typically people following a pilates or barre programme at home, physio patients working through a prescribed rehab plan, dancers, and desk workers who want something for lumbar support that packs away. It also gets bought as a low-cost addition to an existing home gym where the large ball is already taking up floor space.

Frequently Asked Questions
Does it come inflated?
No. It ships deflated with a straw so it packs small, and you inflate it by mouth in under a minute.
Can I sit on it?
No. At 25cm it is not a seating or stability ball and will not support body weight that way.
What weight can it take?
Our supplier does not publish a load rating, so we do not quote one. Use it for squeezing, support and pressing rather than standing or bearing weight on it.
How do I let air out?
Pull the plug out with a fingernail or the straw, press gently, and reseal. Adjusting firmness takes seconds.
Will it slip on floorboards?
PVC has some grip but it is a ball. Use it on a mat or carpet for wall and floor work.
How do I clean it?
Wipe with a damp cloth and mild soap, then dry. Avoid solvents and harsh cleaners, which degrade PVC.
Is it suitable during pregnancy?
Small balls appear in many pregnancy and post-natal programmes, but speak to your midwife, doctor or physiotherapist before starting any exercise while pregnant.
