This Bloom yoga ball comes in two sizes: 55cm in grey or 65cm in black. It’s made for heavier use than a standard home ball, with a thickened wall, and it’s a good choice for studios, gyms and anyone buying a set.
The PVC resists compression and abrasion, and the frosted finish gives good grip. It’s anti-burst: if it’s punctured, it deflates slowly instead of bursting.

Which size
Pick by height. The 55cm grey ball suits people about 140cm to 165cm tall, and the 65cm black ball suits about 165cm to 185cm. Studios buying several usually get a mix so students of different heights can sit with their hips level with or a little above their knees.

| 165cm to 185cm | 65cm ball |
| 185cm to 195cm | 75cm ball |
For people over 185cm, look at the Bloom anti-burst yoga ball in 75cm. Our Swiss ball size guide covers sizing in more detail.
How to use it
Use it for the usual Swiss ball work: seated balance, planks and crunches over the ball, bridges with your heels on it, and back stretches lying over it. The thicker wall makes it a sensible pick where lots of different people use the same balls. At 1.2kg and 1.4kg, they’re easy to lift onto a rack or carry between rooms.
Care
Inflate it in two stages over a day and check it against a mark on the wall. Wipe it down with a damp cloth and mild soap between classes. Keep balls away from heaters and strong sun, and store them off rough concrete.
