Gym Ball

SAVE 63% RRP £34.99

Build your core strength and balance with the Core Balance Anti-Burst Gym Ball. Because the inflatable ball is unstable to sit, lie or lean on, it constantly engages your core as your stabiliser muscles go into overdrive to help you maintain your balance.

Durable Anti-Burst Design

The inflatable gym ball is made from anti-burst PVC material for superior durability under pressure. Should it get punctured, it will slowly deflate rather than popping.

Anti-Slip For Greater Balance

Anti-slip lines around the perimeter of the ball provide superior grip. This stops it slipping and rolling under your weight, giving you greater confidence when you're working out.

Versatile Fitness Aid

Because you can sit, lie and lean on the ball, it's perfect for challenging your core whilst performing crunches and other exercises. You can also sit or lie on it when doing dumbbell exercises or use it as a prop to take yoga postures to a new level.

Get Fit Whilst You Sit

Even sitting on a gym ball engages your core which is why many people use gym balls as office chairs. If you wish to use your gym ball as a chair, we recommend buying a gym ball one size larger than you would for exercise. See our size guide below.

Includes Pump & Tape Measure

The gym ball includes a pump and a tape measure to easily inflate to the correct capacity. A spare stopper plug and a tool to remove the plug are also included.

Key Information

Durable Anti-Burst PVC

For safety during pregnancy, we've designed the ball using durable PVC. Not only is it free from phthalates and harmful chemicals, but it has an anti-burst design to slowly deflate if punctured.

Grippy Anti-Slip Lines

Worried that the exercise ball will roll away from underneath you? With its anti-slip lines, it's safe to use on smooth flooring. What's more, it provides excellent grip when sitting, lying, or leaning on it.

Pump & Tape Included

Inflating the ball to the correct capacity is easy using the pump and tape measure included. For best results, inflate it to 80% of its recommended size and leave it for 24 hours before finishing inflation.
