Gym Ball

SAVE 51% RRP £27.99

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

Core Balance Exercise Ball

A jack of all trades, our gym ball can be used for a multitude of exercises to improve your balance, strengthen your core, and tone your muscles. Plus, it doubles up as an office chair, or a birthing ball if you’re pregnant.

Anti-Slip for Optimum Grip

Sure, it’s big and round, but there’s no danger of our exercise ball rolling away from underneath you. The reason? Anti-slip lines which are specially designed to provide optimum grip if you’re working out on smooth flooring.

Durable Anti-Burst PVC

Because our exercise ball is made from anti-burst PVC, it will slowly deflate if it gets punctured rather than bursting with a bang. To eliminate the risk of puncture, always use it in a large space which is free from obstacles.

Free From Harmful Chemicals

We’ve tested our gym ball to ensure it’s free from phthalates, carcinogens, and other harmful chemicals. If you’re using it to alleviate pain during pregnancy or improve your comfort during labour, there’s no risk of harm to your baby.

250kg Load Capacity

With a weight capacity of 250kg (a whopping 30 stone), our exercise ball is one tough cookie. It also comes in a range of sizes to suit your height. If you’re wondering what size you need, check out our guide at the bottom of the page.

Pump & Tape Measure Included

All our exercise balls come with a hand pump and tape measure to easily inflate to the correct capacity. For best results, we suggest inflating it to 80% of its recommended size and leaving it 24 hours before finishing inflation.
