Core Balance

Why we love it

Wide range of sizes.
Improves core strength.
Durable anti-burst material.

Main Highlights

RANGE OF SIZES FOR A PERFECT WORKOUT: Core Balance Gym Balls come in a choice of sizes to suit your height and workout in comfort. Check out our size guide (image 5) to determine whether you need a 45cm, 55cm, 65cm, 75cm, or 85cm ball. As an added bonus, each gym ball includes a pump and tape measure to easily inflate to the correct capacity.
DEVELOP YOUR CORE STRENGTH & BALANCE: By creating instability when you sit, lie, or lean on it, a gym ball forces you to engage your core muscles in order to maintain your stability. As well as strengthening your core and improving your balance, a gym ball workout is a winning way to tone your muscles, develop your posture, and improve your flexibility.
NO DANGER OF BURSTING OR SLIPPING: Because Core Balance Gym Balls are made from durable anti-burst PVC, there’s no danger of them bursting if they get punctured. Instead, they’ll slowly deflate to ensure your safety. In addition, the gym balls are covered in anti-slip lines to provide optimum grip on smooth flooring and prevent them sliding around.
TAKE YOUR WORKOUT TO A NEW LEVEL: Gym balls are a versatile fitness aid which can be easily incorporated into a wide range of exercises, including crunches, bridges, dumbbell workouts, yoga, Pilates, and more. As well as targeting the usual muscles, adding instability to exercises has the added benefit of giving your core stabiliser muscles a serious workout.
USE AS A CHAIR OR BIRTHING BALL: If you sit at a desk all day, you can use a gym ball as a chair to improve your core strength and balance while sitting. Plus, you can use a gym ball as a birthing ball for prenatal exercises, and to reduce discomfort during pregnancy and labour. Physios also use gym balls to help people rebuild their core strength after injury.

Main Highlights

55CM PURPLE PREGNANCY BALL: Our Purple Birthing Ball is perfect for pre-natal exercises and reducing pain and discomfort during pregnancy and labour. Made from durable anti-burst material, it has a weight capacity of 250kg (39 stone) and a diameter of 55cm when inflated, making it an ideal size for women measuring 5’ 4” tall and under.
BABY FRIENDLY ANTI-BURST MATERIAL: The birthing ball is made from durable anti-burst PVC. If it gets punctured, it will slowly deflate rather than bursting, making it safe to use when pregnant. The PVC material is free from Phthalates, carcinogens, and other short-chain chlorinated paraffins (SCCPs) which can be harmful to your baby during pregnancy.
COMFORTABLE NON-SLIP SURFACE: Anti-slip lines around the perimeter of the ball prevent it sliding out from underneath you when using it to alleviate the pressure on your pelvis, lower back, and spine during pregnancy, or to enhance your comfort during labour. It’s also an essential feature if you’re using it for pre-natal exercises to prepare you for birth.
PUMP & TAPE MEASURE FOR EASY INFLATION: The birthing ball includes a hand pump and tape measure to easily inflate it to the correct capacity. To get the best out of the birthing ball, we recommend inflating it to 80% of its recommended size and leaving it for 24 hours before finishing inflation. A spare plug and plug removal tool are included for easy deflation.
USING YOUR BIRTHING BALL: Sitting on a chair or sofa can feel uncomfortable during pregnancy, but a birthing ball distributes your weight to alleviate pressure on your back and pelvis. During labour, it can ease discomfort and open up the pelvis and hips to prepare you for birth. It’s also perfect for practising post-natal exercises to help you recover after birth.
