Quite annoying to blow up

So I bought this ball at decathlon in Leeds and I thought it would be very simple to assemble. I thought! I tried to blow it up but the pump adapters would not connect well at all and wouldn't come out. I tried every pump in the house but only 1 worked! I ended up having to blow it up by MOUTH ! The product is good but assembling it is the worst and instructions are totally useless.

Gym ball

Additional Product Information


Structure: 100.0% Polyvinyl Chloride

Which size swiss ball do you need?

Picking the right size is easy: if you're less than 1.60 m tall and weigh less than 85 kg, choose size 1 (diameter: 55 cm); if you're between 1.60 and 1.80 m tall and weigh less than 85 kg, choose size 2 (diameter: 65 cm); if you're more than 1.70 m tall and weigh more than 85 kg, then size 3 (diameter:75 cm) is the one you need.

How to inflate your gym ball to a safe size

First things first: we recommend using a pump, which is sold separately (product ref 8214626 or 8490986). Fully inflate your gym ball using a tape measure to check the diameter. As a guide, here are the maximum diameters of our different gym balls: Size 1 = 55 cm, Size 2 = 65 cm and Size 3 = 75 cm. Lastly, sit on the ball and check that your knees are at hip height. If they aren't, add or remove some of the air.

Which accessories does the swiss ball come with?

Your Swiss ball comes with: a plug, plus a second one in case you misplace the first; a plug remover to easily remove the plug when you want to inflate/deflate the ball; a tape measure to make sure you've inflated your ball to the correct size; a user guide; and a poster with exercises. And don't forget that you can download the instructions here:$162a572dc90bddf980d25188afc001eb/8603633%208603634%208603635%208640038%208

I don't know which exercises to do. have you got any tips?

We've got loads of ideas for you! Just copy and paste the link below into your internet browser:$cb1af4a5efa477ea4606585f44e5ef7b/poster%20definitif%20pixl.pdfIt's a free poster that you can download onto your smartphone and easily print out. It has been developed in collaboration with qualified coaches and contains a dozen or so exercises that you can do with your Swiss ball.

Ball weight

2 kg.

What should you do if you lose both your gym ball plugs?

Don't worry!This year, we're offering the option to buy plugs as spare parts from our stores' workshops.;)

Is our gym ball suitable for office use?

Our ball is designed for sports use but can also be used in the office provided you put a protective cover on it.

Product testing

To guarantee quality and safety, we perform numerous tests before our balls hit the shelves.There are two main tests. First up, we perform a compression test that involves compressing the ball more than 100,000 times with a 195 kg weight; we then perform a static compression test in which a 325 kg weight is placed on the ball.

Storage instructions

We recommend storing your Swiss ball in a clean, dry place at room temperature, away from heat sources (radiators, underfloor heating, sunny windows); also avoid lacquered or varnished surfaces, etc.
