We've designed this innovative Swiss Ball for Pilates to improve your posture, strengthen your core muscles and work on your balance. Have you had enough of running after your ball? The weighted Swiss Ball is more convenient as it won't roll away after each exercise. Available in 3 sizes (S, M and L)


Versatility Stronger back, flatter tummy, Pilates... it can also be used as a seat.
Stability The Swiss Ball stabilises after each exercise thanks to the weighted base.
Compatibility The ball can be inflated/deflated with most pumps using the tips provided!

How do you choose a Swiss Ball during pregnancy?

You're expecting a little bundle of joy, but which Swiss ball should you choose?
You will need different ball sizes as your pregnancy progresses and you gain weight
As a safety precaution, and so that you don't have to buy multiple balls, we recommend choosing a ball that is one size bigger than you would normally need
It is essential that you follow the safety instructions to the letter so that you stay safe.

How to safely inflate your Swiss ball

We recommend using a pump, which is sold separately
Before inflating your ball, leave it at room temperature (20°C) for 24 hours
Inflate the ball slowly so it does not get damaged
Inflate the ball to 2/3 of its max size, at a temperature of between 20°C and 25°C max, then wait 2-3 hours
Finish inflating it to the desired size but do not go over the maximum size
Leave the ball for 24 hours before using it and check the size and adjust it if necessary

Why choose a Stable Swiss Ball?

We have made this Swiss Ball more accessible than a classic ball. It has a weighted base to prevent it from rolling away between exercises so you can maintain full concentration during your workout. It is also easier to store - pretty practical, don't you think?

Inflating your Swiss ball to the right size

Inflate your ball
Remove the pump's nozzle from the hole
Plug the hole with your finger, with the stopper in your other hand
Sit on the ball and adjust the size, then put the stopper in the hole
Intended for:
Pilates - when sitting on the ball your knees should be bent to 90° and at the same height as your hips, or slightly higher
Office - adjust the ball's height so that your elbows are at the same height as the top of your desk

"A very good product that really helped my sciatica. I first used this ball at my physiotherapist's to do exercises for my back and I saw immediate results. It relieves tension in the back and strengthens the abs very gently. Great value for money." Julien, Decathlon customer
