The Decathlon Domyos Durable Swiss Ball is the cheapest on test but is robust and grippy and backed up by the best guarantee…

The Decathlon Domyos Durable Swiss Ball may look cheap and plasticky (it certainly is cheap), but its shiny surface is surprisingly grippy, helped by a number of textured rings. It also boasts a two-year guarantee, which no other gym ball on test can match. So it’s a really handy and affordable piece of home gym equipment, and perhaps one of the best exercise balls.

Men’s Fitness verdict

It might be the cheapest on test but Decathlon’s ball comes with a two-year guarantee. It’s robust enough to withstand weight-based exercises and comes in three sizes too.
  • Excellent value
  • Good range of sizes
  • No pump included
  • Bright colours

How we test the best exercise balls

Our testers used each exercise ball as part of their day-to-day fitness routine for at least a month. They tested them during bodyweight workouts, resistance weight training and mobility work and judged them on their firmness, durability and comfort – taking price, maximum load, ease of inflation and colour/size options and accessories into account when awarding a final score.

Sizes:55cm / 21.7in, 65cm / 25.6in, 75cm / 29.5in
Pump included:No
Weight limit:130kg / 286lb
Colour:Peacock blue, damson

On closer inspection it feels thick and durable, and at 2kg it’s not the lightest. So it’s a surprise that Decathlon only recommends it for use with weights up to 286lb (130kg) – though it’s been shown to withstand up to 716lb (325kg). So the ball can certainly cope with various weight-based exercises.

Decathlon Domyos Durable Swiss Ball features

The Decathlon Domyos Durable Swiss Ball comes in three sizes – 55, 65 and 76cm – and Decathlon provides a handy chart to help you choose the right size based on your height and weight. Though it doesn’t supply a pump, you do get a tape, two plugs and plug remover, as well as a poster with nine exercises to get you started.

The two colours (turquoise and pink) may not be to everyone’s liking, but if you can forgive that you’re getting an excellent-value gym ball without having to compromise on size. As the cheapest on test, it’s ideally priced for beginners, but it’s backed up by the longest guarantee too – a win-win as far as we’re concerned.

With quick inflation and deflation times, it’s a good travel option too – though it is one of the bulkier balls when deflated.
