nuobell dumbbells original green

A pair of NÜOBELLs

  • replaces up to 32 standard dumbbells
  • saves time and space
  • keeps your training fast, fun and fluid.

Durable and versatile

With its good looks and space-saving design, NÜOBELL dumbbell is the one piece of exercise equipment you’ll be happy to have at home.

When we started out, we loved working out with dumbbells, but to have enough weight options they took up too much space and, with their static design, lacked the fluidity that made the feeling of working out with free weights so attractive in the first place.

So we made something better.

The result? An adjustable dumbbell with revolutionary twist to choose all-in-one weights.

Any weight in an instant – and in the same dumbbell. That’s NÜOBELL.

As simple as it gets

One of the sweet spots with adjustable dumbbells is that they embrace simplicity; they are easy to use, require minimal setup and can be used for a wide range of exercises – and for any fitness level, from beginner to pro athlete.

So if you’re looking for a way to simplify your workout, without sacrificing results, adjustable dumbbells is the choice for you. Twist the handle to choose any weight – then go!

NÜO Athletic Innovation released FLEXBELL in 2016 and it was the first generation of our adjustable dumbbells. This mechanism allows 4 kg increments of the weights and has no half plates on the inside, like NÜOBELL. It also has an older handle mechanism meaning that all FLEXBELL and NÜOBELL products are different and not comparable.

Our patent is still active on FLEXBELL and we manufacture this model still, but only to a few selected resellers.

In 2020 we released the updated version of FLEXBELL: the NÜOBELL. NÜOBELL has 2 kg weigh increment, improved mechanism for safe use and offered in color variations.

You can still order the replacement handle if needed; go to the product page.
