Care and safe use

  • Put each dumbbell back in its base before you change the weight, and check the selector has clicked into place before you lift.
  • Lower the dumbbells under control. Do not drop or throw them, as this can damage the plates and the selector.
  • Wipe the handles after use and store the set indoors, away from damp and direct heat.
  • Stop using the set if a plate is loose or the selector does not lock, and contact us.
  • Follow the instructions supplied with your model.

Are adjustable dumbbells worth it?

Yes. Adjustable dumbbells are an excellent investment for most home gyms. They replace multiple pairs of fixed dumbbells, saving both space and money while allowing you to progressively increase the weight as you get stronger. For most people, they’re the most practical choice for home strength training.

What weight adjustable dumbbells should I buy?

It depends on your experience and training goals.

  • Beginners: up to 24kg per dumbbell
  • Intermediate lifters: up to 32kg
  • Advanced lifters: 40kg or more

Choosing a heavier weight range means your dumbbells can continue to support your progress for years.
