I’ve never used adjustable dumbbells before, how do I adjust the weight?

Simply turn each adjustment dial to the weight you'd like. You will know you have fully and correctly selected the number when you hear a clicking noise. Ensure the weights are the same on each side of the handle before pulling out.

I’ve never used adjustable kettlebells before, how do I adjust the weights?

The adjustable kettlebells have a very simple lock and unlock mechanism when adjusting the weight. Simply pull the tab, slide to unlock and then remove / add the relevant plates to set your weight. Once the weight is set, slide the tab back to lock and you’re good to use your adjustable kettlebell.

What is the best practice to use the adjustable dumbbells?

As with all things mechanical you do advise to be sensible when using our adjustable dumbbells. We suggest to always lay down gently and never be dropped. We also suggest using a soft mat to place the dumbbells upon in between sets. Our Yoga Mat is a good option for this.

Are the dumbbells / kettlebells easy to use?

The dumbbells and kettlebells are both very easy to use. They come fully assembled and you can start using them straight away.

How durable are the dumbbells / kettlebells?

With a steel handle and a strength-enhancing plastic coating around the plates, the weight plates do not wobble and the dumbbell is firm in the hand. It feels like one solid piece. We do recommend taking care of your equipment and avoiding dropping them from a large height or using excessive force.

What are the weight increments?

These vary depending on the product and can be found on each product page.
