Choose cast iron plates rather than plastic or vinyl!
We'll explain why:
Because cast iron is more dense than vinyl, you can increase the number of discs on the bar (up to 32 kg on a single dumbbell, for example), which makes it easier to adjust your load and vary your exercises. Unlike plastic or vinyl weights, cast iron can last a lifetime.
What are the differences compared to vinyl and plastic?
- Cast iron is less sensitive to temperature variations, ensuring consistent use in different environments.
- Compared to vinyl, cast iron is much more resistant to impacts, falls, and crushing, offering up to five times more durability.
- Its textured surface provides an excellent grip even when your hands are damp, unlike plastic which tends to slip.
How many kilos (max) can you add to the dumbbells?
These dumbbells can hold up to 30 kg each. Because the bars and collars weigh 2 kg, each dumbbell can weigh up to 32 kg, or 64 kg for both.
If you are looking for weight to add onto your dumbbells, our 28 mm cast iron weight training plates are the perfect choice. From 0.5, 1, 2, 5, 10 to 20 kg, you're sure to find the exact weight you need.
Train safely with this dumbbell set
The weights attach to the threaded bar with a collar. They secure the plates tightly onto the bar, even when holding them vertically. If you do dynamic training, make sure to check the tightness of the collars between 2 sets or if you hear the plates bang together.
That being said, a little bit of play is normal for ensuring the plates can easily go on the bar.
Easy-to-store dumbbells
This dumbbell set is a great option if you want to put your equipment away after training. Just pack your dumbbells and weight in their case and slip them under your bed or in a cabinet.
Easily transport your entire set in its case.
Caring for your dumbbell set
Follow a few easy steps to make your dumbbell set last as long as possible.
Before storing your equipment in its case, wipe your dumbbell and weights with a damp cloth.
Then put the various parts of the set back into the slots provided in the case.
Store the case in a dry spot.
Moisture is your set's greatest enemy: never store it in a basement or outdoors.

MetalRecycled cast iron
Product made from 72% recycled cast iron
From extraction to production, metal has a significant environmental footprint. That’s why we use recycled metal in this product. Instead of extracting new resources, we recover and recycle metal waste. After sorting, cleaning, and crushing, the metal is remelted in electric furnaces — which use far less energy than traditional coal-fired blast furnaces. The result: fewer raw materials extracted, up to 40% less energy consumed, and at least 19% fewer CO2 emissions compared to virgin metal — with no compromise on performance.
