Why choose a cast iron weight rather than plastic or vinyl?

- Cast iron, due to its density, offers superior compactness to vinyl, which allows for an increase in the number of discs on the bar (up to 32 kg on a dumbbell) - Cast iron can be kept for life, unlike plastic or vinyl ones which can last less than 1 year. - Less affected by temperature variations, cast iron offers constant use in different climatic conditions.

Our cast iron discs are produced from at least 80% recycled cast iron

Since 2018, our teams have gradually integrated recycled materials until they have achieved the best compromise. After several years of experimentation, Decathlon is replacing its entire range of cast iron products with recycled cast iron made from at least 80% scrap metal and steel waste—a feat in the metal world! To guarantee quality equivalent to conventional cast iron, tests are carried out in partner laboratories.

Why use cast iron weights?

- Cast iron is more resistant to shocks, falls and crushing (5 times more) than vinyl. - Cast iron has a textured surface ensuring excellent grip and traction, even with wet hands, unlike plastic, which is often slippery. Choosing our cast iron weights means choosing efficiency and reliability in your training.

Store your discs properly to use them for a long time
