    Why should you use cast iron weights?

    - Cast iron better withstands shocks, drops and crushing (5 times better) than vinyl.
    - Cast iron has a textured surface for excellent grip even when your hands are damp, unlike plastic, which can be slippery.

    Choosing our cast iron weights means you can work out confidently and efficiently.

    Our cast iron plates are made from at least 80% recycled cast iron

    Since 2018, our teams have been gradually integrating recycled materials until we reached the perfect balance. Following several years of experiments, 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 real feat for the world of metal! To ensure that the quality is the same as classic cast iron, tests are carried out in partner laboratories.

    Our coach gives you some ideas for using your cast iron weights

    If you have a dumbbell bar, you can do a standing press with one or two dumbbells.

    Shoulder and triceps exercise:
    - Standing press, 4×8 to 10 reps

    At the end of your sets, try to have a 2 rep margin. Increase the number of reps and load as you improve.

    What weight training bars or dumbbells can be used with this 1 kg disc?

    This 1 kg weight can be used to load 28 mm bars, including the following:
    - 1.2 meter straight bar (ref: 8289897)
    - 1.2 meter curl bar (ref: 8484124)
    - 86 cm triceps bar (ref.: 8484125)
    - 35 cm short bar (ref.: 1041986)
    - 45 cm threaded bar (ref.: 8766096)
    - 1.55 meter straight bar (ref: 8289896)
    - 2 m straight bar (ref.: 8289900)
    50 mm bars will not be compatible with this weight.

    Why choose cast iron instead of plastic or vinyl bumper weights?

    - Cast iron is a dense material that is more compact than vinyl, which means you can add more discs to the bar (up to 32 kg on one dumbbell bar)
    - Cast iron lasts a lifetime, unlike plastic or vinyl, which can wear out within a year.
    - Cast iron is less affected by temperature changes so you can use it in a range of conditions.

    Keep your cast iron plates for longer by storing them correctly

    Cast iron weight training disc plates will virtually last forever if they're kept far from moisture.
    Store them in a dry place.
    Dust them with a damp cloth from time to time.
    Store them on your storage rack (ref: 8788246), a wall rack for plates (ref: 8796727) or on the bottom of a piece of furniture.

    Use disc collars to train safely

    It is essential to have a disc collar to secure weights on your bars or dumbbells. It prevents the weight from slipping during your exercises.
    Our Smart Disc Collars are sold in pairs, since you need 2 for one bar, or 4 if you train with 2 dumbbells (ref: 8574652).

    From extraction to production, metal has a high environmental footprint. To help reduce it, we use recycled metal in this product — sourced from recovered scrap, sorted, shredded, and melted down in electric furnaces, which are far less energy-intensive than traditional coal-fired blast furnaces. The result: the same performance as virgin metal, with a lower environmental impact: – 40% less energy used – 19% fewer CO2eq emissions – and fewer raw materials extracted
