Work with heavy loads using this 20kg cast iron weight. Sold individually, it is compatible with all 28mm bars and dumbbells.
Why use cast iron weights?
- Cast iron is more resistant to impacts, drops, and crushing (5 times better) than vinyl.
- Cast iron has a textured surface for excellent grip even when your hands are wet, unlike plastic, which can be slippery.
Choosing our cast iron weights means you can train with confidence and efficiency.
Our coach's workout with this 20kg weight
An idea for a back workout focusing on building muscle mass.
Short recovery between each set
- Pull-ups 3x8-10 reps
- Barbell row, pronated grip 3x8-10 reps
- Lumberjack row with dumbbell 3x8-10 reps/side
- Face pull with elastic band 3x12-15 reps
You can increase by one rep per week, starting from the lower end of the range. Always keep a two-rep margin.
Why choose cast iron over plastic or vinyl bumper plates?
- Cast iron is a dense material that is more compact than vinyl, meaning you can add more discs to the bar (up to 32kg on a 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 variety of conditions.

Our cast iron plates are made from at least 80% recycled cast iron
Since 2018, our teams have gradually integrated recycled materials until we reached the perfect balance. After 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 waste and steel - a true achievement for the world of metals! To ensure that the quality is the same as classic cast iron, tests are carried out in partner laboratories.
With disc collars, you can train safely!
Remember to invest in a pair of disc collars to prevent your weights from slipping on the bar while you train. Ours are sold as a pair (ref:8574652).
The maximum weight supported by the disc collars in a vertical position is 15kg.
Store your weight discs properly for long-term use
Store your discs indoors in a dry place. Invest in a disc rack (ref:8796727) or a storage rack (ref:8788246) to save floor space. The bottom of a piece of furniture can also store your weights. Feel free to clean them with a microfiber cloth if they get dusty.
