If you can’t find the answer you’re looking for, please contact our dedicated customer service experts, they’ll be happy to assist and provide the support you need

Are cast iron kettlebells better than competition steel ?

Depends on what you're training for. Cast iron has a wider handle than steel competition kettlebells, better suited to two-handed swings and goblet work.

While steel kettlebells stay the same size regardless of weight, cast iron increments grow as you get stronger, this is what levelling up feels like.

If you want that classic, rugged feel with more room for your grip, these cast iron kbells are perfect.

Can I lose weight and build muscles using cast iron kettlebells?

Exercises with cast-iron kettlebells fire up your entire body, from your glutes to your core. Every swing and lunge burns fat and supports weight loss. With proper progressive overload and increasing your workout intensity, you can lose that weight and fat while building pure muscle.

How do I maintain cast iron kettlebells to stop them from rusting?

Cast iron kettlebells are finished with a durable coating that resists chipping and rust, but simple cleaning and maintenance can help extend their lifespan. After each strength training session, wipe down the kettlebell to remove sweat. This keeps the professional finish looking sharp and ready for the next use. Store them in a dry place or on a kettlebell stand or rack. Following these simple steps helps prevent rust in your gym equipment.

What kettlebell weight should I start with as a beginner?

For beginners, start with an 8kg to 12kg kettlebell for women or a 10kg to 16kg kettlebell for men. Your goal is to master the form and the basic. Then you slowly increase the weight in progressing. Choosing a weight in this range ensures you can move with the necessary speed and explosiveness without putting a strain on your muscles.
