Maximum Grip & Stability

A comfortable grip makes transitions between explosive kettlebell sets seamless. The Factory Weights pro-forged kettlebell features a spacious, easy-grip handle that keeps high-rep kettlebell workouts secure, even when your hands are slick with sweat.

Each bell is crafted from solid cast iron with a durable, powder-coated matte black finish, ensuring gym chalk sticks to the iron. Their wide, flat base delivers rock-solid stability on the gym floor, meaning they will never roll away.

Our kettlebell sizes range from 4 kg to 32 kg to work different muscle groups, then scale your resistance as your strength builds. Every weight option features our Factory Weights logo and a clear kg indicator stamped clean on the front, letting you spot your gear instantly during fast-paced circuits.

Cast-Iron Kettlebell FAQs

Find answers to common questions about our cast-iron kettlebells for sale.

What are the best kettlebell exercises for building full-body strength?

Exploring a range of different sizes ensures your grip never fails before your willpower does. Get the most out of your body by mixing explosive compound movements with targeted isolation work across your varied kettlebell training exercises: 

• Lower body power: Hammer your legs, glutes and lower back with heavy two-handed kettlebell swings and goblet squats.
• Upper body strength: Drive muscle growth across your shoulders and back with dynamic cleans, overhead presses and high-stability renegade rows.
• Targeted conditioning: Use technically straightforward movements like bicep curls and lateral raises, each easy to master and perfect for isolating specific muscles.

What fitness gear complements kettlebell training?

While kettlebells deliver explosive full-body power all on their own, adding targeted fitness tools can supercharge your conditioning and isolate specific muscle groups. By expanding your layout with high-yield fitness equipment, you can increase the resistance and unlock explosive new ways to test your power.

Lock in your progress with these high-performance strength training accessories:

• Battle ropes: Hammer your grip and torch your upper body by running a heavy conditioning rope directly through the handle window of your iron weights.
• Slam balls: Force your core and upper body to work overtime by aggressively driving a zero-bounce conditioning ball straight into the floor.
• Plyo jump box: Build serious leg drive and lower-body power by stepping or jumping onto a rock-solid, stable platform while holding extra weight.
• Weighted vest: Add hands-free, scalable resistance to your standard exercises and core drills without shifting, bouncing or restricting your natural training movements.

What other types of kettlebells do you offer?

Being named ‘Scottish Fitness Website of the Year 2022’ at the Scottish Health & Fitness Awards means we know exactly what works on every gym floor. We look beyond classic cast iron to offer specialised alternatives engineered to handle your toughest exercises:

• Competition kettlebells: Lock in flawless lifting mechanics using identically sized, hollow-core steel weights calibrated within 200 grams for absolute precision.
• Nexus adjustable kettlebells: House an entire weight range in a single solid-steel footprint by linking compatible plates to instantly scale your resistance.
