Competition Kettlebells

Our Competition Kettlebells Range

Factory Weights stocks competition kettlebells used in UK home gyms and commercial health clubs, where serious lifters push their limits for real results. Our experienced fitness team leverages extensive industry knowledge to ensure we offer the best on the market. 

Backed by a generous return policy, our heavy-duty gear lets you test the balance on your own gym floor, completely risk-free. Explore our professional, competition-grade kettlebells that deliver new personal bests every time.

Calibrated Kettlebell Construction

Unlike cheaper, sand-filled kettlebells, our high-quality competition kettlebells feature a hollow-core design that ensures accuracy, with every weight sized identically for maximum stability. These solid steel weights are expertly engineered to protect your movement patterns as you level up your lifting.

Calibrated to strict competition standards, exact technical specs include:

• 210 mm kettlebell width: Offers a consistent, uniform rack position against your forearm.
• 280 mm overall height: Ensures identical clearance and movement mechanics on every rep.  
• 150 mm base diameter: Creates a perfectly stable, unshakeable foundation on the floor.
• 200 g weight tolerance: Delivers precise calibration you can trust when pushing limits.

Ergonomic Handle

Our polished steel handle allows for better grip and control when building functional strength. Leaving the surface unsealed means the handle can hold gym chalk better than a completely sealed alternative.

These heavy-duty handle specs ensure a secure grip during high-rep exercises:

• 34 mm (+/- 1 mm) thickness: Fits comfortably in your palm to minimise grip fatigue.
• 55 mm clearance (+/-  2 mm): Provides ample space for smooth hand transitions mid-swing. 
• 198 mm external width: Delivers a balanced, professional profile for maximum control. 
• 123 mm internal width: Offers plenty of room for comfortable tracking during heavy cleans.

Maximum Stability

Moving an offset kettlebell requires significantly more core stability than training with standard dumbbells or barbell weights. The wide, flat base is designed to prevent rolling, keeping the kettlebell firmly planted between sets. This helps overall safety by reducing the risk of runaway weights during intense workouts. 

Pro tip:

• For accessory work, grab our smaller sizes.
• For explosive compound lifts, scale up to heavier weights.

Competition Kettlebell FAQs

Find answers to common questions about our competition kettlebells for sale.

What’s the difference between competition kettlebells & regular kettlebells? 

Regular kettlebells are made of cast iron, with sizes increasing as they get heavier. In contrast, the shape of competition kettlebells remains identical, with the same diameter across all weight options to meet strict international standards.

While a regular product focuses on everyday versatility, a standardised steel build ensures your handle diameter and body clearance never change. This gives athletes absolute consistency and precision during high-repetition training. Each competition tier is also colour-coded for easy identification, allowing you to select your weight quickly for safe, technical lifting.

What other types of kettlebells do you offer?

Beyond our competition kettlebells range, we sell standard, premium-grade kettlebells engineered to match your specific training style and space requirements. Ideal for meeting every fitness goal, our full kettlebell collection ensures your gym design has the exact tools needed for peak performance.

Other kettlebells in our list include:

• Pro-forged kettlebells: Crafted from solid iron with a sleek powder-coated finish, these feature a wide handle for maximum control during two-handed movements.
• Nexus adjustable kettlebells: Built with a solid steel handle and interchangeable plates, this robust, space-saving design adjusts from 3 kg to 32 kg, minimising clutter.

What are the best Kettlebell exercises for strength & endurance?

Kettlebell training is exceptionally effective for building strength, endurance and core stability through natural, full-body movement patterns. Unlike dumbbells that isolate specific muscles, kettlebells rely on momentum to challenge your entire body during high-intensity workouts.

The best exercises to smash your performance goals depend on your experience level:

• Beginner: Set a solid foundation and view proper form with goblet squats, deadlifts, and single-arm rows.
• Intermediate: Increase intensity with classic kettlebell swings, side lunges and curtsy squats.
• Advanced: Push your limits with high-skill snatches, Turkish get-ups, overhead squats and windmills.

How should I store & maintain competition kettlebells?

Competition steel has an exposed alloy handle, so oxygen and sweat from intense overhead press routines will cause rust over time. To keep your steel weights in good condition, strip any shipping varnish from a brand-new handle using a liquid varnish remover.

• Keep a fine-grit sandpaper sheet and a green scrub pad nearby to allow efficient removal of caked-on chalk or oxidation. 
• Throw a towel or hat over the bare steel handle if your gym setting is prone to dampness. 
• Take a moment to review and clean your weights after workouts to decrease rust buildup, so you can select a clean grip for your next lifting session.
