Kettlebells

One piece of cast iron, no seams, no moving parts. The single-cast kettlebell is the format that survives being dropped on concrete a thousand times, which is precisely what serious swing and snatch training involves.

KEY FEATURES

Single-piece cast iron construction with no welds or joints
Wide smooth handle suited to two-handed swings
Flat machined base sits stable for renegade rows and push-ups
Consistent centre of mass for predictable ballistic work
Durable finish resists chipping and rust
Available across a graded weight range

PRODUCT OVERVIEW

Single-cast construction is the specification that matters. A kettlebell made in one pour has no seam between handle and bell, which means no weak point at the horn where the entire load concentrates during a swing. Two-piece or welded bells exist and are cheaper, but the handle junction is where they eventually fail.

Handle geometry is the second consideration. A wide handle accommodates two hands for swings, and a smooth finish prevents the tearing that knurling causes during high-repetition snatch work. The flat base matters more than people expect, since it is what allows the bell to be used as a stable platform for renegade rows, push-ups and get-up transitions.

TRAINING APPLICATION

Cast iron kettlebells cover the full repertoire: two-handed swings, single-arm swings, cleans, presses, snatches, jerks, goblet squats, Turkish get-ups, windmills and loaded carries. The ballistic movements in particular are what kettlebells do better than any other implement, training hip extension power and grip endurance simultaneously in a way dumbbells cannot replicate.

HOW TO CHOOSE?

Choose fixed cast iron if you know your working weights and train ballistically. A swing takes more weight than a press or a get-up, so most people end up with at least two bells rather than one. Pick the swing bell by feel: it is right when ten hard repetitions leave your hips, not your arms, doing the work, and add a lighter bell for overhead and get-up work. Choose an adjustable kettlebell if space or budget rules out multiple bells. Add a rack early, as loose kettlebells on a floor are a genuine hazard.

FAQs

What weight kettlebell should I start with?

A swing bell is right when ten hard repetitions leave your hips, not your arms, doing the work; overhead and get-up work takes a lighter bell than swings do. Adjust to your own strength and experience.

Why is single-cast construction better?

There is no seam or weld at the handle junction, which is where the load concentrates during a swing and where cheaper two-piece bells eventually fail.

Should the handle be knurled?

A smooth or lightly textured handle is preferable for high-repetition snatch work, since aggressive knurling tears the hands.

Can I use kettlebells on a wooden floor?

With matting, yes. Cast iron on bare timber will mark it, and dropped bells will damage it. Interlocking foam or rubber tiles are strongly advised.

Questions & answers

What weight kettlebell should I start with?

There is no single right first bell, so choose by the lifts you intend to practise. Swings and goblet squats take the heaviest bell you can control for full sets with a flat back; presses, Turkish get-ups and windmills take a noticeably lighter one. Cast Iron Kettlebells are sold as singles from 2 kg to 40 kg, so you can buy one bell for each job and add to the pair of them as your practice develops.

Which weights are available, and is the price per kettlebell?

Yes, each Single Kettlebell option is one bell. Cast Iron Kettlebells come in 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24, 28, 32, 36 and 40 kg, with the price rising as the weight rises. The 4 kg is currently out of stock, with notify-me available. Select a weight and its current price is shown beside it.

How big are the kettlebells and handles?

Cast Iron Kettlebell handles grow with weight: 28 mm thick and 120 mm wide at 4 kg, 34 mm and 150 mm at 12 kg, 35 mm and 160 mm at 16 kg, 37 mm and 178 mm at 24 kg, 38 mm and 190 mm at 32 kg. Height: 165 mm at 4 kg, 320 mm at 32 kg.

Are these single-cast, and is the handle knurled?

Yes, each Cast Iron Kettlebell is cast in one piece with no weld at the handle, the junction where the product page says two-piece bells eventually fail. The handle is smooth with a light powder-coated texture rather than knurled, which the page prefers for high-repetition snatch work. A flat machined base keeps it stable for rows.

How do I look after cast iron kettlebells?

The powder-coated finish on Cast Iron Kettlebells resists chipping and rust, and the flat base stores them upright. Use rubber or EVA matting on timber or laminate, since cast iron on bare boards will mark them and a dropped bell will damage them. Store bells on a rack rather than loose on the floor.

Which rack fits cast iron kettlebells?

The Commercial Kettlebell Half Rack, 61 × 52 × 54 cm, suits a wall-side studio set; the Commercial 2-Tier Kettlebell Rack, about 140 cm long, suits a home or class set. Three Cast Iron Kettlebell set options include a rack. No capacity in kilograms is published, so put the heaviest bells on the bottom tier. Each rack shows its current price on its own page.

How much is delivery on cast iron kettlebells?

Free delivery to every address in Great Britain, including the Scottish Highlands and Islands. Cast Iron Kettlebells are on the heavy-item profile, so Northern Ireland is priced by weight at checkout on the heavy single box rate. Order by 2pm Monday to Friday for same-working-day dispatch; standard delivery takes 2 to 5 working days after dispatch.

Can I return a kettlebell?

Yes, within 180 days of delivery if the Cast Iron Kettlebell is unused and in its original packaging, with no restocking fee. You pay return postage unless the bell is faulty or incorrect, when the return is free; original delivery charges are not refunded. Faults are covered by your statutory rights under the Consumer Rights Act 2015.

What kettlebells do you sell and in which weights?

Cast iron kettlebells are sold singly in 15 weights from 2 kg to 40 kg (2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24, 28, 32, 36 and 40 kg) and as graded sets of 3 to 7 kettlebells covering 4 kg to 32 kg, with or without a storage rack. There is also an 18 kg adjustable kettlebell. Optional kettlebell racks (a commercial half rack and a 2-tier rack) are offered on both listings.

What size kettlebell should a beginner buy?

Choose by the lift rather than by a single first bell. Swings and goblet squats take a heavier bell than presses, Turkish get-ups and windmills, so two bells cover more of the work than one. Lift Sets cast iron kettlebells run from 2 kg to 40 kg and are sold singly, so you can buy one at a time and add to it. A bell is the right size for a lift when you can finish full sets with your technique intact.

Which cast iron kettlebell set should I buy?

Sets run from A (4, 6 and 8 kg, 18 kg total) through D (4 to 12 kg, five bells) and F (4 to 20 kg, seven bells) to I (18, 20, 24, 28 and 32 kg, 122 kg total); G (10 to 24 kg) and H (12 to 28 kg) suit someone who already swings 16 kg. Pick the set whose heaviest bell is your swing weight and whose lightest is your press or get-up weight, and add a rack early because loose bells on a floor are a hazard.

Which weights are in the kettlebell sets?

Set A is 4, 6 and 8 kg (18 kg); B adds 10 kg (28 kg); C is 6 to 12 kg (36 kg); D is 4 to 12 kg (40 kg); E is 4 to 14 kg (54 kg); F is 4, 6, 8, 10, 12, 18 and 20 kg (78 kg); G is 10, 12, 18, 20 and 24 kg (84 kg); H is 12, 18, 20, 24 and 28 kg (102 kg); I is 18, 20, 24, 28 and 32 kg (122 kg). Sets are sold on the Cast Iron Kettlebell Sets page.

Is the base flat?

Yes. The base is machined flat so the bell sits stable for renegade rows, push-ups and get-up transitions and stores upright between sets.

What is the heaviest kettlebell you sell?

40 kg. The single cast iron range runs 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 24, 28, 32, 36 and 40 kg, each sold as one bell.

Can I use kettlebells on a wooden floor?

With matting, yes. Cast iron on bare timber will mark it and a dropped bell will damage it, so put interlocking foam or rubber tiles under the training area.

What exercises are cast iron kettlebells for?

Two-handed and single-arm swings, cleans, presses, snatches, jerks, goblet squats, Turkish get-ups, windmills and loaded carries. The ballistic lifts train hip extension power and grip endurance together in a way dumbbells cannot replicate.

What finish do the kettlebells have?

A durable matte finish over single-piece cast iron that resists chipping and rust, with a smooth, wide handle. Wipe the handle after use and store it dry; rust from wet storage is a warranty exclusion.
