Best kettlebells to buy right now
One cast iron kettlebell does more than most home gym kit: swings, squats, presses and carries, all in a corner of a room. Start with 12kg for women and 16kg for men if you are new to it. An adjustable kettlebell saves space but the handle is wider and the weight shifts, so buy fixed bells if you plan to swing heavy.

Best for most people
1. Amazon Basics Cast-Iron Kettlebell 10kg
Textured, wide · 10 kg · Cast iron, painted
A plain cast iron bell from Amazon's own brand and one of the biggest sellers here, with a textured wide handle for one or two hands. This listing is the 10kg; 12kg suits most women and 16kg most men starting out, so check the other weights. The finish is paint rather than powder coat, which can chip if it is dropped.

Widest weight range
2. NORTHERN Cast Iron Kettlebell
Flat · 2 to 28 kg · Cast iron
A no-name cast iron bell sold from 2kg to 28kg, so you can buy the next weight up in the same shape. The listing quotes a rust and chip-resistant finish, a flat base and colour bands for each weight. It names no coating type, and the brand on the listing differs from the name on the bell.

Best UK brand

Best starter set
4. KK Neoprene Kettlebell Set 2, 4 and 6kg
2, 4 and 6 kg · Flat · Cast iron, neoprene coated
Three light, neoprene-coated cast iron bells from a no-name brand, for beginners, rehab work or toning circuits. The listing quotes textured handles and flat bases for upright storage. The set tops out at 6kg, too light for swings for most adults, so treat it as a starter.

Best competition bell
5. Rival Strength Competition Kettlebell
Same size at every weight · Non-slip · 4 to 32 kg
A competition bell stays the same size at every weight, so your technique does not change as you move up. The listing quotes weights from 4kg to 32kg, a non-slip handle and a colour for each weight. This listing is the 12kg, and at light weights a competition bell is bulkier than a cast iron one.

Best adjustable
6. BowFlex SelectTech 840 Adjustable Kettlebell
3.5 to 18 kg · Dial · 6 weights
Six kettlebells in one, set with a dial between 3.5kg and 18kg according to the listing, which saves a lot of floor space in a small flat. The listing quotes an ergonomic handle moulded around the plates. Like most adjustable bells, the body is bulkier than a fixed bell of the same weight, so it suits presses and goblet squats better than heavy swings.

Best budget adjustable
7. LIFERUN 7-in-1 Adjustable Kettlebell
ABS with aluminium handle · 2 to 20 kg · 7 weights
A no-name adjustable bell with seven settings from 2kg to 20kg, a die-cast aluminium handle and a safety lock. The listing admits the plates clink slightly by design, and a plastic ABS body will not take drops the way cast iron does. It costs less than the BowFlex, but it is a newer product from a little-known brand.
Nothing matches those filters. Try fewer filters, or search for a brand like "MSI" or "Crucial".
How we rank
Ordered by how well each sells in its Amazon UK category, what the listing confirms (fit, materials, sizes, features), and price. We have not handled these products: the write-ups rest on what each listing states. Prices and stock are checked daily.
Prices are Amazon UK and eBay UK at the time we last checked; they move daily, so confirm on the retailer's page. We earn a small commission if you buy through our links, at no cost to you. It never changes the order. More about how we work.
