Kettlebell Buyer's Guide: One Bell, Hundreds of Exercises

What Is a Kettlebell?

A kettlebell is a cast iron or steel ball with a handle on top. Unlike dumbbells, the weight sits below your grip, which changes the dynamics of every exercise. Swings, cleans, snatches, and Turkish get-ups all exploit this offset centre of gravity to build explosive power, conditioning, and grip strength simultaneously.

There are two main types: cast iron (traditional, slightly wider handle, size varies with weight) and competition (steel shell, same dimensions regardless of weight, colour-coded). Cast iron is better for general training. Competition bells are better if you plan to do kettlebell sport or want consistent technique across weights.

Who Needs a Kettlebell?

Anyone who wants conditioning without a treadmill. A single kettlebell and ten minutes of swings will give you a more effective cardio session than 30 minutes of jogging. Kettlebells are also brilliant for people short on time — a 20-minute full-body session with one bell is genuinely enough.

They’re particularly popular with CrossFit athletes, martial artists, and anyone who wants functional strength that transfers to real life. Picking up heavy, awkward things is what kettlebells train you for.

What to Look For When Buying

Weight selection: Men typically start at 12-16kg. Women typically start at 8-12kg. For swings specifically, most people can handle heavier than they think — swings use your posterior chain, not your arms.

Handle finish: A smooth, powder-coated handle is ideal. Avoid painted handles (paint chips and gets slippery) and overly rough finishes (they’ll tear your hands). The handle should fit two hands comfortably for swings.

Base: A flat base is essential so the bell sits stable on the floor. Cheap bells sometimes have a rounded base that rolls.

Coating: Rubber-coated bells protect floors but are bulkier. Bare cast iron is the classic choice — just use a mat underneath.

Our Top Picks

1. Wolverson Fitness Kettlebell — £30-£70

UK-made and excellent quality. Smooth handle, flat base, clean casting with no rough seams. Available in every standard weight. The best all-round choice for UK buyers.

2. Mirafit Cast Iron Kettlebell — £20-£50

Great value and widely available. Solid build for the price. The handle finish is good but not quite as refined as Wolverson. Perfect for building a collection without breaking the bank.

3. Rogue Kettlebells — £40-£80

Premium build quality with a legendary handle finish. Rogue bells feel perfect in the hand. The downside is price and shipping to the UK, but if you want the best, this is it.

4. Decathlon Cast Iron Kettlebell — £15-£40

The budget option. Surprisingly decent for the price. The handle can be slightly rougher than premium brands, so consider sanding it lightly. Good for beginners testing the waters.

Starter Workout

If you’re new to kettlebells, learn the swing first. It’s the foundation of everything else. Start with 5 sets of 10 swings with 60 seconds rest. When that feels comfortable, add goblet squats and Turkish get-ups. Those three exercises alone cover your entire body.
