Want one piece of kit that builds strength, burns fat, and fits in a spare corner? These cast iron kettlebells do all of that. Sizes run from 2kg right up to 40kg, so whether you are just starting out or training heavy every week, there is a weight here for you.
Solid Iron That Takes a Beating
Every bell is made from a single-piece, solid cast-iron body. No hollow sections. No welded joints. Just one dense, heavy unit that holds up through years of daily sessions.
Because the body and handle are cast as one piece, there are no seams or joints, so there are no weak points for cracks to start from.
The precision-machined flat base keeps each bell steady the moment you set it down. No rolling across the floor mid-rest. No wobble when you put it next to the rack between sets.
Wide-Bore Handle for One or Two Hands
Here is where the build really shows up in training. The ergonomic wide-bore handle fits one or two hands, which matters for goblet squats, two-handed swings, and cleans. The smooth finish gives you a clean grip, with or without chalk.
Cast iron kettlebell handles are generally wider than the handles on competition-style steel bells, and that extra room makes two-handed movements more comfortable. You stay in control through high-rep sets.
Pick Your Weight, Start Training
These cast iron kettlebell weights cover a full range that suits every level. Not sure where to begin? Women in the UK often start with 8kg; men typically pick 12kg to 16kg for their first bell.

Still unsure? Our guide to choosing the right kettlebell weight walks through which weight suits swings, presses and goblet squats.
Train Your Whole Body with One Tool
The offset centre of gravity in a kettlebell for home gym use forces your core and stabiliser muscles to work harder with every rep. That is something a standard dumbbell simply cannot match.
You can use these for kettlebell swings, Turkish get-ups, deadlifts, goblet squats, bent-over rows, and full-body circuits. One set of these covers a complete session with no extra equipment needed.
Single Bell, Matched Pair or Set?
One bell: choose a single weight. This is where most people start.
A matched pair for double work (double front squats, double clean and press, renegade rows): choose the single weight you want and set the quantity to 2. There is no separate pair option. Most people go one or two sizes lighter for doubles than they use with one bell.
A mixed-weight set: one bell of each size in the set, from the 2-4-6kg set up to the full 2kg–40kg set. A set suits moving up through the weights over time rather than training with two bells at once.
Not sure which suits you? Read one vs two kettlebells.
Keep Your Space Tidy
If you buy more than one weight, a dedicated storage solution makes training cleaner and safer. The Commercial Kettlebell Rack holds your full set off the floor, organised by size and easy to grab mid-workout. For smaller collections, the Commercial Half Kettlebell Rack is a compact option that works well in tighter home gym spaces.
Training on a hard or wooden floor? A few interlocking EVA floor mats give you a cushioned spot to set the bell down between sets.
