Kettlebells

Choose by movement rather than a single number. Swings and deadlifts are driven by the hips, so most people can use a heavier kettlebell for them than for presses, snatches or Turkish get-ups, which rely more on the shoulders and technique. Pick a weight you can control for every rep of your planned sets, then progress. BLK BOX cast iron kettlebells run from 4kg to 40kg, and the Premium Cast Iron and dual-marked Competition Kettlebells add 2kg steps between 4kg and 16kg, so lighter progressions do not have to jump a full 4kg at a time. Competition Kettlebells keep the same size at every weight, which keeps technique consistent as the load increases.

Buy one kettlebell when the programme mainly uses unilateral or alternating work, a matched pair when you regularly train double-kettlebell lifts or carries, and a set when several weights are needed for progression or shared use. The best format follows the exercises and number of simultaneous users, not a fixed rule.

Cast iron kettlebells are solid iron and increase in physical size as weight rises. Competition kettlebells are steel with the same body dimensions across the range and a 33mm handle, while urethane kettlebells also use a standardised body and handle profile with a protective urethane coating.

For general home strength training, cast iron kettlebells are the simplest value-focused option and their size increases with weight. Choose competition kettlebells when consistent dimensions and technical lifts matter, or urethane kettlebells when you want a consistent shape with a durable premium finish for home or commercial use.

Match the shelf to both the kettlebell style and quantity. A 1.2m Basecamp flat shelf can hold up to about five cast-iron or four competition kettlebells, while a 1.8m shelf can hold up to about eight cast-iron or seven competition kettlebells.

Competition Kettlebells use a 33mm handle diameter and list 120mm between the handles. Other kettlebell families use different geometry, so use the product-specific dimensions if handle clearance is important for two-handed work or storage.

Competition kettlebells use the same 280mm body height and standard dimensions across all available weights. Urethane kettlebells are also standardised across the range, while cast iron kettlebells increase in body size as the weight gets heavier.

Cast iron kettlebells use an e-coat or textured powder-coat finish and change size with weight. Competition kettlebells use steel with a naturally brushed, rust- and scratch-resistant handle coating, while urethane kettlebells add a protective urethane body coating and chrome steel handles for a cleaner commercial finish.

Yes. Order two of the same weight and kettlebell family when paired movements are part of the programme. Competition and urethane kettlebells are particularly useful for matched pairs because their dimensions remain consistent across the range.

Use the largest kettlebell dimensions when checking storage, not the lightest. Competition kettlebells are 280mm high and have uniform dimensions, while cast iron bells grow with weight, so storage fit can change as the collection becomes heavier.

In a group-training studio, keep kettlebells dry and organised, inspect handles and coatings for damage and provide enough weight options to reduce unnecessary sharing between active stations. Urethane and competition ranges give consistent handling for repeated technical work, while storage keeps the floor clear between sessions.

Set contents are product-specific. Check the selected kettlebell set or bundle for an itemised list of included weights before ordering, particularly if you need a continuous progression rather than a broad mixed set.

Heavier or multi-kettlebell orders may be split across parcels or sent on a pallet depending on the total shipment. Delivery charges and method are calculated from the order, so plan the receiving point for the complete weight rather than one kettlebell at a time.

The main differences between a kettlebell and a dumbbell are related to their shape, grip, and the type of exercises they are best suited for.

In short, if you're looking for a tool that allows for dynamic, full-body movements and builds both strength and endurance, a kettlebell is a great choice. If you prefer more controlled, targeted strength training for individual muscles, dumbbells are ideal.
