L'entraînement en force

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.

Base the range on the exercises you plan to do. Lateral raises and other isolation work need light dumbbells, while rows, presses and Romanian deadlifts need noticeably heavier pairs, so a home setup usually covers a spread of weights rather than one pair. Choose loads you can control for the full set and leave room to progress. BLK BOX Rubber Hex Dumbbells run from 2.5kg to 60kg in 2.5kg steps, 12 Sided Urethane Dumbbells from 1kg to 60kg, and dumbbell sets are available in ranges such as 2.5kg to 30kg, 40kg or 50kg. Where space is limited, PowerBlock Pro EXP adjustable dumbbells replace a full rack, expanding from 5lb to 100lb per hand.

Choose the tool that matches the movements you train most. Dumbbells give broad exercise variety with simple setup, kettlebells suit swings, carries and technical ballistic work, while a barbell setup gives the clearest route to heavier progressive loading. Many strength spaces use all three over time rather than treating them as direct substitutes.

A complete strength setup normally combines a primary resistance system with supporting free weights. For barbell-based training that means a rack, bench, Olympic bar and plates; dumbbells and kettlebells add unilateral and accessory work, while cable or plate-loaded machines can fill specific movement gaps.

For a small studio, prioritise equipment that serves several clients and movement patterns from a compact footprint: a rack or NEXUS system, adjustable bench, dumbbells or kettlebells, Olympic bar and plates, plus modular storage. Add specialist machines only where the coaching programme needs them.

Map the programme by movement: squat, hinge, horizontal press and pull, vertical press and pull, carry and accessory work. Then select equipment that covers those movements without unnecessary duplication, using attachments or cable systems to fill gaps before adding another large standalone station.

A rack, barbell and adjustable bench cover major upper- and lower-body strength movements, while dumbbells, kettlebells and cable attachments extend unilateral and accessory work. If one footprint needs to cover both, a NEXUS rack combines barbell, pull-up and cable training.

If a full rack will not fit, consider a squat stand, folding rack, compact rack or a rack-and-cable system with a shallow footprint. The best option is the smallest setup that still gives safe bar support, the required exercise range and enough surrounding working space.

Barbells and plate-loaded systems offer a straightforward route to heavier loading by adding Olympic plates, while selectorised cable stacks and heavier dumbbell or kettlebell pairs add progression in fixed increments. Choose the progression method that matches the exercises and users you expect over the next few years.

Alongside a barbell and plates, plan for a stable rack or squat stand, compatible J-Hooks, appropriate safeties and collars. Add a bench for pressing and storage for plates and bars so the working area remains clear.

With a limited budget, cover the largest number of movements first: rack or stands, bar and plates, then a bench. Add free weights, storage and cable or machine options once the core strength movements are covered and you know where the programme still has gaps.

For simultaneous client training, duplicate the stations that create waiting time. A group programme where everyone squats together needs more rack stations; a circuit can use fewer duplicate stations because clients rotate. Plan equipment quantity from session format rather than total membership.

Include storage for the free weights you are actually buying: barbell holders, plate pegs or trees, dumbbell shelving and kettlebell shelves. Modular Basecamp storage can combine several equipment types and expand as the studio grows.

Use the suitability information on the exact product rather than assuming every item has the same commercial rating. 3 Series is aimed at commercial gyms, PT studios and group-training environments, 5 Series at elite high-performance facilities, and selected 1 Series products are suitable for PT studios and compact commercial spaces. General BLK BOX warranty terms still apply subject to product-specific conditions.

We offer Rubber Hex Dumbbells, Urethane Dumbbells, and Adjustable Dumbbells, each designed for performance, durability, and grip security.

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.

We offer a range of benches, including the Utility Flat Bench, Utility Adjustable Bench, Soft Bench Adjustable Bench and 5 Series Adjustable Weight Bench.
