Dumbbells

Browse our full range of dumbbells for strength training, from competition-grade hex dumbbells / rubber-coated models to space-saving adjustable dumbbells and complete dumbbell sets with racks. Dumbbells in this collection are made for daily use in commercial gyms and home gyms, with knurled steel handles, tight weight tolerances, and finishes that hold up under heavy use. Whether you're putting together a compact home gym or setting up a commercial facility, you can create a dumbbell setup here that fits your space, demand, and training environment.

How to Choose the Right Dumbbells

Picking the right set of dumbbells comes down to basically three major questions: what weight range you need, whether you want fixed or adjustable, and which build matches your training style, frequency and overall needs. Here's a quick guide to help you decide before you scroll.

Fixed Dumbbells vs. Adjustable Dumbbells vs. Dumbbell Sets

Fixed dumbbells come in a single, permanent weight. They're ideal if you train heavy, need immediate pick-up-and-go use, and have the floor space or a rack to store a full set. Fixed dumbbells are the standard in every commercial gym because they survive drops & last.

Adjustable dumbbells let you change weight by swapping plates or turning a dial. They're the most space-efficient option and the go-to for home gyms where floor space is limited. Modern adjustable systems cover a broad range suiting lifters.

Dumbbell sets are typically sold in increments like 2.5 kg to 25 kg or 5 kg to 50 kg, often with a rack. They're the fastest way to build out a home gym or studio. Buying as a set usually works out cheaper than piecing individual pairs together.

What Weight Dumbbells Should I Buy?

Choose the weight according to your specific use case. Dumbbells are an extremely versatile piece of equipment, so covering a broad range of weights opens up endless options for workouts across nearly every sport or training style.

The right load depends on the exercise, your training goal, and where you currently are as a lifter. A 6 kg dumbbell can be light work for one person and a serious challenge for another, on the exact same exercise. Treat the ranges below as a rough orientation, not a strict rulebook.

Light dumbbells in the lower single digits up to around 10 to 15 kg are used across all training levels. Even strong lifters reach for them daily for rehab and prehab work, rotator cuff sets, lateral raises, rear delt flys, and high-rep isolation sets where strict form matters more than the load. Don't write them off as "small weights".

Mid-range dumbbells, roughly to 40 kg, cover the bulk of hypertrophy work for most lifters: bicep curls, tricep extensions, bent-over rows, goblet squats, lunges, Turkish get-ups, and moderate farmer's carries. Where exactly you land in this band depends entirely on the exercise and your strength on it. This is also the range most home gym lifters reach for on a daily basis.

Heavy dumbbells starting from around 35-40 kg upward, come into play for compound lifts such as dumbbell bench press, incline press, one-arm rows, Bulgarian split squats, Romanian deadlifts, and loaded step-ups. For experienced lifters, 30 to 50 kg is the working range for these movements.

Above 50 kg, you're in heavy lifting territory: dumbbell push press, loading events, heavy farmer's walks. These are the peak loads commercial gyms need to stock for their strongest members.

Like Thor's hammer, some dumbbells are genuinely hard to pick up. Our heaviest fixed hex dumbbell weighs in at a whopping 100 kg. For our strongmen and strongwomen, we have another treat: the loadable monster dumbbell, with an empty weight of 38 kg. Old-school circus dumbbells, straight out of the early days of lifting, are also part of the collection.

As an alternative to fixed dumbbells or adjustable dial mechanisms, we also offer plate-loaded dumbbells. They take standard plates of any weight with a 50 mm Olympic opening.

For a well-equipped home gym, a set from 5 kg up to 32.5 kg is a solid starting point and covers the majority of pressing, rowing, and accessory work. For commercial facilities, strongman training, or advanced strength athletes, extending the rack to 50 kg dumbbells or beyond becomes the expected minimum standard.

Dumbbell Materials and Shape: Rubber, Hex, and Cast Iron

Not every dumbbell is built the same. The materials and construction define how your dumbbells hold up over the years, and how smoothly they integrate into your day-to-day training 

Rubber dumbbells use a cast-iron core coated in dense rubber or urethane. They protect your flooring, reduce noise on drops, and don't chip or rust. The standard choice for home gyms and any studio with wooden or rubber flooring.

Hex dumbbells get their name from the six-sided head, which stops them rolling when you set them down mid-set. The hex shape is also the most stable for dumbbell push-ups and renegade rows. A commercial-gym staple for good reason.

Cast iron dumbbells are the original. Bare iron or chrome-plated, with no rubber jacket. They feel compact in the hand, take up less rack space per kilo, and have a classic look that fits purist strength setups. Best suited to platforms or floors that can take the impact.

Commercial-grade construction across our range means hardened welds or one-piece cast heads, and tight weight tolerances. Plus, full knurling on the handle for grip under sweat. Only exceptions; our circus dumbbells & monster loadable dumbbell, rely completely on your raw grip strength. Good moment to also browse our grip strength collection.

Dumbbells for Home Gym and Commercial Setups

A pair of dumbbells is a strong starting point for almost any setup. With the right supporting equipment, they become part of a well-rounded and highly usable training floor. 

For a home gym, most lifters start with a pair or a compact dumbbell set and pair them with an adjustable weight bench for pressing, rows, and step-ups. If you're going the fixed-weight route and want to keep things tidy, a dedicated dumbbell rack is worth the investment from day one. A dumbbell pair from 5 kg to 32.5 kg plus a rack covers a good range, to start off from.

For a commercial gym or studio, the priority shifts to durability, throughput, and completeness. A full rack of hex / rubber dumbbells from 1 kg to 50 kg is the baseline. Members expect every weight jump available, and the build needs to handle daily drops without maintenance. With free weights, a proper flooring is a non-negotiable. Layout our Granuflex rubber flooring tiles to protect your new dumbbells and the floor of your facility. Commercial setups typically pair dumbbells with heavy-duty flat and incline benches, and enough rack space that nothing gets stored on the floor.

FAQ: Dumbbells

What size dumbbells should I buy?

It depends on your current strength and main goal. For most beginners, a pair of 5 kg to10 kg dumbbells covers the first few months. Lifters doing hypertrophy work typically need more. Advanced lifters pressing heavy should at least plan for 30 kg and up. If you can, go to a gym and see what your current level is for the planned exercises.

Are adjustable dumbbells as good as fixed?

For most home gym training, yes. Modern adjustable dumbbells cover a large weight range most lifters use and save a lot of space. The trade-off: they're a bit slower to change between sets and they don't handle drops the way fixed hex or rubber dumbbells, in general do. For commercial use, high-rep circuits, or heavy dropping, fixed dumbbells remain the standard.

What's the difference between hex and round dumbbells?

Hex dumbbells have a six-sided head that stops them from rolling and provides a stable base for push-ups and renegade rows. Round (or "pro-style") dumbbells have a circular head that's easier on the rack and can feel more balanced in heavy pressing. Hex is more common in commercial gyms, round is the classic competition and strength-sport shape.

Rubber or cast iron dumbbells: which is better?

There is no universal “better” option between rubber and cast iron dumbbells. Rubber-coated models are typically used where durability and noise reduction matter, such as in commercial gyms. Cast iron dumbbells are simpler and take up less space, which suits many home gym setups. Each has its place depending on the setup and usage. 

Do I need a rack for my dumbbells?

For a pair or two, no. A corner of the floor works fine. Once you own three or more pairs, a rack is really worth it. It keeps the weights off your flooring and extends the lifespan of both the dumbbells and the floor beneath them.
