Dumbbells: the Sidea selection
Dumbbells are one of the most versatile pieces of equipment in weight training. They allow for a free range of motion, require active stabilisation, permit asymmetrical loads and are suitable for training programmes ranging from maximum strength to hypertrophy, and from rehabilitation to fitness conditioning. The Sidea range comprises over 20 products: fixed dumbbells in PU, hexagonal rubber, chrome-plated and vinyl; adjustable dumbbells with a disc mechanism; loadable dumbbells; and complete sets ranging from 76 kg to 360 kg. A range designed both for the complete fitting out of a dumbbell room both for professional use and for compact solutions from home gym.
Who are Dumbbells for?
Strength and conditioning coaches working with strength athletes will find that the 360 kg Round Pro PU kits — featuring dumbbells weighing up to 50 kg per pair — provide the full range needed for exercises such as heavy dumbbell presses, rows, curls and split squats. Those who run a CrossFit box or a functional training studio tend to prefer hexagonal rubber for its impact resistance and ease of daily maintenance.
Personal trainers working in a studio often have limited space: here, the NÜOBELL adjustable dumbbells (2–32 kg) provide a clear-cut solution, replacing up to 16 pairs of fixed dumbbells with a single quick-select piece of equipment. For group classes, aerobics or Pilates Reformer sessions, the choice is between chrome or vinyl dumbbells, which are lightweight, have comfortable grips and range from 1 to 10 kg.
Home gym enthusiasts looking for professional-grade equipment — not consumer-grade — will find it in the training kit Sidea: a straightforward answer – 76 or 110 kg sets in vinyl, chrome or hexagonal PU, with a rack included in some configurations. No compromises on materials compared to what you’d find in a gym.
How to choose
The first criterion is the surface material. Solid rubber (hex rubber) is the standard choice for professional weight rooms: it withstands accidental drops, does not roll away, protects the floor and has a lifespan spanning decades, provided it is not subjected to excessive heat or direct UV exposure. Polyurethane (PU) offers a more compact surface with a smooth finish and is preferred when the gym’s aesthetics are important — boutique gyms, photography studios, hotel fitness centres. Chrome is suitable for light weights up to 30 kg, offering a precise grip and a clean look. Vinyl is the entry-level choice for rehabilitation settings or aerobics classes.
The second criterion is the format. Fixed dumbbells offer immediate accessibility — which is essential in a gym where several users take turns using the same equipment. Adjustable dumbbells, such as the NÜOBELL, optimise space and total cost, but require a second to select the weight: acceptable for structured individual workouts, but less practical in high-turnover environments. Dumbbells that can be loaded with 28 mm discs strike a balance: they allow for fine-tuned load progression but require an extra minute of set-up.
The third criterion is the weight range. For maximum strength training, you’ll need dumbbells weighing up to 40–50 kg per pair. For conditioning and functional circuits, the 8–30 kg range covers most training programmes. For active mobility or rehabilitation work, weights of up to 10 kg are sufficient. Choosing the right size kit ensures you don’t buy too much — or too little — in relation to your actual usage patterns.
Sidea Products for Dumbbells
The range is divided into four main families.
Fixed dumbbells made from PU and hexagonal rubber. The Round Pro PU Dumbbell (8802V–8879V) features a round polyurethane body with a cast steel core, available as a pair or in a kit of 26 pairs totalling 360 kg. The Hex Rubber Dumbbell (8904K26) replicates the 360 kg kit configuration in hexagonal rubber, with anti-roll heads. The Fit PU Dumbbell (1181–1190) completes the PU range with a more affordable line for mid-level studios and gyms.
Chrome, vinyl and neoprene dumbbells. The chrome dumbbells (1161V–1170V) cover the light weight range and feature a knurled grip. The 76 and 110 kg vinyl sets, complete with matching rack, are designed for training studios and rehabilitation centres. The neoprene dumbbells (2121V–2132V) provide a soft grip for therapeutic settings.
NÜOBELL adjustable dumbbells. The NÜOBELL 232 system offers weights ranging from 2 to 32 kg per dumbbell, with disc selection in 1 second. Available as a single pair, in a kit with a dedicated rack, or as a separate rack for those who already own dumbbells. A solution designed specifically for the functional training in compact spaces.
Adjustable dumbbells and compact sets. The 8800/4 and 8800/6 adjustable dumbbells accommodate 28 mm discs and can be set to a maximum of 11.5 and 13.5 kg respectively. Ideal as travel kits or for personal training studios with limited budgets and space, where fine load progression takes priority over the speed of weight changes.
Rounding off the range, the Seal Row Bench (9021) and the Flex Bench (9017) are the ideal platforms for unilateral exercises with heavy dumbbells, from the chest-supported row to the inclined dumbbell press.
Why choose Sidea
Sidea has been operating in the professional fitness equipment sector since 1999, with a warehouse covering over 4,000 m² and a technical team capable of supporting both individual purchases and the complete fit-out of weight rooms, including a Gym Design service and 3D renderings. Our selection of dumbbells is not simply put together to fill a catalogue: each item has been assessed for the durability of the materials, the construction standards of the steel handles, tolerance against the stated weight, and compatibility with available dumbbell racks. For those setting up a weights room from scratch or replacing worn-out stock, direct technical advice enables you to correctly size kits and dumbbell racks before purchase.

Polyurethane (PU) has a more compact and smooth finish, greater resistance to surface abrasion and a more polished appearance: it is the preferred choice in boutique gyms and studios where aesthetics matter. Hexagonal rubber (hex rubber) is more economical, absorbs accidental drops better thanks to the greater mass of the coating, and the six-sided shape prevents the dumbbell from rolling away. In a heavily used weight room, hex rubber is the standard choice for durability and low maintenance.
-
NÜOBELLs are ideal for individual use: personal trainers in studios, home gyms and single-user spaces. In a gym with open access and high turnover, the quick-select mechanism may suffer accelerated wear and tear if used incorrectly by untrained users. For high-intensity multi-user environments, fixed dumbbells remain the most robust solution. NÜOBELLs are best suited to gyms when allocated to a specific, supervised area.
-
It depends on the type of gym and the expected user base. A general-purpose weight room with 10–15 simultaneous stations typically requires at least two complete sets ranging from 5 to 40 kg (in increments of 2.5 or 5 kg), i.e. 15–20 pairs. A CrossFit box or functional training studio often caps at 30 kg and invests in multiple pairs per weight. The 360 kg Sidea kits, comprising 26 pairs, are designed to cover the entire room with a single product range.
-
The Sidea loadable dumbbells (8800 series) are designed for standard weight plates with a 28 mm bore diameter, the same standard as short Olympic barbells and pump bars. Before using third-party discs, it is advisable to check the bore diameter and thickness: discs that are too thin may compromise the stability of the locking collar. Sidea can provide details of tested and compatible combinations on request.
-
The Seal Row Bench (9021) is designed for supported rowing exercises with heavy dumbbells, typically over 20 kg for advanced athletes: it is compatible with Round Pro PU or Hex Rubber weights in sizes 20–50 kg. The Flex Bench (9017), a multi-angle adjustable bench, is suitable for presses, curls, flys and split squats: it works well with the entire range, from lightweight chrome dumbbells to PU dumbbells up to 40 kg. The choice of dumbbell depends on the exercise and the user’s level, not on the bench.
-
Rubber and PU degrade mainly due to prolonged exposure to direct UV rays, aggressive solvents and extreme temperatures. In standard indoor environments (15–28°C, no direct sunlight), the lifespan is 8–15 years with routine maintenance. For cleaning, simply use water and mild soap or products specifically designed for technical rubber. Avoid concentrated alcohol-based sprays, bleach and abrasive products. The handlebar rack reduces the risk of deformation caused by the handlebars resting incorrectly on the floor.
