In less than 3 seconds. Simply turn the handle to the desired weight, hear the confirming click — and you're ready for your next set.

No changing plates, no loose weights, no interruption of your flow. One smooth movement between 4 and 41.5 kg per dumbbell.

This lets you train faster, more intensely, and with complete focus on what matters: your progress.

For anyone who is serious about their training — at any level.

The LION® Adjustable Dumbbells come in three variants: up to 23.5 kg, up to 32.5 kg and up to 41.5 kg per dumbbell.

Adjustment is done in fine 1.5 kg increments, so you can choose exactly the right weight for every set — crucial for progressive overload and controlled recovery. Whether you're starting with light exercises or have been lifting seriously for years: there is always an edition that grows with you.

One set, one investment, for every training goal and every phase of your journey.

Both editions deliver exactly the same performance, quality, and lifespan — the difference lies in the training experience.

The BlackValor™ features a premium black coating and nylon damping between the plates.
Result: an almost silent, stylish set that fits perfectly in a modern home gym.

The TitanSilver™ has a steel-on-steel finish and a classic, industrial character. It delivers that unmistakable, powerful sound and feel of real ironwork with every rep. Which one you choose is purely a matter of taste — both are built to last for generations.

One LION® set replaces up to 52 separate dumbbells.

That means: no more heavy dumbbell racks, no cluttered training corner, no wasted square meters in your home.
Everything you need fits in the space of one small table.

Many customers create a fully functional home gym for the first time without sacrificing a separate room. Less equipment, more peace, full functionality — that’s what a premium home setup should look like.

You receive a fully ready-to-use set: two LION® Adjustable Dumbbells in the variant you selected, both sturdy base trays in which you place the dumbbells between sets, and a clear instruction manual.

You don’t need to order anything else — unbox, place, and train.

Everything we include is developed for daily use and contributes to the premium look in your home gym.

Yes, completely.

The LION® Adjustable Dumbbells™ are designed for daily, heavy use — both at home and in professional settings.

The triple safety mechanism automatically locks each plate as soon as you lift the handle, so nothing can ever come loose during your set. Stable in every rep, even during heavy compound lifts such as chest press, rows, and lunges.

Thousands of customers train with them daily without a single incident — safety is not a feature, it is the standard.

Yes, absolutely. The LION® Adjustable Dumbbells™ are built to last a lifetime. Premium materials, an industrial locking system, and strict quality control ensure that every set stands the test of generations.

Many customers have been training with them daily for more than 5 years — the mechanism still works just as smoothly for them as it did on day one. One conscious investment for a whole lifetime of training.

Yes. The base trays the dumbbells rest on distribute the weight evenly, allowing them to be placed directly on most floors — think laminate, vinyl, tile, or concrete.

For an extra protective layer and sound dampening, we recommend placing a training mat underneath, especially on hard floors or upper levels. Many customers choose a rubber fitness mat — a small investment that protects your floor perfectly.

Yes, easily and at no extra cost. During checkout you can choose from:

• Klarna — Pay Later: receive your set now, pay afterwards within 14 days.
• iDeal in 3 installments: spread your purchase safely and interest-free over three monthly installments.

This way, you don’t have to wait for something you truly deserve. You train today, and spread the investment over a few months.

You legally have a 14-day cooling-off period from the moment your order arrives. In practice, it is rare for a set to be returned — the quality is convincing almost immediately. If you still decide to return it, the return costs are at your own expense (the set is collected by pallet).

Still unsure? Feel free to visit our showroom in Sliedrecht. There you can hold, feel, and test the dumbbells yourself — so you can buy with 100% confidence. Make an appointment by phone or email, and we’ll gladly take the time for you.

If you order on a business day before 5:00 PM, your set will generally be delivered the next business day.

Because these are heavy premium products, we deliver by pallet — safely, protected, and done right in one go.

You will receive a message in advance with the time slot, so you know exactly when you can start your first workout.

Your order is prepared with care, securely packaged, and delivered to your home on a pallet — safe and fully ready to use.

As a Dutch brand, we stay close to our customers: questions are answered quickly, personally, and in Dutch. In addition, you receive a standard 3-year manufacturer's warranty on every set.

If anything ever comes up — a part, a maintenance question, or simply advice about your training — we are here for you. Think of it as the peace of mind that comes with a premium purchase: you train, we take care of the rest.

Yes — and for adjustable dumbbells, that is virtually unique in the Netherlands. As one of the few suppliers, we keep all individual parts in stock: locking mechanisms, individual plates, handles, and base trays.

If after years of intensive use something ever needs to be replaced — which rarely happens — you won’t need to buy your entire set again.

One phone call or email to our customer service and the part will be sent immediately. This keeps your investment truly usable for a lifetime. That is the difference between a product that is sold and a product that is truly believed in.

Yes, and we highly recommend it.

You are welcome in our showroom in Sliedrecht, where you can personally hold, feel, and try all variants (TitanSilver™ and BlackValor™). Here you will immediately notice the difference compared to cheaper alternatives — the weight, the finish, the clicking sound of the lock.

Our specialist will take plenty of time to advise you on which variant and which weight class best suits your goals.
