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 to 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 happens 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 lighter 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 cushioning between the plates.
Result: a nearly 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 feeling 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 individual dumbbells.

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

Many customers use this to create a fully fledged home gym for the first time without sacrificing a separate room. Fewer items, more peace, full functionality — this is 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 user manual.

You don't need to order anything else — unpack, 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 pick up 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 already been training with them daily for more than 5 years — and the mechanism still works just as smoothly as it did on day one. One thoughtful investment for a lifetime of training.

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

For an extra layer of protection and sound insulation, we recommend placing a workout 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, you can easily and at no extra cost. During checkout, you can choose from:

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

That 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 14 days to change your mind from the moment your order is delivered. In practice, it’s 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 will be collected on a 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; we’ll be happy to 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 on a pallet — safely, securely, and right the first time.

You will receive a message in advance with the delivery time window, 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 training advice — we’re 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 providers, we keep all individual parts in stock: locking mechanisms, individual plates, handles, and base trays.

If anything ever needs to be replaced after years of intensive use — which rarely happens — you won’t need to buy an entirely new set.

One phone call or email to our customer service and the part will be sent out immediately. That way, your investment truly remains 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 hold, feel, and try out all variants (TitanSilver™ and BlackValor™) yourself. 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 weight class best suits your goals.
