Dumbbells

Our Range of Dumbbells

Factory Weights stocks reliable, high-quality gym weights that are built to last for years. Our extensive product knowledge and low overheads mean we can help you build strength at a low cost. 

Here’s what you can expect from our premium dumbbell collection. 

Fixed Dumbbells

Our selection of round and hex dumbbells features knurled steel handles for a secure grip during lifts and bicep curls. Coated with rubber, urethane or neoprene, these fixed dumbbells offer increased durability and longevity. 

We also stock dumbbells with different shapes on either end, including more traditional rounded ends and hexagonal designs that prevent rolling.

Adjustable Dumbbells

Explore adjustable dumbbells made up of multiple removable plates, letting you change your load with ease and precision. A main benefit of adjustable dumbbells is their versatility. Use their compact size as individual hand weights or add a centre barbell attachment to transform them into a full bar.

An adjustable dumbbell set is perfect for any beginner looking to gradually increase their load. Choose from a range of loading variations, which include: 

• 20 kg weights 

• 30 kg weights

• 50 kg weights

We also stock commercial-grade 32 kg quick-set adjustable dumbbells, a perfect mid-range option to shatter lifting plateaus when jumping from 30 kg to 50 kg.

Loadable Dumbbells

If your home gym has limited space, loadable dumbbells help keep your floor clear. These space-saving handles work just like a mini barbell. 

Simply:

1. Slide your existing Olympic plates onto the sleeves.

2. Clamp on the spring collars.

3. Get to work.

By adjusting the plate stack to match your target lift, you avoid the need for a massive, expensive racking system during a heavy session.

Competition Dumbbells

Our Strongman dumbbells are engineered for:

1. Pure overhead power

2. Brutal press work

3. Serious grip training. 

The Strongman Circus Dumbbell replicates the classic weights hoisted by old-school lifters, featuring a massive 60 mm-diameter handle that maximises core and upper-body recruitment. Built from solid steel for elite durability, these individually sold, heavy-duty competition dumbbells range up to 110kg to challenge your overhead lockout power.

Dumbbell Pairs

Our commercial urethane dumbbells and neoprene-coated hex dumbbells are available in pairs and range from 1 kg to 60 kg. Depending on your fitness goals, you can use lighter dumbbells for aerobic exercises or heavier ones to boost your muscle-building. 

Dumbbell Sets

Dumbbell sets are ideal for both commercial and home gyms due to their wide range of weights, allowing you to progressively increase your load. 

• Our hex dumbbells are available in 1 kg – 10 kg and 5 kg – 30 kg sets. 

• We also stock smaller neoprene dumbbells that only go up to 2.5 kg.

With such a versatile assortment of hand weight sets available, you can find the ideal dumbbells that match your current or desired fitness level.

Dumbbell FAQs

Find answers to frequently asked questions about our dumbbells for sale.

How do I choose between fixed & adjustable dumbbells?

Choosing between fixed and adjustable dumbbells comes down to your:

1. Budget

2. Training style 

3. Available floor space

Both styles are highly effective for strength training, but they function differently depending on how you structure your workouts. To find the most suitable setup for your home or commercial gym, consider these key factors:

• Adjustable dumbbells stack an entire weight rack into one compact, space-saving pair, letting you quickly change plates to match your progressive fitness training.

• Fixed dumbbells provide a highly comfortable, traditional gym feel with zero setup, making them perfect for rapid circuit workouts and intense strength training.

Ultimately, the main difference is speed versus space. If your routines require you to constantly change weights on the fly, a set of fixed bells on a rack is faster. If you want to save space, go adjustable. 

Pro tip: Before buying, check the details of your training program to choose a system that works seamlessly with your lifting style.

Which is better, steel or cast iron dumbbells?

Steel offers a polished, professional look and higher natural resistance to rust and corrosion. In contrast, traditional cast iron weights deliver a dense, classic lifting feel that can last a lifetime if handled with care.

Explore the main differences in steel and cast iron construction to see how these materials stack up on the gym floor:

Dumbbells are usually made of cast iron or steel and are often coated in rubber to prevent serious injury or damage when dropped. Adding a rubber, urethane or neoprene exterior coating makes a massive impact on performance. 

This outer layer:

1. Reduces iron-on-iron noise.

2. Helps protect your gym floor from chipping.

3. Ensures your steel or cast-iron weights don't sustain surface damage from heavy drops.

Pro tip: Regardless of the metal core you select, ensure you pick handles with high-quality knurling. A secure, textured grip is vital for maintaining complete control and staying safe during maximum-effort overhead lifts.

What are the best dumbbell exercises for building muscle? 

Heavy compound lifts are one of the best dumbbell exercises for building muscle, torching multiple muscle groups at once. Integrating these versatile free weights into your weekly workouts is a great, convenient way to train your entire body right from home.

Prioritise these core lifts for optimal strength training results:

• Squats and lunges: Heavy lower-body staples that tone the quads, glutes and core.

• Floor press: A premier upper-body push designed to build strength in your chest.

• One-arm rows: Essential movements for direct back strengthening and grip power.

Tip for beginners: Perform these movements with a comfortable grip to protect your joints from strain. When you’re ready to build more muscle, apply progressive overload by gradually increasing the dumbbell weight.

What other types of free weights do you stock?

While a heavy-weight dumbbell setup is great for isolation movements, branching out keeps your workouts fresh. Expanding your kit makes it easier to train your entire body and find new ways to build power.
