Shop Affordable Dumbbells

Build strength and tone your body with Dumbbells suited for every fitness level. Our selection of cheap dumbbells includes adjustable sets, fixed hand weights and durable cast-iron options ideal for home gyms.

Factory Buys is known across Australia for great value and quick delivery, making it easier to stay consistent with your workouts.

Choosing the right dumbbells for your workout

When shopping for cheap dumbbells, consider the style and material that best suit your routine. Adjustable dumbbells are great for saving space and switching between weights quickly, while fixed dumbbells provide stability and are often coated for comfort. Beginners may start with lighter pairs for toning and endurance, while intermediate and advanced users can progress to heavier sets for strength building.

If you’re building a home gym, pair your dumbbells with treadmills or rowing machines to support a well-rounded cardio and strength routine. A solid weight bench also allows for more controlled lifting positions and better form.

Benefits of dumbbell training

Using dumbbells provides a full-body workout that helps improve balance, coordination and muscle strength. Unlike machines, dumbbells engage stabilising muscles and allow a natural range of motion. Whether you’re performing curls, presses or squats, they can be used to target both major and minor muscle groups effectively.

Combine your lifting sessions with mobility or flexibility exercises using yoga accessories, or enhance recovery with massage guns to reduce post-workout stiffness. This mix of resistance and recovery keeps your body performing at its best.

How Does an Adjustable Dumbbell Work?

An adjustable dumbbell consists of a handle with weight plates screwed onto it. There are multiple plates with different weights so you can screw them on to the overall weight that you desire. This means that you can start with a lighter weight and gradually increase the amount of weight as you get stronger with progressive overload.


To adjust the weight, simply unscrew the handle from the weight plate and add or remove plates as needed. Then screw the cap on to keep the weights tightly in place and you're ready to go.

Is it Worth it to Get Adjustable Dumbbells?

For some people, adjustable dumbbells may be a wise investment. They offer a number of benefits, including convenience and affordability. If you are serious about lifting weights and getting in shape, then having dumbbells at home allows you to do extra sets at home. Or, if it's inconvenient for you to go to the gym, you can use your dumbbells at home to do a mini workout so you won't feel guilty for not going.


Adjustable dumbells are also good for beginners because you can start with a lower weight and gradually increase the amount you lift as you get stronger. Additionally, if you have limited space at home, adjustable dumbbells take up less room than multiple sets of dumbbells.


There are a few things to consider before buying adjustable dumbbells. First, adjustable dumbbells can be cheaper than buying a rack of traditional dumbbells. Second, you should make sure you buy from a reputable brand so that you know the weights will be accurate and robust. Finally, check the reviews online to see what others think about the dumbbells you're considering.


Overall, adjustable dumbells offer a number of conveniences and benefits that may make them worth the investment for most people. However, if you buy cheap dumbbells made of plastic (not sold at Factory Buys) then be mindful of how you put them down or they might break.

What Are the Benefits of an Adjustable Dumbbell Set?

  1. You can adjust the weight of the dumbbell for each exercise.

  2. An adjustable dumbbell set takes up less space than a traditional dumbbell set.

  3. An adjustable dumbbell set gives you more exercise options because of the variety of weight settings.

  4. With more weight options, you can do progressive overload on your muscles over time leading to greater strength gains.

  5. An adjustable dumbbell set is more cost-effective than a traditional dumbbell set because you buy one bar with multiple weights instead of multiple bars with weights.

  6. Some muscle groups recover faster than others. If you have a set of dumbbells at home it will allow you to work these muscles more frequently.

How Heavy Should Adjustable Dumbbells Be?

The weight of adjustable dumbbells varies depending on the model and brand. However, the adjustable dumbbells at Factory Buys range from 12 to 40 kg per set. How heavy your dumbbells should be will depend on your strength and what exercises you want to use them for.


If you're doing an exercise that isolates a specific muscle group that is small, like your delts, then you won't need as much weight to strain the muscle. However, if you're going to do compound exercises that work more than one muscle at a time and bigger muscle groups, such as the squat, then you will need more weight in order to push yourself. Likewise, if you're an experienced weightlifter you will want the option to have more weight, even for isolated exercises.

What Dumbbell Sizes Are Available?

All adjustable dumbbell sets from Factory Buys come with at least 1 handle and attachable weights. Most sets come with 2 handles but there is a 1-handle 40kg set for serious lifters. The dimensions (width x height x length) range from 27cm x 9.5cm x 45cm for a 12kg set to 26cm x 36cm x 53cm for a 40kg set. The size of each dumbbell can be viewed in the dimensions tab of each product.

What Size Dumbbells Should I Start With?

If you are a beginner, we recommend starting with the 10kg, 15kg or 20kg set (depending on your budget). This will allow you to start light and work your way up. The lighter sets are also cheaper than the heavier ones. As you get stronger, you can add more weight until the max weight becomes easy for you. Then you can consider getting a heavier set.


For those who are already lifting weights or have some previous experience, we recommend getting either the 30kg or 40kg set depending on your strength and goals. These weights give you more exercise options and you can set it to how light or heavy you need for each exercise.


If you've had an injury and would like to use dumbbells for rehabilitation, or just to keep your muscles healthy as you age, we recommend getting a set of 3kg, 5kg and 8kg dumbbells - you can get an adjustable set that includes all sizes the Adjustable Dumbbells 2.5kg-24kg (Pairs).
