What Are Adjustable Dumbbells?

Adjustable dumbbells are a set that can be set to a variety of different weights. When you’re at the gym, there’s usually a rack of dumbbells ranging from a few kilograms up to about 40-50 kg.

If you have a home gym, your options are to buy a whole rack, buy a single dumbbell and stick to that weight indefinitely, or buy a set that you can adjust.

Buying dozens of different dumbbells isn’t cost-effective or practical for most people. Buying one non-adjustable set isn’t a great option either. For example, if you bought a 20 kg set of dumbbells, your only way of progressing your workouts is by increasing the volume of your lifts. However, unless you want to end up doing hundreds of reps per session, there’s an easier way.

This is where adjustable dumbbells come in. With that one set, you can work through a range of weights with ease without disrupting your sets very much.

What Are the Different Types of Adjustable Dumbbells?

There are two types of adjustable dumbbells — those with spinlocks that you can manually adjust and dial-a-weight style ones.

Spinlock dumbbells are like tiny barbells. Each one comes with weight plates that you can manually load and lock with a spinning clip. They’re generally much cheaper than the dial adjustable dumbbell. However, they usually don’t let you go as heavy, and they’re slower to load. 

The dial dumbbell style offer several advantages. Most importantly, you can quickly change the weight on them. If you plan on using the dumbbells for circuits or for a workout where you need to alternate between weights often, you’ll be better off with this style so you don’t spend half your workout changing plates – simple twist a dial to select the desired weight and you are ready to go.

However, the dial-a-weight sets are generally about three times more expensive than the spinlock types. They usually max out around 20-25 kg depending on the brand.

Benefits of Adjustable Dumbbells

Buying a pair of adjustable dumbbells is a great investment in your home gym. Even though some sets, especially the dial-a-weight variety, can be a big upfront expense, over time they can save you money by reducing the number of dumbbells you need to buy. If you take care of them, they should last for a long time.

If you live in an apartment or have a limited amount of room for building your home gym, you’re probably concerned with being space-efficient. Adjustable dumbbells are a huge space saver. Instead of having to dedicate an entire wall to a huge rack of various sizes, you can just have one pair of dumbbells instead.

If you ever decide to move to a new home, the move will be much easier too without having to worry about moving a whole wall of weights.

Do you consistently include dumbbell work into your weekly routine? Lifting with dumbbells offers several advantages over lifting with barbells. Since each of your hands move individually, your small stabiliser muscles have to work harder to control the plane of motion. These may help you correct muscle imbalances since each limb has to do the same amount of work.

If you look at the bodies of athletes in sports like tennis where one arm is used significantly more than the other, it’s not uncommon to see that the athletes have a huge disparity in muscle mass between their dominant and non-dominant sides.

No matter whether you’re a competitive bodybuilder or just lifting to look good, you can include dumbbell work into your routine to prevent building these types of muscular imbalances.

Considerations Before Buying Adjustable Dumbbells

Before you buy a pair, it would be a good idea to ask yourself how heavy you plan on lifting. Most go up to about 20-25 kg so anything above this and they might not fit your purpose.

If you spend most of your time under 20-25 kg but you like to do a few heavier sets in your routine, you can add a few extra kilograms to your lifts by wearing wrist weights. If you often lift over 30 kg, you may want to invest in one or two sets of regular dumbbells and save the adjustable ones for your accessory exercises.

They come in a variety of materials including plastic, chrome-plated steel, and cast iron. You get what you pay for. Plastic weights are the cheapest and are the easiest on your floors if you drop them, but they likely won’t last long as metal weights.

Iron weights are the most durable but can rust if they get damp. Before buying a set of dumbbells, ask yourself what your goal is for your home gym. Do you want something temporary or are you looking on investing in equipment that will last the rest of your life?

Heavy lifters however are probably going to have to look at a fixed dumbbell set – certainly some that cover over 50 kg that the adjustable weights go to.

A Detailed Look at the Best Adjustable Dumbbells

Generally, a more expensive set of adjustable dumbbells comes with a few extra features compared to cheaper models and likely to offer a higher maximum weight. They may also give you the ability to change weight in smaller increments and provide a simpler mechanism for changing the weight.

However, just because a set of dumbbells is more expensive doesn’t necessarily mean they are better. We’ve analysed some of the most popular sets on the market and compiled a list of the features of each. Keep reading to learn which set is best for you.

Powerblock Elite EXP Adjustable Dumbbell

Powerblock’s set allows you to change the weight by using a selector pin. The mechanism is similar to the pin system used by weight stacks on machines at the gym.

If you’re used to lifting with traditional dumbbells, it may take a few workouts to get used to the square design. However, the design makes it simple to adjust the weight in seconds, and they offer a more balanced design than traditional dumbbells.

A perk of the Powerblock set is that they allow you to increase the weight by 2.5 lbs (1.14 kg) intervals. This may be particularly useful if you’re trying to bust through a plateau. You may also find the small weight range helpful when lifting fairly lightly on an exercise like lateral raises where a small jump in weight makes a big difference.

This set maxes out at 50 lbs (22.68 kg), so for many of us, they should cover most of our dumbbell exercises except for maybe some rowing and pressing exercises. If you do find yourself close to the 50 lb limit, you can either try switching to a stricter form of the exercise or increasing your volume.

Even if these are the only piece of equipment in your home gym, you could easily design an entire workout around them. They’re also small enough that you can keep them in your closet when you’re not using them.

The compact design allows you to bring an entire wall of weights into your home. The selector pin makes switching weights a breeze so that even if you’re doing a circuit, you can set the next weight during your rest period.

Things We Like
  • Only slightly bigger than regular dumbbells
  • Allow you to change weight quickly
  • Feel natural and don’t impede you for most lifts such as biceps curls, shoulder press, and dumbbell bench press
  • Provides the option to change in 2.5-pound increments
  • Comfortable handle
Things we don’t like
  • May make a clanking noise when you use them
  • Dropping the weights may affect their durability
  • Handles may be tight if you have very large hands
  • 50 lbs might not be enough weight for you on certain lifts


Overall, these weights provide you with good value for your money and a lot of flexibility in your workouts. They’re cheaper than many of their competitors and give you the option to increase your weight by as little as 2.5 lbs. They might not be suitable for you if you have very large hands.

York Fitness 20kg Cast Iron Dumbbell Set

Adjustable dumbbells need to be easy to use and be solid. This York 20kg black cast iron set does exactly that. Easily incorporate heavier weights into your workouts with the simple twist of a sprocket. The versatility of this set makes it perfect for everyone to use. 

Things We Like
  • Easy storage and carry with included case
  • Spinlock collars are simple and can’t break
Things we don’t like
  • Manually having to change plates takes a lot of time
  • Weights only go up to 20kg, so not suitable for everyone


This adjustable dumbbell set features spinlock collars, which isn’t seen often in these kinds of sets. We love this though because it reduces the chance of internal mechanisms breaking or not working properly. The one downside of spinlock collars is that, well, they spin. So heavy curls might feel a little off balance, especially if the collars aren’t completely locked into place.

Things We Like
  • Affordable price compared to competitors
  • Easy to store when not using them
Things we don’t like
