Definition of adjustable and fixed dumbbells
Adjustable dumbbells are pieces of weightlifting equipment that allow you to adjust the weight of the dumbbell by adding or removing weight plates to the handle. They're the Transformers of weightlifting equipment, akin to having a whole gym in one compact and convenient package at your fingertips.
Fixed dumbbells, or standard dumbbells if you will, have, as the name suggests, a fixed weight that cannot be adjusted. They come in different sizes (the heavier, the bigger) and shapes. Round, hexagon, square, you name it.
Advantages of using dumbbells for strength training
Dumbbells are a versatile piece of equipment that can be used to train almost every muscle group in your body. They offer a range of motion that mimics natural movement, making them great for functional training. Compare that to a weightlifting machine, where the range of motion is fixed.
So, let's jump right into the comparison of adjustable vs fixed dumbbells.
1. Weight range
The weight range of adjustable dumbbells compared to fixed models is the same when talking about the entire weight range, from light to 50 kg/100 lb at the top end. Both types of dumbbells offer low weights from 1 kg /2 lb up to 50 kg / 100 lb, and all the weights in between.
Increments
Adjustable dumbbells have weight increments of 1,5–2 kg, from the lowest to the highest. Fixed typically have increments of 1 kg in the lower weight span. The steps usually tick up in 2,5 or 5-kg increments when the weight increases past that.

4. Storage and transport
Storage
Adjustable dumbbells are a game-changer if you have limited space in your home gym (read: lounge). They come with a stand or case that easily stows away in a closet or under the bed. Fixed dumbbells, on the other hand, require more space and a dedicated weight rack, which can take up more space than your pet elephant (he is cute, though, and you should see him water the plants).
Transport
First up, adjustable dumbbells. These sleek and versatile beasts are designed to make your life easier. Need to take them to the park for an outdoor workout? No problem! Adjust the weight to your desired level and secure the plates in place.
Now, let's move on to fixed dumbbells. Want to take them along for a workout session? Not a problem if you plan to use only one or two pairs of different weights. But if you need a range of weights for a full-body workout, you'll have to bring multiple sets or your elephant helper. Bulky? Hey, he's trying to slim down! Oh, the weights. Yes. They're weighty, alright.
1. Hexagon
Hexagon dumbbells are a type of weightlifting equipment shaped like - you got it - a hexagon, with six sides, rather than a traditional round shape. The hexagon shape helps prevent the dumbbell from rolling away and provides a more stable base for exercises such as push-ups, renegade rows, and other activities where the dumbbell sits on the ground. Hexagon dumbbells come in various sizes and weights, from small 4-pound dumbbells used for light exercises to very heavy ones used for strength training.
+ stays in place when it gets put down on the floor
+ won't break as easily when hitting the floor due to one fixed weight on each side
- can "bounce away" when dropped to the floor
2. Round shape
As the name implies, round dumbbells are fitted with circular weights, with two equal-sized weights on either end of a central handle. They are typically cast iron but can also be made of steel, rubber or other materials.
Round dumbbells come in various sizes and weights, from small 1-pound dumbbells used for light exercises to very heavy ones used for strength training. They can be used for a variety of exercises, including bicep curls, tricep extensions, shoulder presses, chest presses, squats, lunges, and more.
+ Easy to use without feeling too "big" due to their sleek shape
+ Well balanced when in use due to the balance on each side
- Can easily roll away when you put them down on the floor
3. Square shape
Square dumbbells are relatively uncommon, with four equal sides and two equal-sized weights on either end of a central handle. They are typically made of steel or iron and can be coated in rubber or urethane for protection and grip. Squared dumbbells come in various sizes and weights, from small 5-pound dumbbells up to 90 pounds for the more experienced user.
+ Often adjustable weights
- Uncomfortable to use for your wrists
- Can feel big to use in concentrated exercises, like biceps curls or triceps extensions
8. Versatility
a) Ability to adjust weight for different exercises
When it comes to versatility, adjustable dumbbells are like the chameleons of gym equipment - they can adapt to any exercise and any level of improvement. They offer the flexibility of adjusting the weight for different exercises, which can be especially beneficial if you're doing circuit training. Fixed dumbbells, on the other hand, don't adapt, so you need a whole set to get a well-rounded workout.
b) Adaptability for different workout routines
If you get bored quickly with the same workout routine, adjustable dumbbells are like a new best friend who knows all the cool moves. They are versatile and can be used for a variety of workout routines, from strength training to HIIT workouts. Fixed dumbbells, on the other hand, are limited to the weight they come in, which can limit your workout routines and creativity.
c) Ease of use and transition time between exercises
When it comes to ease of use, and transition time between exercises, the right pair of adjustable dumbbells are the Swiss Army Knife of home gym equipment. They're easy to use and allow you to adjust the weight between exercises quickly. But don't be fooled. Not all adjustable dumbbells work in the same way. So make sure you choose a model that offers quick weight adjustment.
9. Range of motion
Both adjustable and fixed dumbbells may pose a range of motion limitations, the main one being the size and shape of the dumbbell itself. The extent of these limitations will depend on the specific brand and model of the dumbbell, as well as the exercise being performed and the user's body type and mobility. In addition, certain exercises may be limited by the range of motion allowed by the shape. For example, if the dumbbell is too bulky or irregular, it may be difficult to perform exercises that require a full range of motion, such as dumbbell flys and triceps extensions.
Choose a sleek shape
Hence, it's crucial to select dumbbells with as sleek shape as possible that enable a full range of motion for the exercises you plan to perform. One other thing to consider when talking about range of motion for adjustable dumbbells is the size of the dumbbell at different weights. When setting a lower weight, you want the dumbbell to be no bigger than it needs to be. Some models are the same length no matter the weight you load, and that may lead to difficulties when performing certain exercises.
Preferably, you want to look for an adjustable dumbbell that is as small as possible in low weights and then gets bigger only when you add weight:
10. Safety and Risk of Injury
Stability and balance
If stability and balance are top of mind, fixed dumbbells could have the upper hand over adjustable models as they are made from solid metal, like the old oak tree in your backyard (except trees are wooden, but you get the point!). Adjustable low-quality dumbbells may wobble or shift during use, which can lead to injury if not used correctly.
However, adjustable dumbbells usually have safety features, such as locking mechanisms, to prevent accidents. And the higher quality of the dumbbell, the more probability of a safe locking mechanism.
In any case, using the dumbbells correctly and safely is essential to prevent accidents. Remember, your safety is more important than how much weight you can lift.
11. Fitness Goals and Personal Preferences
Matching dumbbells to fitness goals
Meeting your fitness goals is how you progress with positivity. To keep those high fives coming, adjustable dumbbells act like your personal fitness genie - they can grant your every wish (within reason, people!). Adjustable dumbbells offer more versatility and flexibility, which can be beneficial if you're doing circuit training or have a variety of fitness goals. Fixed dumbbells, on the other hand (excuse the pun), are more specific to certain exercises and can be beneficial for those with more specific fitness goals or the need for only a few different weights.
Personal preference
Personal preference is also a factor when choosing between adjustable vs fixed dumbbells. Some people prefer the convenience and versatility of adjustable dumbbells, while others prefer the simplicity and durability of fixed dumbbells. Choosing the type of dumbbell that suits your preferences and fitness goals is essential. Think of it like choosing between ice cream flavors - both might be delicious (except pistachio - you know I'm right), but it depends on your taste.
12. Considerations for fitness level and experience
Your fitness level and experience also play a role in choosing between adjustable vs fixed dumbbells. However, it's not as easy to say that one type of dumbbell always fits just one fitness level.
Both adjustable and fixed can suit both newbies and experienced athletes alike.
fixed dumbbells if you
- only have a few specific needs of the weights
- know that you won’t need to frequently change weights
- want to be able to throw the dumbbells on the floor
- need a super heavy dumbbell (>50 kg) that is not attainable for adjustable dumbbells
Conclusion
In conclusion, choosing between adjustable and fixed dumbbells can be tough. They both have their unique benefits and advantages. Focus on what works best for you. After all, choosing the right equipment is a personal decision – it's all about what makes you happy and satisfied.
While adjustable dumbbells are often more expensive upfront, they are generally a more cost-effective option, given how many in-built weights they come with. And that adaptive nature saves you money compared to buying a complete set of fixed dumbbells in different weights. However, adjustable can be more expensive if you only need a few pairs of different weights.
