3 Main Types of Dumbbells

If you even glanced at dumbbell reviews, you’ve noticed that they come in many shapes and sizes, which is why they’re so versatile and suitable for people of all fitness levels.

They’re proof that you don’t have to spend a lot of money to stay healthy, and you can even combine dumbbells with other equipment, like resistance bands, and you’ll get some great results.

Our performance architect and S&C movement specialist, Jacek Szymanowski, shared this:

“Hex Dumbbells are my favorite. Rubber finish won’t damage flooring, they won’t roll on the floor, which is helpful in many situations. 

Knowing the importance of Unilateral and Full Range of Motion work will help you to understand that Dumbbells play a big role in every professional athlete’s regime.“

1. Rubber Hex Dumbbells

Rubber hex dumbbells are very popular for both home and commercial gyms. They have a solid metal core with hexagon-shaped rubber-coated ends. They’re very comfortable to hold and, because of their shape, won’t roll around when they’re not being used. The rubber coating will also protect your floor from any potential damage.

2. Urethane Round Dumbbells

Known for their sleek and modern looks, urethane round dumbbells have a solid metal core that’s coated in urethane – a high-quality, durable material that (typically) has no odor. Urethane dumbbells are very easy to clean and maintain, so if you plan on sharing your equipment with someone else, these are a good choice.

3. Adjustable Dumbbells

A very convenient solution for anyone looking to switch between different weights, adjustable dumbbells will allow you to have a full set of traditional dumbbells without the clutter they would bring.

Here a few examples of adjustable dumbbells that you can find/use.

Loadable Dumbbells

Loadable dumbbells are very versatile. They consist of a handle, collars, and weight plates that you can remove or add to adjust the amount of weight you want to work with.

Dial Adjustable Dumbbells

Dial adjustable dumbbells have a dial mechanism that allows you to adjust the weight quickly and precisely. The mechanism is user-friendly, you just turn the dial to your desired weight and you’re good to go.

Handle-twist Dumbbells

If you want something easy to use, then you’re going to like the handle-twist dumbbells. You change the weight by twisting the handle to the weight you want, which makes the transitions seamless. These are simple yet efficient.

7 Benefits of Using Dumbbells

With so much gym equipment to choose from, why would you go for dumbbells? The answer is very simple: they have a lot of benefits. They’re simple, easy to use, versatile and usually a lot more affordable than most other equipment, and if you use them on a regular basis, they’ll give results just like expensive, bulky machines would. And let’s not forget they can also help you maintain and lose weight!

✅ Versatility

As far as versatile fitness tools go, dumbbells are one of the best choices you can make. You can use them to target a lot of different muscle groups, so whether you want to build strength, define your muscles, or improve your overall fitness level, there’s a pair of dumbbells that can help you with that.

✅ Balance and Stabilization

When using dumbbells you are usually engaged in unilateral exercises (you’re working with one side of your body at a time), as opposed to a barbell which is always bilateral (working with both sides of the body). Unilateral exercises (as opposed to bilateral) often engage stabilizer muscles, which are important for maintaining balance and control.

This means that dumbbells can help you improve your core strength and stability, which can improve your posture. Because of their unilateral nature, dumbbells can also help you with identifying and correcting muscle imbalances.

✅ Customized Resistance

Can you imagine working with the same amount of weight all the time? That would be terrible, right? You don’t have to worry about that with dumbbells because they come in a wide range of weight options, so you can progress at your own pace and adjust the weight to your liking.

✅ Space Efficiency

Dumbbells are compact and need minimal storage space, which makes them ideal for small spaces and home gyms. You can do a complete strength training routine with a pair of dumbbells without the clutter bulky equipment would bring. 

✅ Cost-Effective

Compared to some bigger fitness tools, dumbbells are affordable. They provide effective, challenging workouts without breaking the bank.

✅ Increased Bone Density

Weight-bearing exercises improve bone density, reduce the risk of osteoporosis, and promote overall bone health. With dumbbells, you can take these exercises to the next level. 

✅ Mental Health Benefits

Dumbbells are simple to use and there’s a ton of workouts you can include them into. Regular exercise is great for your mental health, releases endorphins, and reduces stress.

How to Choose the Best Dumbbell?

With them being so popular and so widely used, there’s an incredible amount of different dumbbells on the market. Making the choice can seem difficult, but if you pay attention to a few key characteristics, you’ll see it’s a piece of cake.

1. Durability

You want something that will last a long time and that you’ll be able to use however you want, without being extremely careful. Look for dumbbells made of high-quality materials, like steel, iron, and rubber coating.

2. Comfort in Use

Comfort is very important, because if the dumbbell isn’t comfortable, it will be distracting and you won’t be able to get the most out of your workout. Your best option is always a dumbbell that has an ergonomically designed handle, since it’s comfortable and reduces some of the strain placed on your hand and wrist.

3. Shape

Hexagon, round, square… There are all kinds of shapes the dumbbells come in. The shape is an important feature, because it will impact stability, storage, and rolling, so think about what is most important to you and what suits your workout space the best.

4. Grip

You want a secure and comfortable hold on the dumbbell, so the grip quality of the handle is one of the most important things to think about when it comes to choosing your new dumbbells. Your best bet is a knurled or textured handle that has a non-slip grip.

5. Material Quality

High-quality materials, such as cast iron or steel, contribute to longevity and durability because they won’t degrade over time. Don’t cheap out and get dumbbells that are made of low-quality materials because they’ll fall apart soon.

6. Space-Saving Feature

If your workout space isn’t huge (and when it comes to home gyms, it usually isn’t), think about options that will save you space, like adjustable dumbbells or sets with a rack. They can replace multiple sets of traditional dumbbells and they’re ideal for home gyms with limited space.

The Olympic champion, Oleksiy Torokhtiy, noted:

“I like adjustable dumbbells, they take up less space and are great to have even at home.“

7. Weight Options

Check the weight range before deciding on what to buy. You want dumbbells with weight increments that not only suit your current fitness level but also allow you to progress. It’s always best to have dumbbell sets for a home gym because they’ll allow you to progress.

These dumbbells have a standard hex shape and are sold in pairs, so you get a good bang for your buck. Their construction is good quality and robust (as if we expected anything less from Rogue) – they’re made of steel, the handle is chrome-plated, and the head is rubber-encased.

The steel handles are chrome-plated and ergonomic, so your grip is secure and comfortable.

They start at 2.5 pounds and go all the way up to 125 pounds – a substantial weight range that provides a lot of versatility. There are also a lot of weight increments that allow you to gradually increase the weight as you progress.

These dumbbells have dimensions based on weight, with length, width, and height all adjusted to accommodate the different sizes. The handle diameter is also tailored to the weight of the dumbbell: those up to 10 pounds have a 0.98’’ handle, and those of 12.5 pounds and heavier have a 1.37’’ handle.

These are the best free weights for a home gym, and they have everything you want: they’re durable, have plenty of weight increments, and provide a ton of versatility for your workouts.

Dumbbell vs Barbell vs Kettlebell: Key Differences

All of these are popular, and you may be tempted to use them all. You can, of course – there’s no sense in limiting yourself and focusing on just a few pieces of equipment and never changing your routine. However, it’s good to know what you’re getting yourself into, because each of these weights has its own pros and cons.

Take dumbbells – they’re compact, versatile, and allow you to do a wide range of exercises and target different muscle groups. They’re also excellent for isolation exercises because of their precision and are ideal for beginners. Dumbbells are usually a staple in any home gym, and you’ll have a hard time finding one that doesn’t have at least one pair of dumbbells.

Barbells are longer and heavier than dumbbells and excel in compound movements, like squats, deadlifts, and bench presses. They promote overall strength and muscle development, so it’s no wonder they’re so popular with powerlifters and serious bodybuilders.

When you’re using a barbell, you’re using both hands, and that engages more muscle groups, which results in greater gains in less time. The thing about barbells is, they require proper fork and technique to prevent injuries, but in general, barbells will allow you to lift greater weights than dumbbells will.

Our expert, Sergiy Putsov, confidently stated:

“In my experience, dumbbells excel in exercises that require a greater range of motion and individual arm work, such as unilateral movements, incline bench presses, flyes, lateral raises or single-leg exercises, where they provide improved stabilization, muscle symmetry, and targeted muscle engagement.“

The most unique when it comes to design are kettlebells. A kettlebell is basically a handle with a weighted ball and it’s perfect for dynamic movements that improve strength and cardiovascular fitness at the same time.

Kettlebell swings, Turkish get-ups, and snatches engage multiple muscle groups and can do wonders for your endurance, mobility and balance. Kettlebells are known for their functional training benefits, and, if you want a whole-body workout, you can’t go wrong with them.
