Surely you’ve had a hard day at work and the last thing you want to do after work is go to the gym, right? It’s in those moments when having a gym at home is very useful and a piece of equipment that must be, yes or yes, in it are some adjustable dumbbells.

They are very easy to adapt to your training needs, take up little space in your home, and, in the long run, will save you money on the purchase of equipment. If you’re thinking about getting one, here’s what the best ones are, what types there are, and how they differ from stationary dumbbells. Let’s go for it!

What are adjustable dumbbells and how do you use them?

Adjustable dumbbells are personal training equipment that allows you to add or remove weight with great ease. As the name implies, they “adjust” to your training routine. It doesn’t matter if you are a beginner in the world of training or an accomplished fit, because they will help you take your workouts to the next level.

With them, you can work multiple areas of the body, as there are exercises with dumbbells to strengthen the back, arms, shoulders, and even the abdomen. In short, they are quite versatile, and using them in your routine can help you give more stability to your joints, gaining power and resistance.

Types of adjustable dumbbells and their use

When talking about the best adjustable dumbbells we find two main groups: the first, are the traditional adjustable dumbbells that consist of a bar with weights on the sides. These have a nut or metal clip that you can remove to change the weight to your liking, putting it back to start doing your exercises.

They are relatively inexpensive and there are models on the market that allow adaptation to high weights, over 30 kilograms. On the other hand, they require a little more time to adjust.

The second type of adjustable dumbbell is the dial or synchronized dumbbell, whose main advantage is the ease of changing the weight. They come with a base and all you have to do is put the dumbbell there, select the desired weight with the lever or wheel and that’s it; they will add or remove the indicated discs in a matter of seconds.

They are perfect if, for example, you are doing a trapeze routine with dumbbells and want to move on to a biceps or triceps routine without wasting much time. Their weak point is that they are more expensive than the traditional ones.

Differences between the best adjustable dumbbells and the fixed ones

It may seem like a no-brainer to say it, but what distinguishes adjustable dumbbells from the typical fixed ones is that the former allows you to change the weight, while the latter doesn’t

Just as adjustable dumbbells have types, so do fixed ones, and we’ll tell you the distinctions between those most important classifications with the adjustable ones. Of course, leaving aside the point of weight exchange, which we already told you about.

  • Hexagonal: what makes these dumbbells stand out is their hexagonal shape at the edges, so they don’t roll on the floor, unlike most adjustable dumbbells whose discs are round. Another highlight is that they usually come with a rubber coating, something that not all adjustable dumbbells have.
  • Vinyl and neoprene: both vinyl and neoprene dumbbells have a cast iron core, do not usually exceed 10 kg in weight, and have a glossy coating on the former and a matte coating on the latter. While the adjustable ones can reach higher weights, such as 30 or 40 kg, and their manufacturing material is very variable; from chrome-plated steel to sand.
  • Urethane: the most important difference between them and the adjustable dumbbells is in their durability; urethane is a material that is very resistant to blows, falls, and even the weather. Adjustable dumbbells, on the other hand, are not all as durable. For example, cast iron dumbbells require protection against rain, otherwise they will rust.

What should you look for when choosing the best adjustable dumbbells?

Many people think that when it comes to buying the best adjustable dumbbells, the most important things are points like price or brand, but that’s not entirely true. If you ask us, we consider three key factors to make a good choice.

  • Weight range: by this, we mean the maximum and minimum kilograms you can set on the dumbbell. This will vary based on the workouts you usually do. For example, if you are starting with exercises to gain strength with dumbbells, ideally you can adjust them from one to 10 or more kg. You should also pay attention to the number of “steps” allowed if it’s every two or more kg.
  • Ergonomics: as you are going to have them in your hands, it’s important to choose dumbbells with a comfortable grip, to avoid accidents and discomfort. Look for a model that has a non-slip handle and some even have padding for greater comfort.
  • Manufacturing materials: the best adjustable dumbbells are made of durable materials, such as galvanized steel or cast iron. There are also models that have some rubber coating on the weights to avoid damaging the wooden floor or the one you have in your home if they fall.

How safe are adjustable dumbbells?

One of the most common doubts about the best adjustable dumbbells is if they are safe for workouts and the answer is yes, but you must take your prevention measures to avoid any incident. For example, in the traditional ones you have to tighten the adjustment nuts very well, so that the discs do not move.

While in the dial dumbbells, you must make sure that the dumbbell fits well on the plate. Then, they do not allow the removal of the base until the selected discs are adjusted, as a safety measure.

As for the operation in your routines, it’s the same as you would have with a common fixed dumbbell. You can do floor push-ups, CrossFit, bench presses, in short, all the exercises you do normally, but with dumbbells that take up less space and are more versatile.
