How Do Adjustable Dumbbells Work? (& How To Adjust Them)

Adjustable dumbbells are one of the most versatile pieces of equipment you can own. They’re a great way to get more use out of your workout space, as they let you perform a wider range of exercises than just running up and down the rack at the gym. 

But have you ever been left wondering, “how do adjustable dumbbells work?” Today we’re going to help answer that question for you and help you decide whether a set of adjustable dumbbells are worth considering for your home gym. 

An adjustable dumbbell, also called a "selectorized" dumbbell, is specially designed to allow a user to change the weight of the dumbbell by adding or removing plates. 

Adjustable dumbbells are a space-saving, time-saving, and cost-saving solution. With adjustable dumbbells, you can get the same workout as you would with a complete set of dumbbells with just a single set. 

Not only are they far more cost-effective than buying multiple dumbbells, but they also make it easier to quickly switch from one exercise to the next. 


Benefits of Investing In Adjustable Dumbbells 

Better For Home Use 

Adjustable dumbbells are great for at-home workouts because you can adjust the weight as your fitness improves and you get stronger. With traditional dumbbells, you have to buy an entirely new set. With adjustable dumbbells, you can keep using the same pair and just adjust the weight. 

Compact And Space-Saving 

Dumbbells are a garage gym essential, but they can take up a lot of space. The biggest advantage of adjustable dumbbells is that you just need a single set. This means they can easily be stored and take up far less space than the traditional alternative. 

Safer Exercises 

Dumbbells are safer than barbells because they allow you to work out without a spotter. If you lift barbells alone, there are times when you’ll need a spotter to help you with the heavier weights. If you work out alone at home, dumbbells are the way to go. 

Portable & Versatile 

Adjustable dumbbells are a versatile piece of equipment that can be used for a variety of exercises, and they’re a great addition to any home gym. They give you the ability to increase your strength and build your muscles without having to be restricted to the number of weights that you have. 

Because of their compact size, these dumbbells are so easy to stow in the trunk of your car. For avid travelers, or those who don't have a home gym, travel workouts are a great way to stay active—and these weights make it easy. They won't take up any room in your luggage and can be taken anywhere you go: hotel room, outdoors, or an empty field.
