How Do Adjustable Dumbbells Work?

There are currently three options for adjustable dumbbells in the market: sliding pins, rotating dials, and screw-lock dumbbells.

The systems allow you to set the weight that you want between sets. While adjustable dumbbells are designed to save space, the designs also aim to make the weight change process easy and efficient so you can have a quality workout without difficulty.

You do not want to waste time changing weights between each exercise, and you do not want fixed weights to clutter up your home.

Hence, adjustable dumbbells are popular for every level of trainee who wants to work out at home.

Pros and Cons of Adjustable Dumbbells

The biggest strength of adjustable dumbbells is the compact design. A pair can replace fifteen or more sets of fixed dumbbells.

While adjustable dumbbells are more expensive than the traditional kind, you will save more since you do not have to buy multiple pairs.

You can quickly change the weight up or down depending on the exercise you are doing. That’s why it’s useful to have them when you are doing super-sets, and you want to minimize the rest time.

While the higher price tag may be a con for most home users, it is cheaper to invest in a good pair of adjustable dumbbells. As you develop more strength and muscle, you will need heavier dumbbells, and that will add up.

There’s just one true downside to owning an adjustable dumbbell; they have more parts than a fixed one, which means they have more breakable parts. You may have to take more care when using adjustable dumbbells.
