Adjustable dumbbells have revolutionized home workouts. With just one pair, you can replace an entire rack of traditional dumbbells, saving space, time, and money. If you’re building a compact home gym or simply want more flexibility in your workouts, understanding how adjustable dumbbells work is crucial.
In this 2025 user guide, we’ll explain how these versatile weights function, the benefits they offer, and help you decide if they’re the right fit for your fitness routine, as well as share with you some links on where to get them from.
How Do Adjustable Dumbbells Work?
At their core, adjustable dumbbells allow you to change the weight on a single handle without needing multiple individual dumbbells. They typically operate through one of several key mechanisms that we have shared with you in details below:
a. Dial System
This is the most popular mechanism used by brands like Bowflex and NordicTrack. You may need to get some guidance on its working ability so to give you the benefit of the doubt, here’s how it works:
- Turn a dial at either end of the dumbbell to select your desired weight.
- The dial connects to a locking system that picks up the required number of weight plates.
- Lift the handle, and only the selected plates come with it, leaving the rest behind.

b. Pin or Selector System
Slide a pin or lever to the selected weight, similar to gym machine stacks. Once adjusted, only the chosen weight plates are lifted when the handle is picked up. This helps the one enaged in the routine to be able to use the same equipment for different weightlifting purposes without necesserily having to purchase extra.
c. Twist-Lock or Turn-Grip Mechanism
Rotate the handle itself to change the weight. This turns an internal locking system that connects with the correct weight plates. These systems ensure a fast, smooth transition between weights ideal for interval or circuit training.
