As far as strength training goes, dumbbells are usually the first equipment that most people go for. While having a set of dumbbells at home allows you to engage in several exercises for building muscle and strength, they still take up space. Plus, once you become accustomed to their maximum weight, you’ll have to buy a new set of dumbbells with heavier weights if you want to keep increasing your strength. A better alternative is to invest in a set of adjustable dumbbells. This type of dumbbells features a special design that enables you to seamlessly adjust their weight based on your strength and personal needs, allowing you to target various muscle groups and perform a wide range of exercises with a single set of dumbbells. For those looking for an adjustable dumbbell set that’s easy to use and built to last, the Ativafit DT1166 is a great option.
The Ativafit DT1166 is an adjustable dumbbell set that offers smooth weight adjustments for diverse strength training, which features a contoured, textured, soft grip handle, all-steel weight plates, and a proprietary Dailtech design that allows you to effortlessly switch between 12 different weights ranging from 11 to 66 lbs. in 5 lb. increments with a simple twist of the dial.
Built to endure even the toughest workouts, this adjustable dumbbell set enables you to release stress, build muscle, and increase your strength without taking up too much space.
Here’s our review of the Ativafit DT1166, where we have a more detailed look at it and explain how this adjustable dumbbell set is designed to work.
DESIGN & SPECS
Starting with the dumbbells’ size, these adjustable dumbbells have a noticeably small footprint, with each dumbbell measuring just 16.3 inches long by 7.9 inches wide by 8.3 inches tall (when accounting with their base for storage), only taking up the space of a shoe box.

Their space-saving design replaces multiple bulky dumbbell sets, making them the ideal choice for home gyms of any size
The Ativafit DT1166 also pack a premium construction that’s built to last. They’re crafted with high-quality plate-holding inner discs made entirely of metal, and come equipped with sturdy, laser-cut, all-steel weight plates, making them significantly more durable than other dumbbells on the market that are made of cheaper materials such as rubber or plastic.

Each of their weight plates is shaped with precise laser cutting, and then welded together with a rivet that makes transitioning between different weight levels incredibly smooth.
Not only that, but these adjustable dumbbells also come equipped with a contoured, textured, soft grip handle with a honeycomb structure, which makes them comfortable to hold and provides a great grip all around, even for the toughest workouts you can think of, while also preventing odor from forming.

What’s more is that they also feature a proprietary Dailtech design, which allows you to effortlessly change their current weight between 12 different weight levels ranging from 11 to 66 lbs. in 5 lb. increments with a simple twist of the dial.

This clever weight-adjustability function makes this adjustable dumbbell set ideal for not only performing basic body workouts, but also core fitness drills, and even exercises that focus on developing specific muscle groups.
HOW TO USE?
To adjust each dumbbell’s weight, simply press and hold the lock button on the inner side of their weight plates, then rotate the dial wheel on the outer side to your desired weight level.

Then, just release the lock button and you can start your workout.
