When purchasing a set of adjustable dumbbells, it is important to consider several factors.

With the Stairmaster twist and lock, you will find various quality features, simple design, and ease of adjustment, which makes it easy to get in a workout, and easy to build up muscle in less time.

Quality

Contoured grip, soft grip handles, and an aluminum cradle, ensure an adjustable set that is going to last.

Textured handles also ensure a comfortable grip, so as to avoid dropping, or other issues when working out. A heavy, outer body, also makes these ideal for any type of workout you are going to engage in.

Weight range & increments

With the set beginning as light as 5 pounds, and going up to 100 pounds, you can get a great workout, in no time. Adjustment increments go in 5 pounds, making body building, or a simple workout at home, something easy to do.

And, you never have to take your hand off of the weight, in order to adjust; just place on the base, twist, and lock it in to place.

Ease of changing weight

Changing the weight increments with this system is truly seamless, and easy for even the novice to do. It is simply placing the weight on the rack, and twisting it in to place; you never have to remove your hand off the weight to adjust the weight.

You can clearly see the color increments, so that you know how many pounds you are adding on at a time, and so as to ensure you are only putting on the amount of weight you can handle.

Handle

The handle and grip are comfortable, and with a contoured grip, any user’s hand is going to make its way around easily, for any workout that you are going to do.

The size of the dumbbell is also similar to other single ones, making it quite easy to grip, and perform a quality workout, in no time at all.

Customer Reviews 

There are great customer reviews with this product. The main being that changing the weight is literally seamless, and takes only a second to twist and lock in to place.

The lock mechanism is also very safe, so you do not have to worry about the weight dropping when you are doing a workout.

Although there are great reviews, one review said the set is not built to last; after owning it for just over one year, they began to have trouble doing the workout, and adjusting the set in to place.

With several features, and the ability to lock the weight in to place, quickly and in less than a second, it is truly a device to consider investing in. The affordable price tag is also an appealing feature.

It does have a couple of negative reviews about quality, but for the most part, customers seem to like the design, style, ease of use, and the safety features that are built in to place, with this adjustable weight set from a top name brand.
