Core Fitness Adjustable Dumbbells are a bit similar to the StairMaster TwistLock set that we’ve previously reviewed here. Their design and features is almost the same TwistLock adjustment system, weight range, and weight increments. They’re different from the Bowflex SelectTech 552 as instead of twisting any side knobs to adjust them, you simply twist the handles. No doubt, there’s a lot more to be said with regards to these selectorized dumbbells, though, and in this review of Core fitness dumbbells for sale, we’ll try to cover each and every important aspect.

Core Fitness Adjustable Dumbbells
Dumbbell construction
The construction of these core home fitness adjustable dumbbells are made from metal and plastic. To start with, the weight plates are produced from steel, but they’re coated with a layer of durable, high-impact material. This particular area comes with pluses and minuses. In simpler terms, plates won’t rattle on the handles; they won’t rust and will make you feel good. But, if you continuously drop them on a hard surface such as concrete, the PVC coating, even though it’s long lasting, will eventually crack.
These being said, just as for any other selectorized dumbbells, it’s recommended to use them with extra care. Also, even though they can support exercises as push-ups, these are not recommended.
Made of steel, the handles are coated with a layer of rubber, with an arched layout. So, the handles offer you a comfortable, sure-grip, reducing damage to the hand. Plus, the rubber material comes with better adherence, even if your hands are sweaty. So, the handles are simple to turn, in order to adjust the weight.
The Core Fitness adjustable dumbbells aren’t so much larger than fixed, hex dumbbells. With all the weight plates attached, their length is approximately 14″ (35.5 cm), while their width is approx. 7.5″ (19 cm). In other words, their complete length is the same as the length of a 50 lbs hex dumbbell.
The plates are kind of wider than for a 50 lbs standard hex dumbbell, but on the other hands, these dumbbells are said to be less bulky than the Power Block Elite 70.
Increments and Adjustment system
The Core Fitness adjustable dumbbells review reveal that they feature the same TwistLock adjustment system as the StairMaster TwistLock 100. To adjust the weight here, you need to place them on cradles, twist the handles until the desired weight is achieved, and simply lift them up. Once a certain weight is set and a dumbbell is lifted from its cradle, the handle will just pick up the appropriate weight plates, the other remaining into the cradle. The cradles really feature small “keys” that unlock the handles and allow them to be twisted.
Every weight plates, except the 2.5 lbs (1.13 kg) ones, are circular, similar to the classic, cast iron weight plates. So, as you twist the handle, the primary axle extends, picking them up. This being said, the ends of the handle actually enter the weight plates; so the plates cannot fall off, as they don’t connect to the handle via any additional plastic parts. Also, the plates also cannot spin on the axle, as they lock up together.
When it comes to weight area, the handle without any plates weighs only 5 lbs (2.26 kg). The first plates weigh 2.5 lbs (1.13 kg) each, while the rest of the plates weigh 5 lbs (2.26 kg) each. In other words, the Core Fitness dumbbells offer a weight range of 5-50 lbs (2.26-22.6 kg) each, with the following possible weight settings: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50 lbs (2.26, 4.5, 6.8, 9, 11.3, 13.6, 15.8, 18.1, 20.4, 22.6 kg).
There’s one setback of the weight set by affordable dumbbells that should be mentioned here though, regarding the adjustment system of the Core Fitness dumbbells for sale. Weight adjustment per side of dumbbell can only be equal. As you twist the handle,. Both its ends will adjust by the same length, picking up the same number of plates. So, you need not create an off-set eight, in case your workout regimen demands it.
Cradles
The storage cradles are an important accessories for the fast weight adjustment for these dumbbells. They’re actually needed, as you cannot adjust the dumbbells without them. They’re made of an PVC/aluminium combo, boasting of openings at each end, in order to provide a secure grip when moving them with the dumbbells on top. They’re approximately around 16″ (40.8 cm) long, and 9″ (23.2 cm) wide.
Even better as the cradles can be mounted on a stand, accessory which does not come with the set. This stand is approx. 30″ (76 cm) tall, and makes the adjustment and pick up of the dumbbells much more convenient.
