Best Adjustable Dumbbells Under 250 - Flybird Adjustable Dumbbells
Brand: Flybird | Weight Range: 5 - 25 lbs Per Dumbbell
These Flybird Adjustable Dumbbells looks like a popular choice, and it's easy to see why.
First off, they're designed simply and actually look quite stylish in comparison to some of the other dumbbells on the market.
Secondly, they're light! Up to 25 lbs or 11 kg isn't that much for someone advanced, however, for many stepping in to fitness for the first time it can be a decent amount of weight to allow for some progression.
We'd say for beginners, who want to save some space, and potentially those who enjoy lighter workout and prefer to apply weight to dynamic whole body exercises (like a weighted lunge for example) these Flybird Adjustable Dumbbells could hit the mark.
And at the price...it won't break the bank either.
Best Adjustable Dumbbells All-rounder - Bowflex SelectTech 552
Brand: Bowflex | Weight Range: 5 - 52.5 lbs
Bowflex is practically a household name in fitness, and they make some seriously high quality and impressive exercise equipment.
These Bowflex SelectTech dumbbells cover all bases and all levels of fitness, so when you invest in these you'll find that even when you advance in strength, you'll have enough weight to help you progress.
Each dumbbell can have between 5 lbs to 52.5 lbs, which makes it great for beginners getting used to core compound movements (dumbbell press, dumbbell row etc), and decent for advanced gym-goers for supersets, isolation exercises and even multi-plane dynamic workouts (we're looking at you crossfitters!)
If you're committed to fitness and want to buy something once that you'll have for years to come, these Bowflex SelectTech dumbbells could be a good way to go.
Best Adjustable Dumbbell Alternative - POWERBLOCK Elite EXP
Brand: Powerblock | Weight Range: 5 - 50 lbs
Powerblocks serve a very important role within the adjustable dumbbells ecosphere, and one that is vital if you train a certain way...
Much like some of the best dumbbells available, having a design which allows the dumbbell to not rock or slip can be important to training with confidence with specific exercises.
Arguably more for advanced trainers, dumbbells like the Powerblock Elite EXP allow for you perform exercises without needing to let go of the weight.
Picture holding these, pressing over your head, then grounding them, doing a push up, jumping back up...you get the idea!
Thanks to their large box design and flat sides, you can do this confidently without risking any movement which may get in the way of the workout.
For more athletic styles of training, we'd say these Powerblock Elite dumbbells could be a good call.
Best Adjustable Dumbbell High End - BODYTECH x NUOBELL
Brand: BODYTECH x NUOBELL | Weight Range: 5 - 50 lbs
If you're looking for something that fits in with a minimal aesthetic and also has a distinct advantage over most adjustable dumbbells, then the Bodytech x Nuovell collaboration could be worth looking into.
Asides from its frankly stunning design, this dumbbell allows you select the weight you need but without pulling the 'empty slots' with it.
This a definite plus point as it allows for a smaller dumbbell at lighter weights, which in turn means you can move them around in a more natural way in relation to the weight itself.
If you're looking for something super high end, then the Bodytech x Nuovell adjustable dumbbell may be up your street.
How To Pick The Best Adjustable Dumbbell?
Picking the best adjustable dumbbell can be a little tricky, and potentially an expensive trial and error process if you get it wrong.
Here's our two cents on some of the most frequently asked questions.
Are adjustable dumbbells worth it?
Yes, if you want to save space and don't fancy having weight plates everywhere, which is arguably what you're paying a premium for.
Weight plates don't just require space to store, the constant removing and loading can increase chances of scuffs on the floor and even pose trip hazards when improperly placed.
Adjustable dumbbells get rid of practically all that hassle, but more often than not at a more premium price range.
Why are adjustable dumbbells so expensive?
A few reasons come to mind, but really, it's down to the engineering, weight and functionality within the dumbbells themselves.
There are dials, loading bases, dense small form factor weight plates, some even have a digital element!
All of these add together for something that costs more to make than a simple dumbbell, and therefore packs more a punchy price tag.
