Not only this, but they look great and feel sturdy too — what’s not to like?

The innovative JAXJOX DumbbellConnect can improve your home workouts immeasurably, helping you build muscle and burn calories while saving you time, space and money. How do I know this? Because I got my hands on a pair and pitted them against some of the best adjustable dumbbells (opens in new tab) currently on the market in a series of rigorous tests.
Safe to say from that introduction, I was impressed by the self-professed world’s first digital dumbbell. Their clever weight-changing mechanism meant I could make the dumbbells lighter or heavier in seconds, with minimal effort, making them ideal for putting the progressive overload (opens in new tab) principle into practice. And, with each dumbbell offering eight weight options from 8lb-50lb (all contained within one compact package) there’s something to suit lifters of most experience levels.
They look great too, setting themselves apart from the customarily bulky adjustable dumbbell aesthetic with their slim, rounded plates, classy matte gray finish and sleek profile that makes them more wieldy than most.
They have to be charged up using loading docks to work, which is a slight annoyance, but this is minimized by the fact that a full tank lasts upwards of five days.
So, despite being infinitely fond of my fixed weight hex dumbbells, the efficiency of these adjustable alternatives has seen them force their way into my at-home fitness routine. Read on to find out why I think they should be part of yours too.
The JAXJOX DumbbellConnect’s MSRP — $499 on the brand's website or £390 at Argos in the UK — may raise a few eyebrows at first. But there’s more to this price than meets the eye.
You get the equivalent of a dumbbell rack (eight pairs) worth of free weights, ranging from 8lb to 50lb, while only taking up the space of a single set. When just one 50lb Amazon Basics Hex Dumbbell (opens in new tab) can set you back more than $71, the JAXJOX option starts to look more price-savvy — particularly given they come as a pair. It’s also worth keeping an eye on online retailers for discounts.
They save you from the clutter of umpteen dumbbells lying around your home gym space too, while allowing you to quickly and effortlessly up the weight as your strength improves to ensure your training doesn’t plateau.
Each of these adjustable dumbbells offers eight different weight settings; 8lb, 14lb, 20lb, 26lb, 32lb, 38lb, 44lb and 50lb. This will cover most bases for beginner to intermediate lifters.
The 6lb increases are good for incrementally increasing the load you’re lifting for different exercises as your strength increases, without upping the load so much that your form falls apart.
The JAXJOX DumbbellConnects are far and away the most polished pair of adjustable dumbbells I’ve tested. Where most of their competitors are bulky with notable gaps between the interchangeable metal plates, the DumbbellConnect’s weights sit flush against each other to give a neat, sleek and sturdy finish.
There was none of the usual rattling when I pressed them overhead, inspiring total confidence in the security of the plates, and the smaller dimensions of the dumbbells meant I was able to complete everything from bicep curls to goblet squats without them getting in the way — not the case with more awkwardly-shaped rivals like the Ativafit Adjustable Dumbbells (opens in new tab).
The plastic docking stations also feel well-made, and have the same stylish gray finish as the dumbbells along with a green trim. This gives them a sporty aesthetic that slipped seamlessly into my home gym. The screens on each station that displays the current weight on the bar are simple but effective, with up and down buttons on either side so you can change the load with ease. They can be a bit tricky to see if you store the weights on the floor, as they’re positioned on the foot of the base, but that’s our only real design gripe.
Set-up and features
Setting up the JAXJOX DumbbellConnects didn’t take me long at all; you just need to place each central dumbbell into one of the docking stations then slide the plates into place in any order. The docks do have to be charged up to change the weight so you may want to store them near a mains outlet, but a few hours of juice should keep them going for over five days (even with fairly consistent use).
When it comes to features, these digital dumbbells go much further than your average free weight. As I’ve already covered, you get eight different weight options and the ability to flit between them by loading the dumbbells into the docking station and toggling through the options using the up and down arrows on the base, but that’s not the only trick up JAXJOX’s sleeve.
They can also link to the JAXJOX app via Bluetooth, allowing you to “free train” while it counts your reps for you. Or, if you pay a monthly membership fee, you gain access to a series of well-produced follow-along video workouts of varying durations and difficulty levels, which make full use of your digital dumbbells.
I really liked that this was an option and had plenty of fun playing with the app. The video workouts (of which there are hundreds to choose from) are Peloton-esque with a high production value and energetic instructors. However, if you don’t want to pay extra for app access, the dumbbells are still a fantastic home workout tool without it.
The JAXJOX DumbbellConnect adjustable dumbbells are the ultimate piece of kit for anyone looking to start (or continue) strength training at home. Their eight weight options mean there’s plenty of scope for progression, and the maximum weight of 50lb should be enough to challenge most people. Each dumbbell takes up just 19.5in x 7.5in of floor space, the plates sit securely together so I never feared they were going to fall out of place, and the sleek design will look great in any home workout space. They have to be charged up every week or so, which is a minor annoyance, but that’s the only real downside I could find.
At the time of writing, the JAXJOX DumbbellConnects have an average rating of over four stars out of five from 35 reviews on the brand’s website. Happy customers describe them as “simple, durable and versatile”, providing a space-savvy alternative to a full set of dumbbells. A small number of negative reviews say they experienced errors including a refusal to adjust the weight, but this isn’t something I encountered during the testing period.
Core Home Fitness Adjustable Dumbbells (opens in new tab)
These nifty free weights have a clever TwistLock weight-changing contraption built into the handle; all you have to do is give it a twist to switch from 5-50lb (with 5lb increments in between). They’re robust, space-efficient and not too expensive either (compared to many premium models).
Amazon Basics Adjustable Dumbbells (opens in new tab)
If you want to start strength training at home but don’t want to break the bank, these Amazon Basics dumbbells are a brilliant budget option. They don’t have the high-tech specs of digital or selectorized adjustable dumbbells, and changing the weight will take a little while as you have to replace the weight plates yourself before securing them with spinlock collars. However, they still offer a range of loads for under $70.
