JAXJOX - DumbbellConnect - Adjustable Dumbbell Pair - Cool Gray

So, with the pandemic going on and uncertainty of gyms staying opening or closing, I decided to start investing in some home options in the instance the gyms were to ever close down again. This is where the JAXJOX Dumbbells. For one, prices of dumbbells became inflated during this time we are in. The amount it would’ve cost me to get a few sets of dumbbells made no sense when you can have an all in one option like these. These are 15 dumbbells in one when you consider all the weight adjustments you can do with them as a pair. The amount of space saved with this efficient design made this a no brainer. The weight options range from 8 to 50lbs in 6lb increments. This gives a nice sweet spot in weight whether you are trying to cut, bulk, going for light weight with high reps or heavy weight with low reps, the versatility of these are fantastic. Adjusting is easy thanks to the bright and clear LCD screen on the base. The JAXJOX app offers a lot of options itself too, especially for classes. My first class I signed up with was only about 9 minutes long, it was a Strong class with Coach Anthony.. I figured 9 minutes to test these bad boys out, should be cake… wrong… I was dying in no time. Now, I know the pandemic hasn’t been great for me and adding a few extra pounds and being out of shape, but for someone like me who practically worked out every single day before lockdowns, I did not expect this short workout to do that much work for me like it did. I was sweating in no time and watching in real time while the class/video was playing my reps and progress. At the end of it all my data saved and logged to todays today to go back to reference. This is extremely beneficial as this allows you to keep track of your progress and your improvements the more you do classes and do the same way down the road to see how far you've come along. Now, I’ve been going back to the gym since they opened back up however my motivation just hasn’t been there. I feel like I’m dragging along and at the end of my workout don’t feel like I accomplished much or feel the good pain… after just 9 minutes I can say that wasn’t the case. I felt motivated just hearing someone coach me along and push me to get it done. After the short 9 minutes I felt like I accomplished a solid workout. This is my first time really utilizing a coach based virtual trainer like this and I have to say it definitely helped. I would definitely recommend these if it fits your budget. The overall package and synchronization this offers I feel sets it apart from competition. From its versatility, to its comfortable handle and solid build, I really don’t see how anyone would be disappointed. My only negative I'd give this is the monthly subscription to classes. I personally feel somewhere around $5 to $8 a month is more sustainable

I already own Bowflex SelectTech 552 dumbbells, and was curious how these JAXJOX DumbbellConnect compared. I liked how the dumbbells’ weight selection was controlled by an app and these weights included programs to help get fit, so I wanted to give them a try. Setup Setup was easy enough, as one of the dumbbells was easily added within the app, but the other one took some tinkering to get to add. Use I liked how I had the option to change the weight of the dumbbell from either the app or the dumbbell base. It made my workout easy to be able to transition from one exercise to another without needing to be near the base to change the weight. I really liked how the app keeps track of your workout schedule. I also liked how this weight system changed weights to a lower one without keeping an awkwardly lengthened bar where the heavier weights would go. This allows for a compact dumbbell, especially compared to the competition (see photo of both dumbbells at 20lbs). The only issue I ran into with these dumbbells was when I changed from 20lb to a heaver weight. The additional weights in the base were leaning outward, and when I placed the handle back on the base, the tracks did not align properly and there was a gap (see photo). I did not attempt to see if the weight could be changed, but would worry that if it could, the next weight in the series would not be properly tied into the handle and could cause it to fall off and cause an injury. I hope JAXJOX has a failsafe to prevent this, but I was afraid of testing this. Pros Motiving app Training videos within the app Can upgrade to a personal trainer Unlike other quick changing weights, the length is not awkward Cons Weights don’t always align correctly Unsure how longevity of battery impacts useability Overall, I would recommend these weights for someone trying to avoid the gym and needing extra motivation to stay on track.

In the age of Covid, getting a good workout in at home is definitely a challenge. I've used a few different sets of adjustable dumbbells in the past and they each vary in looks and ease of use. I currently have a set of simple ones that I just put plates on the ends and spin a threaded metal collar over the plates to secure them. These are about as inexpensive and low-tech as you can get. The drawbacks are that it takes forever to switch weights and I have to have different sized plates all over the floor. Now the Jaxjox dumbbells simply have a display with + and - buttons built into the plastic base that holds them. Changing the weight is done with a press of a button. The handles have some sort of locking piston inside them that expands or contracts when you are decreasing weight. You can acutally hear it move when it is doing its' thing. Changing weight only takes about 5 seconds, very quick and easy. They also look pretty cool. Other adjustable dumbbells look like some sort of alien torture device. The only issues I have with these dumbbells is that I feel that the handles are a little too thick. They are not hard to grip but if they were a little thinner, they would be more comfortable. Maybe I just have small hands. Also, plate aligment can be an issue at times when you are putting the dumbbells back into the base. Sometimes one of the plates will not line up correctly so you have to be somewhat careful when putting them away, (see photo). This can be problematic when you are fatigued after a heavy set. Something I found strange is that the set comes with charging cables but not chargers so you will have to use one from your phone or other device. Not a huge deal and honestly most people should have some of these lying around but it can be inconvenient if you have to unplug your phone to charge these dumbbells. Battery life is pretty good though. A full charge on these lasted me about 2 weeks. I wish the dumbbells went higher in weight. 50 lbs just isn't enough to work the big muscles effectively. But they work well for most of what I do. Also, picking 50 dumbbells up off the floor might be an issue for people with back problems. It would be better to put these on some sort of stand or platform.

JAXJOX DumbbellConnect™ - Adjustable Dumbbell Pair Included- 1 pair of JAXJOX adjustable dumbbells, 2 USB-C cords, 2 stands Especially with the pandemic happening, and our gyms closed and reopening multiple times, this set of JAXJOX Dumbbells are great for in home use when you can't hit your gym. They're small and compact for the range of weights which is great when you're tight on space. The dumbbells range in weight from 8-50 pounds. All you need to do is make sure they're set in the base, push the up or down arrow which adjusts the weight in increments of 6 pounds. Then the system will shorten or extend the bar and add or subtract the amount of weights set. Pair it with the JAXJOX app for the ultimate experience. It's very easy to use. You can build a personalized profile and then provides very helpful information- can make your own schedule, track your workouts, see your results, take coached classes to learn form and technique. There is also a Premium version that offers customized workouts - $13/mo. There is a 30 day free trial available. I like how they are convenient. You can work out right when you feel like it right where you are. The JAXJOX don't take up much space at all at about 30.5" x 9.5" x 21". The design is very simple and is very easy to use. I like the adjustability and variety of the weights. It's really good for someone that is a beginner or lifting weight is low or up to someone who is more serious about their workouts and lifts daily with a higher amount. My one complaint is that some of the individual plates feel slightly loose when the weight moves around, which makes heavier reps more difficult. So if the plates were completely secure, it would be a little better. But overall, they are great to have at home when you can't hit the gym.

These are great for space saving. I'm impressed with how little space they take up but how much they add to my home gym. There are so many exercises you can use dumbbells with. Switching between settings is fast and easy. I wish they came with a little more weight like maybe up to 60lbs. I can see some of my exercises out growing the 50lbs. Setting up the app was a little confusing but you could just plug them in and go. They come with 2 charging cords but no wall warts. I wish they just connect together then had 1 cord that went to a provided wall wart. The charge is long lasting. I didn't have an issue with durability but I have a concern with durability. It seems like the plastic around the weights could crack pretty easily if you aren't careful. The bar is sturdy and ergonomic. Grabbing around the weights is pretty easy too for some exercise. It would be nice if the base beeped a notification if the weights were misaligned when being replaced. I had a couple times one side would get skewed and miss the slots but the base beeped that everything was ok. For me the app seemed pretty worthless. It was confusing to navigate and required a subscription to access anything useful. The programs and classes it had were good. There were different durations and skill levels. Like you could choose a 10min dumbbell workout or a 60min one. My issue is for the cost of the subscription I might as well pay for a gym membership and have access to all the equipment. The only free part of the app was tracking reps and overall weight lifted. Interesting stats but nothing I personally track. As smart weights these have a lot of potential. The app could be updated with better features. Like paying less for individual workouts instead of a subscription would be better and then having free basic workouts as well. Tutorial videos on various dumbbell exercises. Being able to create your own work out choosing the exercises you want then being able to share that amongst friends. With the rep counting you could set up challenges amongst friends.

I’ve used these dumbbells for a week now. The weights are fantastic, well built, and feel great while lifting. The dumbbells come with two cradles, and two USB-C cables, but no charger. Really? At that price you have to go buy a charger, fail by JaxJox. In my case, I ended up having to also buy another USB-C cable because one of the cables arrived with one connector broken, this can be seen in the included pictures. So after buying the charger and cable, I downloaded the app and connected the dumbbell cradles, this was smooth and I had no issues. I can change the weight in increments of 4 lbs by either the app or directly on the cradles. Weight changes always work well using either method, this is nice. The next issue comes trying to use the premium free trial. I signed up and got a message my premium trial was done without ever using it, so I did not have a chance to try it out. For a product which relies heavily on use of the app, it seems to just have too many issues. I ended up creating a spreadsheet and just log my workouts that way. In all honesty, there are less expensive dumbbell options available, and I’d recommend looking at other options. If the app worked correctly, quality control was better, and a charger was included these might be a product I could recommend. But, based on my experience, I just can’t recommend the JaxJox dumbbells.

Years ago I bought a set of iron weights along with a pair of star-lock dumbbell handles. I thought it would be great to do dumbbell exercises with a variety of weights. Changing out the weights turned out to be annoying, and the star-locks would loosen while I used the dumbbells, making the plates clang together. Eventually my usage of them diminished to zero. Fast-forward to today, and the JaxJox Dumbbell Connect. This is a set of dumbbells with plastic-coated plates that can be adjusted at the push of a button. Each dumbbell sits in its own plastic tray, keeping the weights nice and neat. The tray contains a rechargeable battery and a small LCD display showing how much weight is on each dumbbell. There are also 2 buttons, which you use to increase or decrease the amount of weight on each dumbbell. The set is well-constructed, with a knurled steel handle that connects to the weight plates. With no extra plates attached, the handles weigh 8 pounds, and you can increase the weight in 6 pound increments. Changing weights couldn’t be easier: just place the handle back in the base and select the amount you want with the buttons. Within a few seconds, each dumbbell will beep to tell you that the change is complete. The increments roll over, so that if you press too many times, just keep pressing and you’ll go back around from the beginning. This is actually a nice touch. Using the weights feels very natural. They attach to the handle securely, and don’t clang while in use. Some reviews have stated that it’s too difficult to place the handles back in the base properly so that the weights are straight up and down. It’s true that this does happen on occasion, meaning that the weights won’t adjust properly, but it’s easy enough just to be careful to ensure that this doesn’t happen. One thing I really like about this set is the clean look it has. I’ve seen other dumbbells similar to this that only look good at their highest weight setting. Anything less and it looks like you’re picking up some sort of black fishbone. The JaxJox Dumbbell Connect looks symmetrical and balanced at any weight setting. You can see this in my pictures. You can also see how neat and compact these are in their bases. Anyone who has tried to keep a set of iron plates stacked neatly knows how difficult this can be. The Dumbbell Connect packs 15 dumbbells into the space of 2, and that is a major advantage. The mechanism for changing the weights is motorized, so the connection between the handle and the base is critical for its operation. While it’s too early to tell, this has the potential to be the Achilles Heel for the set. Should the connection fail, or if the battery won’t take a charge, I won’t be able to change the amount of weight on the handle, and it’ll be a giant paper weight. Hopefully these will last a very long time, but it is something to consider as you compare to other alternatives. Speaking of batteries, the batteries in the base can be charged using the included USB-C charging cable. Unfortunately, JaxJox did not include a charger for the cable to plug into, so you’ll have to supply your own. While the handles and weights themselves are very well-built, I can’t say the same for the app. The app promises exercise tracking, goal-setting and on-demand classes, but it delivers very little. You are required to set up an account to get started, which some may find off-putting. I was excited to try out the on-demand classes, but I was disappointed to find that none of them were available without first signing up for a premium membership at $12.99 per month. I expected to at least find a few classes that I could try before paying even more money. There’s also a “programs” section in the app, but there are no programs available for the dumbbells. I checked out what’s available for the kettlebell, and did find what looked to be a pretty good set of workouts put together into a program, but when I tried to preview it, the app locked up. When this app locks up, it REALLY locks up, so much so that my phone is inoperable. In fact, no other app that I’ve ever used has been able to lock up my phone so tightly. Once this happens, you can do nothing but wait for it to clear up enough so that you can kill the app. The app will also lock up if a request to load a class fails. On the positive side, the app does include access to some “skills” videos that show some ways to use the dumbbells for various exercises. Other sections, such as “For You” and “Fitness IQ” are nothing but more ads for going premium. Beyond the video training aspect of the app, I was excited at the prospect of having it keep track of my workouts and progress toward my goals. Unfortunately, the app failed completely at doing that. It registered wildly inaccurate counts for sets and reps, and couldn’t figure out which day of the week on which to place them. I did a set of 8 reps and the app told me I had done 3 sets of 2, 2 and 3 reps each. Trying to use this for tracking toward a goal is just an exercise in frustration. Given that the app features a lot video content (if you pay for it), I thought it would be better to use on the bigger screen of an iPad. Alas, it’s not really a universal app that scales properly for an iPad. Instead, it stays in the phone aspect ratio and cannot be rotated. Overall, the app is a complete waste of time and ruins an otherwise stellar package that is more reasonably priced than its competition. Thankfully, the app is not required to use and enjoy the JaxJox Dumbbell Connect. I’m hoping they’ll be able to work out the kinks in this app in the future. If I thought the app was absolutely critical, I'd give this review 3.5 stars. I really like the Dumbbell Connect, and hope that it will provide many years of service. I’ve seen other reviewers report inoperable sets, so I’m going to keep an eye on this issue. I haven’t experienced anything like that so far. I’m enjoying this set very much, as long as I don’t try to use the app. I recommend it!

Poorly designed. Base does not hold weights straight so its impossible to drop dumbbell into the base and connect both of the left and right set of weights. (One side tips away from the dumbbell and does not connect properly when you put the dumbbell into the base. If you try to align the far side than the first side no longer connects. You can use one hand to straighten the weights properly and then use your other hand to drop the dumbbell into place. This is a problem when you are trying to place two heavy dumbbells at the same time.) One handed, your dumbbells constantly drop into place with a broken connection to one side of the weights. Too expensive to be so poorly designed. It wouldn't take much to redesign a base that holds the weights correctly, rather than letting them tilt so far side to side. I imagine they will have to do a redesign next year to fix this. I would definitely wait till then when the product is ready. The app is kind of cool how it can track total reps and weight. But currently it constantly confuses picking up the bells from the base and walking around the room as multiple double reps. Literally half of your reps will be incorrectly counted as 10 separate double reps that weren't reps at all. So doesn't really work in practice.
