    After using the JAXJOX Kettlebell Connect extensively for over two months, I can confidently conclude that this is one of the most versatile pieces of equipment for the amount of space it takes up that’s currently available for Kettle bell training. It is not only incredibly versatile, but it’s also extremely space efficient for in home use and for traveling fitness professionals. At a push of a button you can adjust your weights starting at 12lbs going to 42bls at 6lb increments. Simply put if you had to have one piece of equipment for weights be it in home or a traveling fitness professional the JAXJOX Kettlebell Connect is the only piece you need.

    If you like working out with kettlebells, then you must buy this product! Unlike any other kettlebell- digital display, cool design, all your weights in one place.

  3. Becky

    I love my Kettlebellconnect! It doesn’t take up too much space in my house as my other gym equipment, and the functionality is so cool! I like how easy it is to increase weight mid workout. Plus the design is so modern compared to other kettlebells out there. Highly recommend.

  4. Nick

    This kettlebell changes weights extremely fast and replaced my slow manual adjustable kettlebell that took way too long to change weights. The workouts are probably the best part. They are challenging, fun, well thought out and most importantly effective.

  5. Amanda

    I love the kettlebell as it is very easy to use. It works very well with the app tracking my every movement. All the data on the app is accurate which is good and it is helping me to reach my fitness goals with the different curated workouts I’m doing shown on the app. Highly recommend this product!

  6. Meredith

    KettlebellConnect is a game changer! I’m loving incorporating it into my workout routine. I’m seeing results already. Plus fast shipping and great customer service.

  7. Justin

    The Kettlebell Connect is a huge space-saver and endlessly useful. It changes weight quickly and the app been giving me accurate metrics. You won’t be disappointed.

  8. John

    The KettlebellConnect feels like the future of fitness and exercise equipment. I’ve been tracking my cardio for a while and love seeing the progress that I’m making, so having the ability to also track my workouts with weight is a huge benefit and helps keep me motivated. I was able to quickly and easily connect my kettlebell to the JAXJOX app to track my weight, reps, and progress towards my goals. The adjustability of the KettlebellConnect is unlike any other adjustable kettlebell that I’ve ever used – just set the desired weight on the screen and in a few seconds the weight is set. Really cool!

  9. Liz

    I was looking for a versatile piece of gym equipment that took up minimal space. I was hesitant to spend this amount of money on a set of weights, but I have to say that it was well worth it. The technology is great and the weights change quickly and flawlessly so there is no downtime in my workout. The app is great too and I love that it works seamlessly with the Kettlebell Connect to keep track of my progress. I hope JaxJox offers more products in this line in the future!

  10. Sydnie

    I love this kettlebell. It’s so easy to incorporate into my at-home workouts. I appreciate the fact that there are multiple weight options inside one bell and i don’t have to go out and purchase multiple kettlebells which would take up a lot more space. Highly recommend!

  12. Jamie lynn Campbell

    I just wanted to say Thank you! I’m impressed with these kettlebells. 5 in 1. Easy to use and I can track my achievements through my phone and the JaxJox app. Great workout. I’ll probably buy another one for my son to use.

  13. Kayla

    Absolutely amazing product. I love that just 1 piece of equipment can adjust to whichever weight I need to get the most out of my workout. Not only does it hold charge for multiple workouts, it tracks and syncs right to my app so I can see just how hard I worked. Thank goin JAXJOX for a product I can’t live without and highly recommend.

    The KettlebellConnect is amazing! It’s so easy to use and feels just like a standard kettlebell. I started incorporating it into my HIIT workout routines and couldn’t be happier with the experience. Awesome product JAXJOX!
