The Good Modular weight cylinders inside the KettlebellConnect transform it into six kettlebells -- in one device. Press the button on the rechargeable, battery-powered base to add or drop weight with ease. The kettlebell logs your workout on the JaxJox app via Bluetooth; you can pair your Fitbit account to the app, too.
The Bad At $349, this kettlebell is awfully expensive. My Fitbit stats didn"t update consistently in the JaxJox app -- sometimes it said I hadn"t walked any steps at all (when I obviously had).
The Bottom Line The compact JaxJox KettlebellConnect is a convenient, albeit pricey, weight system that makes it easy to track your reps, sets and more.
