Smart Kettlebell
This is the adjustable kettlebell that lets you instantly select from one of six weights with the touch of a button. Unlike multi-piece kettlebell sets that take up extensive floor space, this compact unit has a single ergonomic handle and lets you select your desired weight from a series of stacked plates ranging from 12 lbs. to 42 lbs.
The kettlebell also connects to a smartphone via Bluetooth and a free iOS/Android app lets you track reps, sets, time, and weight used for up to nine profiles.
