Adjustable Kettlebell by CAP Barbell
There are several varieties of adjustable kettlebells on the market, but this edition by CAP Barbell may be the coolest of the group. The difference is almost invisible, which to a hardcore workout enthusiast is perfect. The CAP system looks like a traditional kettlebell since the variable weight plates hide inside. You can vary the weight from 20 pounds to 40 pounds in 5 pound increments just by turning a dial. Of course, you have to put the kettlebell back down on the pile of plates for the dial to work, but that is a minor concern. This in the fastest changing adjustable kettlebell you can find, which makes switching weights and exercises a breeze.
The Adjustable Kettlebell from CAP sells for approximately $185 on Amazon.
