Incredibly compact and ergonomic, the PowerBlock Adjustable Kettlebell packs four weights into its contoured shell. With a handle diameter of 32.77mm, it’s easy to get a good grip during workouts. Quickly swap between 18, 22, 26 and 35lbs (8, 10, 12 and 16kg) with the steel selection pin, which is magnetised to ensure it doesn’t come loose mid-kettlebell swing. The weight is printed on the side of the kettlebell, so it’s clear at which level you need to insert the selection pin for your desired weight.
