Meet the HYPERBELL: a clever fitness tool that turns your dumbbell into a kettlebell, macebell, and curl bar. It clamps onto any dumbbell, including adjustable ones, to let you perform a wide variety of strength training routines.
Each clamp can hold up to 100lbs. You can use this in multiple positions for weight swings. The kettlebell handle and bar are easily interchangeable to save you time as you change up exercises.
