Product Summary

The Jayflex Hyperbell is a new innovation in the industry, allowing you to transform dumbbells into a barbell or kettlebell with its patent-pending device. 

The Hyperbell Bar can hold up to 200 pounds—simply attach your dumbbells via the multiposition handles and perform any exercise you would with a barbell. It’s made of industrial-strength steel with commercial-grade rubber grips and foam inserts in the polycarbonate clamp. A quick-lock collar secures the dumbbells in place.

The Hyperbell Kettlebell works much the same—attach a single dumbbell to the handle and use up to 100 pounds for swings, thrusters, or cleans. The kettlebell has a textured handle, as well as the same quick-lock collar and clamp system.

The appeal of this product is that it eliminates the need to have sets of fixed barbells, kettlebells, and dumbbells, thus being a space-saving and more budget-friendly option. And at only $179, it is much more affordable than buying multiple sets of weights. Hyperbell comes with a 30-day money-back guarantee as well as a two-year warranty.
