Frequently Asked Questions

What is the difference between the KOREBALL and a kettlebell?

KOREBALL™ is the only collapsible, travel friendly, weight adjustable kettlebell workout system. The state-of-the-art, patent-pending design of the KOREBALL is a hybrid of traditional kettlebell and medicine ball training equipment. Whereas a traditional kettlebell is made from metal and only has one handle, KOREBALL has dual comfort handles and is made out of Santoprene rubber, making it more comfortable, safer and easier to use than kettlebells or traditional medicine balls which have limited range of motion and are often difficult for users to hold on to for longer than a few minutes at a time.

How is the KOREBALL Workout System inflated and deflated?

 KOREBALL is patent-pending and the only kettlebell that comes collapsed in a convenient and compact carrying bag. The water or sand filled, leak proof, bladders are weight adjustable when filled.
