Invented in 2005 by legendary Wrestling Olympian Coach Ivan Ivanov. The Bulgarian Bag’s shape allows for both upper body lower body and core training while emphasizing grip strength. The three different types of handles allow athletes to execute a variety of exercises by using different grips. The Bulgarian Bag is a fitness tool of the next generation. Being a movement based piece of equipment, It incorporates all primal movement patterns that mimic natural movements. What makes the bag unique is that it’s one of only a few exercise tools that cover all planes of movement under load. It’s a functional training tool that creates power and neurological integration.
