Impressed by the feats of strength he saw Bulgarian shepherds perform at street fairs, former champion wrestler and coach Ivan Ivanov created the Bulgarian Bag system.
Designed to mimic the hefting of a heavy animal, the challenges of “bag work” involve every muscle, and the shifting wool and sand contents demand continual adjustments. These movements promote central-nervous-system integration, and thus, better agility, balance and endurance. Leather bags start at $128 and come with an instructional video; watch other training videos here: http://ibbconline.com/video/hip-extension. Available at www.suples.com.
