== History ==
The Bulgarian Bag was invented by Ivan Ivanov at around 2005.〔Connie Cook (The "Bag Boy of Fitness" Challenges You With Bulgarian Training Bags ) San Diego Downtown, Aug. 5, 2009, Retrieved Oct. 5, 2010.〕 Ivanov, a former Bulgarian Olympic athlete,〔(Ivan Ivanov Bio ) TheMat.com, Retrieved Oct. 5, 2010.〕〔Gary Abbott (Ivan Ivanov named 2009 USA Wrestling Coach of the Year ) USA Wrestling, June 18, 2010, Retrieved Oct. 5, 2010.〕 was working as a U.S. Olympic wrestling coach at the Olympic training center in Marquette, Michigan and was looking for a training tool that would allow his wrestlers to improve explosive actions〔(Definitions of Weight Training Terms and Concepts ) Women's Weight Training Programs, Accessed Oct. 6, 2010.〕 and dynamic movements involved in pushing, twisting, swinging, pulling, bending, rotating, squatting, lunging, and throwing.〔(Why was the Bulgarian Bag developed? ) IBBC Online, Retrieved Oct. 5, 2010.〕
Ivanov was inspired by the tradition of shepherds performing strength acts with sheep and goats on street fairs in his native Bulgaria. The shepherds were often forced to carry lambs and weak sheep around their shoulders when they were wandering with their herds, and were showing off their strength at festivals. Ivanov based the design of his tool on the body of an ovine and saw its use as a modern interpretation of the old tradition.〔(Bulgarian Training Bag -- History ) Suples,ltd. Inc., Retrieved Jan. 30, 2013.〕
Although the Bulgarian Bag was initially designed for Olympic class wrestlers, it came to be adopted by fitness trainers and professional athletes for its ability to increase muscular endurance and make weight training more versatile.〔Kyle Brown (The Bulgarian Bag: Extreme Training for the Next Fitness Generation ) NSCA's Performance Training Journal, Issue 8.3, May/June 2009, pp. 11-12, Retrieved Oct. 5, 2010.〕 One of the first advocates of the Bulgarian Bag outside the Olympic wrestling circuit was fitness specialist and retired Navy SEAL Stephen Nave. Along with Ivan Ivanov they formed the (International Bulgarian Bag Confederation ) to educate the public and offer advanced instruction to individual consumers, personal trainers and fitness establishments.
